GSC Power-Division 2JZ-GTE Billet 2JZ-GTE S1 Camshafts
Cody Phillips Racing
GSC Power-Division billet S1 cams for the 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 on 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 bolting the S1 cams in, reshimming, and tuning. These cams require a single valve spring upgrade over stock.
