What is the main benefit of the 272/272 duration on these camshafts?

The 272-degree intake and exhaust duration means the valves stay open longer during each engine cycle. This allows for increased airflow into and out of the cylinders, which can lead to improved power and torque, especially in modified engines.

Are these camshafts compatible with all EJ205 engines?

These S2 camshafts are specifically designed for the EJ205 engine found in the 2002-2005 Subaru Impreza WRX and the 2005 Saab 9-2X. Fitment for other engine variants or model years is not covered by this part.

What does 'billet' construction mean for these camshafts?

Billet construction means the camshaft is machined from a solid block of metal. This results in a very strong and well-built component that is less prone to flexing or failure under high stress compared to cast camshafts.

Product Details

GSC Power Division is well-known for making performance engine components, and their S2 camshafts for the 2002-2005 Subaru Impreza WRX with the EJ205 engine are a prime example. If you're looking to get more out of your engine, these cams are designed to increase airflow and improve performance, especially when you're pushing the engine harder.

These camshafts are made from billet material, which is a strong and well-built foundation for performance. The S2 grind features a 272-degree intake and 272-degree exhaust duration. This means the valves stay open for a longer period during each cycle, allowing more air and fuel mixture into the cylinders and more exhaust gases out. This setup is popular for builds aiming for a noticeable improvement in power and torque across a broader RPM range compared to stock cams, and they pair well with other engine modifications for a more complete performance package.

When installing these, remember they are a performance upgrade and may require adjustments to your engine management system to get the most benefit. Also, please note that these camshafts are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and setup.
