    Hi y'all, I'm new to the forums, this being actually my first post. Just wondering, is there any way possible to swap a 2.8 diesel into a 3.7 gasser? I'm not too familiar with the CRDs, what are they like for power/reliability and how do they preform with mods/tunes etc.? Or maybe they aren't worth swapping? As you can see, I'm not a pro about this kind of stuff. Thanks in advance!

    Much too difficult to do. As far as I can recall on a LostJeep post the CRD has a lower cradle under the engine as the engine needs to sit lower.

    Then engine mounts would be different, all wiring harnesses and PCM/TCM/BCM/FCM etc. need replacing.

    ABS system is different and I would not like to know how to connect the various transmissions up.

    Large Bosch injection pump up front needs to be fitted, Vacuum Pump and special Alternator with over-run pulley needs to be fitted.

    Much as I love my old CRD, this is Not a robust engine....Rubber Timing Belt.. and Diesels are becoming the main target of the Bunny Huggers....ie. Tunes have been outlawed!

    Not that I have anything against Clean Air or Bunnies!;)

    Post your question on LostJeeps and I think you will get your answer!

    You'd need to go crazy first. But if you're already there... Or that's where you want to go...:D
