I found a rebuilt 1984 2.5 liter engine out of a cherokee for cheap. Is it the same ( within reason ) as a 1990 2.5 liter? I just wonder if I could make it work without too much trouble.

I am not sure, but I think they were injecting the 2.5 a lot sooner than they even offered the 4.0.

Thanks. I have started to take the accessories off of my engine and am going to use a good short block for the rebuild. I think you are right about the problems with trying to adapt the carb setup to the throttle body injection.

JeeperDon, I have always thought that would be a good swap. Of course I'm a chevy guy from way back. Did it bolt up to your tranny or did you need an adapter?

The AX-5 is not tough enough, so I went with an AX-15 (from a junk yard, $75). Then the t-case input is wrong for an AX-15, so you have to swap the t-case input shafts, or just get the junk yard t-case too. That makes the swap look like you have a 6-cyl, so Advance Adapters has everything you need from there. The nice thing about a 4.3 swap rather than a 350 is it is shorter and lighter, yet has the exact same back end as a 350, so adapters are easy.
