Description

GSC Power-Division S1 camshafts for the EJ25 Inlet AVCS. 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. Upgraded valve springs are required; Beehive valve springs are recommended but not required.

Due to the lobe size, head castings will need to be filled down slightly for clearance.
