GSC P-D S1 2JZ-GTE Supra MK4 Turbo Cams 269/269 Billet

GSC Power Division is well-known for making serious performance parts for import engines, and their S1 camshafts for the 2JZ-GTE engine in the 1993-1998 Toyota Supra are a prime example. If you're looking to get more out of your twin-turbo Supra, these cams are designed to help you achieve that goal. They are specifically ground for the 2JZ-GTE's turbo setup, meaning they work with the factory turbochargers or similarly sized aftermarket units to improve airflow into and out of the cylinders.

These are billet camshafts, which means they start as a solid piece of steel that is then precisely machined to the desired profile. This manufacturing method results in a stronger, more durable camshaft compared to cast cams, and it allows for more aggressive and accurate lobe designs. The 269-degree intake and exhaust duration on both the intake and exhaust sides are a popular choice for a street/strip setup, offering a noticeable bump in power without requiring extreme valvetrain modifications. This profile is a good balance for making more power while still being manageable for daily driving or occasional track use.

When installing these camshafts, it's important to ensure your engine's valvetrain is in good condition. You'll want to check your valve springs and retainers to make sure they can handle the increased lift and duration. While these cams are designed to work with the stock ECU and fuel system for many applications, tuning is highly recommended to take full advantage of the improved airflow and ensure optimal engine performance and longevity. Please note that these camshafts are not CARB approved and cannot be shipped to California.
