Okay I have a 1996 2.5 5 speed cherokee I blew up the 2.5 and I have a full donar grand cherokee I think around the same year I pulled the engine and tranny and the wiring harness now I just need to know is there anything else I need to do the swap I'm staring this tomorrow. I have the tcase NP231 the drive shafts etc. Ready will the wiring and computer work for the 2.5 fuel pump ignition etc.

 

See what others say...Normally the Puter' matches the year (group), and the engine. No, the 4 cyl puter will not work in a 6. Grand might have different mounts....Not sure if the harness for the 6 will work in a 4 Cyl. But hey! Maybe I'm mistaken!

96 was a transition year Btw. Some stuff might be like a 95, other like a 97. (at least for the 4.0, I'm not positive about the 2.5)

 

I looked into swapping a 4.0 into the 87 2.5 I had. Decided it would be easier to swap a small block chevy in it than a 4.0, even though I had a complete 4.0 donor Jeep. There are a lot of differences between the 2.5 and 4.0 Jeeps.
You'll need the engine, tranny, engine mounts, radiator and its mounts, exhaust, computer, wiring harness, etc. It's a lot of work.

 

And the grand cherokee unless its a 93 will have the wrong trans for the xj.

 

Sometimes I wonder how hard it would be to graft in a 250 chevy straight six and a four speed ???

 

I'd go for a 292, monster torque !!

 

I figured that would be too tall to fit under the hood.

 

Never thought of that. Been so long since I've seen one

 

I did an in-frame on one back in the mid-1980s. But that was in a 1966 chevy pickup and you could climb in there and go to sleep beside it if you wanted

 

Correct.

GC is a POOR choice for engine/tranny swap.

 

A 2.5 stroker from 505 Performance would be a simple plug-and-play possibility.

 

You still out there? You can see all the comments about the grand stuff not fitting. It would be lots easier to get the donor engine from a 96-97 Cherokee. You can get the wiring and ECM while you are at it and make life easier. I did a quick search online and found plenty of running junkyard motors around 400 bucks. 96 was a bastard year, outside and interior look like 91-95 but the motor has some of the stuff from the 97. If you stick to Cherokee and 96-97 you will have it much easier.
