Excellent info. I have done the same swap back in 2016 and you mentioned a few things that I had not thought of doing. Thanks for making and sharing this!
It's still difficult to find a coyote with all its electronics for a good price on a small budget. The mark is still a good alternative to swap. And to spend the amount on a stock coyote, is still a head scratcher imo. I get asked why didn't I go with the Cobra intake. And simply put, cost. But also longevity. I planned on a different setup later on. And new spending the cost for that intake at the time was just not feasible. On the up note, I like the conversation peice, the intrigued look on folks faces at shows. I enjoy that.
@@agencyheadquartersdc4568 Or just a mach 1 and save your safe the problems . The price has come down on some of them with high miles but everything you need is there to start with.... In the long run a rebuild could cost less.... With the Mach you get bigger brakes a 3.55 rear..
Great vid. I have a 1996 4.6 2v non PI want to switch to 4v and PI intake, Not having any luck finding 4v cylinder heads for 1996 that is a 2v now, kits. Body and interior are cherry, zero rust, 49k miles, motor is my only concern project.
on a pre PI car you will need heads as well to use the intake. I would use late 02-04 for parts. the compression will be 10-11:1 on the non PI engine. it's all plug and play really. if cams are in the budget I would go with something mid to high and throw gears at it.
Motor runs good just wanting to juice it up a bit. Thinking of check some wreck lots, try find low miles but don't matter, just not sure how to tell looking before I remove, that it's PI heads.Changing to 4V heads seems like more effort than I want.
Ford part number 8005 radiator for GT, DOHC , and DOHC s/c. so... just because an aftermarket sells you a all aluminum radiator does not mean it was when it left the factory.
Well all my wiring is almost installed. Im trying to change the heater core while the dash is still out but not having much luck pulling the old one out. Im also having an issue with the 99 cobra tail light wires. Since mine was a v6, i have the all red tail lights which have a 4 wire plug. The cobra harness has a 5 wire. Bot sure how to make that all work. Part of the reason i changed the body harness is because i was told it had to be changed. The other reason is because i had a bunch of extra wiring that i wanted to get rid of from installing the mach 460 sterio. Now that all of my wiring has the mach 460 wiring its alot cleaner looking of an install. I even changed the door harnesses for the mach 460. Just trying to do this the correct way. Any cut wires or plugs i found were cut from my old harnesses and soldered onto the new wiring along with heat shrink tubing. Anyway suggestions on the tail light dilemma?
Just bc it will fit doesn't mean it's what actually came on the car. I'm sure the hose locations are the same, but cobras had an uprgraded version over the GT www.svtperformance.com/forums/showthread.php?746766-Mishi-Fluidyne-03-04-Cobra-radiator
Ford part number 8005 radiator for GT, DOHC , and DOHC s/c. so... just because an aftermarket sells you a all aluminum radiator does not mean it was when it left the factory
I actually swapped out all of the harnesses for 99 cobra along with 99 cobra ecu and 99 cobra gauges which came from the same car. Im concidering using the mark intake as it seems alot of the 99 cobra engine harness plugs are almost in the exact same place as the mark viii. And i will be able to use the 99 cobra fuel rail. And keep the fuel rail pressure sensor in the same place.
This is some what correct but the rail is not plug and play. It has to be modded. The tabs have to be removed and the mark viii tabs have to be mounted. You may still run into PATS issues because the BCM body control module. Not a 100% but you may run into issues. That's one thing when doing a swap in that caliber, is you have to swap everything. Just remember you will still want it tuned because the engine though a 4v is different from the 99-01 Cobra 4v.
32vNomad my car used to be a v6 so thats why im doing all of the swapping. i used what i did because i was told to make a mark motor work with as little modding as possible i had to use all 99 cobra electronics. Where is the BCM? I was told only the gauges, ecu, and key make up the PATS.
That I cannot answer definitely but if it's a aode then yes but tail shaft may be different, etc. Mine is a manual so for me, a pilot bearing had to be added to the crank.
I'm in the middle of a 4v swap from a 97 cobra into my 03 gt and have ran into a couple of issues primarily the fuel rail, it seems you are the only guy that has posted a very informative write up about it, it has helped me out a lot thus far but if any way possible can you email me so I can ask you a couple of questions that would be awesome. thanks in advance!
+Bobby Romero the fuel rail used was from a cobra/Mach 1. The tabs from both we removed, and the mount tabs from the mark viii were put on. Zip ties and JB weld. The setup works well, I haven't had any issues. I would suggest taking a look at Warhorse Mustang Club on Facebook. My write-up is on there alone with photos of the rail. I can also answer questions faster
+32vNomad I have tried to look up the page before but since I don't have a Facebook account I can't view the full page, I ordered a fuel rail from an 03 cobra and did the same thing but didn't account for the frps and the upper intake cover is hitting it not allowing it to seat. I don't know what other fuel rail I could use with the return less set up in my 03?
+32vNomad is there anyway you can email me? bobby.romero23@gmail.com so I can send you a picture of my issue. My cobra intake manifold is hitting the frp sensor on the 03 cobra fuel rail. I don't know of any other way of using return less besides the fuel rails you stated in the write up but all of them have the frp sensor in the same position.
Very nice write up! Was wondering what internals these engines had. Was there a difference in hp from Mark 8 to Mach 1? Also did you say you switched polarity on every coil pack? Thanks for the write up and any help.
I like the 4v. The potential is great. I've since this video have swapped to a c head config. (Didnt seem to change power much) I have also turbocharged it. 8lbs with a single 66mm mp made 510hp 532tq. The MP turbo was journal bearing. Got a 67mm cbb now. Hopefully this spring I'll get back on the rollers. Had a oil line failure my last show, caused some smeared mains. I post most vids on Instagram @32vnomad got a short roller vid up.
actually no the only difference is the fwd Continental dohc which the block has no provision for the starter placement on the rwd. And to add that the block you see in this video is that of a 1993 dohc intech. which has a 2002 tr3650 behind it. bolt patterns are all same for rwd 4.6l.
wow thank you for this vid! i have 4.62v 2003 GT my goal with it is 400 hp. god knows i would love a 32v but i think 10p of boost on a turbo might be the cheapest route
daveyhouse yeah me to, there was more of a push but that was 4yrs ago. I in process of part collection for a refresh and C head exchange. the AF is from a k&n kit but the guy I got it from didn't have the surround. never really bothered. but yes I have it on my list to do. 😊
+32vNomad how did you use the coolant temp sensor and the cylinder head sensor on the 4v swap I no the 2v has them bout but on the 2v the cylinder head temp sensor goes into the driverside cylinder head under the intake and the 4v goes on the coolant hoses by the alternator
+modded Crown Victoria 2009 p71 flex fuel the mustang 4.6l doesn't have the head sensor. The crossover tube for the mark engine has two outputs for two sensors one I believe is for the gauge the other one I believe it's for the ECM you can use the passenger side hole for the coolant sensor. Using a Mach 1 or Cobra setup (C head) the crossover tube has the sensor on the drivers side. The coolant connection will have to be lengthened. I have however thought about wiring a separate gauge for the head temp.
how much more work would it be to do a 5.4 4V Navi swap? they seem to be a little more common and sometimes cheaper as well even compared to a Mark motor
Im gonna be doing this same motor, however my motor will have the 98 cobra intake manifold. Im going from a v6 to the mark vIII motor. Im gonna assume once I change all my harness its just a matter of changing the parts you mentioned for the mark motor to fit the Mustang and it would be plug and play f4im there?
If your doing a new edge the fuel rail would be done in the same manner. Unless you want to redo the entire fuel system. I would suggest modding the returnless mach/cobra to fit the 98 intake.
Same would apply. Depending on the year will be dependent on the part list. If you in a new edge then you'll need some things I'm not sure if the v6 has the hydro boost braking but you'll need that. And all gt lines. You need GT wiring as well, it would be the cheapest. Idea in your case maybe a mach 1 or cobra pallet with engine and ecm harness. The car would need a tune regardless to deactivate PATS but it shouldn't be an issue.
well price may vary. Mark engines are decently priced, most u pulls are scrap priced if you pull it. but then you have to think of your build and what you want. like if your going to forge the bottom end, etc. it can get pricey. it's all about where you get the parts and what you end goal is.
hello, first I want to say thanks for the video it's really usefull, second, I know this video is a little old but I still want to try to reach you and ask you: what do you mean by reversing te cables? thanks in advance.
+mike broswood well first thank you. To answer your question if you talking about the COP's then yes you well need to reverse the polarity of the connector. As the 2v wiring is opposite. If you are asking About the alternator that is also something you need to reverse when using the Mark setup. If you are using a 99/01 or Mach 1 setup the u need just the 4v pigtail and keep the wires the same. In the description there is a link to download the write up. As well as others. There is also another vid I have that answers some other questions. Hope this helps.
dude thats sweet im doing it but from a v6 to a mark vii yeah i know i have to get the cross member an upgrade my front end but im getting the whole car for 600 jest a bad tranny but i bought a t45 one fro the swap
This looks great! I have a 2002 3.8L, im wanting to buy a wrecked 4.6 of a similar year to use as a donor car and swap everything over. Im concerned about the vaccum lines, should it all be pretty standard to swap as long as I have the donor car there? Any tips on it? Thank you.
+Austyn Oconnor the vacuum lines are very simple. You can also check with NPD they have the vac stickers and under hood info. Now are you looking to do a 4.6 sohc or put in a dohc.
32vNomad. love your video and what you did with your car. My question is ive got a motor out of a 2004 lincoln aviator. Will it plug and play like yours did out of the mark viii
+Cleve Wilks thank you. As far as the aviator engine it will somewhat. The intake is the factor for it. If you use the engine with a mach intake/rail/alt/etc it would be an easier swap. You would need an oil pan as well.
GT harness is a bit differ but no it is into the main bulk. But nothing need to be modded for the injectors. Unless using ev6 then you can change connectors or use adaptors.
