GSC P-D Subaru EJ20 JDM / Euro Spec STi S1 Cams 268/266 (Not compatible w/USA Spec Engines) Billet

If you're looking to get more out of your Subaru EJ20 JDM or Euro spec engine, these GSC Power Division S1 camshafts are a solid choice. Designed specifically for the EJ20, these cams offer a noticeable bump in performance over stock, making them a popular upgrade for enthusiasts who want to extract more power from their engine. It's important to note that these are not compatible with USA spec EJ20 engines, so double-check your engine code before ordering.

These S1 cams feature a 268-degree intake duration and a 266-degree exhaust duration, with a lift of 10.7mm on the intake and 10.0mm on the exhaust. This updated profile is ground on a billet core, which is a strong foundation for high-performance camshafts. The billet construction means they are machined from a solid piece of steel, offering excellent durability and stability, especially when you start pushing your engine harder. This makes them well-suited for builds aiming for improved throttle response and a broader powerband.

When installing these camshafts, you'll want to ensure you have the proper tools and knowledge for a camshaft swap. It's also a good time to inspect your valve springs and retainers to make sure they can handle the increased lift and potential for higher RPMs. Remember, these camshafts are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for the most accurate guidance.
