Wiseco BMW S54B32 3.2L 24V Turbo 87mm Bore 8.8:1 CR Piston Kit

Wiseco is well-known for making strong, reliable forged pistons that can handle serious abuse. If you're building a high-performance engine, especially for forced induction, their Professional Series pistons are a solid choice. This particular kit is made for the BMW S54B32 engine found in the 2001-2006 M3, and it's designed to take on heavy to severe duty race applications.

These pistons are forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength. They feature precision ring grooves, an anti-detonation groove, and other features to help seal the rings better, which is crucial for turbocharging. The crown is also fully machined, and they come with forced pin oiling to keep things well-lubricated. Plus, they have an ArmorGlide skirt coating that helps reduce friction and noise, and makes them more resistant to seizing.

This kit includes a set of six pistons, each with an 87mm bore and a 8.8:1 compression ratio, making them ideal for turbo builds. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. You'll want to refer to the manufacturer's installation instructions for specific details on fitting these pistons to your engine.