Hey bro I love vid. I got a 00 gt I just did a 4v swap from a 2001 cobra and I was just wondering to extend the coil wires did you splices them and used extra wire. Then sottered and heat shrink them
when doing the coil setup, you should wire one coil complete at a time. I start at the coil side and work back to the harness. use good solder, and heat shrink tubing. take your time.
Seems like a lot of trouble for 40 horse power. Maybe if you've got a blown motor already needing replaced. Could have the 2v at 4v power with bolt ons and 400+ with FI. 4v can't really handle much more power than the 2 in stock form anyway so no real benefit between the two. I do love the bigger motor though, how can you not.
It's called power potential. Stock for stock 4v better choice, even a forged bottom end upgrade between the two aside 4v a better choice. Boost the 4v and 2v and still the better choice. But to each his own.
@rob johnson in my video there is a link to a write up that goes with this. It will help you on your way. I can also be found on warhorse mustang club on Facebook as well as @32vnomad on Instagram.
IIRC, don't 99+ GT's have a returnless style fuel system? How did you adapt the return style fuel rails from the mark to the returnless system on the GT? What about the IMRC's?
The fuel system is still returnless. I used at mach/cobra fuel rail. I used the mount tabs from the mark rail to use the rail with the mark intake. Cut the tabs from the mach rail and remounted the mark viii tabs. I have ev6 24lb injectors from a mach as well. I'm going to edit the description to include a link to my Facebook version of my write up. There are photos as well.
Im in the middle of a horrible swap and I'm curious of what fuel rails you are running I have a 93 Lincoln Mark 8 long block with a 98 Lincoln Mark 8 intake I'm having feel real issues.. hooking up to the factory fuel lines
I have a check battery light in my p71 swapped crown Vic. But I changed the pigtail. You said switched the wiring, there's only green (ground), yellow (power), and white (dummy wire). What do you mean switch the wiring?
The pigtail has a signal wire and power wire and neutral I believe. If you are using a mark viii engine with its stock alternator. You'll notice that the plug, plugs in reverse. So you need to switch the wires at the pigtail in reverse.
Nice job! Please help me. I did the same swap on a 96 gt. I can't get it to crank and it leads me to believe its a ground wire issue. What grounds did you hook up and how did you fix your alternator. I have the pigtail for the 4v but it has three wires and my 2v has only two wires
awesome video man. just wanted to ask you one thing just to make sure i heard you correctly. you said you used the stock gt wire harness, but swapped all the sensors that were different from the 2v to the 4v, correct? any way you could be specific on which sensors were different? do you have any issues with a check engine light doing that or anything on the swap? and sorry last question, did you have to change anything with the computer?
the sensors were just swapped from my 02. the 93 Mark sensors some were different connections. I used all my GT sensors with the exception of the fuel and that was from a cobra.
Nice video! Im in the process of doing an aviator swap on my 99 gt. Did you have any issues with high idle? I dont appear to have any vacuum leaks, however it will run an appropriate idle with the TPS unplugged. TIA
If you keeping the Mark VIII (2nd gen) intake, make sure to get the throttle cable and cruise if you want that as well. While your looking for parts get a mach 1 valve cover set.
32vNomad I can’t use the valve covers that are on the 98 mark motor? Also what year cobra oil pick up. How does the tune work? Do I send out my Ecm? I’m confused a bit.
Well I would get a new pump from ford racing. It comes with a new pickup. As far as the valve cover is concerned. The heater hoses in the rear on the 99-04 GT are quick connect hoses. The hoses can be reused with a mach valve cover because the breather is in the front. The mark cover has the breather in the rear making the quick connect for the larger line unusable. Also the engine has more of a rub point. Its best to get the covers when getting parts. The ecm needs a tune from a tuner. You will need to have a sct tuner and a shop that can either email or dyno tune.
The ecm is not plug and play, the cobra has different pinouts and would need to be addressed. But also a tune would still be needed for the security to be disabled. With the oil pump just get a hi flow melling or a ford racing oil pump. You can get one form lethal or american muscle.
Hello I Am Working On A Similar Project With A 98 Mustang GT But I Can't Figure Out What To Do With The 2 Butterfly Throttles On The Back Of The Intake I Have The Box With The Cables For It But Trying To Figure Out How It All Goes Together Please Help 🥺🥺🥺🥺🥺
What intake are you speaking of? Are you speaking on the 2v intake or the IMRC on the 4v? If its the ladder I deleted the butterflies and ran it. Since the 2v doesn't control them any way.
@@NomadGT The 4v I Have A 98 Mark 8 Engine Going Into A 98 Mustang GT I Heard Somewhere That You Zip Tie The Butterfly Throttles Open Didn't Know How True That Is Or Is There Some Type Of Kit I Have To Buy I'll Appreciate Any Advise That You Could Give Me Thanks
Those 4.6 mark Vlll engines are Huge!!! They look like big blocks lol.. well compared to an LS engine. Btw you can check out my Lincoln mark Vlll on my UA-cam
Hey I realize this is from years ago,but hopefully you will still see this. My 2002 GT engine (4.6 2v) has a rod knock and we are trying to weigh our options as to what we are gonna do. How much do you think it would cost to swap in a 4v like yours? I have a buddy that can do it for 50/hour so I'm just trying to figure out if I should upgrade to a 4v or find a refurbished 2v to dump in the car. Any insight on the subject is greatly appreciated! Thanks
Well the cost will be the engine and tuning if you use the GT electronics. You can find mark viii engines for a good price. The issues with cost is what your end goal is. Is it just, a daily or something you wanna put power in. With the 4v comes a higher cost when adding power but not much. Being that I did all my own work in this swap and build (except machining), my cost was low. What are you looking to do moving forward?
@@NomadGT I've actually fully decided to go with the Mark VIII swap. I guess some questions I have right now are. I found a post on CL for a complete 4v swap with a bunch of listed parts. I'm not buying everything he has listed. But he does have a Mark VIII motor with 126k for $500 and a 96 Cobra Intake manifold w/imrc plates and throttle body for $350. Is that a good deal?
If that intake comes with the throttle cable and brackets then yes. Some try to sell just the intake for 350. The engine sounds like its priced right. You can find me on Instagram be sure to follow the links to my write up. It should help alot.
@@NomadGT Alright thanks. I'm reading over your facebook write up right now. What would be the best way to contact you for questions if you don't mind me asking? I really appreciate your help!
josue vasquez if you have a cobra I would not purchase GT hoses. Mach 1 and the Cobra share the hoses. the hoses on this swap are Mach 1/Cobra. I at first a 2v but had to cut it apart to use the lower. I've switched to a Mach 1 lower since then.
Hey how is it going, I'm in the process of doing my swap but I have a couple of things that I'm not sure about, I have a 98 mark 8 and I'm using the 98 cobra intake manifold with matching cobra fuel rails. Do you know what exactly I need to do to convert the cobra fuel rails to return-less? I also have my 03 GT water pump, is a short water pump, will this fit here? and I have steeda UDP will those fit into this motor as well? if you coul contact me through email that would be fine as I dont always check on here. thank you
Quick question, I got a 95 f150 with a 4.9l 2wd 5speed and am swapping into a 95 4.6L 5 speed cobra engine. Where could I get a harness made for it to fit on the truck??
You could use a harness from a 4.6 truck. Basically ecm and engine harness. As far as making harnesses is concerned, I wouldn't know where to send you. All my harness modifications that were done I did. I would look to doing an engine and ecm harness swap, and modify the 96 harness as we would for the mustang. The fuel system maybe easier for you as I think you have return style setup.
What engine harness did you use? GT OR MARK HARNESS? Also did you use the existing Mark oil pan? Or did you have to swap oil pans? Do the Lincoln exhaust manifolds bolt up to the fact GT H pipe?
All parts you listed are mustang. The ecm is GT. In the link below the video is a download to my write up. Also you can find me on FB under warhorse mustang club. I have it linked there as well.
@@NomadGT thank you for the info. I read the FB information page on this write up. Couldn't find anything about the stock Mark exhaust manifolds. Will the stock mark 8 manifolds bolt to the factory GT h pipe. Thanks again
What did you end up doing with the knock sensors? Also where can i find the mark throttle cable and the mark cruise cable? I was gonna use the 98 cobra intake but it seems like i would have less wiring to do if it stuck with the mark intake. Im running the 99 cobra wiring front to rear including the engine harness.
The Mark cables you will have to find a donor (97-98) in a yard. I dont have cruise with my Mark setup. But with my C head change with Mach intake ill add back in cruise. I did not use knock sensors as I used the GT harness and ECM. It was a lot easier then messing with the Cobra wiring. The only way (for me) that I could see doing that is if I could get a donor car and swap dashes as well as modules, etc. If you have a GT set up its the easiest route to take. The car will run on the GT ECM, and can be dyno tuned.
You know I have to apologize, I was reading some of my past comments and realized you went a route (with wiring) that seemed a bit over. But here is a better answer. With you doing a complete wire swap, I'm assuming dash wiring as well the knock sensors you want are going to be from a 99 Cobra. See the technology changed a bit after 98 so I would suggest. That you do go with the C heads and 99 Cobra intake. But if budgeted you could run the 98 intake with the heads you have but you won't have the IMRC so remember you will have to delete them. Overall the best choice for your project would be getting a set of Mach heads and Intake or (continental heads 99-02 cheap from local yards) but still get a Mach intake.
Wiring wise im going from a v6 to the v8. However ill be doing 99 cobra wiring with 99-01 cobra ecu, gauges, and key for the pats. I should be good to go electrically yes?
I would think if you are doing the complete swap, you should be OK. I myself if doing all that then I'd do the dash swap. I know of a guy that had did a mark swap in his v6. he used gt wiring and ecm. not sure what all he did.
Cobra plug wires will work I have a nice set of rear black Msd 8.5 mm like new and 2 new MSD cool packs 4-tower.but your cobra wires will work fine.written by Tom Hanson not Shelley.
The GT does not use knock sensors. By using the gr harness you eliminate their use. The alternators pigtail needs to be changed from the 2v harness. Also the alternators are different from mark to mach. You will need the correct one per intake setup.
This might be too late but I’m currently doing a swap and read your write up about the wiring. If you run the cobra harness on the engine do you only have to change the pcm or do you have to change something else ?
