when my 6.2 goes out, ill end going with a 6.5. i noticed there wasnt as aftermarket turbo upgrade kits for them. on the banks site they said that the banks turbo is better than any of the 6.5 turbos so why not put the 6.2 banks kit on the 6.5, is it doable? what about other turbos being made to fit on 6.5's? what the most usable hp/tq people have been able to get out of a 6.5?
