Ever considered an 8 speed 8hp50 box? Im doing a transaxle version and have designed an adaptor plate for it.

Hey man, I got an 88 Merc. How did it get to it? Take the door off?

The rims are from a Lincoln Town Car! They look fine on the Mercury though. These are great running and driving cars! Great find! The mileage should be visible, it's not digital.

You clean up the chrome with a SOS pad. My crown Vic had faded chrome and I cleaned all of it every where with sos pad and it shines like new

i daily my 92 town car and its been doing me really good so far

Beautiful car!

Those are Lincoln aluminum rims, but they still look good on the car.

The suspension may feel the way it does because it needs work somewhere. Or its actually ok, but it's just not to your liking. There's so much that can be done with that engine. Done right, it will still feel like it belongs in a luxury car, but have far more of it. You could possibly build it up to around 400hp without a supercharger, or at least 300+.

One of my dream ✨️ car 🛣

Keep the chrome you got a pretty good survivor!

Looks like a good sound project. 👍

waiting fore the next one Jay I will donate $100.00 when you make it run

Read the service manual

Great video. Thanks.

great job Jay cannot wait for the next episode contemplating to do the same I have a 89 convertible with a melted Marrelli distributor which some how transalated into an engine harness fire which originated in the fan relay near the radiator at the Jaguar shop. I love the perseverance

All you need is teeth for tdc on the 12 cylinders.The exhaust stroke is just a wasted spark.The timing advance map is programmed in the ECU the same for each cylinder.

Love your videos and I came across your channel a while ago and as an XJS owner myself would love to have the system myself. If you work out the bugs and get it all working you should totally develop it as a kit for us to buy. I think there's a couple others who are selling kits in Europe but no one is in the US/North America. Keep up the great work! Looking forward to seeing as things progress.

Comparatively= Chevy 350= 30" long 20" wide 22" tall LS1/LS6= 30" long 25" wide 29" tall

did you make that trigger wheel work ?

Thanks for this information, I have an engine, but don't know how to put it together. Six cylinder no problem, haha.

Just came across your channel and I've watched your last few videos. I've converted a couple of XJS is over the years in different ways including transmission/engine swaps. this build is turning out awesome! Love the videos on the planning and bumps one runs into throughout the process like this on these Jaguars. can't wait for your next videos. Have you considered buying exhaust components from simply performance? They sell different pieces and have an upgraded kit. I purchased a couple of their kits in recent years and love it! Not cheap though lol but you can buy just the rear half of their performance section etc. which would be perfect on your set up. Wouldn't cost that much since only purchasing the rear half. I suggest this because we decided to customize our exhaust initially but it was a pain in the butt and realized getting the sweet stainless parts from simply performance upgrade kit was way easier and looks gorgeous. I am very happy we went with the simply performance exhaust parts instead of full custom. We did have to go custom close to the engine as the simply performance kit follows the layout of the original system. Anyways can't wait to see more progress. oh and I have a 90 xjs and the problem with those years was the distributor cap and rotor button needed to be replaced every 30,000 miles or the Marelli ignition caused half the cylinders to ignite while not on the other half leading to a dumping fuel in the one bank into the cylinder/exhaust and then the Failing distributor cap/rotor button would then ignite erratically then igniting all the previously dumped fuel into the one bank/exhaust. It would then cause the one bank to get super hot and would often lead to engine failure. It actually happened to our 90 XJS and that's why we did an engine swap to it. They only used that ignition type for a few years because of this issue. in our example after the partial ignition failure event we had extremely low compression in that bank. It happened to us around 38,000 miles. maybe you're already aware of this phenomenon but it's very likely that's what happened to your cars engine as well. Too bad everyone didn't know this initially with these years Cars because many have been destroyed as a result. I think 1992 was the last year they put the Marelli ignition in the XJS. in my opinion they're quite reliable cars besides that main issue. Some of the older cars have a few other week points that if one is aware of and keep an ion Dan actually the factory original cars are quite reliable. Example I have a 1979 that's all original and still works well. Of course minus replacing rubber hoses and a few other rubber bits etc. but it's a shame on those Marelli ignition cars between 1989 and 1992. So many have been destroyed because of those stupid distributor cap/rotor button issues. is a cool set up though with the twin ignition coils etc. on those your cars. But since both banks have their own ignition if just one fails instead of both it's hard to tell when driving and then the failing bank burns up. Cheers from Canada!

Hello Jesse (sp) Thank you for recording your process on the 92 XJS; very helpful. I'm attempting to convert a 72 series 3 xke from carburation to EFI. I've purchased a 1988 xjs as a donor car for the needed parts which I understand will work as reference in a guide written by Roger Bywater at AJ6 Engineering in the UK. I'm finding that I'm not nearly a good enough gear head, in particular don't know enough about the electrical and electronics to potentially pull this off. I'm most concerned about getting all the needed wiring harnesses, relays, and assorted parts off of the xjs before I have a junker haul it away. (don't have the room in my garage to keep the xjs while completing the rest of the conversion. Any suggestions? Can I get you to move to So Cal for a while to help with this project? LOL

you did the right thing stay the course. you got first gear with low gear and great overdrive it will dance around the turbo 400 and get 20%better gas mileage

you are really plowing into some v12 swap development the complexity seems overwhelming I really appreciate your work I hope you succeed It seems The complexity comes from combining fuel , ignition and trans all at the same time. It would help if you could compartmentalize I am trying (plan stage)to use Mega-squirt v12 as well I have experience with ls XJS swaps and ms studio micro squirt(alfa spyder) But you are the pioneer in this arena no one has done what you are trying to do I salute you. Note there is a mechanic shop in Canada which has successfully swapped efi with ms2 and conventional ignition (distributor premarelli) into 1974 e-type 4spd etype was for sale on BYT did not meet the reserve

Nothing like a challenge. Keep it up, you'll get there. I feel your pain regarding the cold. It's been in the negatives here in Iowa. Burning lots of propane to heat the garage the one day a week I work on my Jag. Currently fighting a leaking tranny cooler.

do you have a basic tune working ?

do you have the mega-squirt installed

Why would you take out the turbo 400,its a better transmission

what springs did you use

this video has inaugurate lighting

Didn't the XJS have Lucas Electrics as OEM? I had a1972 Norton Commando with Lucas Electrics, and they were garbage. The coils kept going out on me, but I found a small Toyota coil that would fit and worked fine. I had to replace the horn switch also, and numerous little issues I had to troubleshoot often. Avoid Lucas at all costs.