Yes. The Cobra engine harness pinouts are different. You would need the ecm harness as well that goes to the firewall to the ecm. It's just easier to mod the GT harness to work. Just take your time. I goto junk yards and pull factory harnesses to use when doing repairs or projects like the swap. Having oem harnesses is great because you can keep the same wire color and guages.. But to recap you would need the ecm as well from a Cobra along with the ecm and ecm harnesses.
Question? I have a 2000 Lincoln continental 32v intech alum 6 bolt mains. I want to swap to a 03-04 terminator setup that motor is. 4 bolt mains but I read they are the same motor just cast iron. I need your advice will it work finding a roller
the block you have is set up for FWD. the issue is going to be fit. the blower all the parts that bolt on the front of the engine as well as HP/TQ output to the transmission. from what I know the fwd block isn't usable in the rwd, so I would think the same would be true of the opposite. So in all I dont think a swap would work for you. I would look into more of a NA build with maybe spray. opon digging a little I wasn't able to find much info on that sort of swap.
Nice. I've a 1998 gt. I have in my garage a 1998 Mark viii complete engine. 121k on it. Would it be ok to just do a head-intake swap, or would you recommend a whole engine change? I'm aware of the teksid block and crank.
Well if the engine is complete then it's best to keep it that way. The pistons are different in your 2v and would lower compression. The swap is not to difficult. You would need some 98 cobra parts. Fuel rail mostly. You have to custom the egr to work with the mustang exhaust. Or have it turned off in a tune. You need the Mark throttle cable unless you use the cobra intake manifold.
To make it easier for yourself you should get yourself valve covers from a mach 1 or 99 and up cobra, to use cop. Check out my link for my write up. I have some parts you'll need. I myself started with a 93 mark engine.
I am swapping 2000 mustang gt engine with 2001 mustang cobra i have gt harness that does not fit the 2001 cobra injector pigtails any thoughts or suggestion is much appreciated
The injector pig tails are probably unscar connectors or ev6. You can either get ev1 to ev6 adaptors or get them from a junkyard as I did and swap them. Also I think the link for the write up is in the description it will help you further
I have a 98 mustang gt with blown motor will the 4 valve motor be a direct fit and plug and play and is there any specific parts that are required in order for it to work also my 98 gt is a 5 speed idk if that would mater or not
Well the 4v fits, as it's on the 98 cobra as well. Plug n play not so much. You could get all the parts from a Mark VIII but you would need to get some things from a Cobra. You would need the exhaust manifolds, heater core hoses, you need the mark throttle cable and cruise if you wanna keep that. You can use the GT ecm and wiring but you need a tune. And being a Mark VIII is auto you need to install a pilot bearing into the crankshaft. There is a bit more but look up warhorse mustang on Facebook. There is a write up that can help and it's easier for me to answer any questions.
Sry for the delay I'm not receiving my notifications. But yes if you have a Windsor and are swapping to a mark then you will need a 6 bolt flywheel. If you get a cobra 4v they are 8 bolt. Other than that no. Not that I can think of.
I'm not familiar with the crown vic, but I would say wiring will be the same as I did but for parts I would look at a marauder for a parts list. I would use a mark viii engine with 00 continental heads (tumble port) and a marauder intake. So the wiring you would mod from the crown vic. You would remake the coil harness wiring and get a set of 4v coils. A set of 97-98 mark covers or marauder covers. I would keep your crown vic lower coolant setup and run a 4v crossover delete. Headers I would look at marauders as well. I would do best to imitate that.
No but those won't fit on b heads. You'll need c heads. Once you get those its just plug n play. The rail everything. Just as it would be on a 99/01 cobra or 03/04 mach 1. If you stick with the mark setup you need to mod the tabs for the rail. I used the tabs from the mark viii rail onto the mach/cobra rail
@@NomadGT okay cool, friend of mine has a spare set of C heads and also found a 04 Mach motor for $500 that had a knock so I should be set either way. Been wanting to do a 4V swap, would be more fun in the end and more potential than the 5.4 2V swap I was thinking of doing for simplicity and cost
I previously commented about my 2000 gt mustang and swapping the motor with a lincoln mark 8 motor. do I need the mustang injectors because I have the Lincoln injectors on and it doesn't want to crank I have fire and gas on the line. what do you think I need to do? the mechanics don't want to work in it because I put it in myself.
+Rupe Pavon sry for the delay. I'm not getting notifications for some reason. As for your issue. Let me understand your car is cranking over and you have fuel and spark.? Questions for you. What harness did you use? Did you reverse the polarity of the coils? Are the injectors working?
Did you have to upgrade fuel system or was gt fuel pump strong enough I did a 01 cobra swap into 00 gt run fine at idle or when revving but bogs and stuttering when driving a guy did a tune but I can't verify because I wasn't at shop I'm stock beside bassani x pipe jlt big cold air flow master and nos
There was no change for the pump. the GT and Mach 1 have the same pump. the car even without a tune did not have fuel issues other than injector mass meter mismatch.
+Tyrell Woodberry the maf meter is for 19lbs injectors. you would need a tune for 24lbs injectors and a Mach maf. if possible I'd run 30lbs and have the Mach mass reconfigured for 30lbs
Hey my friend! How are you? I like your video, that engine looks really clean! I have a question for you, I am in a big problem that I can not solve, I am looking for help maybe you can help me, I have a 2000 mustang gt, originally it is automatic but install a 98 lincoln mark viii 4v engine and a manual transmission t45 of A mustang gt, the problem I have is that in cold start the engine is very difficult, it loads a lot of fuel to the degree of gas spitting through the exhaust, when I get it to start shaking and the smell of too strong a fuel in the mixture is strong! When I go out to handle it I can not feel the 290 horsepower that the engine has and when I reach a red light I have to be aware that it will not turn off because if it turns off it is difficult to turn it on again because it contains too much gas! What do you think is going on with my Mustang? Is it a sensor? Is it the automatic to manual conversion? I hope you can give me some advice, I really do not know what to do! Thanks for your time to read this message and I hope you can lend a hand to solve this problem! Thank you very much!!
+Luis Amaya well let's go back. Tell me about your swap? Did you swap pcm? Did you have it tuned? How did you do the fuel sys? If you on Facebook you can find me on warhorse mustang club. There you can post pictures and stuff. And will be easier to help you.
+Luis Amaya that's alittle nuts. Let me ask you how did you set up your fuel system? Did you mod a returnless rail or rig the.mark rail? Could be a regulator sensor or possibly maf. Without some more info on the build it's kinda hard to get a start point.
My friend! I saw your video carefully and read your notes on facebook and I noticed several pending details on my mustang, change the polarity of the cables that go to the ignition coils, change the MAF sensor, buy for the lincoln mark viii, and change The ECU that came with the car (automatic) for an ECU of a manual gt mustang, and now my mustang runs perfect, it goes on in the morning very well and now if I feel the power of 4.6 4V. Thank you very much for your video and your notes, they served me a lot! A thousand times thanks my friend !!
If you are doing as I did and use all the GT equipment then you dont need them. I used the GT harness which has no connections for the knock sensors. The only thing I used from the Mark was the engine and throttle cable. All the wiring is stock GT. Just modified.
You just line it up and tap it in with a ballpeen or use a socket and hammer. Automatics don't have them so if you get one remember to install it if your using a manual transmission.
Thats a negative. 4v parts only. The ports are different etc. You would need manifolds or headers for a cobra and or mach 1. If you get a mark viii motor the manifolds won't work as well. The mark has specific to them manifolds with a converter connected directly to it.
I have a 2000 gt mustang. I put a motor from a 98 lincoln mark 32 valve and I can't find the knock sensor plug on the mustang harness. Is there a way I could talk to you about it?
+Rupe Pavon the 2v engine does not a have a knock sensor. It is not needed to run the engine. I use my GT harness and ECM. It was tuned by VMP Tuning. All are welcome to visit warhorse mustang club (open group) on Facebook. There you can post pictures and questions. I try to answer in a decent time frame.
+tim walk the harness on the 97 is a bit different then the new edge. With the 97 I would set up the car with 97 cobra feel. I'm thinking the 2v and 4v at those years closely match in harnesses. Im not to familiar with those years. I do know that the 4v has knock sensors and the 2v does not, so that harness part would not be there.
of course, but here is the deal with that. with getting C heads, (which you can get from a 99-02 continental cheap from a yard.) the issue you that you will have is the mustang parts you will need to get. you will need either a 99-01 cobra intake, or the 03-04 mach intake. I would go mach so you can use a shaker. but with that aside, you will need the throttle cable, which in it own will be difficult. it has been discontinue and Is hard/expensive to get. now I'm not sure if you have seen or read my writeup (if haven't you really need to.) but if you haven't there is a list of parts in there as well. also with the mark motor swap, getting a passenger side valve cover will be very benifitial with overall function and install.
It should fit. I would look at a Marauder. See how its setup. I dont see why you couldnt. The tuning may be differ. But as far as fitment yes it will go in.
josue vasquez yes you can get them for Mach 1. there are some places that may have the wrong hose listed, check with the write-up for the actual numbers.
did you have to mod the fire wall? im doing a mark swap with a 93 mark motor and the intake is smacking the fire wall... should I use the same intake as you and if so will there be any issues in fightment?
With a new edge the second generation Mark VIII intake should be used. Unless you can get a complete 96-98 cobra intake. Either way you will need it complete with TB cable and cruise cables. You will need the imrc from the sec gen as well.
+TenchFries At the time I did this the cobra intake was outrageous. I also wanted to kept it Lincoln. I port matched the intake. If deciding on the Cobra intake then I would also shoot for the intake cams to utilize it. With my project I have since removed the B heads. I ported a set of C heads and swapped to a Mach 1 setup.
I see, Like a bunch of others I was considering this swap once it warms up again. Where do you think I can get the intake cams for cheaper? I suppose my best bet would be a wrecked cobra or a stuck motor. I would just keep the mark intake but I love the look and extra power of the cobra toooooo much. Oh and that Mach 1 set up sounds beyond badass
The 98 Mark LSC was rated 290 with a highly restrictive exhaust. The intake cams is where the difference is. And mild at that. The intake cams I would keep an ear to the forums. I see them for sale time to time.
