I know this has already been discussed on this forum already but I am considering putting a cummings 5.9 diesel into my 87 j20 now that I'm ready to put it back together after a 3year restoration. What years engine should I be looking for to make the swap easier, I don't want to have to deal with newer computers and pollution controls. If anyone has some pictures of the swap I would like to see them. I have run a search on the subject but to pictures don't show up on the older posts. Thanks

do you want to have an intercooler??? from 89 to 91.5 they had no intercooler... from 92-94 i think, was the mechanical setup w/ intercooler... so that range would be you're best bet...
just thought i'd show off mine a bit... my dad had an old '77 jeep cherokee chief that broke down and sat in a field for quite a while... he was about to the point of hauling it to the crusher when i piped up and asked if he'd just give it to me... it was purchased by his car dealership and the title basically dissolved at

1989-91.5 no intercooler just a cross over manifold uses rotary pump
91.5-93 intercooler with tubing to grille and back uses rotary pump
94-97 and early 1998 inline p7100 pump with intercooler tubing to grille and back up
those three are the simplist for a conversionCherokee S Chief Widetrack W/ Cummins 4bta Diesel, 91 dodge intercooler, hy35/9, AC NV4500/D300 3.54's Ploks 4" BJ's w/ 33's, scout 33 gal fuel tank ( Sold, to a good fsj home)
