I think with cams you'll notice the biggest gainsfor. I;ve always liked smaller turbos for quicker spool then larger turbos for more horsepower.

It looks like its about a 1500 dollar upgade if you find the right places and do a lot of the work yourself. The Brian Crower Valve Sping and TI Retainer kit is $350 bucks online and the Brian Crower 264 degree camshafts are 620. The valves are about 220 each side, intake and exhaust. Or if you want it all done ahead of time the head is 4k.
All in all, it will help your motor breath better. Just wondering, are you running 2.5" piping through the whole intake piping setup?

Devin LeBlanc;1888901 said:On stock head, cams, and valves with no port work at all. Just valve springs and retainers I made 600WHP and 560tq At 28 PSI on a T3 adapted stock cast manifold with a 67mm.
