Description

GSC Power-Division S3 camshafts for the Inlet AVCS EJ25. These cams are built to suit the highest horsepower drag Subies. With a power range of 750-1000WHP and a rev range of 4500-9500rpms, you need some certain mods to utilize the true potential of the S3s. Built motor, with a built/ported head (clearanced for lift), and a standalone engine management system. Upgraded valve springs are required; Beehive valve springs are recommended but not required.

Due to the lobe size, head castings will need to be filled down slightly for clearance.
