Wiseco BMW M52B28 2.8L 24V Turbo 85.00MM Bore +1.00 Oversized 8.0:1 CR Pistons

If you're building a high-performance BMW M52B28 engine, especially for turbo applications, these Wiseco pistons are a solid choice. They're designed to handle the demands of serious racing and heavy-duty builds. This set is for the M52B28 engine, with a bore of 85.00mm, and they are +1.00 oversized, meaning they are 0.040 inches larger than the standard bore size. The compression ratio comes in at 8.0:1, which is ideal for boosted engines where you need to control detonation.

Wiseco makes these pistons from 2618 aluminum, a material known for its strength and durability, which is crucial when you're pushing an engine hard. They feature precision ring grooves, an anti-detonation groove, and other features to ensure a good seal and prevent issues under high pressure. You also get an ArmorGlide skirt coating, which helps reduce friction, makes the engine run quieter, and resists seizure. The crown is fully machined, and they include forced pin oiling for better lubrication.

This set includes six pistons, rings, and pins, ready for installation. Keep in mind these are not CARB approved and cannot be shipped to California. For a build like this, you'll want to ensure you have all the necessary supporting components and follow the manufacturer's installation instructions carefully.
