Designed for high-output builds, the GSC Power Division S2 Billet Camshafts are the go-to choice for Subaru EJ25 owners aiming for significant power gains. With a 272/272 duration, these cams are engineered to support larger turbochargers and increased boost levels, providing the high-RPM power needed for competitive driving.
These S2 cams significantly improve airflow, allowing your engine to make more power throughout the upper RPM range. The billet construction ensures maximum durability under extreme stress, preventing the wear and fatigue often associated with stock or lesser-quality cams. To achieve the best results, we recommend pairing these camshafts with upgraded valve springs and retainers to prevent valve float at high RPMs. Professional tuning is required to fully realize the potential of this aggressive cam profile. Elevate your Subaru's performance with premium components from GGCRACING.
