Hey y'all. Before I go on, I just want you to know, I myself will not be doing the work on this one, I have a buddy that has done some work of this sort. I have a 2002 Wrangler TJ with the 4.0 Straight-6 in it. I am looking into getting an older bread truck or maybe just the engine itself, but what I am looking for is a 4BT cummins. I understand that this is a huge project and not just a weekend job. What I need to know from you guys is everything I am going to have to buy to get this thing going. When I say everything, I mean everything. From the engine to the Tranny to the tires and all else. I have another vehicle for the time being, so I am ready to put the Jeep away for a while if need be. So if anyone has done this, and has a complete list of things, that would be the most helpful. Also, any estimates to how much this is going to cost would be appreciated. I am prepared to drop a pretty penny into it... Like I said, im not the one going in blind, so if anyone thinks im over my head for this one, don't worry, I just need to buy all the parts to do the job. My buddy switched out engines before, but hes not completely sure on what to get for a jeep.
