Engine Build × 4BT Cummins Discovery #11 [Land Rover Build]
Вставка
- Опубліковано 25 лис 2017
- Finally, the powertrain build is nearly complete! Big turbo & manifold, 5-speed HD trans & clutch, fuel & timing mods, new seals & lines & paint. All ready to meet a new set of Land Rover frame rails.
~ PART#11 in a project dubbed "Nanuuq" to swap out my lifted Land Rover Discovery 2's blown 4.0L V8 & boring ZF auto for a Cummins 4BT 3.9L turbo (Holset Super HX30W) diesel 4-cylinder engine (Bosch P7100 pump) with an NV4500 5-speed manual transmission. The AWD 4x4 will remain with the LT230 transfer case divorced behind it all, & plenty of Dodge 6BT parts too. Another big phase of my custom DIY build to create a do-just-about-anything off-road / overland rig. Did I mention it's a camper too?

NOTE: I started the engine before this & it was smoooooth. No smoke or blow-by, & great oil pressure 👍 Oh & that grungy alternator was just a placeholder for the high output Rover alt. Can't wait to hear it sing with all the new parts & mods!!!
Tinker get you a 12 valve or a 8.1 balancer and put on your 4bt smooths them out keeps em from being a rattle machine like they are with the stock pot metal balancer
What bail housing an tranny did you used????
@@matthewlarsen1573 That's an "Advance Adapters" bellhousing with a hybrid Dodge & Chevy 5-speed manual NV4500.
Seems pretty simple but still a lot of shit to put on and together
That's for sure! Simple as far as engines go, but still no shortage of work to be done fitting such a non-standard powerplant.
This build is going to be rad, super clean job!
Thanks!
i enjoy your detail work and you don't have all the fancy equipment this build is a real credit to and you mates.
Thanks! And I'll make sure to pass that on :)
Oddly satisfying to watch. Definitely going to check out the rest of your videos. I've always wanted a 4BT in my jeep excited to see your project.
Glad to hear they're interesting to watch, because that's always the battle with stuff like this... want to keep the audience awake haha!
Great! - One of the best diesel engines you can buy...!
Agreed! So simple & tough 💪
great engine build. perfect job
Thanks!
How satisfying, and it shows at the end. Great moment
I should've included a before shot with that final clip, such a big transformation.
beautiful work!!! so clean!!!
Thanks!
Hi everybody. Wonderful job congratulations 👍👏
Thanks :)
Thumbs up right back to you brother. Solid work.
Thanks!
man!! this is my dream biuld Disco2 cummins, manual transmission!!
Me too! Been a long time pondering on it.
The new engine is very beautiful
They do look quite good when they are clean :)
Well done, good job.
Thanks!
Great video
Thanks!
Nice! Nice! Also like the color.
It doesn't have the most inspiring name, Cummins Beige, but I quite like it too & I'm glad I stuck with it for the build.
Good work 👍👍👍
Excelentemente ejecutado. Felicidades por el viseo quedo super bueno
Gracias!
Thank you I learned a lot from you
Glad to hear it was useful! I wish I had a video like this when I started mine... so easy to lose track of how things went together haha
Congratulações👏
Great job...

Thanks! :)
Thank you very much for Sharing this video. I would love to be able to do something like this one day!
It was a fun build :)
I'm new to this channel what is this engine off from?
@@omarr6875 You can see where I found this in video #1 of the series. In my case a drilling pump. But normally the easiest source to find them are in "step vans" like what we use in the USA for delivering larger mail packages & bulk food. They can be found in all sorts of industrial, commercial, & power generation equipment... but that I'd less common.
Very pretty! 😀
Thanks man!
Very Nice job.
Thanks!
buen trabajo, i love this engine
Thanks!
Das sind super Motoren.
