Jeep TJ diesel conversion

Your best bet for ease of installation is to use one of the GM V8s that were popular(?) in the eighties along with a GM transmission and a transfer case adapter from Advance Adapters, but why? There was a web page from a guy in Littleton, CO who put a 350 cid V8 diesel into a mid-eighties Cherokee that originally came with one of those wimpy 2.8 liter V6 gas engines. These (diesel) engines had a lot of problems, chiefly with defective head bolts, but there are a number of fixes including better head bolts and cylinder O-rings that are supposed to be able to make them more reliable.

Another option is a four cylinder diesel from a bread truck, UPS truck, or the like. Many of these come with NV4500 transmissions that can be adapted to the Jeep's transfer case. Separating the engine and transmission from its current owner is likely to prove expensive however.
