Wiseco MAZDA Turbo -4cc 1.201 X 83.5 Piston Shelf Stock Kit

When you're building a serious performance engine for your Mazda Miata, especially one that's going to see turbo power and heavy use, you need pistons that can handle the stress. This kit from Wiseco includes four forged pistons, precision-machined to an 83.50 mm bore size, designed specifically for the 1.8L 16V L8 engine found in your 1994-1997 or 1999-2005 Miata.

These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, giving them improved tensile strength for demanding applications. Wiseco has included advanced features like precision ring grooves, anti-detonation grooves, and enhanced ring seal designs to ensure everything stays tight under pressure. The piston crowns are fully machined, and they come with forced pin oiling to keep the wrist pins lubricated. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, making them well-suited for heavy to severe duty builds.

This set is designed for sport compact applications and includes the necessary components for a complete piston replacement. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For the best results, always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
