Description
GSC Power-Division 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 500WHP(GT35R) upgrades. These cams require upgraded valve springs to keep everything safe at high rpm.
Due to the lobe size, head castings will need to be filled down slightly for clearance.