Agreed :)
Thank you sir
👍
I got one going in my 1992 S-10, 4x4. Modifying the pan now so I can keep the 4x4. Was going to rub😮
Nice! I miss my old ZR2 S10 project. Good choice, might need to modify mine too... it's pretty close at full flex.
Amazing
Thanks!
Nice!
Thanks :)
Nice video, just found your channel 👍
Thanks, looking forward to hearing it fire up again after all the mods & see how it pulls along the Land Rover.
Great video. And Pure Michigan I am a new sub.
Thanks & welcome :)
I'm dropping one in a 1969 IH Scout 800.
One of the best transplant options for those in my opinion!
Amazing Google job .from Pakistan
Thanks and welcome :)
Gerat video. I have question. In time 00:41, i think it is oli coolant cover? And is there normal gasket or did you use liquid one? I have to repair it on mine and i have no idea. Also i got hose from there going to turbo, do i have to put the Air out of the systém or it is not needed? Thank for help.
Nice.Profii✌✌
Thanks
Well I suppose I'll let you know how is goes, I have a black path billet cover I'm waiting to try out. One more thing, when I pull my p pump off will it affect the timing of the pump? Besides getting the engine back to tdc? Thank you for replying to my questions!
Best of luck! It can, have to be real careful to mark things & use the timing pins on the engine & pump to keep it straight. I have a video on the subject that could help ya.
I'll bring my Toyota over tomorrow so you can put that motor in for me. Thanks for doing it for free. Lol
If I fell into a pile of money it would be so fun to buy a dozen of them & just start handing out swaps 😎
Lt230 need an adapter to connect to the nv4500 ? And withstand the half-axes at the declared power 550tq ?
Here is what I made to adapt them together: ua-cam.com/video/XNwl8IDqSb8/v-deo.html And yes with upgrades the LT230 should hold, but we will see!
ok, that alternater needs a little more paint, you forget that ;)
Oh that was just a temporary alternator, as it now has a big shiny Rover alternator
Que características del turbo que tiene montado? Hx30w? Hx40w?
Nice job bro, hopefully when I do my 12v it goes as smoothly, gotta do the timing cover and tappet cover. Have you ever used billet tappet covers?
Thanks! I have not, but if I do I'll probably try out the kind that have the oil breathers built in. Some I've seen look beautiful!
Hi great video but quick question. What gear box did you mate it too?
Thanks, & that's a hybrid Chevy & Dodge NV4500 heavy duty 5-speed manual.
Very nice! Why did you knock out the welsh plug under the ex manifold and what did you put in there ? Looks like a yoke for hanging pictures on a gyproc wall?
The one there is my coolant heater (aka block heater), another plug in the rear is now my heater core supply, & the third is just a simple plug that I may drill+tap for additional gauge sensor.
Vey nice indeed can you tell me why you have removed some of the the core plugs and replaced them with (?) do you have plans for greater cooling ability?
Those are clamp-in aluminum freeze plugs. Primarily for giving me multiple places to tap in for heater-core hose fittings & temperature/fan sensors. Secondarily to prevent them possibly blowing out due to the much higher rpm & boost it will have now vs stock. Also makes for a handy place to drain/flush from & monitor the cooling passages.
Nice, I was lucky enough to compete in the camel trophy we used discos with the LR diesel it was a good combo, but I'm betting the 4BT will be better. I'm looking for one to put in my 79 F250 4x4
Oooo badass! I love the sound of those old Rover diesels. I think so too, future me will greatly appreciate all the work I'm putting into making it fit & doing it right. Best deals I've seen have been complete step-vans, if you've got the time for the tear down & cutting the aluminum shell up for scrap to recover the initial cost.
I want one! That looks like a beautiful little engine that I could use In a small pickup. (If I could ever find a tyranny for it.)
