GSC Power-Division billet S2 camshafts for the EJ20 JDM/EURO 2.0L STi. These cams are built to suit 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.
Due to the lobe size, head castings will need to be filed down slightly for clearance - Please check during install
