Cummins 4bt Engine Swap
 
Jeep Diesel Conversion - 3.9L Cummins 4BT Turbo Diesel in 2008 Jeep Sahara - YouTube

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.:thumb:

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

Jeep should start offering this. All the kits are so over priced
