Cool Cummins 4bt Engine Swap



Anybody done anything like this? I have interned at Cummins the past two summers and drive a TJ and think this would probably be the coolest thing ever. Obviously I would prefer to do the swap myself. Anyone done the swap personally or done something similar? I'd love to hear your input.

I've been thinking about doing a 4BT swap in my J10. The 6BT is just a little too long to do it without major surgery. I figure I could build up a 4BT with a good intercooled turbo to make enough torque to move the truck around with my CJ on a trailer behind it. Sure it wouldn't win in a race with a modern diesel truck but I bet it could hold its own heading out I-70 to Moab.

I did it to my YJ! Best engine swap I have ever done. I can even help you out with the engine mounts if you decide to do it!

Here is my ongoing build
