GSC P-D Subaru EJ20 JDM / Euro Spec STi S2 Cams 272/272 (Not compatible w/USA Spec Engines) Billet

If you're looking to get more out of your Subaru EJ20 JDM or Euro spec engine, especially if you're rebuilding the top end or aiming for a more aggressive powerband, these GSC Power Division STi S2 camshafts are a solid choice. These are specifically designed for the JDM and Euro versions of the EJ20 engine, so they won't work with the USA-spec engines. The 272-degree duration on both the intake and exhaust sides means you'll see a noticeable bump in performance, particularly in the mid-to-upper RPM range, making them a popular option for track-focused builds or spirited street driving.

What sets these cams apart is their billet construction. This means they start as a solid piece of steel that's machined to shape, resulting in a very strong and precise camshaft. This is important because camshafts operate under high stress and need to be incredibly accurate to ensure proper valve timing and lift. The 272/272 grind is a well-known profile that offers a good balance between increased airflow and streetability, providing improved power without making the engine too difficult to manage in daily driving conditions. Keep in mind that these are not compatible with USA-spec EJ20 engines, so double-check your engine code before ordering.

When installing these camshafts, you'll want to ensure you have the correct tools and a good understanding of valve timing. It's always a good idea to consult the manufacturer's installation instructions for the most accurate guidance. Because these cams are designed for specific engine variants, it's crucial to confirm your engine is the JDM or Euro spec EJ20 to ensure proper fitment and performance. These are a significant upgrade for enthusiasts looking to extract more power from their compatible Subaru.
