Wiseco MAZDA Turbo -4cc 1.201 X 84.5 Piston Shelf Stock

If you're building a performance engine for your 1999-2005 Mazda Miata, especially for turbo applications, these Wiseco pistons are a solid choice. They're designed to handle the extra stress and heat that come with boosted performance, making them suitable for heavy to severe duty race builds. Wiseco machines these pistons from 2618 aluminum right here in the USA, which gives them improved tensile strength to resist deformation under high cylinder pressures.

You'll find precision ring grooves on these pistons, along with anti-detonation grooves and other features that help improve ring seal. This is crucial for keeping combustion pressure where it belongs and preventing blow-by. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, resist seizure if things get hot, and makes for quieter operation. The fully machined crown ensures accuracy for proper combustion chamber volume.

These pistons feature forced pin oiling, which means they get a direct supply of oil to the wrist pin for better lubrication and longevity. Keep in mind that these are not CARB approved and cannot be shipped to California. If you're pushing your Miata's engine hard, these pistons are built to keep up.