TBH the stock mark viii TB is fine. When I went turbo I upped to a Dual 65mm but for NA the stock TB is more than enough. Hope that helps. Congratulations on the start of the swap journey.
I built the engine bottom up. I used DSS Racing -10cc pistons and I beam rods. This lowered compression to roughly 9.4:1 ish. I built it in mind for boost down the road. The stock crank and handle any amount of NA power pretty much. I ran that setup for 8yrs. No complaints.
The Mark VIII production was stopped in 1998. There is nothing after that. There is the Lincoln Continental that has a DOHC as well but the block is cast for fwd and will not work for rwd applications. The only things, worth taking from one is the intake spacers and heads, those year Continentals had C heads and the intake spacers were c head to b intake. That way you can use a b head intake if you wanted to update from b heads.
@@NomadGT Thanks for the reply, I ended up finding out what was going on, maf that was extended was wired backwards and the intake manifold was leaking pretty bad. Did you use your mark8 manifold or cobra?
@ninjamike04 i mostly answer but to their inbox. it's easier to get at me on, the mustang modders form site. I'm a moderator there. i don't always see comments in here.
No.. check the links in the description. The physical write up goes over the wiring modifications as well as some part numbers that can be beneficial for you swap.
Well my swap was into a mustang so I used my GT harness. The TC I would think is somewhat the same. Depending on year it maybe a separate iat and maf. So 2002 and later used a 6pin MAF and prior to that the MAF was a 4 pin maf and the iat was separate.
Hey I got a quick question I'd love you to answer I'm going to do a swap on my v6 mustang I'm thinking of doing this motor over the stock sohc 4.6 I know they will both be difficult but do you think it would be worth it ? And I'm able to get a full 98 mark donor car running strong for 500 would you try the swap? Also No Imn ot just gunna go buy a gt like everyone else I wanna build my car hints starting with a v6 auto not just buy it
well I for one love my 4v, but not sugar coating it, because it can cost more. as far as your v6 the easiest route, is you'll need a GT engine harness as well as ecm. I'm not super familiar with a v6 swap but lookup Warhorse Mustang Club on Facebook. look for Jason, he did a mark viii v6 swap. he maybe able to help you alot more with that subject.
+32vNomad hey thanks so much man that might actually help a lot I'm gonna shoot him a message first thing in the morning and just one more thing if you don't mind do you know if the k member is the same on the v6 and gt or are they slightly different ? I've heard both just haven't got a 100 percent answer just a bunch of possiblys
The engine that went in is an all aluminum engine that's a teskid block as well. You can put on 4v heads on your 2v but there are many other mods as well you would need to do as well. But yes I removed the Cast Iron 2v and replaced it with a teskid blocked 4v.
hey man I plan on doing this swap to my 94 tbird will I need to change my computer and in car harness and everything? like what all in wiring and ecm will I need to change in it mines got the 2v 4.6 all the same as a 96 mustang gt
I would look into the 93-94 mark for a donor. I believe the t bird and mark share similar platforms. you possibly would be able to get by with an entire engine harness swap. but I would think that you could use the tbird harness, and modify the needed pigtails. the ECM maybe the hook, you would need someone that can program that version of ecm
+Chase lames with the Tbird it shouldn't be to difficult. I would think the same mods to the tbird harness would need to be done. like I said I would look into a 93-96 mark engine. the intake flows better. and should fit in your compartment. I would use a rpm switch to run the IMRCs. the big thing will be getting ur ecm tuned. but like I said I think the mark and tbird share the same platform and some under hood locations.
+32vNomad I have a mark 8 donor car at my work that has a motor ecm and harness would that be all i need to swap it over or do I need more stuff then just that ?
+Chase lames well you would need the ecm harness as well I would believe. the DOHC motor has things that the SOHC does not, ie knock sensors, IMRC, etc. I would check for pin outs etc, for the differences between the to.
same plug in.play style but the engine is taller. I've seem people use shims on the k member to lower the engine in the bay. the issue with a 5.4 is the intake there isn't one that is a bang for buck. there are adapters to make the 4.6 intake work. there is also strids with using the coyote intake as well.
+32vNomad Thanks for the Replay i most likely going to be using lower navi intake with custon upper sheet metal 1/2 inch k member spacers with cobra pacesetter long tube's
+32vNomad. hello just trying to find some info i am about to do a 4v swap of a navigator heads on my 2004 mustang gt really need some help you sound like a well knowledge individual just trying to know everthing i need. I would really appreciate your help
+Jony Heredia using 5.4 4v heads are not a good choice on a 4.6. the engine cannot fill it's cylinders fast enough to take advantage of the heads. you can find early c heads on a 2000 and up 4v continental pretty cheap. but 5.4 heads on a 4.6 is not recommended.
+32vNomad thanks for the reply so 2000 Continental heads but I heard you can use those heads ford v8 5.4 4v but 2000 Continental sounds pretty good I'll look for those heads instead
Excellent info. I have done the same swap back in 2016 and you mentioned a few things that I had not thought of doing. Thanks for making and sharing this!
Ford should have put the 4v in the mustang GT
+Mike Gardner they did 2011 but now people swap out 4.62v for coyote on older mustangs
It's still difficult to find a coyote with all its electronics for a good price on a small budget. The mark is still a good alternative to swap. And to spend the amount on a stock coyote, is still a head scratcher imo. I get asked why didn't I go with the Cobra intake. And simply put, cost. But also longevity. I planned on a different setup later on. And new spending the cost for that intake at the time was just not feasible. On the up note, I like the conversation peice, the intrigued look on folks faces at shows. I enjoy that.
@@agencyheadquartersdc4568 Or just a mach 1 and save your safe the problems . The price has come down on some of them with high miles but everything you need is there to start with.... In the long run a rebuild could cost less.... With the Mach you get bigger brakes a 3.55 rear..
GREAT points, getting closer
Great vid. I have a 1996 4.6 2v non PI want to switch to 4v and PI intake, Not having any luck finding 4v cylinder heads for 1996 that is a 2v now, kits. Body and interior are cherry, zero rust, 49k miles, motor is my only concern project.
on a pre PI car you will need heads as well to use the intake. I would use late 02-04 for parts. the compression will be 10-11:1 on the non PI engine. it's all plug and play really. if cams are in the budget I would go with something mid to high and throw gears at it.
you can always mark swap, or cobra 96-98. loose weight of the front.
Motor runs good just wanting to juice it up a bit. Thinking of check some wreck lots, try find low miles but don't matter, just not sure how to tell looking before I remove, that it's PI heads.Changing to 4V heads seems like more effort than I want.
+Mark Jakims
here is a photo comparison of the pi and non PI head.

Ford part number 8005 radiator for GT, DOHC , and DOHC s/c. so... just because an aftermarket sells you a all aluminum radiator does not mean it was when it left the factory.
Well all my wiring is almost installed. Im trying to change the heater core while the dash is still out but not having much luck pulling the old one out. Im also having an issue with the 99 cobra tail light wires. Since mine was a v6, i have the all red tail lights which have a 4 wire plug. The cobra harness has a 5 wire. Bot sure how to make that all work. Part of the reason i changed the body harness is because i was told it had to be changed. The other reason is because i had a bunch of extra wiring that i wanted to get rid of from installing the mach 460 sterio. Now that all of my wiring has the mach 460 wiring its alot cleaner looking of an install. I even changed the door harnesses for the mach 460. Just trying to do this the correct way. Any cut wires or plugs i found were cut from my old harnesses and soldered onto the new wiring along with heat shrink tubing. Anyway suggestions on the tail light dilemma?
i just finished this swap the mach1 throttle cable works with the 97-98 mark 8 intake.
The Cobras definitely have different radiators, I have one in my car. The Cobras have aluminum tanks and three cores.

Ford part number 8005 radiator for GT, DOHC , and DOHC s/c. so... just because an aftermarket sells you a all aluminum radiator does not mean it was when it left the factory
I actually swapped out all of the harnesses for 99 cobra along with 99 cobra ecu and 99 cobra gauges which came from the same car.
Im concidering using the mark intake as it seems alot of the 99 cobra engine harness plugs are almost in the exact same place as the mark viii. And i will be able to use the 99 cobra fuel rail. And keep the fuel rail pressure sensor in the same place.
This is some what correct but the rail is not plug and play. It has to be modded. The tabs have to be removed and the mark viii tabs have to be mounted. You may still run into PATS issues because the BCM body control module. Not a 100% but you may run into issues. That's one thing when doing a swap in that caliber, is you have to swap everything. Just remember you will still want it tuned because the engine though a 4v is different from the 99-01 Cobra 4v.
32vNomad my car used to be a v6 so thats why im doing all of the swapping. i used what i did because i was told to make a mark motor work with as little modding as possible i had to use all 99 cobra electronics. Where is the BCM? I was told only the gauges, ecu, and key make up the PATS.
Currently I have a 3650. If and maybe when, im going to look into a tko 600. But im sticking with the 5 spd though
The transmission from the Mark its the same one like the mustang GT
That I cannot answer definitely but if it's a aode then yes but tail shaft may be different, etc. Mine is a manual so for me, a pilot bearing had to be added to the crank.
I'm in the middle of a 4v swap from a 97 cobra into my 03 gt and have ran into a couple of issues primarily the fuel rail, it seems you are the only guy that has posted a very informative write up about it, it has helped me out a lot thus far but if any way possible can you email me so I can ask you a couple of questions that would be awesome. thanks in advance!
+Bobby Romero the fuel rail used was from a cobra/Mach 1. The tabs from both we removed, and the mount tabs from the mark viii were put on. Zip ties and JB weld. The setup works well, I haven't had any issues. I would suggest taking a look at Warhorse Mustang Club on Facebook. My write-up is on there alone with photos of the rail. I can also answer questions faster
+32vNomad I have tried to look up the page before but since I don't have a Facebook account I can't view the full page, I ordered a fuel rail from an 03 cobra and did the same thing but didn't account for the frps and the upper intake cover is hitting it not allowing it to seat. I don't know what other fuel rail I could use with the return less set up in my 03?
