GSC P-D Toyota 2JZ-GTE VVTI (JDM Only) S2 Cams 274/274 Billet

If you're building a high-performance Toyota 2JZ-GTE VVTI engine, especially one intended for serious track use or drag racing, a camshaft upgrade is a critical step to unlock more power. These GSC Power Division S2 camshafts are designed to significantly improve airflow into and out of your cylinders, making them a popular choice for enthusiasts looking to push their JDM-spec 2JZ-GTE beyond its factory limits.

Crafted from solid billet steel, these camshafts are built to withstand the increased stress and heat found in modified performance engines. The S2 profile features a 274-degree duration on both the intake and exhaust sides. This aggressive profile is optimized for engines that have other supporting modifications, like upgraded turbochargers, intake manifolds, and exhaust systems, allowing for a substantial increase in airflow at higher RPMs. The precise lobe separation and lift figures are a result of GSC's extensive testing and development, ensuring that these cams work harmoniously with the VVTI system to deliver improved performance across a broader powerband than older, non-VVTI profiles.

When installing these camshafts, it's important to note that they are intended for JDM-spec 2JZ-GTE VVTI engines only and are not CARB approved, meaning they cannot be legally shipped to California. Proper tuning will be essential to take full advantage of the S2 profile and ensure the engine runs smoothly and reliably. Consider pairing these with upgraded valve springs and retainers to handle the increased lift and duration safely.
