Subaru EJ20 WRX NON AVCS Camshafts

The GSC Power-Division billet S1 camshafts for the EJ205 WRX Version 5 and 6. These will not drop any low end power, but actually cause faster spool of the turbo, creating more power and torque across the entire RPM range. Good for stock turbo or up to 500 WHP upgrades. These cams require upgraded valve springs to keep everything safe at high RPM.

GSC Power-Division billet S2 camshafts for the EJ205 WRX Version 5 and 6. These cams are built to suite the high horsepower Subis. With a power range of 500 WHP and up, you need some certain mods to utilize the true potential of the S2s: built motor, with a built/ported head, and a good engine management system. Upgraded valve springs are required; beehive valve springs are recommended, but not required. An upgraded single spring kit will do the job under 8000 RPM. 

GSC Power-Division billet S3 camshafts for the EJ205 WRX Version 5 and 6. These cams are built to suit the high horsepower Subis. With a power range of 700 WHP and up, you need some certain mods to utilize the true potential of the S3s: built motor, with a built/ported head, and a good engine management system. Upgraded valve springs are required; beehive valve springs are recommended, but not required.