+Bobby Romero message me your email, to my page and I'll send you a copy
+Bobby Romero drive.google.com/file/d/0B320LOUTsb_eVXlUb0dkS01ZZTA/view?usp=drivesdk
+32vNomad is there anyway you can email me? bobby.romero23@gmail.com so I can send you a picture of my issue. My cobra intake manifold is hitting the frp sensor on the 03 cobra fuel rail. I don't know of any other way of using return less besides the fuel rails you stated in the write up but all of them have the frp sensor in the same position.
Very nice write up! Was wondering what internals these engines had. Was there a difference in hp from Mark 8 to Mach 1? Also did you say you switched polarity on every coil pack? Thanks for the write up and any help.
I did a similar swap on my 99 p71 i had a full donor marauder and that 4v is no joke
I like the 4v. The potential is great. I've since this video have swapped to a c head config. (Didnt seem to change power much) I have also turbocharged it. 8lbs with a single 66mm mp made 510hp 532tq. The MP turbo was journal bearing. Got a 67mm cbb now. Hopefully this spring I'll get back on the rollers. Had a oil line failure my last show, caused some smeared mains. I post most vids on Instagram @32vnomad got a short roller vid up.
@@NomadGT are you in the palm beach area?
Excellent video, but one issue about what you said. The early 4.6l engines have a different transmission bolt pattern than later models.
actually no the only difference is the fwd Continental dohc which the block has no provision for the starter placement on the rwd. And to add that the block you see in this video is that of a 1993 dohc intech. which has a 2002 tr3650 behind it. bolt patterns are all same for rwd 4.6l.
wow thank you for this vid! i have 4.62v 2003 GT my goal with it is 400 hp. god knows i would love a 32v but i think 10p of boost on a turbo might be the cheapest route
I have a 2v with a vortech and its making 400whp, a reliable option
Nice sounds like something I'd like
Have you had a plug blow out yet? Hehe. Happened to me in my 97 Mark VIII. Had to use that TimeSert thread insert kit to fix it.
Negative. Currently run early C heads boosted. Zero issues with plugs.
Awesome job, looks good. The only thing bothering me is the CAI in a HOT engine bay, kinda defeats the purpose, sucking in all that hot air
daveyhouse yeah me to, there was more of a push but that was 4yrs ago. I in process of part collection for a refresh and C head exchange. the AF is from a k&n kit but the guy I got it from didn't have the surround. never really bothered. but yes I have it on my list to do. 😊
Yes reflection livingsin I have a pix of rally for the boondocks
+Jordan M pm sent
+32vNomad how did you use the coolant temp sensor and the cylinder head sensor on the 4v swap I no the 2v has them bout but on the 2v the cylinder head temp sensor goes into the driverside cylinder head under the intake and the 4v goes on the coolant hoses by the alternator
+modded Crown Victoria 2009 p71 flex fuel the mustang 4.6l doesn't have the head sensor. The crossover tube for the mark engine has two outputs for two sensors one I believe is for the gauge the other one I believe it's for the ECM you can use the passenger side hole for the coolant sensor. Using a Mach 1 or Cobra setup (C head) the crossover tube has the sensor on the drivers side. The coolant connection will have to be lengthened. I have however thought about wiring a separate gauge for the head temp.
how much more work would it be to do a 5.4 4V Navi swap? they seem to be a little more common and sometimes cheaper as well even compared to a Mark motor
Im gonna be doing this same motor, however my motor will have the 98 cobra intake manifold. Im going from a v6 to the mark vIII motor. Im gonna assume once I change all my harness its just a matter of changing the parts you mentioned for the mark motor to fit the Mustang and it would be plug and play f4im there?
If your doing a new edge the fuel rail would be done in the same manner. Unless you want to redo the entire fuel system. I would suggest modding the returnless mach/cobra to fit the 98 intake.
I'm very much interested in this I have a v6 I would very much like to swap a 32-valve into
Same would apply. Depending on the year will be dependent on the part list. If you in a new edge then you'll need some things I'm not sure if the v6 has the hydro boost braking but you'll need that. And all gt lines. You need GT wiring as well, it would be the cheapest. Idea in your case maybe a mach 1 or cobra pallet with engine and ecm harness. The car would need a tune regardless to deactivate PATS but it shouldn't be an issue.
Looks sweet! Blew my head gasket and need a new motor, want to do the same on my 03, how much am I looking at to do this?
well price may vary. Mark engines are decently priced, most u pulls are scrap priced if you pull it. but then you have to think of your build and what you want. like if your going to forge the bottom end, etc. it can get pricey. it's all about where you get the parts and what you end goal is.
Great job!.. I have in mind, an equal project but I think to use an intake jet Cobra racing Ford, how many horses you won with the modification?
Nice engine
Thank you
Looks good dude
hello, first I want to say thanks for the video it's really usefull, second, I know this video is a little old but I still want to try to reach you and ask you: what do you mean by reversing te cables? thanks in advance.
+mike broswood well first thank you. To answer your question if you talking about the COP's then yes you well need to reverse the polarity of the connector. As the 2v wiring is opposite. If you are asking About the alternator that is also something you need to reverse when using the Mark setup. If you are using a 99/01 or Mach 1 setup the u need just the 4v pigtail and keep the wires the same. In the description there is a link to download the write up. As well as others. There is also another vid I have that answers some other questions. Hope this helps.
dude thats sweet im doing it but from a v6 to a mark vii yeah i know i have to get the cross member an upgrade my front end but im getting the whole car for 600 jest a bad tranny but i bought a t45 one fro the swap
This looks great!
I have a 2002 3.8L, im wanting to buy a wrecked 4.6 of a similar year to use as a donor car and swap everything over. Im concerned about the vaccum lines, should it all be pretty standard to swap as long as I have the donor car there? Any tips on it? Thank you.
+Austyn Oconnor the vacuum lines are very simple. You can also check with NPD they have the vac stickers and under hood info. Now are you looking to do a 4.6 sohc or put in a dohc.
Trying to get one of these for my p71
I would look into the Marauder. That should be a straight forward swap as well.
Have you heard of putting one in a 98 mustang that motor using the coil pack and plug wires
Yes as the mark VIII is originally like that with the setup, there is less wire modifications involved.
@@NomadGT thanks I been having a miss when giving throttle I'm guessing coil pack or wire I don't put mass air and iac on it
Please be sure to like and share this video with other communities abroad.
Ok thanks. that's what I was looking at doin
32vNomad. love your video and what you did with your car.
My question is ive got a motor out of a 2004 lincoln aviator. Will it plug and play like yours did out of the mark viii
+Cleve Wilks thank you. As far as the aviator engine it will somewhat. The intake is the factor for it. If you use the engine with a mach intake/rail/alt/etc it would be an easier swap. You would need an oil pan as well.
+Cleve Wilks www.mach1registry.org/forums/showthread.php?t=40219 info about what make the intake work
what about injector 1 wiring doesn't it have its own pig tail seprate from the engine harness
GT harness is a bit differ but no it is into the main bulk. But nothing need to be modded for the injectors. Unless using ev6 then you can change connectors or use adaptors.
Hey bro I love vid. I got a 00 gt I just did a 4v swap from a 2001 cobra and I was just wondering to extend the coil wires did you splices them and used extra wire. Then sottered and heat shrink them
when doing the coil setup, you should wire one coil complete at a time. I start at the coil side and work back to the harness. use good solder, and heat shrink tubing. take your time.
Seems like a lot of trouble for 40 horse power. Maybe if you've got a blown motor already needing replaced. Could have the 2v at 4v power with bolt ons and 400+ with FI. 4v can't really handle much more power than the 2 in stock form anyway so no real benefit between the two. I do love the bigger motor though, how can you not.
It's called power potential. Stock for stock 4v better choice, even a forged bottom end upgrade between the two aside 4v a better choice. Boost the 4v and 2v and still the better choice. But to each his own.
Heres a dumb ? Were you able to get the instrument cluster ti work with the 4v swap. I have a 2000 gt 2v and was thinking about doing the 4v swap
Never had to mess with anything inside for the 4v swap. You use all the same electronics as your gt.
@rob johnson in my video there is a link to a write up that goes with this. It will help you on your way. I can also be found on warhorse mustang club on Facebook as well as @32vnomad on Instagram.
But no you don't need to mess with anything in car.
so all I have to change is the radiator hoses and everything else bolts on?
IIRC, don't 99+ GT's have a returnless style fuel system? How did you adapt the return style fuel rails from the mark to the returnless system on the GT? What about the IMRC's?
The fuel system is still returnless. I used at mach/cobra fuel rail. I used the mount tabs from the mark rail to use the rail with the mark intake. Cut the tabs from the mach rail and remounted the mark viii tabs. I have ev6 24lb injectors from a mach as well. I'm going to edit the description to include a link to my Facebook version of my write up. There are photos as well.
Im in the middle of a horrible swap and I'm curious of what fuel rails you are running I have a 93 Lincoln Mark 8 long block with a 98 Lincoln Mark 8 intake I'm having feel real issues.. hooking up to the factory fuel lines
I have a check battery light in my p71 swapped crown Vic. But I changed the pigtail. You said switched the wiring, there's only green (ground), yellow (power), and white (dummy wire). What do you mean switch the wiring?
The pigtail has a signal wire and power wire and neutral I believe. If you are using a mark viii engine with its stock alternator. You'll notice that the plug, plugs in reverse. So you need to switch the wires at the pigtail in reverse.
Nice job! Please help me. I did the same swap on a 96 gt. I can't get it to crank and it leads me to believe its a ground wire issue. What grounds did you hook up and how did you fix your alternator. I have the pigtail for the 4v but it has three wires and my 2v has only two wires
awesome video man. just wanted to ask you one thing just to make sure i heard you correctly. you said you used the stock gt wire harness, but swapped all the sensors that were different from the 2v to the 4v, correct? any way you could be specific on which sensors were different? do you have any issues with a check engine light doing that or anything on the swap? and sorry last question, did you have to change anything with the computer?
the sensors were just swapped from my 02. the 93 Mark sensors some were different connections. I used all my GT sensors with the exception of the fuel and that was from a cobra.
the computer used is my GT computer, it will run the engine as is but not idea. it will need to be tuned.
