A Cummins Mech friend of mine of course is up-talking a mechanical set-up of the 4B(Cummins inline four-cyl diesel motor), but I wanted to see if anyone else has thought about or done a CDI swap.
I would first ask for some details on the Jeep. Such as tire size, transmission, intended use?
Mercedes has always made good engines especially diesels. Albeit some were gutless but they lasted forever. The issue I see with a CDI is mating it up to a drivetrain that will work in a Jeep. After that you will need a complete wiring harness and all associated computers for it to run. Interfacing MB electronics can be challenging. Another option would be a mechanical OM617 but it too has some hurdles. The biggest I can think of is the front sump oil pan.
4bt is another mechanical engine, reliable, noisy, vibrates a lot, good aftermarket and OEM support.
VW TDI would be a good engine for a commuter vehicle.
6bt will fit but it is way overkill.
