GSC P-D Toyota 1JZ-GTE S3 Camshafts Billet

GSC Power Division is well-known for making performance engine components, and their S3 camshafts for the Toyota 1JZ-GTE engine are a prime example of their work. If you're looking to significantly increase the airflow into and out of your engine, these camshafts are designed to help you achieve that goal. They are built from billet material, which is a strong and precise way to manufacture camshafts, ensuring durability and consistent performance for your 1JZ-GTE build.

These S3 camshafts feature a more aggressive profile compared to stock, meaning they open the valves for longer durations and lift them higher. This allows for a much greater volume of air and fuel mixture to enter the cylinders and for exhaust gases to exit more efficiently, especially at higher RPMs. The billet construction means these camshafts are made from a solid piece of steel that is precisely machined, offering a strong foundation for the advanced lobe designs that GSC Power Division has developed. This approach ensures that the camshafts can withstand the increased stresses of a performance engine.

When installing these camshafts, it's important to ensure your valvetrain is in good condition and capable of handling the increased lift and duration. You'll also want to consider supporting modifications like upgraded valve springs and retainers to get the most out of the S3 profile and ensure reliability. Because these camshafts are not CARB approved, they cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed procedures and recommended supporting components.