I feel you there! I've wanted one for years now, so glad I finally got into it :)
Be warned, the 4BT is pretty heavy (like 700 pounds - more than a big block gasoline V8) so if you put it in a small pickup like a Mazda B1600, an old Toyota Hi-Lux or a Datsun pickup, the nose will drag on the ground. You said small pickup so I figured that's what size you meant
and a TALL engine
Good vid, love the music
Thanks man, was a fun build & I'm looking forward to keeping the mods coming! More boost, more fuel, maybe experiment with running waste oils.
Tinker awesome man, can’t wait to see. I’ve experimented with the oils and all I can say is filter it down into a drum. 5 micron filter bags are awesome and let it settle. Depending on where you live at you can mix pretty heavy with your fuel. Most fuel filters are 25 microns so it’s pretty safe.
@@BolteBuilt I've always wanted to get into it, so that's good info. Everything I look into on it sure makes it sound like filtering & dealing with the cold is the name of the game.
Tinker yeah when you run it just run some type of fuel additive on occasion for piece of mind. It can be clean but black too. If you plan on using food based oils they not only need filtered but heated too I’ve seen. I stuck with used oil personally.
@@BolteBuilt Yeah no doubt about that, probably will run additives even with pump diesel, all depending on how cold a winter we get here.
that pump is just as big as the motor lol
It's like a little engine of its own too! Has it's own crankshaft, pistons, valves, etc
i was a little salty when you put that old grimy alternator on that clean AF 4bt, nice work though
It was only a placeholder! It now has my big Land Rover alternator mounted.
Cuantos HP tiene ese motor y que modelo de turbo le colocastes
Ohh cool
Thanks 😎
Great vid. My son and I want to build a 4 runner with the 3.9.
Ooo that could be a good platform for it, especially with a solid front axle too! Which generation you thinking for your swap?
@@Tinker1837 a 1990s 4 runner.
what did you do with your fuel and boost? any upgrades?
Oh yeah, lots of upgrades! It has the bigger Super HX30 turbo, pretty much the largest charger you'd want to run single, before going with compounds. Also I've done just about every upgrade to the pump, & I have videos on all those, but I'm waiting on doing my injector & head stud upgrades until a bit later.
incredible job. did you use a guide all just knowledge you already had?
Thanks! Nah no guide. Thankful for a good friend & my father lending a hand when they can though. But if you're looking for more info on these engines then I highly suggest 4BTswaps.com , tons of stuff on there!
Ahhh my kind of therapy
Now you've got me thinking how I could create a 4BT ASMR video... hmmm...
Tinker your welcome for that idea lol
TheCattlekings I'll make sure you get a cut of the residuals if it takes off ;)
Tinker thanks I only need enough to get my hands on 6bt for my project ford
Thanks so much

Hope it's helpful :)
Looks so agricultural no matter what you do but very sick.
Almost as iconic of a tractor type look to them as the old air-cooled diesels.
May này có ở Việt Nam mua liền
Cool :)
A esa caja de cambios se le puede poner auxiliar para 4×4?
You could, yes!
God damn! If that's not one of if not the prettiest thing on YT, i don't know what is! I would display the shit out of it on a wall in my house or something! :D
Thanks! I think maybe I should've built a few of them.
@@Tinker1837 You should've most definitely built more of them :D
where did you get the nv4500, bellhousing, adpater plate, and flywheel and clutch? can you do a video showing the slave cylider installation?
High Impact, High Impact, Ebay, South Bend. Slave cylinder is an upgraded Valair unit that just bolts right in place of where the standard Dodge slave went in the bellhousing.
Thank you! Can't wait to see more of this project!
I have question.. what company makes that manifold ? and what turbo?
That is a Cummins equal-length manifold (#3901635) & a Holset "Super" HX30W turbo, which is essentially a 4-cylinder sized turbine with a 6-cylinder sized compressor & is considered the best single turbo for a 4BT (before getting into compound / dual turbos)
Love the build! Love the truck combo; would like to do the same swap in my D2. Are you going to mate the Lt230 case and if so, do you need an adapter? Or do you have something else in mind?
