[QUOTE="gixxerkid3, post: 435997"] HI all. Question. For my ‘92YJ, swapping from a 2.5l manual to a 4.0l manual…If I had a donor engine / transmission / ECU and wire harness and was using my NP231 transfer case, what other items would I need to swap to a 4.0l? I would assume a drive line set up, new engine mounts welded in, exhaust or exhaust mods, what else Would be needed? Thanks [/QUOTE]
