I am not trying to start a flame war, by talking about Cummins in a GM forum, just trying to get the most information as I am considering this project. So, I need to complete a PROS / CONS list and post it here. Maybe a person could tweak a 6.2/6.5 for more power, but it looks as if the Cummins could take more mods, thus maybe more power? On paper, they look similar, HP and Torque, just that the 4BT get better fuel economy. So, my goal is trying to determine the performance differences between the 6.2/6.5T and a tweaked 4BT.
No matter is I would go with a 6.2/6.5 or a 4BT, everything else would be the same.įor example, I would use a Chevy tranny on either engine, probably a built and diesel prepped 700R4. Yes, I agree that a 6.2/6.5T would easier it install be using standard Chevy Mounting brackets.īut, if I were harvest a 4BT from a Chevy P30 van, I feel that some of those frame side mounts could be easily modified to work on the FSJ frame. You comments in a recent post on the IFSJA (International Full Jeep Association) that had you to do over, that you would have gone with the 4BT.Īlso, another new IFSJA member in the same post indicated he done this conversion several time and buddy get 34 MPG consistently. Maybe I will make a more complete PROS and CONS list and post it here. It seems as if the PROS and CONS on both engines are about equal. My point of making this post was to gather opinons and more info about why a 6.2/6.5T would or would not make a better swap than the Cummins 4BT. Other folks have performed 6.2 and 6.5T swaps into Full Sized Jeeps. On the other hand, the Cummins 6BT is a wee bit to long. The Cummins 4BT fits FSJ's engine bay well. If that Wagoneer has a seperate steel frame, the only problem will be the heighth of the Cummins engine - will it fit between the hood and the front suspension.Ī ring for the Chevy clutch housing was a standard option, so you can use the NV4500 5-speed and other GMĪ ring for the Chrysler bolt pattern is also available, so you can use the NV4500 or Torqueflyte trans from the big Dodge\Cummins setup.Īll Full Sized Jeeps (Wagoneers, the original Cherokee, J Series Truck) have a seperate steel frameĪ few other folks have performed this swap with good results.
