Craigslist find in Raleigh, NC. POs were trying to take 2 MJs and make 1 good one. Originally a 2.5l / AX-4 / 2WD. At some point in the past a 4.0 swap was started but didn't get far. The engine and engine control harnesses were swapped, along with a Renix 429 ECM. That seems to be as far as they got. Currently has an early era 2.5l bolted to the mounts with an AX-5 behind it. The 2.5 I say must be early era because it has provisions for a mechanical fuel pump on the passenger side of the block. It does have a single popper TBI intake on it right now. I briefly considered pulling the 2.5, light hone & rings, recondition the head, fix all the leaks. But to have any fun at all with it, I'd need to invest in converting the AX-5 to 4WD and end up with a weak combo not capable of doing much more than pulling itself up a steep hill.
Plan:
1) complete 95-99 drivetrain swap and run it on the Renix ECM.
2) (re)build fuel system, kind of suspect at the moment
2) acquire HP 3.55 Dana 30 front axle
Goal:
light duty factory-ish (to start) good, reliable runner 4WD for climbing/ hiking access roads on trips in western NC/ beyond.
Shopping list:
1) complete 4.0l / AX15 / NP231 drivetrain (acquired 93 YJ 4.0/AX15/NP231 July 2022)
2) late HP Dana 30 from an XJ, front shaft
3) figure out rear DS length, cut & balance old one or have a new one made
