GSC Power-Division Billet S3 Camshaft Set for R35 GTR (VR38DETT)
The GSC7045 Forged Billet S3 is GSC Power-Division's camshaft set for the VR38-powered GT-R. The billet cores are proprietary and made in house at GSC, producing cams that are stronger and lighter with additional fatigue and wear resistance. CNC machining and grinding deliver accurate, repeatable camshafts, with precision gun drilling down the center of the cam for oil delivery and weight reduction.
The 7045S3 requires GSC 5054 Beehive valve springs and lightweight titanium retainers. This combination will keep the valvetrain happy up to 9,800 RPM at 60 PSI of boost. GSC designed the valve springs and retainers specifically for the high horsepower VR38DETT, using different intake and exhaust retainers to maintain proper spring seat pressure.