Holy moly thank you sir you're doing god's work, this is gonna make my planning process way easier

Thank you for posting I’m about to start doing my 1989 Jag v12 and want to do what look like some of the same

Hey Jesse, great work. I also have a 92, but PO converted to a 5 spd manual.

good job!!

why didn't you use a ETB? The seup you have needs Cable throttle setup. you can control it with the computer if using a ETB. I used a ETB from a GM 3.5L V-6

Good luck Jay.. My son and I are doing the exact job, except we bought everything already made, programmed, harness, new injectors, full dis, everything.. I'm a licensed automotive technician for over 40 years and I was going your route, but no time.. you are much braver.. we do want to upgrade to the 4l60e tranny in the future... You just have to be very methodical.. I bought a large piece of paper, drew an outline of the car and started to draw in all the upgraded wiring, sound system, shaved door handle solenoids,, etc... may I suggest the same for future reference and diag...

You need to delete this and figure out how to make a video that you can even watch. You do seem to be a very nice guy.

Great work, your just as insane as my son and I... working on his 86 xjs restomod.. custom headers by VA Spiteri, custom intakes with snorkels, complete MFI kit from Mobeck,, all chromed metal or polished aluminum,, original TWR body kit,, complete shaved body,, custom interior,, and paint,, removed the aux fuel tank, and relocated the battery to the right inner fender pocket,, custom trnk,, twin 16" electric fans,, single adjustable fuel regulator,, all high pressure plastic fuel lines,, every nut and bolt are SS,,, 18x9" rims,, 265/45,,, custom steering wheel, etc,, etc.. These are great car's to modify, and incredibly beautiful.. My son wants to install a 4l60e also... He's killing me,, I'm glad you are doing it first lol,,, look's like your paying close attention to details and operations.. nice... Excited to see the inaugural run.. We have to keep these beauties on the road,, these young kids have no taste in real cars anymore...

Great work. You got to love the insanity that we have towards our jags.. you should see the insane amount work to my sons 86 XJS restomod.. how much programming or work does it take to work with the existing system or mega squirt.. what exactly does it need or inputs to make it work.. Keep up the brilliant work and videos..

Hey buddy. You should have called me before going through all that welding/fabricating work. All XJS cars pre 1992 should have the mounting points on the frame for the rear sway bars (I'm basing that on the 92 engine) but conversely, the 94 to 96 rear suspension trailing arms have the rear sway bar mounting bracket required for rear sway bars - that you fabricated - but the 94 to 96 cars don't have the body mounting bolts on the frame. Yeah. Jaguars are confusing and contradictory at best. But hey, now you know.

Thanks for taking a direct measurement! Much better than digging through forums trying to back-track to the original source 😁. This info also makes it seem like a 5-speed swap could drop 100 lbs off the car 😯

Hey thanks for posting, good content.

What year is you Mark viii? Makes a difference. 98 is a one year only part.

Very helpful for my project ideas- Thank you!

I own 2 XJS's and have 3 V12's on the floor in my garage for various projects. I am building a track car right now and am currently in engine rebuild mode so am reviewing what others are doing on UA-cam for tips, tricks and to not forget anything. I have NOS heads new valves and such, and am working on the intakes, porting out a bit, along with the new heads. I purchased enlarged throttle bodies from Simply Peformance in the UK as it seemed an easier way to go. Other mods will include a Getrag 265 5 speed conversion, stainless headers and exhaust, performance springs and adjustable shocks, complete suspension rebuild, etc. I am interested in finding out more about the megasquirt conversion you are doing so I can move away from Lucas. The guys at Mobeck in Norway have a custom system with computer, upgraded fuel injectors etc., but it is not cheap at around 5k. Great work on your project, I really enjoy seeing what others are coming up with regarding modifying these engines, especially peformance upgrades that don't clean out your bank account. Thanks.

Besides Bob's tool and use description over at Camp Chaos Chronicles, this is the best video on the operation and release of the easily breakable cam chain tensioner I've seen yet.

Some folks use a little silk string circling the perimeter along with the Hylomar or other anerobic sealant under the tappet block to help stop the typical oil seep seep from that area. Re-shimming after a valve job or change of cam is a real task taking the cam in and out as clearances are checked and adjusted... for which a shim kit /assortment is pretty much required.

I'm a little worried about the rear lip seal you showed in the video. What material and where did it come from/part number? I ask because the typical replacement unit does not look like that (seal color wise) and currently is only available , that I'm aware of, from Bently (which uses the same size).... it is a Yellow material, and is made of the correct high-speed FMK material. (That doesn't mean you didn't acquire an earlier OE seal but its pretty easy to just look up and find right shaft seal that will fit, but is rubber/nitrile and simply cannot cope with the shaft spinning at 6500+RPM. For example the Timken and SFK seals of that size that I've looked up just won't work. They specify a far lower shaft speed at that size, which corresponds to the material they're made out of.
