which is a better setup for a daily driver in terms of reliability and overall performance (tr224 and afr 205) or (ati procharger with 5-7 psi.) ...car is an 02 ss m6 with kooks LT, high flow cats, gmmg, lid, throttle body....please help guys.

 

Cam and head...

IMHO are'nt there some ported heads that keep up for about $600 less?

Also I think something like the TR224 114LSA+4 or better a G5X2 232/240 .595/.609 114LSA + 4

 

H/C for sure
( simply because if it is not enough! then you can slap that SC on top )
