will it work

[mj88]

I'm tryin to find a 4l engine for my brother in law cherokee, and was wondering if a 92 4l cherokee engine will work in a 96 cherokee. if not any one know what will work in the 96.

92 was a HO xj so that should work, computer systems may be different though.

I'm pretty sure 92 was OBD-I, federal govenrment madates that all vehicles 96 and newer need to be OBD-II.

 

So yeah, computer probably will be different,

 

I'm guessing the engine itself is the same, but you may possibly need to swap some of the sender units over from the old one.

 

I really know nothing specific about the HO, as my only experience is with the Renix (87 through 90).

will the auto trans from the 96 work in the 92 engine?

[JeepcoMJ]

yea, the 92 motor will work.

 

you'll have to swap alot of things from the 96 motor over that you can

 

you need

96 flywheel/fledplate

distributor (for safe measure though 92 may work)

throttle body and sensors

coolant sensors

oil pressure sending unit

02 sensors (not sure if this is 100% necessary swap)

fuel rail and injectors (not 100% necessary, but a good idea)

 

the most important thing I can tell you to swap is the flywheel/flexplate. we recently installed a 93 motor in a 95 xj after rebuilding the motor, and found that the flexplate was different and would not bolt up to the torque converter AFTER we installed the motor :roll: so we had to take it out and swap out the flexplate :( which just cost us time.

additionally, depending on emmisions laws, you might be prohibbited from taking an engine and installing it in a vehicle newer than the engine

i believe in new hamoshire if you have an OBD-II controlled emissions system and you put a motor in that was born before 96 then you don't have to apply to the OBD-II laws. not sure about anywhere else

[mj88]

lucky were I'm at we don't have any emissions laws.
