Product Details
GSC Power Division is known for making well-built performance engine components, and these S3 billet camshafts for the 2002-2005 Subaru WRX EJ205 engine are a prime example. If you're looking to get more out of your WRX's engine, these cams are designed to improve airflow and performance, especially when paired with other modifications.
These camshafts are CNC machined from solid billet steel, which is a strong foundation for precise lobe profiles. The S3 grind features 280 degrees of duration on both the intake and exhaust sides. This means the valves stay open longer, allowing more air and fuel into the cylinder and more exhaust out. This increased volumetric efficiency is key to making more power, particularly in the mid to upper RPM range. They are designed as a direct replacement for your stock camshafts, meaning they fit into the factory cam gears and valve train components, simplifying installation. While they are a significant upgrade, they are intended to work with the stock valve springs and retainers, making them a popular choice for builds that don't require a full race setup.
Keep in mind that these camshafts are not CARB approved and cannot be shipped to California. They are also subject to California's Proposition 65 warning. For optimal performance and reliability, it's always recommended to consult the manufacturer's installation guide or a qualified mechanic for proper setup and tuning, especially when making significant engine modifications.
