GSC Power-Division Toyota Supra 2JZ-GTE MKIV Turbo S1
GSC Power-Division 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;
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. Designed for a rev range of 3500-8000rpms,
these cams require a single valve spring upgrade over stock. 550-750whp
camshaft set with an idle slightly rougher than stock.
