What is the compression height and pin diameter for these pistons?

These Wiseco pistons have a compression height of 31.95 mm and a pin diameter of 0.787 inches. This ensures proper fitment and geometry within the 1.6L 16V B6 engine for the specified Mazda Miata models.

Are these pistons suitable for a street-driven car?

While built with extreme durability in mind, these pistons are designed for heavy to severe duty race builds. They feature advanced materials and coatings for high-stress environments. It's recommended to consult with a performance engine builder to ensure they align with your specific build goals.

What does the ArmorGlide skirt coating do?

The ArmorGlide skirt coating on these Wiseco pistons is designed to reduce friction between the piston skirt and cylinder wall. This also helps to resist seizure under high temperatures and contributes to quieter operation of the engine.

Product Details

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and heavy-duty performance builds. They feature a -13cc dish and a 78.5mm bore, designed specifically for the 1.6L 16V B6 engine found in the 1990-1993 Mazda Miata. This set includes four pistons, each meticulously machined in the USA to ensure precise fitment and optimal performance.

Wiseco's Professional Series pistons come packed with features aimed at durability and improved performance. You'll find precision ring grooves, anti-detonation grooves, and additional features for better ring seal. The pistons also include forced pin oiling to keep things well-lubricated under high stress. A unique ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation, all while the fully machined crown ensures a clean combustion chamber profile.

This piston set is designed and built to withstand heavy to severe duty performance applications. While these pistons are a significant upgrade for a performance build, please note they are not CARB approved and cannot be shipped to California. For a complete rebuild, ensure you have all necessary supporting components and refer to manufacturer instructions for proper installation.
