Key Features:

Wiseco’s Professional Series pistons incorporate advanced design and manufacturing techniques to meet the needs of competitive motorsports and high-performance builds:

• Forged from premium 2618 aluminum alloy, providing superior tensile strength and durability compared to cast pistons.
• Precision-machined ring grooves and an anti-detonation groove enhance ring seal and reduce the risk of detonation.
• ArmorGlide skirt coating reduces friction, resists seizure, and promotes quieter piston operation.
• Fully machined crown with a -29cc reverse dome shelf design optimized for the 2AZ-FE combustion chamber.
• Forced pin oiling system improves lubrication and reduces wear on the wrist pin and piston pin bore.
• Compression height of 33.25 mm and pin diameter of 0.866 inches ensure proper fitment and compatibility with stock connecting rods.
• Designed and manufactured in the USA to strict quality standards for consistent performance and reliability.

Construction & Design:

Each piston is forged from 2618 aluminum, a high-strength alloy known for its excellent fatigue resistance and thermal stability under racing conditions. The forging process enhances grain structure, resulting in a piston that can endure extreme combustion pressures and temperatures.

The ArmorGlide skirt coating minimizes friction between the piston and cylinder wall, reducing wear and improving efficiency. The precision-machined ring grooves and anti-detonation groove help maintain optimal ring seal, which is critical for power and durability in high-performance engines.

The reverse dome shelf design with a -29cc volume is tailored to the Scion tC’s 2AZ-FE engine, optimizing compression ratio and combustion characteristics for improved power delivery and efficiency.

Installation & Fitment:

This Wiseco Professional Series piston is a direct fit replacement for Scion tC models from 2005 through 2010 equipped with the 2AZ-FE engine. It is designed to work with stock connecting rods and standard bore size of 89.50 mm, making installation straightforward for experienced engine builders.

No modifications to the engine block or connecting rods are typically required when upgrading to this piston, but professional installation and proper engine assembly practices are recommended to ensure optimal performance and reliability.
