If you have emmission checks in your state, dropping in an older engine is a no-no. Not sure on off road vehicles.
I see a bunch of potential problems. First is motor mounts. In 88 the Wrangler used the 4.2. I am not sure if the 88 motor has the bosses needed for the Wrangler. I bought a 95 motor out of a Wrangler. They guy had an '00 out of a Cherokee. He said he couldn't use it, because the motor mounts wouldn't bolt up. I compared it to my '03 out of a GC. The front bosses were not drilled and tapped on the '03 block. I'll try and check tonight and compare the '88 block in my Comanche.
You would need to source a wiring harness and ECM for the correct year(let say 95), tranny type(auto or stick), and 4WD or 2WD. If you already have an auto tranny, I'd check Advance Adapters website for info.
You would also need the flywheel and crankshaft position sensor for the year you are converting to.
If you have a manual tranny, I think its an AX-5. I am not sure if/how it would bolt up to the 4.0.
There are a lot of website with conversions in the Wrangler. You really need to think this through. Plus you might need to source or modify your tachometer. Since yours is a 4 banger, the counting sensor is different for a 6.
