1JZ-GTE VVTi S1 Camshafts - Billet by GSC Power-Division
These cams are best for 54mm to 67mm turbos, 350hp to 650hp. The S1 cams are designed for those running an upgraded turbo. 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, and we recommend valve spring upgrade over stock. Idle will be very close to stock.
