GSC Power-Division S3 Billet Camshaft Set 2002-2005 WRX

GSC Power-Division billet S3 camshafts for the EJ205 WRX Version 5 and 6. These cams are built to suit the high horsepower Subys. 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.

• Check Pictures for cam placement. Long nose = Left Side, short nose = Right Side
• Due to the lobe size, head castings will need to be filed down slightly for clearance - Please check during install
• Proper break in and running high zinc oil is a must on flat tappet engines
• Must be installed by an experienced technician
