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 customer’s 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.

The S2 cams are designed for those with a GT30-GT37 Turbo. No low end power is lost vs the stock cams when used with the larger turbo. The S2 cams will show gains of 40-50whp over the stock cams and in some cases more in the higher RPMS. Great for 2.0L engines revving to 9000rpms or for Stroker motors revving to 8000rpms. The S2 Cams require upgraded valve springs (check out GSC’s Chro-Molly Retainers and single valve spring kit for a perfect upgrade to your valve train). Designed for a rev range of 4000-9000 RPMS(2.0L or 3000-8000 2.2L+), 500-700whp applications. Not suggested for smaller stock appearing turbo setups.
