GSC P-D BMW B58 Gen 1.5 S2 Camshafts 278/274 Billet w/Intake Trigger (Use w/Upgraded Turbo)

This package includes a set of GSC Power Division BMW B58 Gen 1.5 S2 camshafts, specifically designed for use with upgraded turbochargers. These are billet camshafts featuring a 278-degree intake duration and a 274-degree exhaust duration, with an integrated intake trigger for the factory cam position sensor. They are intended to work with the factory valve springs and retainers, making them a direct replacement for your stock camshafts, though professional installation is recommended.

The S2 profile is GSC's popular choice for builds that have moved beyond stock turbochargers. The increased lift and duration compared to stock help the engine breathe more freely, allowing the upgraded turbo to spool faster and make more power. The billet construction means these camshafts are machined from a solid piece of steel, ensuring strength and durability under high stress. The intake trigger is a notable detail, as it means you won't need to modify or replace your factory sensor setup, simplifying the installation process. These camshafts are designed to work with the factory valve train, which can save on additional parts costs for your build.

It's important to note that these camshafts are not CARB approved and cannot be shipped to California. For optimal performance and reliability, it is highly recommended to pair these camshafts with a professional engine tune that accounts for the increased airflow. If you're building a B58 engine with an upgraded turbo and looking to maximize its potential, these S2 camshafts from GSC Power Division are a well-regarded option.
