GSC P-D BMW B58 Gen 1.5 S1 Camshafts 268/270 Billet w/Intake Trigger (Use w/Upgraded Turbo)

If you're building a high-performance BMW B58 engine and planning to run an upgraded turbocharger, a camshaft upgrade is a critical step to unlock more power. These GSC Power Division S1 camshafts are designed specifically for the B58 Gen 1.5 engine to work with those more powerful turbo setups. They feature a 268-degree intake duration and a 270-degree exhaust duration, which helps keep the valves open longer to allow more air and fuel into the cylinders and more exhaust out. This improved breathing is essential when you're pushing more boost from a larger turbo.

These camshafts are made from a solid billet core, meaning they are machined from a single piece of steel. This construction method is strong and durable, ensuring they can handle the increased stress of a performance engine. They also include an intake trigger, which is important for the engine's computer to accurately track camshaft position for proper timing. Keep in mind that these camshafts are intended for use with upgraded turbochargers; they may not offer significant benefits or could even cause issues if used with a stock turbo. Installation will require professional knowledge of engine timing and component replacement.

Because these camshafts are designed for significant airflow improvements, they are not CARB approved and cannot be shipped to California. Ensure your engine build plans include supporting modifications for these camshafts to achieve their full potential.
