XJ engine swap

[jruss]

What range in years of the 4.0 motor can I seamlessly swap into a 2000 XJ? Were there many changes from year to year?

i would swap anything from 91 to 01 then you get the H.O but i would stay with like a 97 or newer since they do have like, what 15 more hp.

Watch out for Grand Cherokee 4.0s 99 or newer, the mounts for everything are different. The newer TJ motors also have different mounts for the stuff up front. I know that a 99 TJ motor will swap into an xj but I'm not quite sure when they changed the mounts for PS alternator etc.

'1999-2001 XJ's had the distributor-less ignition system, so if you put an earlier engine in then you would probably have to put in the wiring harness and computer too... so not so "seamless"
