MJ4BTA

You need a Bosch VE pump timing tool. The cheapest place to get one is dieselvw.com. As far as the lift spec with the crank lock pin installed, and the belt cogs lined up to the cover, I have found three different ones listed for a Renault J8S-814 and 815 engines. The most recent Renault manual I have lists 0.70mm, but the old AMC Jeep service manual lists 0.8128mm(0.320"). I have three of these engines and a bunch of parts/info. If you have any other questions, let me know.

I'm sure the 44 will hold up fine, If you upgrade the shafts and carrier. I'm running a Detroit TruTrac and Superior CroMo replacement shafts with about about 120k miles on them and well over 400ftlbs at the wheels. It took me 20+ 1-2 powershift burnouts to shear the pinion, and when I replaced the gear set, the splines and carrier were perfect.

How tall is that scoop? Where can I get one? I need a small scoop for the passenger side of my hood because one of my turbos is about 1.75" outside the sheet metal, but I need somthing narrow enuff not to overlap the groove in the center of the factory hood.

I added pwr windows mirrors, locks, and windows to my 87. You need the harness or 2 that runs from kick panel to kick panel. It also has its own terminals that go to the fuse box also. Its not that hard to accomplish, all plug in, as I remember. Good luck.

Sorry for the hijack. Who's in for the trail ride?

With mechanical injection, the throttle response is equal to a fuel injected gas motors response.

The yellow MJ in the last pic is mine, Cummins 3.9L 4BTA. I don't have the newer nose swap, but I have been in Readers Rigs once and in Diesel Power twice. There was a nice yellow MJ in JP with the 97+ nose and interior last year, I think?

Witch one? When he says "WARNING: Body Damage Including, Scratches, Scrapes And Dents Are Very Common", he's not kidding, and I think thats aimed at me. The ride the second and last pics on the flyer were taken at, BARILLMS peeled about a foot and a half off of his bedside 5 minutes into the ride! My brother and I left that one early. I'm not into to twisting sheet metal on my favorite yellow play toy, thats why I'm building a trail only MJ. BARILLMS, you got any more pics of my yellow MJ or my brothers red and black 4Runner? Id really like to get a larger version of the flex pic from the flyer.

hackedxj, that XJ is so cool looking! I have a 94 2dr that I cut like yours, but its not intended for ANY street use, so it will have less glass, and more tubing.

Actually, I just picked up a 88 MJ Mertic Ton and a set of 79 3/4 Ford axles. If I can find the rear fenders that were used on the white MJ dually that was on eBay, I will have a dually.

rockhardzj, I would like to get more info on your MJ! I was thinking my next one might have a 4.7l involved, got any pics?

a1awind, these motors came in ALOT of off highway applications. Ive seen them in small track hoes, Case style bobcats, wood chippers, and large pumps. If anyone is looking, do not get a nonturbo version, 70-80 hp, and the CR ratio is way to high to convert to rurbo, not to mention the completly different injection pump. The only on road application that I know of was the bread vans. Most of them were 6.2 and 6.5 Chevy diesels that were "repowered" with the 4BT's. Like most industrial diesel engines, my trans is not bolted to my block, it has an adapter plate between the two. I know in the step vans, there were at least 4 different bolt patterns, SB Ford, SB Chrysler, GM BPO/Chevy(dual pattern) and the 15deg right tilt Chevy, all availble in standard and automatic versions. I choose the Dodge Cummins version so I could run a drivers side starter, and all the Dodge NV4500 transmission pieces.

If you had the body shop with the bright copper 4dr XJ with the explorer wheels, explorer fender flares, three link front suspension, 33" BFG mud's, and the cut back end with the stock fuel tank on top of the rear floor, and we came there in a bright red crew cab Ford Powerstroke, than yes that was me! That was the second longest nonstop road trip in my life. Erie PA to Chattanoga TN in 22 hrs. You never sent me pics of your rig in action at Tellico. Also, did you get your MJ project finished? When I saw it the 8.8 was just being fitted in. I plan on getting down to Tellico this summer, with a few other vehicles, maybe you could show us around.

I tried to find a factory yellow 2 door XJ before the Comanche got painted blue, but I changed my plans.

Thanks for the compliments! Those pics were from 4 days after I got it on the road. The engine bay aint quite that shiny anymore. I think it looks better now with my winch bumper. Its funny someone would mention compound turbos, I am on my fifth turbo setup in 4 weeks. If I can't get what I want out of a single, twins may be the answer. Space will be a problem, exhaust routing being the worst. Ill build and test the system before I make a cowl hood or full exhaust. That way if it doesnt work out, I can turn back easy. That is how I have been swapping turbos, leaving everything intact from the previous setup, just in case. The only pic of the intercooler is during the paint process. The mounts are behind the header panel and run between the upper and lower radiator mount. When I get it back in my shop for the Dana 60's, I will take some better pics while its torn down. In the pic it kinda looks like the upper radiator hose is inline with the exhaust manifold, but its not. The only time I have seen this is in marine applications. They are very easy to spot, huge double walled exhaust manifolds and turbocharger exhaust housings. The hydraboost is from a 94 AWD Chevrolet Astro van, and it works great! The gear driven high volume pump in the engine, the ZJ rear discs and the Durango box can't hurt either.

Most of the specs can be seen at http://www.4btswaps.com/forum/showthread.php?t=585 Its geared mostly towards the Cummins conversion. I will post some general pics in the next few days. If any one has any specific questions, let me know.

The closest thing to a build thread was after it was on the road. Most of the specifics can be seen at http://www.4btswaps.com/forum/showthread.php?t=585 If any one has any specific questions, let me know.

I have all the info on it, its mine! If you have any questions let me know.

When I built the truck, diesel was about $.60 LESS per gallon than regular unleaded. Now not only does the fuel quality suck, is also sucks my wallet thin. $.50 cent more per gallon or not, I can get 36mpg unloaded, if I drive like a 100 yr old woman, If I beat it like always, I average 26-28. The worst mileage per tank to date was 20mpg fully loaded towing about 7k lbs. Thats also making about 200hp and 490ft lbs at the flywheel with my present mods. When I finish the Dana 60's, I'm sure the added weight and gear will bring the mileage down a bit, but I want the durability of the 60's for towing my trail rig on my gooseneck. This project was not cheap, and its not over, but boy is it fun!
