GSC P-D 3SGTE Gen 3 MR2 Turbo S3 Cams 280/280 Billet

GSC Power Division is well-known for making serious performance parts for import engines. If you're building a high-performance 3SGTE Gen 3 engine, especially for an MR2 Turbo, their S3 camshafts are a popular choice. These cams are designed to help your engine breathe better at higher RPMs, which is key for making more power when you're pushing the engine hard. They are made from billet material, meaning they start as a solid piece of steel and are precisely machined, which results in a very strong and accurate camshaft profile.

The S3 profile offers 280 degrees of duration on both the intake and exhaust sides. This means the valves stay open for a longer period, allowing more air and fuel mixture into the cylinders and more exhaust gases out. This aggressive duration is ideal for modified engines looking for a significant boost in performance, particularly in the mid to upper RPM range. Because they are billet, these cams are built to withstand the increased stress and heat found in a performance-tuned engine. They are a direct replacement for your stock camshafts, but you will need to ensure your valvetrain components can handle the increased lift and duration.

When installing these camshafts, it's important to follow the manufacturer's recommended procedure. You'll want to make sure your engine's tuning is adjusted to take full advantage of the improved airflow these cams allow. Keep in mind that these camshafts are not CARB approved and cannot be shipped to California. They are also subject to California's Prop 65 warning.
