Wiseco Mazdaspeed 2.0 FS Turbo -16.5cc Dish Piston Shelf Stock

This listing is for a single Wiseco forged piston designed for the Mazda FS engine, commonly found in the 1993-2002 Mazda 626 and other compatible sport compact vehicles. This piston features an 83.50 mm bore and a -16.5cc dish, which is a specific design choice for certain turbo applications to help manage compression ratios. It's built from 2618 aluminum, a well-known material for its improved tensile strength in high-stress environments.

Wiseco has included several features to enhance performance and durability. The piston has precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for preventing blow-by and maintaining cylinder pressure. The crown is fully machined, and the piston also benefits from a Forced pin oiling system to ensure the wrist pin stays well-lubricated. Additionally, it comes with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly, all contributing to a more robust engine build designed to handle severe duty.

This piston is intended for serious racers and builders who need components that can withstand heavy to severe duty performance applications. Please note that this part is not CARB approved and cannot be shipped to California. It's important to check manufacturer fitment data to confirm compatibility with your specific vehicle and build.
