Wiseco BMW M50B25 Single Vanos 2.5L 24V Turbo 84.5mm Bore 0.50 Over Size 8.8:1 CR Piston Set

If you're building a serious performance engine for your BMW M50B25 Single Vanos 2.5L 24V turbo, this set of Wiseco forged pistons is built to handle the stress. These aren't your average pistons; they're designed for heavy to severe duty race applications where reliability under extreme conditions is critical. The pistons are forged and machined right here in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is essential when you're pushing significant boost.

Wiseco has packed these pistons with features to ensure they perform and last. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is key for both power and engine longevity. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and keep operation quieter. The fully machined crown is ready for your build, and forced pin oiling ensures the wrist pins stay well-lubricated under high loads.

This set includes six pistons, each with an 84.5mm bore and a 0.50" oversize. They are designed to achieve an 8.8:1 compression ratio, making them a solid choice for turbo builds. Remember, these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
