4.0 Motor differences between the TJ, Cherokee and G Cherokee

[Grumpy Dwarf]

What are the differences, if any, between the 4.0s that came in the TJs, Cherokees and G Cherokees? I may need to replace the engine in my TJ and was wondering if I could use any 4.0 or if there are some that won't work in the TJ.

if you use your original electronics and fuel injection, intake and throttle body, etc. there shouldn't be any difference. but start swapping electronics..... I have No Idea !

As long as you do not use a WJ block then you should be fine. They motor mount points were a little different per a friend of mine. I personally have not ran into it. I always try to stick around the same year, if you do that with the TJ then you should be fine. There are subtle differences between them, but nothing that should keep it from working.

Thanks for the input guys, I've seen a lot of XJ 4.0s and engines from WJs on craigslist but not many TJs. I haven't torn into it yet so I am not exactly sure what is wrong with it, but if it needed another engine then I wanted find out if other 4.0s were compatible. Mike if I end up needing one I'll give you a call.