Thanks! Keeping the LT230 case & to do so I'll be pulling the "spud shaft" from the output of my current ZF auto trans & just sliding it into the LT230 input (possible thanks to it's input having an internal bearing support) with a yoke over the end. This way I can run it divorced with just a u-joint between the new 2WD style trans yoke. Also lets me rotate the case however I see fit for clearance & driveshaft angles.
Brilliant! Can't wait to see your progress! Sub'd!
Looking real nice and next comes the job of stuffing it into the Disco! What type of Sealer did you put on the tappet cover? I have always put them one with NO sealer on and the never leak, but when I did put a sealer on the rubber gasket ozzed out !
That was Ultra Black RTV. Hope it seals up, that & the front cover too. Both had rubber gaskets that were leaking when I picked it up so I figured I'd see if RTV could put up a better fight.
The new common rail cummins all use Black RTV on the front timing gasket! RTV will make the rubber gasket ozze out as it has happened to me, but if it looks like it is in there for good then I'd leave it! Once again nice build !
That is a good decision to replace all soft plugs with those billet plugs as I have had OEM soft plugs come out in the worst places and times and now I use all billet plugs in all rebuilds ! A cummins parts man told me that they make 3 different sizes of METRIC " soft plugs " so go figure !
I could see that happening, maybe it was the cold that kept the RTV firm enough to save it oozing out. That's good to hear about the plugs! Thought maybe I went overboard on that front, but anything I can do to improve the reliability is worth it to me, no matter how small.
1:30 can't forget the KDP!
Erik Kovacs Yep! Sorted that little monster out in another video, did a quick how-to on 'em.
Why did you change all the freeze plugs?
I put in some of those clamp-in aluminum freeze plugs mainly for giving me multiple places to tap in for heater-core hose fittings & temperature/fan sensors. And partly to prevent them possibly blowing out due to the much higher rpm & boost it will have now vs stock. Also makes for a handy place to drain/flush from & monitor the cooling passages ;)
How was the bottom end?
No bigger injectors?
Solid & not yet, that's actually next on the list.
What kind of power did you make with this engine?
I've not had it on a dyno yet, although it's fairly easy to estimate power levels with these old mechanical Cummins engines based on component combinations. With these original injectors & stock boost setting for the Super HX30 it will produce 200HP & 450TQ... at only 1600RPM! But when I step up to the next size injector, swap head bolts for studs, & bleed a bit more boost from the turbo's wastegate it would put it in the range of 250HP & 550TQ or more depending on how much I push it. Not much more power is safe, or useful down low where I want it, with a big single turbo. I'm doubtful I'll go compound turbo with this build & chase more power.
Buenas cordial saludo
Que precio tiene y cuántas velocidades tiene la caja gracias
What Cubic inch is this block ? Is that a Gt30 turbo?
3.9L is 238 cu-in & that's a "Super HX30"
Hey tinker! I’m wondering what are the block inserts (ex: block heater) I haven’t seen some of the others you’re inserting. What are they??
Those are for helping to heat up the engine in extreme cold, via external electrical sources. If you've ever seen inside of an electric water heater, they are very similar.
How can I find these?
Search for "cummins 4bt block heater" on your preferred parts site. I found mine direct from Cummins, was even cheaper than what I found on eBay!
Do u rebuild any type of engines? I have to rebuild an engine for Toyota 4runner 93, 3.0
I try! That shouldn't be too difficult an engine to dig into.
What trans did you use ?
That's a somewhat custom 5-speed NV4500 manual transmission. Has an advance adapters bellhousing, a larger HD Dodge clutch + flywheel, case itself is mostly HD Dodge as well, but the tail housing & 5th gear are the Chevy version that's shorter + stronger than the Dodge tail.
That onbord fuel filter. Is that all your running? What micron/filter. Arnt the banjo bolts a restriction? Wonder if theres any benifits to bypassing it and using a remote twin fiter pass thru filter set up. An -6. Was my tought. Im identical to this bulid. Glad to see somon else had the same idea.
