Wiseco MAZDA Turbo -13cc 1.258 X 79MM Piston Shelf Stock Kit

Wiseco is well-known for making strong internal engine components, especially for performance applications. If you're building a serious engine for your 1990-1993 Mazda Miata, especially one intended for forced induction, this Professional Series piston set is designed to handle the extra stress. These aren't your average pistons; they're built from the ground up for heavy to severe duty use, meaning they can take a beating and keep performing when you push your engine hard.

Each piston in this set is forged and machined right here in the USA from 2618 aluminum, which gives them improved tensile strength over standard cast pistons. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal and prevent detonation. They also come with an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. The fully machined crown and forced pin oiling are details that show these pistons are made for demanding performance builds.

This kit includes four pistons, each with a 79.00 mm bore and a -13cc dish to help achieve your desired compression ratio, especially when adding a turbocharger. The kit also includes premium rings to ensure a good seal. Remember, these pistons are not CARB approved and cannot be shipped to California. If you're serious about building a reliable, high-performance engine for your Miata, this Wiseco piston set is a solid choice.
