i got a 89 2 door xj with a 4.0 in it that i cant get to run so i got a 1997 grand cherokee 5.2 (318). anyone no how hard would it be to swap the 5.2 into the 2door??

 

It's a huge project.

 

Computer and harness swap. Custom motor mounts, custom headers. Trans fitment and crossmember. Custom driveshaft. Upgrading cooling system...ect, ect..... much much $$$$$$. Not worth it. If you want to add 2 cylinders go GM. It's been done many times and their are cheap ways of going about doing it. In honesty rebuilding your 4.0 will suffice power needs for the average joe.

 

You're asking too generic of questions. You won't be able to do it.

 

GM is not cheap nor easy. Trust me on that. Is it a better platform than the 5.2? Yes. Cheaper? No. Although, if your pockets are deep enough, novak will sell you everything, including the motor and trans, to make a somewhat easy swap.

 

Are you saying "if you have to ask, it's probably above your skill level?"

 

My apologies. I didn't mean to make it sould as if a GM swap was cheap and easy. No engine swap is cheap and easy. The GM route can be a cheaper and easier option than most as its been done and parts availability. Sorry for the confusion

 

alright thank for the inputs ill mostly like just work on the 4.0. i just bought the grand cherokee for 500 and thought it would be just motor and trans swap with the ecu and motor wireing harness and motor mounts. plus i can get my 2 door to get power in the small yellow wire goin to the icm

 

Yeah fix your 4.0 its far cheaper.

 

yea im goin just trying to find out whats goin on with the power to the icm and relay buzzing. i anti really messed with wires so it all new to me.
