GSC P-D Subaru EJ25 Single AVCS (w/RH Intake Oil Pump Scavenger Drive) 264/264 S1 Billet Camshaft

This is the GSC Power Division 7024S1 billet camshaft, specifically designed for Subaru EJ25 engines equipped with Single AVCS and the right-hand intake oil pump scavenger drive. If you're building a performance EJ25 and need a camshaft that can handle increased airflow and provide a noticeable bump in power, this is a solid option. The 264/264 duration and S1 grind profile are chosen to work well with naturally aspirated or lightly modified setups, offering improved performance without sacrificing too much drivability.

What sets this camshaft apart is its billet construction, meaning it's machined from a solid piece of steel. This makes it incredibly strong and resistant to flexing or wear, even under high RPMs and increased spring pressures. The inclusion of the right-hand intake oil pump scavenger drive is a notable detail for EJ25 builds, as it helps ensure consistent oil supply to the intake camshaft, which is crucial for the AVCS system to function correctly and reliably, especially when pushing the engine hard. The 264 degree intake and exhaust duration on both cams means you'll see a good increase in both low-end and mid-range power, making it a versatile choice for street or track use.

When installing these camshafts, it's important to use upgraded valve springs that match the camshaft's profile to ensure proper valve control at higher engine speeds. You'll also want to ensure your engine's oiling system is in top condition. Because this camshaft is not CARB approved, it cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding valve spring requirements and break-in procedures.
