2000 cherokee 4.0 swap
Ok my grandpa. Blew a window in the side. Of his block and im looking for a motor for him. I seen a 90 block with a 96 head. On craigslist. That has ben completly rebuilt. With recepts what all will need to be done. To get this motor to fit. There is a 4.0 out of a 01 bit they could have they same problem. With the head cracking. Am i rite. And i cant hear it run. Because. Its already out of the jeep. I am told it runs good with good oil pressure but. Iv. Ben got befor i know. I will need headers for the older style. But what would be the easyest way to het him back on the road. Thanks. In advance

I thought fuel injection on the wrangler "YJ's" didn't come out until '91. Not sure about the XJ's.
I bought a complete motor and trans on craigs list. I made the guy warranty it against DOA. I only put motor and forgot trans! Sigh. Yes, trans was bad. Motor fine. It's just a thought, but, have him sign something, with his name (print his first & last), address, phone number for DOA on motor. If he is pulling a fast one, he won't sign it. My $.02 |
Ok. My main. Thing is. What is the. Best swap. For these. Trucks. To not have 0331 head. And not have. To much work on my hands. So i can. Get. Gpa. On the road aagian

Have you tried the bone yards? They give a warranty (it's extra). But, you can find a low mileage one I am sure. I was at one yesterday, and they had a '98 there. Is it the head or block that went? |
Yes i am on my cell. Well the. Head. Cracked. And. Alowed it to over heat. And it blew. Out the side of the block. I have looked at bone yards but im scared to get. A. 0331 head. Because. They are. So prone to cracking between 3 and 4. Dont want to end up in same position

A 90 block with a 96 head should be fine in any 91-01 XJ...as long as it was rebuilt well.
Like the YJ's, the Chrysler FI on 4.0L came out in 1991. Before that (87-90), XJs used the Renault/Bendix (Renix) FI on 4.0L's. The head was also tweaked in 1991, riased in the intake ports I think. |
thank you very much i will look for one is ther a better year to got motor from or they all pretty much the same
|
