Wiseco BMW S50B30 3.0L 24V Turbo Bore (86.5mm) - Size (+.50) - CR (12.0) Hich Compression Pistons

Wiseco is well-known for making strong internal engine components, and these forged pistons for the BMW S50B30 engine are no exception. If you're rebuilding the top end of your 3.0L 24-valve S50 engine, especially for a turbo application, these pistons are built to handle the demands. They feature a bore size of 86.5mm, which is a 0.50mm oversize, and a compression ratio of 12.0:1, making them suitable for builds aiming for significant power gains.

These pistons are forged from high-strength aluminum, a process that creates a denser, more durable material compared to cast pistons. This makes them resistant to the high pressures and temperatures generated in performance engines, particularly when boosted with a turbocharger. The 12.0:1 compression ratio is a notable step up from stock, designed to work effectively with forced induction to maximize power output. It's important to note that these pistons are not CARB approved and cannot be shipped to California.

When undertaking an engine rebuild with these pistons, ensure you consult with your engine builder or refer to Wiseco's installation guidelines. Proper ring gap, piston-to-wall clearance, and balancing are critical for longevity and performance. This set is designed for the S50B30 engine, a popular choice for BMW performance enthusiasts looking to enhance their vehicle's power and reliability.
