GSC P-D S3 2JZ-GTE Supra MK4 Turbo Cams 290/290 Billet

These GSC Power Division S3 camshafts are built from solid billet for your 1993-1998 Toyota Supra 2JZ-GTE engine. With a 290-degree duration on both the intake and exhaust sides, these cams are specifically designed for turbo applications where increased airflow and improved cylinder filling are key to making more power. The billet construction means they start as a solid piece of steel, which is then precisely machined to GSC's specifications. This method offers a strong foundation for the aggressive profiles needed for high-performance turbocharging, ensuring reliability under demanding conditions.

The 290-degree duration is a popular choice for enthusiasts looking to significantly boost their turbo 2JZ-GTE's performance. This duration allows the valves to stay open longer, letting more air and fuel into the cylinder during the intake stroke and more exhaust out during the exhaust stroke. This improved volumetric efficiency is crucial for turbo engines, as it helps the turbocharger spool more effectively and allows the engine to breathe better at higher RPMs. The S3 profile is a well-known option for those building a serious performance engine, offering a noticeable change in power delivery compared to stock or milder aftermarket cams.

When installing these camshafts, it's important to follow the manufacturer's recommended procedures, as precise timing is critical for optimal performance and engine health. Because these are performance camshafts, they are intended for use in modified engines and are not CARB approved, meaning they cannot be legally shipped to California. Ensure your engine build is set up to take advantage of this level of camshaft performance.
