gte636p Posted February 23, 2015 Share Posted February 23, 2015 The cheap 88 MJ I picked up seems to have thrown a wrench in things (mainly 2 psi oil pressure after 30 min of diving or so). My solution is a complete OBD1 swap that is sitting around my place right now. The motor should bolt up and the wiring harness behind the dash might get interesting, but my first concern is the return on the fuel rail. My donor 4.0 is from a '94 xj. Is it possible to find a pump sending unit / module from an xj in the junkyard or is it a bit more difficult than that? If I haven't found the right conversion thread yet please point me in the right direction... Link to comment Share on other sites More sharing options...
Crash Posted February 23, 2015 Share Posted February 23, 2015 HO fuel pump/sender is what you need for HO electronics/cluster. Flywheel/Flexplate are different HO/renix. Are you just swapping engine and keeping Renix stuff? Or a full HO OBD1 swap? Link to comment Share on other sites More sharing options...
gte636p Posted February 23, 2015 Author Share Posted February 23, 2015 Got the motor, transmission, transfer case, computer, and engine wiring harness (for $400!!!) .... going all out for HO OBD1. Link to comment Share on other sites More sharing options...
