500 MJ Posted June 11, 2011 Share Posted June 11, 2011 I think (I don't have anything handy to back it up) that you are going to see more issues other than the AC stuff between the '93 (4.0L High Output) and the '90 (4.0L Renix). The two models are not interchangeable. You're talking different computers, different flywheels/flexplates, fuel pumps, etc. here... The Renix years were from '87-'90. Everything after that was H.O. '91's were a bit of an oddball though. Link to comment Share on other sites More sharing options...

My dad is a jeep mechanic by trade we put the 93 Cherokee motor transmission and transfer case in my 90 comanche all we did was change the flexplate and distributor over from the original 4.0 Link to comment Share on other sites More sharing options...
500 MJ Posted June 11, 2011 Share Posted June 11, 2011 Good luck. You've got quite a few more things to change over if you want to run it with the Renix system. Link to comment Share on other sites More sharing options...
