  1. I haven't started a build thread here yet, but I figured now is as good a time as any. My MJ started its life out as typical base model Comanche Custom with the 2.5L TBI, AX4, NP207. It is now undergoing some major surgery as I am taking on the infamous 4.0L swap. When it's all said and done, it will have a Renix 4.0 from a '90 XJ, an external slaved AX15 from a '96 XJ and either a NP231 or NP242. I have a build thread over on CherokeeForum ('86 Comanche DD) and I will continue to update it there, but as of right now, this thread will start where that one left off. Also, to aid fellow members here in potential swaps of similar nature, here's my photobucket album: Comanche. More in the next post...
  2. I know, I know... this topic has been beat to death so much that a well trained mortician can't bring it back from ruins. Anyway... I'm not sure why so many people have told me that swapping in a 4.0 into my '86 MJ will require massaging the firewall with a BFH. The only problem I've seen is 4.0 radiator fitment and the hood latch is going to have to be changed. From everything else I can tell, the length front to back and side to side are near identical to that of my '88 XJ with a 4.0. So, what gives? Can someone shed some more light on this for me? Perhaps I'm missing something? My goal is to snag an HO engine and AX15 (external slave) and mate it to a Renix 4.0 wire harness and ECU. Will that work also, assuming fitment isn't an issue?