Nice video! Im in the process of doing an aviator swap on my 99 gt. Did you have any issues with high idle? I dont appear to have any vacuum leaks, however it will run an appropriate idle with the TPS unplugged. TIA
Check your resistance of the TPS sensor. It could be your issue. Are you using the aviator intake or did you use a cobra/Mach intake?
Im running a mach one intake@@NomadGT
Replace it with the Mach 1 TPS sensor. Also you should use the Mach 1 iac valve as well. But get a vacuum gauge on it and make sure it's not leaking
Will do, stay tuned haha. Thanks!@@NomadGT
Why not just put the Cobra intake on it?
Hey I’m purchasing a mark engine this weekend to do the swap.
If you keeping the Mark VIII (2nd gen) intake, make sure to get the throttle cable and cruise if you want that as well. While your looking for parts get a mach 1 valve cover set.
32vNomad I can’t use the valve covers that are on the 98 mark motor? Also what year cobra oil pick up. How does the tune work? Do I send out my Ecm? I’m confused a bit.
Well I would get a new pump from ford racing. It comes with a new pickup. As far as the valve cover is concerned. The heater hoses in the rear on the 99-04 GT are quick connect hoses. The hoses can be reused with a mach valve cover because the breather is in the front. The mark cover has the breather in the rear making the quick connect for the larger line unusable. Also the engine has more of a rub point. Its best to get the covers when getting parts. The ecm needs a tune from a tuner. You will need to have a sct tuner and a shop that can either email or dyno tune.
32vNomad can I use a computer from an 01 cobra and just plug and play? Instead of getting my computer tuned? Also what year oil pump and pick up tube?
The ecm is not plug and play, the cobra has different pinouts and would need to be addressed. But also a tune would still be needed for the security to be disabled. With the oil pump just get a hi flow melling or a ford racing oil pump. You can get one form lethal or american muscle.
Hello I Am Working On A Similar Project With A 98 Mustang GT
But I Can't Figure Out What To Do With The 2 Butterfly Throttles On The Back Of The Intake
I Have The Box With The Cables For It But Trying To Figure Out How It All Goes Together
Please Help 🥺🥺🥺🥺🥺
What intake are you speaking of? Are you speaking on the 2v intake or the IMRC on the 4v? If its the ladder I deleted the butterflies and ran it. Since the 2v doesn't control them any way.
@@NomadGT The 4v I Have A 98 Mark 8 Engine Going Into A 98 Mustang GT
I Heard Somewhere That You Zip Tie
The Butterfly Throttles Open
Didn't Know How True That Is
Or Is There Some Type Of Kit I Have To Buy
I'll Appreciate Any Advise That You Could Give Me
Thanks
I removed the butterflies on mine but left the rod. It was fine.
@@NomadGT Ok I'll Go That Route
You Did A Really Nice Job On Your Mustang
Thanks Again 👍👍👍👍
Thanks man, and any time
Those 4.6 mark Vlll engines are Huge!!! They look like big blocks lol.. well compared to an LS engine. Btw you can check out my Lincoln mark Vlll on my UA-cam
Can you use a 99/01 Cobra or 03/04 Mach 1 engine harness for the coil on plugs?
Yes you can. But if you have a GT 99-04 will work. Plus it's easier to find harnesses in the yards than trying to find a good 4v harness
Hey I realize this is from years ago,but hopefully you will still see this. My 2002 GT engine (4.6 2v) has a rod knock and we are trying to weigh our options as to what we are gonna do. How much do you think it would cost to swap in a 4v like yours? I have a buddy that can do it for 50/hour so I'm just trying to figure out if I should upgrade to a 4v or find a refurbished 2v to dump in the car. Any insight on the subject is greatly appreciated! Thanks
Well the cost will be the engine and tuning if you use the GT electronics. You can find mark viii engines for a good price. The issues with cost is what your end goal is. Is it just, a daily or something you wanna put power in. With the 4v comes a higher cost when adding power but not much. Being that I did all my own work in this swap and build (except machining), my cost was low.
What are you looking to do moving forward?
@@NomadGT I've actually fully decided to go with the Mark VIII swap. I guess some questions I have right now are. I found a post on CL for a complete 4v swap with a bunch of listed parts. I'm not buying everything he has listed. But he does have a Mark VIII motor with 126k for $500 and a 96 Cobra Intake manifold w/imrc plates and throttle body for $350. Is that a good deal?
If that intake comes with the throttle cable and brackets then yes. Some try to sell just the intake for 350. The engine sounds like its priced right. You can find me on Instagram be sure to follow the links to my write up. It should help alot.
@@NomadGT Alright thanks. I'm reading over your facebook write up right now. What would be the best way to contact you for questions if you don't mind me asking? I really appreciate your help!
Right through that Facebook website the warhorse Mustang site is mine
ok thank you. on the hoses will the gt ones work on a 01 cobra?
josue vasquez if you have a cobra I would not purchase GT hoses. Mach 1 and the Cobra share the hoses. the hoses on this swap are Mach 1/Cobra. I at first a 2v but had to cut it apart to use the lower. I've switched to a Mach 1 lower since then.
Hey how is it going, I'm in the process of doing my swap but I have a couple of things that I'm not sure about, I have a 98 mark 8 and I'm using the 98 cobra intake manifold with matching cobra fuel rails. Do you know what exactly I need to do to convert the cobra fuel rails to return-less? I also have my 03 GT water pump, is a short water pump, will this fit here? and I have steeda UDP will those fit into this motor as well? if you coul contact me through email that would be fine as I dont always check on here. thank you
Quick question, I got a 95 f150 with a 4.9l 2wd 5speed and am swapping into a 95 4.6L 5 speed cobra engine. Where could I get a harness made for it to fit on the truck??
You could use a harness from a 4.6 truck. Basically ecm and engine harness. As far as making harnesses is concerned, I wouldn't know where to send you. All my harness modifications that were done I did. I would look to doing an engine and ecm harness swap, and modify the 96 harness as we would for the mustang. The fuel system maybe easier for you as I think you have return style setup.
What engine harness did you use? GT OR MARK HARNESS? Also did you use the existing Mark oil pan? Or did you have to swap oil pans? Do the Lincoln exhaust manifolds bolt up to the fact GT H pipe?
All parts you listed are mustang. The ecm is GT. In the link below the video is a download to my write up. Also you can find me on FB under warhorse mustang club. I have it linked there as well.
@@NomadGT thank you for the info. I read the FB information page on this write up. Couldn't find anything about the stock Mark exhaust manifolds. Will the stock mark 8 manifolds bolt to the factory GT h pipe. Thanks again
What did you end up doing with the knock sensors? Also where can i find the mark throttle cable and the mark cruise cable? I was gonna use the 98 cobra intake but it seems like i would have less wiring to do if it stuck with the mark intake. Im running the 99 cobra wiring front to rear including the engine harness.
The Mark cables you will have to find a donor (97-98) in a yard. I dont have cruise with my Mark setup. But with my C head change with Mach intake ill add back in cruise. I did not use knock sensors as I used the GT harness and ECM. It was a lot easier then messing with the Cobra wiring. The only way (for me) that I could see doing that is if I could get a donor car and swap dashes as well as modules, etc. If you have a GT set up its the easiest route to take. The car will run on the GT ECM, and can be dyno tuned.
You know I have to apologize, I was reading some of my past comments and realized you went a route (with wiring) that seemed a bit over. But here is a better answer. With you doing a complete wire swap, I'm assuming dash wiring as well the knock sensors you want are going to be from a 99 Cobra. See the technology changed a bit after 98 so I would suggest. That you do go with the C heads and 99 Cobra intake. But if budgeted you could run the 98 intake with the heads you have but you won't have the IMRC so remember you will have to delete them. Overall the best choice for your project would be getting a set of Mach heads and Intake or (continental heads 99-02 cheap from local yards) but still get a Mach intake.
Wiring wise im going from a v6 to the v8. However ill be doing 99 cobra wiring with 99-01 cobra ecu, gauges, and key for the pats. I should be good to go electrically yes?
I would think if you are doing the complete swap, you should be OK. I myself if doing all that then I'd do the dash swap. I know of a guy that had did a mark swap in his v6. he used gt wiring and ecm. not sure what all he did.
Oh okay I'm doing a 01 cobra swap so idk if it'll work
Josue Vasquez if you have a complete engine then no worries. things will plug up but you would need a tune.
I have 4.6 DOHC in 98 mustang out of Lincoln and my plug wires would a cobra wires work or do I need wires for a Lincoln but still have gt computer
Cobra plug wires will work I have a nice set of rear black Msd 8.5 mm like new and 2 new MSD cool packs 4-tower.but your cobra wires will work fine.written by Tom Hanson not Shelley.
Yes they are the same basically. 96 cobra and 96 Lincoln had the same wires, the 97&98 Lincoln went to COP. The cobra stayed wires on plug.
what about your nox sensors can you not use em also cuz your changing the pigtail on the altenator do u need a 4v stly altenator
The GT does not use knock sensors. By using the gr harness you eliminate their use. The alternators pigtail needs to be changed from the 2v harness. Also the alternators are different from mark to mach. You will need the correct one per intake setup.
This might be too late but I’m currently doing a swap and read your write up about the wiring. If you run the cobra harness on the engine do you only have to change the pcm or do you have to change something else ?
Yes. The Cobra engine harness pinouts are different. You would need the ecm harness as well that goes to the firewall to the ecm. It's just easier to mod the GT harness to work. Just take your time. I goto junk yards and pull factory harnesses to use when doing repairs or projects like the swap. Having oem harnesses is great because you can keep the same wire color and guages..
But to recap you would need the ecm as well from a Cobra along with the ecm and ecm harnesses.
So just the pcm and body harness only ?
