Description Applications
The GSC Power-Division Billet Stage 3 camshaft set are manufactured specifically to fit the USDM STI and WRX with Intake only AVCS. The GSC S3 cams are designed for 750-1000 Wheel Horsepower built EJ25 engines with a rev range of 4500-9500rpms. Certain modifications are required to utilize the potential of the Stage 3 camshafts such as ported heads and supporting engine management. Upgraded valve springs are required (Do not reuse OEM); Beehive valve springs are recommended but not required. Due to the larger lobe size of the cams, the head casting will require filing for clearance.
