ZJ cummins swap?!
ok i want to do a cummins swap in the near future (after i get a job) so i need to start looking now for parts and engines. does anyone know what year/model is best for my 95 zj 4.0L? i have a dana34 in the front and a ford8.8 in the rear and tom woods driveshafts. i dont know what i need to change in order to support the new engine and the torque. i want to change my front no matter what because its the 3 piece and i want to jump this girl without snapping an axle. just throw out some ideas if u can.
If you do an online search there's a couple ZJ's floating around with Cummins 4BT's in them. I think they come out of old Frito Lay trucks and such. I thought about it once or twice but it'd probably be cheaper and easier to put in a V10 out of a 3/4 ton Ram, and I still wouldn't want to do that.
You want to jump the truck with a heavy *** diesel engine stuffed in the nose? Let me know how that works out for ya

Reliability is relative
I was once one of those 4BT dreamers too. I always thought, "heck yeah I want 30 mpg in a jacked up ZJ"....but you really have to weigh in the costs of the swap. Like people have said; you need to swap out fuel system, and electronics. A lot of fab work on the front end is needed as well. You could find a decent 5.2 or 5.9 for faction of the cost of a 4BT, and use the savings for gas money. Just my thoughts.
