4.0 EFI in a CJ7

[maddhatter]

Has anyone put a 4.0 in a CJ using the stock T5 CJ tranny?
I have been told it can be done by drilling out the undrilled holes in the bell housing. I'm not real sure I'm buying that. Is the shaft and pilot bearing the same? Which fly wheel, bell housing , starter would I need to use?
Any help would be great.



Thanks.

the t5 from a cj will bolt up to the 4.0 jeep motor, but you will not have a place for the CPS. You can either cut a hole and make a mount for it in the T5 bell housing or they make a kit to put it on the from of the crank. I would put it in the bell housing. I buddy of mind put a t18 behind a 4.0 motor and made a mount for the CPS.

You would need the 4.0 flywheel and starter. The starter should clear the bell housing.

A 4.0L would also need all the other related electronics to make it run right, that's where I see a PITA coming into play.

So can I use the tranny from the YJ and hook it to the CJ T-case?
