GSC Power-Division S1 cams for the VVTi Toyota Supra 2JZ-GTE. The S1 cams are designed for those running an upgraded single turbo larger than 57mm. These cams will not have bottom end losses over stock cams with larger turbo's; nothing but gains and will promote an extremely flat torque curve. Gains of 40-70whp (depending on Turbo) have been seen by simply bolting the S1 cams in and reshimming with a proper tune. Designed for a rev range of 3500-8000rpms, these cams require a single valve spring upgrade over stock. 500-1000whp camshaft set with an idle slightly rougher than stock.