Question? I have a 2000 Lincoln continental 32v intech alum 6 bolt mains. I want to swap to a 03-04 terminator setup that motor is. 4 bolt mains but I read they are the same motor just cast iron. I need your advice will it work finding a roller
the block you have is set up for FWD. the issue is going to be fit. the blower all the parts that bolt on the front of the engine as well as HP/TQ output to the transmission. from what I know the fwd block isn't usable in the rwd, so I would think the same would be true of the opposite. So in all I dont think a swap would work for you. I would look into more of a NA build with maybe spray. opon digging a little I wasn't able to find much info on that sort of swap.
Nice. I've a 1998 gt. I have in my garage a 1998 Mark viii complete engine. 121k on it. Would it be ok to just do a head-intake swap, or would you recommend a whole engine change? I'm aware of the teksid block and crank.
Well if the engine is complete then it's best to keep it that way. The pistons are different in your 2v and would lower compression. The swap is not to difficult. You would need some 98 cobra parts. Fuel rail mostly. You have to custom the egr to work with the mustang exhaust. Or have it turned off in a tune. You need the Mark throttle cable unless you use the cobra intake manifold.
Check out and post in mustangmodders.com im a mod in their forum. UA-cam doesnt notify me to well on comments.

What do you mean by switch the wires over? You said switch the wires over when you was talking about the alternator and the coils
the polarity of the coils are reversed. as well as the alt. so when you wire the coils make sure you reverse the wires.
32vNomad so if we were talking about a battery in this situation, Cut them and hook them up backwards?
looking at swapping a 93' Mark vIII into a 2000 gt. I noticed 93' mark doesn't have individual coil packs. can I still it?
To make it easier for yourself you should get yourself valve covers from a mach 1 or 99 and up cobra, to use cop. Check out my link for my write up. I have some parts you'll need. I myself started with a 93 mark engine.
I am swapping 2000 mustang gt engine with 2001 mustang cobra i have gt harness that does not fit the 2001 cobra injector pigtails any thoughts or suggestion is much appreciated
The injector pig tails are probably unscar connectors or ev6. You can either get ev1 to ev6 adaptors or get them from a junkyard as I did and swap them. Also I think the link for the write up is in the description it will help you further
What model car did you pulled the engine from??
Sry for the delay. The engine came from a 1993 Mark VIII. The intake and valve covers come from a 97 to 98 mark VIII.
I have a 98 mustang gt with blown motor will the 4 valve motor be a direct fit and plug and play and is there any specific parts that are required in order for it to work also my 98 gt is a 5 speed idk if that would mater or not
Well the 4v fits, as it's on the 98 cobra as well. Plug n play not so much. You could get all the parts from a Mark VIII but you would need to get some things from a Cobra. You would need the exhaust manifolds, heater core hoses, you need the mark throttle cable and cruise if you wanna keep that. You can use the GT ecm and wiring but you need a tune. And being a Mark VIII is auto you need to install a pilot bearing into the crankshaft. There is a bit more but look up warhorse mustang on Facebook. There is a write up that can help and it's easier for me to answer any questions.
Thank you friend how about a Romeo engines is there any special parts i have to have to swap the Windsor for the Romero engine
Sry for the delay I'm not receiving my notifications. But yes if you have a Windsor and are swapping to a mark then you will need a 6 bolt flywheel. If you get a cobra 4v they are 8 bolt. Other than that no. Not that I can think of.
Will a 94 mark VIII engine fit into a 03+ crown vic p71? If so what mods will need to be done ?
I'm not familiar with the crown vic, but I would say wiring will be the same as I did but for parts I would look at a marauder for a parts list. I would use a mark viii engine with 00 continental heads (tumble port) and a marauder intake. So the wiring you would mod from the crown vic. You would remake the coil harness wiring and get a set of 4v coils. A set of 97-98 mark covers or marauder covers. I would keep your crown vic lower coolant setup and run a 4v crossover delete. Headers I would look at marauders as well. I would do best to imitate that.
What fuel rail did you use and any modification need for the eails
for this intake setup the mark mount tabs were cut and mended to a 99-01 cobra/Mach one rail
@@NomadGT would any modifications be needed with a 99-01 intake and 99-01/mach rail?
No but those won't fit on b heads. You'll need c heads. Once you get those its just plug n play. The rail everything. Just as it would be on a 99/01 cobra or 03/04 mach 1. If you stick with the mark setup you need to mod the tabs for the rail. I used the tabs from the mark viii rail onto the mach/cobra rail
@@NomadGT okay cool, friend of mine has a spare set of C heads and also found a 04 Mach motor for $500 that had a knock so I should be set either way. Been wanting to do a 4V swap, would be more fun in the end and more potential than the 5.4 2V swap I was thinking of doing for simplicity and cost
5.4 4v lol snds good
I previously commented about my 2000 gt mustang and swapping the motor with a lincoln mark 8 motor. do I need the mustang injectors because I have the Lincoln injectors on and it doesn't want to crank I have fire and gas on the line. what do you think I need to do? the mechanics don't want to work in it because I put it in myself.
I don't have a Facebook but you can call me if you want to I need help.
+Rupe Pavon sry for the delay. I'm not getting notifications for some reason. As for your issue. Let me understand your car is cranking over and you have fuel and spark.? Questions for you. What harness did you use? Did you reverse the polarity of the coils? Are the injectors working?
What computer are u running? Gt or mark 8 ?
It's the GT ecm tuned by VMP tuning.
32v nomad who at vmp tuned it ?
+David Avalos I believe Justin.
+David Avalos both him and sct. There was an issue with my limiter being overridden but it ended up being on my end.
I have a 01 gt found a 01 cobra im nervous he said he has ecm and harness. Anything i should be lookn out for?
Did you have to upgrade fuel system or was gt fuel pump strong enough I did a 01 cobra swap into 00 gt run fine at idle or when revving but bogs and stuttering when driving a guy did a tune but I can't verify because I wasn't at shop I'm stock beside bassani x pipe jlt big cold air flow master and nos
There was no change for the pump. the GT and Mach 1 have the same pump. the car even without a tune did not have fuel issues other than injector mass meter mismatch.
OK thanks guess I'll start with my mass air meter that's the only thing I used from my gt
+Tyrell Woodberry the maf meter is for 19lbs injectors. you would need a tune for 24lbs injectors and a Mach maf. if possible I'd run 30lbs and have the Mach mass reconfigured for 30lbs
Hey my friend! How are you? I like your video, that engine looks really clean! I have a question for you, I am in a big problem that I can not solve, I am looking for help maybe you can help me, I have a 2000 mustang gt, originally it is automatic but install a 98 lincoln mark viii 4v engine and a manual transmission t45 of A mustang gt, the problem I have is that in cold start the engine is very difficult, it loads a lot of fuel to the degree of gas spitting through the exhaust, when I get it to start shaking and the smell of too strong a fuel in the mixture is strong! When I go out to handle it I can not feel the 290 horsepower that the engine has and when I reach a red light I have to be aware that it will not turn off because if it turns off it is difficult to turn it on again because it contains too much gas! What do you think is going on with my Mustang? Is it a sensor? Is it the automatic to manual conversion? I hope you can give me some advice, I really do not know what to do! Thanks for your time to read this message and I hope you can lend a hand to solve this problem! Thank you very much!!
+Luis Amaya well let's go back. Tell me about your swap? Did you swap pcm? Did you have it tuned? How did you do the fuel sys? If you on Facebook you can find me on warhorse mustang club. There you can post pictures and stuff. And will be easier to help you.
+Luis Amaya that's alittle nuts. Let me ask you how did you set up your fuel system? Did you mod a returnless rail or rig the.mark rail? Could be a regulator sensor or possibly maf. Without some more info on the build it's kinda hard to get a start point.
My friend! I saw your video carefully and read your notes on facebook and I noticed several pending details on my mustang, change the polarity of the cables that go to the ignition coils, change the MAF sensor, buy for the lincoln mark viii, and change The ECU that came with the car (automatic) for an ECU of a manual gt mustang, and now my mustang runs perfect, it goes on in the morning very well and now if I feel the power of 4.6 4V. Thank you very much for your video and your notes, they served me a lot! A thousand times thanks my friend !!
+Luis Amaya I'm glad to hear that. It would be cool to see it online. Check out warhorse mustang and post to the page.
Warhorse Mustang Club on Facebook
Small question what did you do about the knock sensors on the 4v mark 8
If you are doing as I did and use all the GT equipment then you dont need them. I used the GT harness which has no connections for the knock sensors. The only thing I used from the Mark was the engine and throttle cable. All the wiring is stock GT. Just modified.
How do you put a pilot bearing in the crank?
You just line it up and tap it in with a ballpeen or use a socket and hammer. Automatics don't have them so if you get one remember to install it if your using a manual transmission.
Would a pair of bbk shorty headers off my 02 gt fit in this engine swap
Thats a negative. 4v parts only. The ports are different etc. You would need manifolds or headers for a cobra and or mach 1. If you get a mark viii motor the manifolds won't work as well. The mark has specific to them manifolds with a converter connected directly to it.
I have a 2000 gt mustang. I put a motor from a 98 lincoln mark 32 valve and I can't find the knock sensor plug on the mustang harness. Is there a way I could talk to you about it?
+Rupe Pavon the 2v engine does not a have a knock sensor. It is not needed to run the engine. I use my GT harness and ECM. It was tuned by VMP Tuning. All are welcome to visit warhorse mustang club (open group) on Facebook. There you can post pictures and questions. I try to answer in a decent time frame.
what all did you have to do to your wiring harness to make this work I wonna do this to my 97
+tim walk the harness on the 97 is a bit different then the new edge. With the 97 I would set up the car with 97 cobra feel. I'm thinking the 2v and 4v at those years closely match in harnesses. Im not to familiar with those years. I do know that the 4v has knock sensors and the 2v does not, so that harness part would not be there.
