If you looking for serious power, do a 5 cyl TDI swap from an Audi (Eurpoean). I have a LT31 Florida (hightop) running 22psi and it's still slow. It's not nearly as heavy with highway gears too.
Cummins is too big to fit properly. You have to cut out much of the floor and fabricate a custom cover. I helped a bit with one a few years ago. Gobs of power, but very very noisy. Chris up in Oregon has done the 5 cyl TDI swap, I think he's pretty happy with it.
