Billet S2 Camshaft Set – Nissan GT-R VR38DETT - GSC7045S2
Billet S2 Cams for High-Output VR38DETT Builds
The GSC7045S2 Billet S2 Camshaft Set is the latest precision-engineered upgrade for the VR38DETT-powered Nissan GT-R. These cams are the result of extensive development and testing, built from proprietary billet cores produced in-house at GSC Power-Division.
Designed to be lighter and stronger than OEM, each camshaft features enhanced fatigue and wear resistance. CNC machining and grinding ensure exceptional accuracy and repeatability, while precision gun-drilling through the cam center improves oil flow and reduces rotating mass. Whether you're building a mild street car or a 1500+ HP stroker, these cams deliver the durability and performance GSC is known for.
Required Components
To run the GSC7045S2 cams, you’ll need the GSC5068 Conical Valve Springs and lightweight titanium retainers. These components are engineered to handle up to 9800 RPM and 60 psi of boost, with intake and exhaust retainers optimized to maintain proper spring seat pressure in high-horsepower VR38 applications.
