Hi 4WD Mechanix,
I love the site and am so happy you are fielding questions from common folk like me! Your troubleshooting guide for the 2.5L TBI helped me turn my limping MJ into a reliable daily driver!
Current set-up: 1987 MJ, 2.5L with AX-4 manual transmission, 2WD.
Future: I want to convert to the multi-port FI. I have all the equipment, ECU, harness, manifold, etc., from a donor engine.
Question: Do I need to change the RENIX flywheel to the MPFI flywheel? I have the MPFI flywheel on my work bench (the RENIX is in the truck), but whether the flywheel needs to be change will affect when I do the various upgrades. A flywheel change requires me pulling the engine.
Thanks again!
