Which 4.0's will bolt into my 1996 ZJ?
« 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?

Not to steal your thread, but will the 4.0L V6 fit into my CJ7. Or is there to much cutting and welding needed?

the 4.0 is an i6 the 2.8 is a v6
build it, beat it, break it, fix it, repeat

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.

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.
