Question for the 4.0 swap guru\'s
Wanting to swap in a 2001 4.0 and use my MPI kit. Would the distributer, MPI intake, fuel rail, etc. from the MPI kit bolt on the 01 4.0? I was planning to use the 01 4.0 exhaust manifold and the MPI intake. I had heard that the bolt patterns for the intake and exhaust were different from the 91-94 heads???? How about the flexplate and starter from my 258, will they work on this late a model 4.0? The alternator is another question. I know the 01 alternator is different but could it be wired to work w/ the kit? I remember putting a diode in one of the wires when I put the MPI kit on. I'll get a 4.0 damper/CPS to work w/ the MPI kit on the 4.0 unless the bracket/CPS from the MPI kit(for the 258) will bolt to the 4.0 oil pan, then I'll use the CPS that I have. I've tried the search function but haven't found a post relating to the way I want to do it. I know this is a long post but I appreciate all info.
Well, one question has been answered. I would need to use my existing alternator. Does this late a model 4.0 have the mounting holes for the cj alternator brackets? Also I have heard that the motor mounts are different from the 91-94 so this isn't a direct bolt in. Anybody know this stuff for sure? Thanks again.
