Power Division High Performance Billet S1 Camshafts.
GSC Power-Division is proud to release the much anticipated S-Series Camshafts for the EVO IV-VIII 4G63T Motor. With 2 different profiles S1 and S2 cams that provide unmatched gains for anyone with a stock turbo all the way to a large GT37 series turbo. GSC also offers a Custom S3 grind that is designed specifically to the customerís motor needs; available for those pushing above the S2's 700whp capabilities (please contact GSC directly).
The S1 cams are designed for those with the stock turbo up to the GT30/50Trim. These cams will not sacrifice any bottom end loss over stock cams; nothing but gains and will promote faster spooling of the upgraded turbos. Gains of 25-40whp (depending on Turbo) have been seen by simply bolting the S1 cams in. Designed for a rev range of 3000-8000rpms, these cams work well on the stock valve springs. 300-450whp camshaft.
