GSC Power-Division Toyota 2JZ VVTi - Billet S1 Camshafts GSC7030S1

Description

GSC Power-Division Toyota 2JZ VVTi - Billet S1 Camshafts. 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 turbos; nothing but gains, and will promote an extremely flat torque curve. Gains of 40-70 WHP (depending on turbo) have been seen by simply bolting the S1 cams in and reshimming with a proper tune. These cams require a single valve spring upgrade over stock. The billet S1 cams are designed for a rev range of 3500-8000 RPM. Ideal of 500-1000 wheel horse power camshaft set. Idles slightly rougher than stock.
