Wiseco BMW S54B32 3.2L 24V Turbo 87.50mm Bore 0.50 Oversize Piston Kit

When you're rebuilding the heart of your 2001-2006 BMW M3 for serious performance, especially with a turbo setup, you need pistons that can handle the stress. This Wiseco piston kit gives you six forged pistons, each with an 87.50mm bore, which is 0.50mm oversize from the factory specification. These aren't just any pistons; they're built from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of heavy and severe duty race applications.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that enhance ring seal. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown is ready for your build, and the forced pin oiling design ensures the wrist pins stay well-lubricated under high loads. This kit is designed for builders who are pushing their S54B32 engine well beyond stock limits.

This kit includes everything you need to replace the pistons in your M3's S54B32 engine. Remember that these pistons are 0.50mm oversize, so your engine block will need to be bored to match. Please note that this kit is not CARB approved and cannot be shipped to California.
