GSC Power-Division Billet S3 Camshafts for the 2008-19 Subaru STI EJ257 with Dual AVCS are built to suit high horsepower drag Subaru's. With a power range of 750-1000 WHP and a rev range of 4500-9500 RPMs, you need certain mods to utilize the true potential of the S3s: built motor, with a built/ported head (clearance for lift), and an engine management solution. Upgraded valve springs are required; GSC beehive valve springs are recommended but not required.

GSC Install Recommendations:
  • 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
  • Check AVCS advance during install - must be done by experienced engine builder
