GSC P-D Subaru EJ25 Single AVCS (w/RH Intake Oil Pump Scavenger Drive) S2 Cams 272/272 Billet

This package includes a set of GSC Power Division S2 camshafts specifically for Subaru EJ25 engines equipped with Single AVCS and the right-hand intake oil pump scavenger drive. These are billet camshafts, meaning they are machined from a solid piece of steel for improved strength and precision. The 272-degree duration on both the intake and exhaust sides are designed to work together to increase airflow into and out of your engine, which can lead to improved performance, especially when you're pushing your engine harder.

GSC Power Division is known for making well-built engine components, and these S2 cams are a popular choice for Subaru enthusiasts looking to get more out of their EJ25. The 272 duration is a moderate grind that offers a noticeable bump in power without making the engine too difficult to manage for daily driving. They are designed to be a direct replacement for your stock camshafts, though it's always recommended to consult the manufacturer's installation guide for specific details regarding valve spring requirements and other potential modifications needed for optimal performance. Because these are billet cams, they offer a more consistent profile and greater durability compared to cast camshafts.

When installing these camshafts, pay close attention to the intake oil pump scavenger drive, as this specific grind includes provisions for it. This is a critical component for ensuring proper oil flow to the AVCS system. While these cams are designed to work with the factory AVCS system, it's always a good idea to have your ECU tuned after installation to take full advantage of the improved airflow and ensure everything is running smoothly. Remember, these camshafts are not CARB approved and cannot be shipped to California.
