GSC Power-Division S1 cams for the Nissan SR20 S13/S14 non Variable engine. The S1 cams are designed for those running an upgraded turbo such as a GT25R to a GT3076. These cams will not have bottom end losses over stock cams; nothing but gains and will promote an extremly flat torque curve.
Gains of 30-50whp (depending on Turbo) have been seen by simply bolting the S1 cams in and reshimming. Designed for a rev range of 3000-8000rpms, these cams require a single valve spring upgrade over stock. 300-500whp camshaft set with an idle slightly ruffer than stock.
