Wiseco BMW S50B32 3.2L 24V Turbo Bore (87.0mm) - Size (+.60) - CR (11.3) Std Compression Pistons

If you're rebuilding the engine in your 1996-1999 BMW M3 for serious performance, especially with forced induction, these Wiseco forged pistons are a solid choice. They're built to handle the demands of heavy to severe duty race applications, giving you the confidence to push your engine further. The 87.0mm bore size is specific to the S50B32 engine, and these come with a standard compression ratio of 11.3:1, suitable for many turbo builds.

Wiseco makes these pistons in the USA from 2618 aluminum, which is known for its improved tensile strength, making them well-suited for high-stress environments. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown ensures accuracy, and they also include forced pin oiling to keep the wrist pins lubricated. Plus, they come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly.

This set includes six pistons, enough for your entire S50B32 engine. Keep in mind these pistons are not CARB approved and cannot be shipped to California. For detailed installation instructions and any specific hardware requirements, always refer to the manufacturer's guidelines.
