eaglescout526 Posted October 7, 2023 Share Posted October 7, 2023 You sure you don't have an 86? 87-92 only had the 4.0L I6 Link to comment Share on other sites More sharing options...
jdog Posted October 7, 2023 Share Posted October 7, 2023 Could also have the 2.5, but all his other posts are for an '86 Link to comment Share on other sites More sharing options...

zomeizter Posted October 9, 2023 Share Posted October 9, 2023 @Robert U2.8s are weak and failure prone engines which I would not recommend refurbishing. If a 4.0L swap is not feasible, then find you a 3.4L V6 to swap in instead. I still have a 2.8L in my MJ but only because I found a dirt cheap fully rebuilt one out of a wrecked Camaro. When I acquired my MJ it had a nasty rod knock and my intentions were to swap in a SBC V8 into it. I still plan on doing a V8 swap with an LS likely in the near future...

Greenjeans Posted October 9, 2023 Share Posted October 9, 2023 If your carb is good, I can’t recommend a 3.4 out of a 94-96 Camaro highly enough. You don’t have to go crazy like I did. Just swap over your accessories and add an electric fuel pump. My motor was $250 at a u-pull-it yard. There is some risk involved with a used motor but if you look around you may be able to find one with reasonable miles on it. Those cars have analog speedos so you can see the actual miles on the car before you pull it. Just another option for you and it’s a whole lot more motor..

cruiser54 Posted October 11, 2023 Share Posted October 11, 2023 Numbers matching GM engine in a Jeep? The 2.8 is a turd. Always was. Link to comment Share on other sites More sharing options...
