I was directed here from the CJ2a page via a thread that a member had started about working with Bill on a kit for his vintage jeep. He seems quite happy with it and I’ve always been curious about adding a simple TBI system to my jeep. My jeep runs a Mercruiser 4 cyl (Chevrolet) that has a one bbl Monojet carb that I’m not happy with. My goal with the TBI is primarily solving some drivability issues, but if better fuel economy or power are a byproduct- all the better. I’ve read through a lot of the information here and I think I’m at the point of chasing parts but wanted to confirm that I’m going after the right ones- don’t want to buy twice! My jeep’s engine is a 3.0L so the 2.8L TB seems like the logical choice even if it’s for a slightly smaller engine, it seems sized closer to my 3.0L than the 4.3L. My thought is the smaller TB might offer better throttle response (which is what I’m after). On my last JY outing, I spied a 1991 S-10 with a 2.5L 4 cyl that had a complete wiring harness, computer and all the sensors but it looked like it would only support one injector. Will any GM wiring harness work or does everything have to match? Can parts be mixed? i.e., TB from one vehicle, harness from another, and the 7747 ECM from something else? Most of the donor vehicles are coming up on 30 years old, not exactly hanging from every tree.