Ok thanks
If i can find a set of c heads would yhose be worth swapping to the mark block?
of course, but here is the deal with that. with getting C heads, (which you can get from a 99-02 continental cheap from a yard.) the issue you that you will have is the mustang parts you will need to get. you will need either a 99-01 cobra intake, or the 03-04 mach intake. I would go mach so you can use a shaker. but with that aside, you will need the throttle cable, which in it own will be difficult. it has been discontinue and Is hard/expensive to get. now I'm not sure if you have seen or read my writeup (if haven't you really need to.) but if you haven't there is a list of parts in there as well. also with the mark motor swap, getting a passenger side valve cover will be very benifitial with overall function and install.
Whats the benefits to swap a 4v heads into a 2v heads, Beside that, does it make it sound different?
Well, for one better breathing than the 2v. Though a bit more expensive because of the heads. The engine has far more pwr potential.
And yes it sounds different
Will this fit in a 08 crown vic? I have the throttle body position sensor instead of the cable
It should fit. I would look at a Marauder. See how its setup. I dont see why you couldnt. The tuning may be differ. But as far as fitment yes it will go in.
For a 2003 v6 would it be the factory engine mounts for the 4v
You would use 4.6l mounts 2v/4v are the same. V6 I believe is different.
did you need to use the computer from the mark 8 or you kept the stock gt computer?
Used the GT computer. Just had a tune on it.
so what hoses do I need for the swap? all radiator I should get from Mach 1?
josue vasquez yes you can get them for Mach 1. there are some places that may have the wrong hose listed, check with the write-up for the actual numbers.
josue vasquez also you can check with mach1registry for extra parts
did you have to mod the fire wall? im doing a mark swap with a 93 mark motor and the intake is smacking the fire wall... should I use the same intake as you and if so will there be any issues in fightment?
With a new edge the second generation Mark VIII intake should be used. Unless you can get a complete 96-98 cobra intake. Either way you will need it complete with TB cable and cruise cables. You will need the imrc from the sec gen as well.
The write up link is in the description. It should be working. Has part numbers of this you will also need.
I see you kept the mark intake, would you recommend getting the 96-98 cobra intake instead?
+TenchFries At the time I did this the cobra intake was outrageous. I also wanted to kept it Lincoln. I port matched the intake. If deciding on the Cobra intake then I would also shoot for the intake cams to utilize it. With my project I have since removed the B heads. I ported a set of C heads and swapped to a Mach 1 setup.
I see, Like a bunch of others I was considering this swap once it warms up again. Where do you think I can get the intake cams for cheaper? I suppose my best bet would be a wrecked cobra or a stuck motor. I would just keep the mark intake but I love the look and extra power of the cobra toooooo much.
Oh and that Mach 1 set up sounds beyond badass
The 98 Mark LSC was rated 290 with a highly restrictive exhaust. The intake cams is where the difference is. And mild at that. The intake cams I would keep an ear to the forums. I see them for sale time to time.
I know this is an older video, but I just bought a Mark VIII engine. What throttle body did you use on the mark intake
TBH the stock mark viii TB is fine. When I went turbo I upped to a Dual 65mm but for NA the stock TB is more than enough. Hope that helps. Congratulations on the start of the swap journey.
@@NomadGT did you upgrade the internals? If so what pistons did you use? Rods? I found that I can get the 96-98 cobra forged crankshaft for about $400
I built the engine bottom up. I used DSS Racing -10cc pistons and I beam rods. This lowered compression to roughly 9.4:1 ish. I built it in mind for boost down the road. The stock crank and handle any amount of NA power pretty much. I ran that setup for 8yrs. No complaints.
Can you use a 2000 or 2001 mark 8 motor in this swap?
The Mark VIII production was stopped in 1998. There is nothing after that. There is the Lincoln Continental that has a DOHC as well but the block is cast for fwd and will not work for rwd applications. The only things, worth taking from one is the intake spacers and heads, those year Continentals had C heads and the intake spacers were c head to b intake. That way you can use a b head intake if you wanted to update from b heads.
Where is the body control modual?
Under the dash near the console I believe
Ive just finished this swap 98 cobra in 98 gt and my car won’t stay on what so ever
And when you did the swap what harness did you use? And what changes did you do or not do? Are you using all 98 GT equipment?
@@NomadGT Thanks for the reply, I ended up finding out what was going on, maf that was extended was wired backwards and the intake manifold was leaking pretty bad. Did you use your mark8 manifold or cobra?
Initially I used the Mark VIII but have since installed C heads and a mach 1 intake.
Hey bro how many temperature sensors do you use in the car cuz the Cobra has two on the crossover pipe right
1 sensor is used. Even my mach 1 crossover uses 1. I myself did a crossover delete using the ON3 delete kit.
I need your help man because I use a 2004 Mercury Marauder crossover and it has to left and right
Lincoln 4vs used 2 I believe but not needed. Is this going into a mustang or town car.
2004 Lincoln Town car
@ninjamike04 i mostly answer but to their inbox. it's easier to get at me on, the mustang modders form site. I'm a moderator there. i don't always see comments in here.
Do I need the mark viii engine harness? I have the 97 mk viii. Please let me know
No.. check the links in the description. The physical write up goes over the wiring modifications as well as some part numbers that can be beneficial for you swap.
Ok thanks for the reply man !!!!
very nice.
How did you do the coil on plug swap?
In my description these is a link to my write up. I go over it with some detail. I'm also gonna post a short or a shorter video going over it.
U have stock mass air flow sensor
At that time I used a MAF from a cobra with 24lbs injectors. Currently I'm using C heads mach intake. Boosted with 60lbs inj and a slot MAF
How do you convert it to 4 pin cuz the GT have 6 pin
mass air flow sensor
The outside wires are the IAC. But it's not needed really. You can get a MAF from a mach 1 it's a 6pin.
Thank you for your help
@Jonny Vargas no worries. If ya have any other questions feel free to ask em.
What harness do you replace because I didn't 4v swap on my Lincoln Town and I can't getting mass flow sensor codes and temperature sensor
Well my swap was into a mustang so I used my GT harness. The TC I would think is somewhat the same. Depending on year it maybe a separate iat and maf. So 2002 and later used a 6pin MAF and prior to that the MAF was a 4 pin maf and the iat was separate.
Yeah and I got the marauder mass 6 pin
You TC should have the same 6pin connector
Yes but I don't get why my car idle so high you think it's cuz the temperature sensor cuz he's not reading temperature on the cluster
You may have a vacuum leak
Hey I got a quick question I'd love you to answer I'm going to do a swap on my v6 mustang I'm thinking of doing this motor over the stock sohc 4.6 I know they will both be difficult but do you think it would be worth it ? And I'm able to get a full 98 mark donor car running strong for 500 would you try the swap? Also No Imn ot just gunna go buy a gt like everyone else I wanna build my car hints starting with a v6 auto not just buy it
well I for one love my 4v, but not sugar coating it, because it can cost more. as far as your v6 the easiest route, is you'll need a GT engine harness as well as ecm. I'm not super familiar with a v6 swap but lookup Warhorse Mustang Club on Facebook. look for Jason, he did a mark viii v6 swap. he maybe able to help you alot more with that subject.
+32vNomad hey thanks so much man that might actually help a lot I'm gonna shoot him a message first thing in the morning and just one more thing if you don't mind do you know if the k member is the same on the v6 and gt or are they slightly different ? I've heard both just haven't got a 100 percent answer just a bunch of possiblys
+Oliver Klozeoff I don't remember if he changed his or not. I don't think he did, But it was some time ago
transmission options? 5 speed?
You had to swap the whole engine right
The engine that went in is an all aluminum engine that's a teskid block as well. You can put on 4v heads on your 2v but there are many other mods as well you would need to do as well. But yes I removed the Cast Iron 2v and replaced it with a teskid blocked 4v.
what hoses did u need? or what else is different?
josue vasquez it's a copy of my write up. there are the part numbers you need. as well as the extra you should look for.
hey man I plan on doing this swap to my 94 tbird will I need to change my computer and in car harness and everything? like what all in wiring and ecm will I need to change in it mines got the 2v 4.6 all the same as a 96 mustang gt
I would look into the 93-94 mark for a donor. I believe the t bird and mark share similar platforms. you possibly would be able to get by with an entire engine harness swap. but I would think that you could use the tbird harness, and modify the needed pigtails. the ECM maybe the hook, you would need someone that can program that version of ecm
+32vNomad thank you I couldn't not find anyone who had any info on how to do this swap
+Chase lames with the Tbird it shouldn't be to difficult. I would think the same mods to the tbird harness would need to be done. like I said I would look into a 93-96 mark engine. the intake flows better. and should fit in your compartment. I would use a rpm switch to run the IMRCs. the big thing will be getting ur ecm tuned. but like I said I think the mark and tbird share the same platform and some under hood locations.
+32vNomad I have a mark 8 donor car at my work that has a motor ecm and harness would that be all i need to swap it over or do I need more stuff then just that ?
+Chase lames well you would need the ecm harness as well I would believe. the DOHC motor has things that the SOHC does not, ie knock sensors, IMRC, etc. I would check for pin outs etc, for the differences between the to.
what's the difference on the 5.4 dohc navi swap?
besides the size of the engine
same plug in.play style but the engine is taller. I've seem people use shims on the k member to lower the engine in the bay. the issue with a 5.4 is the intake there isn't one that is a bang for buck. there are adapters to make the 4.6 intake work. there is also strids with using the coyote intake as well.

Thanks for the Replay
i most likely going to be using lower navi intake with custon upper sheet metal
1/2 inch k member spacers with cobra pacesetter long tube's
+32vNomad. hello just trying to find some info i am about to do a 4v swap of a navigator heads on my 2004 mustang gt really need some help you sound like a well knowledge individual just trying to know everthing i need. I would really appreciate your help
+Jony Heredia using 5.4 4v heads are not a good choice on a 4.6. the engine cannot fill it's cylinders fast enough to take advantage of the heads. you can find early c heads on a 2000 and up 4v continental pretty cheap. but 5.4 heads on a 4.6 is not recommended.
+32vNomad thanks for the reply so 2000 Continental heads but I heard you can use those heads ford v8 5.4 4v but 2000 Continental sounds pretty good I'll look for those heads instead
