Wiseco MAZDA Turbo -13cc 1.258 X 79.5MM Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in your 1990-1993 Mazda Miata's 1.6L B6 engine. The -13cc dish volume and 79.5mm bore size are specific choices for boosted applications, aiming to achieve a desired compression ratio for turbocharging. Wiseco machines these pistons in the USA, ensuring precision in every detail, from the anti-detonation grooves to the fully machined crown.

Beyond the strong aluminum construction, these pistons feature an ArmorGlide skirt coating. This coating helps reduce friction and noise, while also resisting seizure, which is crucial for longevity under high stress. The design also includes forced pin oiling to keep the wrist pins properly lubricated, and precision ring grooves with features for improved ring seal. These are intended for heavy to severe duty race builds where durability and performance are paramount.

This kit includes a set of four pistons, each with a 31.95mm compression height and a 0.787 inch pin diameter. Please note that this kit is not CARB approved and cannot be shipped to California. For optimal installation and performance, refer to Wiseco's recommended build specifications.
