Well im starting with my 2.5 yj 5 speed. 2" body lift on 32's. The motor blew last week and rather than rebuild or replace, I'm upgrading. In this thread I will track and report my progress.

Cool! I hear the 5.2L and 5.9L Magnum V8s are pretty easy swaps as well...might be something to look into.

I'd love to put a v8 in there. Unfortunately I'm only doin this swap because the engine blew and I'm only upgrading to the 4.0 cause I can't find a local 2.5. I'm really pressed for money haha. At least with the 4.0 I just need to replace the engine trans and t case. If I put in a v8 I think I'd also need to change my driveshafts and rear axle at least

Good point. Have you found a donor 4.0 yet?

Yea originally I found a separate 4.0 and trans. But the 4.0 was for an auto and the trans was manual. Today I found someone selling the 4.0 auto trans and t case. All they want is to trade for my ax5 and t case, plus $200 for the engine since mine is blown

Got the trans and t case out, haven pulled the engine yet due to lack of engine lift.
