Yes, more information on the 4bt swap please.

EDIT: Actually, after some searching, I'm not sure I would put something that heavy into a unibody, and you would have to fabricate a lot to fit in the NV4500, maybe a lighter turbo-diesel though?

Thats why I said a 6.5 its not as tunable but still would give you good power to weight and its lighter.

Naaahh, skip the heavy pigs like V8 GM diesels or Cummins 4bt, and put in an old Merc diesel (OM603/606, or even a 617). XJ is light vehicle, so you can easily use passenger car engines. The old merc diesels are all pretty durable and tunable engines. Stock turbo internals of a 603 or 606 should handle up to about 300hp. Stock engines aren't that powerful, but rather spectacular when built right

Don't know about their street-legality in the USA though.

This one is with a slightly newer merc diesel IIRC:

YouTube - MB 300 turbodiesel

As I said in my previous comment, my other car is an 83 Mercedes with the 5 cylinder turbo diesel. It's not a light engine but I don't know how close it is to the Jeep engine in weight. If you want to look into tuning one check on PeachParts - Mercedes Parts & Tech Info
The first car in your videos has an amazing engine in it. I will look around, I have seen pic. of the engine and the build up of the car.
