Fresh Stock GSC Power-Division S3 Billet Camshaft Set 2002-2005 WRX

Description

Upgrade your 2002-2005 Subaru WRX with the GSC Power-Division S3 Billet Camshaft Set, engineered for high horsepower performance. These premium billet camshafts are designed specifically for the EJ205 WRX Version 5 and 6 engines, delivering power gains in the 700 WHP range and beyond. Perfect for enthusiasts seeking serious upgrades, the S3 cams unlock your engine’s true potential when paired with the right supporting mods.

Key features include billet construction for durability, compatibility with built motors and ported heads, and the need for upgraded valve springs—beehive springs recommended but not mandatory. Due to the large lobe size, slight head casting modification is required for clearance. Proper break-in procedures and high zinc oil use are essential for flat tappet cam longevity. Installation should be performed by experienced technicians to ensure optimal results.

Ideal for Subaru WRX owners pushing their builds to the next level, this camshaft set is a must-have for serious power seekers. Shop now at Subimods and enhance your Subaru’s performance with confidence.
