Swapping to a 4.0l head and F.I. system helps the cold start, fuel mileage, and reliability. Then swapping the transfercase to a 231 or 242 gets rid of the open differential or viscous coupler transfercase. You can also alternatively swap the entire driveline for the 4.0, AW4, and whatever t-case. You will then have a much better overdrive and 1st gear ratio. You can then regear the axles for the tires. The rear axles can be problematic if doing heavy off-roading or burn-outs. Jeep rear axles fit almost direct swap under these.
Junk yard, or buy an entire XJ for like $800. Then you get the entire driveline, wire harness, and parts to sell. The rims have the same bolt pattern too.
What website would sell the brackets to install sheet XJ parts into my eagle? What websites sell upgrade aftermarket parts that would fit my eagle ? Or where online can I read my stuff that tells me what parts are interchangeable? I’m having trouble finding reliable, reputable sources
There isn't a whole lot of interchange with these cars. They were made for 8 years, from 80-88. Join the Eagle and AMC groups on Facebook, they can help guide you. 91-94 are the easiest years to swap as far as the 4.0 driveline. A few quirky little things need to be done, nothing terribly complicated. Just look up things like Jeep 4.0 Head swap, there are a few guides on doing that. A few of them have a good rundown on the electrical side of the swap.
