Idk why everyone thinks it's going to rip the body apart. Let's see the 4bt weighs around 750 pounds, and the jeep i6 weighs 500ish add a winch and bumper on front of that and you around or over the weight of a bt4. Just make a crossmember for the motor mounts and I believe you will have more then enough strength for the new motor.

well i been doing A LOT of research and on the 4btswap forum i found a 4bt xj swap and it pretty much showed how to reinforce the unibody to support the weight and be able to with stand the torque i havent read all of it yet but from the looks of this forum it pretty much breaks down the whole swap also when i start the swap im going to make a video of how i did it so for future xj swappers they wont have to go through as much hassle to find info on it but thats at a future date and ill add the link on here.

Instead of swaping out the dash why not use the original xj sending units installed on the 4bt? They are both chrysler products so they might even be the same sending untis anyway. I doubt you could get the tach to work but the others should be doable.
Use an early auto trans (727) and you should be an easy fit to the np231. It is only a 3 speed auto but works well and does not use a computer.
I would hope you can get 30mpg. My 1ton dodge 6bt gets 22mpg if you drive it easy.

A very large amount of bread trucks ran a 4bt paired to a gm turbo 400. If you get a engine from a bread truck you could easily run a trans and t case from a 70s chevy pickup.

not to mention that would also more than likely have the new process 205 case which is much stronger than the 231 and you would not need to do an sye since it comes with a fixed yoke

Just wondering, have you contacted these guys yet? Seems like they've already done all the research you need to put a 4bt into a jeep.

As for being over priced, I couldn't say. It sure seems like it would be a better value for people who don't want to spend the time or moeny to figure it out on their own and would rather draw upon someone else's professional experience. Just sayin' ...

so i been looking for a 4bt back home i dont want a new one or rebuilt one i was looking for one that needed to be rebuilt and there was no luck but i ran across my buddy who has a 97 dakota with the 3.9 v6 so im debating if im going to put that in or just put the stock 4.0 back in it and stroker it out give me you guys thoughts on this either way i ccan get both engines cheap and i still have to redo my powertran due to being a 2wd so cant add those in im going for performance in the long run im kind of leaning towards the 4.0 stroked out get back at me let me know what you guys think thanks
