What the guy doesn't tell you is that the engine has something like 76hp and 174lbs-ft So I don't know why this guy think it would be a great swap in a Jeep. The VW diesel is smaller and makes a lot more power stock and with a reflash, makes a hell of a lot more.
it has mechanical injection, that's an advantage imo for simplicity, you only need 2 wires to get it working, the fuel valve and the starter solenoid. The vw has a lot better injection system but it is computer controlled so lot more complicated to get it going/working in a Jeep. it has plenty of torque but like you say less power by quite a bit (and that's b/c of the low top rpm mostly), so hwy speed might suffer but offroad would probably be great.
I remember reading about an isuzu swap at some point, it requires an adapter plate for AX15 or similar and some clutch disk to work with the existing flywheel/pressure plate. also from the video it seems that the starter is located on the driver side of the engine, that would/might need to be also relocated or something to be modified on the bellhousing to provide clearance if needed (could be as simple as cutting and welding or bolting on a piece of aluminum for protection if there are no structural issues on the bellhousing in that spot).
