Title: Which 4.0's will bolt into my 1996 ZJ?
Post by: FSJNate on June 29, 2009, 10:44:07 pm: My 1996 ZJ with a 4.0 just let go with 290,600 original miles. What Jeep years and out of which models can I look to for used motors?

Post by: etaucher on July 04, 2009, 04:22:45 pm: I thought I remember seeing some where on the internet, that someone did put a 4.0 into his CJ. But I can't remember.

Post by: Rick_Bear on July 04, 2009, 06:53:16 pm: Anything can be done...Modification being the correct language. With the correct motor mounts it can be mounted in a CJ

The straight six found in the CJ's is a 258 ci (4.2L) [Late 70's and 80's CJ's, older one's could have 232 ci, buick 225 v6, or 4cyl]. The 4.0L (242 ci) is the same block with shorter stroke on the crank. The hardest part of switching from a 258 to a 4.0L would be transfering the computer.
