2.3 stroker 4g63 sounds way better than even the best 3800
the 4g63 is capable of 600+ hp on stock bottom end.
gvr4 is slower stock but hp per dollar is better than a gp.
if im not mistaken they run 11psi stock idk bout the 16g. is that the big or small 16g? also does it already have the gm mass air translater?
kudos on the ride. i personally wouldnt drive it but i like the motor, used to drive a talon tsi awd. dsmparts.com is your best friend btw
