GSC Power Division S1 Billet Performance Camshaft Kit EJ20/205 Non VVT 1999+

GSC Power-Division billet S1 camshafts for the EJ205 WRX Version 5 and 6.

They do not lose any low-end power; the turbo spools faster, and power and torque increase across the entire rev range. Suitable for the stock turbo or builds up to 500 WHP.

Upgraded valve springs are required to keep everything safe at high rpm.
