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, re-shimming, and tuning. These cams require a single valve spring upgrade over stock.
  • Designed for a rev range of 3500-8000 RPMs
  • 500-1000 WHP camshaft set
  • Idle slightly rougher than stock
