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! -
Is there a manual transmission that can handle an 800 horsepower racing Jeep 4.0L stroker engine? I need a 2- or 3-speed only transmission. -
Has anyone used the Novak conversion kit to install a 5.3 LS into an XJ Cherokee? They have the whole package including updating the wiring harness and GM computer along with the XJ computer. -
In 1984, AMC/Jeep® took its unitized body and 4x4 technology into the XJ Cherokee platform. This breakthrough compact SUV became the best selling model of its era and made the AMC sale to Chrysler profitable. These models and the subsequent Jeep ZJ and WJ Grand Cherokees feature beam axles front and rear, two-speed transfer cases and rugged engine packages, making them candidates for off-road upgrades and 4x4 trail use...Welcome to the XJ Cherokee and ZJ/WJ Grand Cherokee community at 4WD Mechanix Magazine!—Moses Ludel At left is a ZJ Grand Cherokee equipped to tackle the Moab Area BFE course!
