I am planning on turning my 2004 chevy silverado 1500 ls 4.8l extended cab long bed into a 500-600hp beast. I was thinking of running a Precision PT6266 turbo or a PT6766 turbo with the 750hp universal intercooler, pw46 external wastegate, TiAl 50mm BOV, NLR AMS-500 boost controller, and possibly the Wilson 90mm throttle body. I would have custom piping bent and it would be a front mount turbo and i would change up the camshaft, injectors, etc. too. Of course i would upgrade my transmission with the monster 650hp rated upgrade kit for my 4l60e and would probably get a driveshaft out of a 2500 or somthing and mod it to fit. What do you guys think i should do differently?