Or just fitting some 12mm an 90s in and running hose ends to them. And utilize the on bord with out banjos?
That's the Baldwin filter that Cummins calls for in their current recommendations. It's a real fine 5 micron level of filtration. The inner bore of those banjos are very near the hose ID size. Their could be benefits with water separation, but after I run thru a few tanks of diesel I intend to use the Baldwin filter with the water separator built right in.
Tinker right on. Deffantly the dual filters! For 300 hp i think its gonna be fine i doubt ill get any starving issues. Just checkin all bases. Cant wait to see it run!!
Ok the question you probably don’t want to think about, how much do you think you have in this swap?
The good rule of thumb if you do the work yourself with an extensive engine swap like this is $10,000. And of course if you decide to have a shop do the work for you it could easily be double/triple that! Thankfully I've not reached that yet on my build, & I haven't crunched the numbers for several weeks now. But last I checked it was just over $7k total, likely hit $8k by the end so long as nothing too pricey breaks!
Your build quality is great! Want to do one for me?
Chuck Taylor So long as you're okay with a completion date somewhere in 2020 at the rate I'm going haha!
What’s your cost?
Cummins 4390 de retroexcavadora case 580L series 2
?
why did he take the freeze plugs out ?? he did not put engine block heater in ??
Look closer. I did add a coolant heater into one, another plug in the rear is now my heater core supply, & the third is just a simple plug that I may drill+tap for additional gauge sensor.
That looked like a new 4bt
Thanks? From a distance sure, but up close... my paintjob didn't end up all that great thanks to the cold in that uninsulated space.
That grid heater you put on. Did you have to do much to make it fit?
baja5000 No trouble at all, goes right under the original intake elbow with the same hardware even, just remember to pick up the pair of beefy relays that go along with! Found my setup on eBay for cheap, think most 6BT guys ditch 'em when they start pushing the power up.
So its just the stock 6bt grid?
baja5000 Right! And even though the bolt pattern of that intake looks symmetrical... it is off from square by just a few mm for whatever reason. So if at first it doesn't seem like it's fitting, try & rotate it around until it drops in.
Hi there how is the engine going now?
Are you happy with the power Sir?
Running like a champ 💪
Lo máximo
👍
what capacities that engine I main cc? 5.0?
3.9L / 3900cc / 238ci
hola tinker cuanto vale ese motor para México con todo y caja de vel gracias
Great video. I'm building something similar and wanted to see where you found all the components for alternator and hardware. Thanks in advance
Thanks, & the alternator in this clip was just a placeholder for the larger 130-amp Land Rover alternator I'm using now, which also has an RPM trigger wire I'll be tapping into for my tachometer gauge.
@@Tinker1837 thanks for the reply
@@samuelesquivel8088 Happy to help :) Next video I have on this build is actually involving custom mounting the alternator & a pair of big batteries... if that can be of any use for your application.
Great build!!! Was just going to comment on the ugly alternator, because everything else is so nice!!!!!
@@scarface-39 Thanks man! Yeah that one is a bit scabby looking for sure.
Guao tremendo mecánico
Thank you :)
Ok
👍
What did this overhaul cost you in full?
Just the engine overhaul was only a few hundred dollars, but if you mean with the new transmission + clutch + adapters + bigger turbo etc... well then that's more around $5k
Is the bell housing on the 12v the same as the bell house on the 4bt??
Yep! Shares a ton of parts with the 12 valve 6BT's... I mean nearly everything aside from the huge parts (block, crank, head, etc)
Thanks. I'm 4bt swapping my 1980 ford f150.
Nice! Great way to keep an old truck alive & kicking.
I've got a 95 Disco and have been dreaming of a 4BT swap. Love the truck, owned it for years, but I have almost 200k on it now and it is inevitable it will give up the ghost. I'll be watching your whole series. Why did you remove and replace the freeze plugs?
