It would be much easier to put a cummins 4bt in it. waaaaaaaaaay better than the 2.8 and i would say better than the 3.0. I am also assuming it would be an easier swap!
I actually asked Dave @ AEV about the Cummins option as a viable engine for the Jeep TJ and/or JK and his feelings were that the engine is just way too heavy to be a reasonable option for conversion. The frame would have to be stiffened significantly and additional weight added to the rear to handle the front-end weight increase.