I removed those to replace with plugs that had ports for cabin heater / block heater / and sensors.
So you removed the freeze plugs and blanked them over with something?
Right! Figure it best to do so while the engine was out. All in preparation of the boost going up considerably, just to save them flying out (relying on loctite alone).
How exactly does the boost pressure cause welsh plugs to "fly out" of an engine block??
Never heard of blow-by?
What belt accessory setup is that i need all of that for my 6bt isuzu npr swap
Ebay is a great source for part like those!
@@Tinker1837thank you do you know what there called or what your engine came from
Which part? Most of my parts are actually coming from the 6-cylinder Cummins engine, so cool they're interchangeable!
@@Tinker1837 thanks for the replys
the fan mount
Water outlet/alternator mount
Water inlet
Tensioner
And belt
The belt's a custom fit for my fabricated alternator mount, but the rest is from the 4BT or 6BT that either came with the engine or ebay. I have tons of specific part numbers in my build thread in the description.
好棒技術都不用墊片膠，you won
👍
Did you made flywheel.?
I did not, that is a Dodge Heavy Duty flywheel from a 6BT diesel truck.
Where you buy the motor?
From a well drilling company. It was part of a big pump, if you check out the 1st video in the series you can see the source as I pull it out.
think this will fit in a 88 samurai lol? considering this swap
With enough suspension lift & motivation I'd sure think so!
Weighs more than the Samurai.
Sir you are a great fabricator. Can you please tell, how much a 4bt vibrates? I want to put it in fj40
Thanks! They aren't too bad until the shut-down, then they have a pretty healthy shudder. I love how smooth the straight-6's are though (6BT)
That's because the 4bts are unbalanced, the 6bts are balanced. Hence the reason they are smoother than the 4bt.😁
Shakey lil devils!
I'm a manual for street and racing, but for off road specially creeping up hill and in mud automatic is much more comfortable and safe imo
Certainly are pros & cons of each. Low range, especially with a low rpm engine makes crawling up/down a hill easy. Having a torque converter's handy, but left-foot braking is even better when you get a handle on it. The durability & simplicity of a manual transmission is hard to beat.
@@Tinker1837 hey brother, where did you get the manual pedal set for the disco? I'm getting a frame cut 4bt from that guy in Ohio on Ebay. Looking for the nv4500 and a doubler as well
@@PavelowGunner1122 Nice! I actually couldn't find one for a decent price, BUT what I found out was that the shaft that all the pedals pivot from are the same... and so what I did was pick up a Disco brake pedal that fits right in the assembly believe it or not.
@@Tinker1837 haha, excellent! At least LR did something that makes sense in that regard. That makes life a bit easier. Where did you get your nv4500

Que tal amigo quizás usted me pueda responder ya que mi idioma no es el ingles. Tengo dos motores un cummins 6bt y un perkins T6.354. Cualquiera de los dos quisiera adaptarlos a una pick UP jeep j10. Entiendo que la transmisión que usaste es una nv4500 chevrolet. Mi pregunta es, la carcasa o housing trasero que usaste es de fabricación casera, o es un housing que venden específicamente para estas adaptaciones? Gracias.
The bell housing I used is a special casting for conversions like these, not made by me, but is made by either "Advance Adapters" or "High Impact Transmission".
Ok. Bueno entre a la pagina pero me sale es la campana donde va el embrague. Yo hablo del adaptador. Osea adapter. Que va del bloque del motor hacia la campana o housing
En el minuto 4:40 usted la está montando en el motor
Oh! That you can find from Cummins or Ebay. Here are more pictures & info in my build thread: www.4btswaps.com/threads/land-rover-disco2-out-with-the-old-in-with-the-4bt.100657/
Hey man im venezuelan in my country I have two Chinese 5ton box truck those with those cummins there the same engine they just made in China.
Do you like those engines? I have enjoyed working on mine so far.
