Wiseco 6677M87AP Toyota 2JZ-GTE Forged Piston 87.00mm Bore 9.5:1 Compression

The Wiseco 6677M87AP is a Professional Series forged racing piston engineered for the Toyota 2JZ-GTE engine, featuring an 87.00mm bore and a 9.5:1 compression ratio with a -5.3cc dish crown. Designed for serious engine builders and racers, this single piston is built to withstand the extreme cylinder pressures and combustion loads common in high-output 2JZ builds.

Wiseco's Professional Series pistons are no-expense-spared components packed with custom-level performance and durability features. Each piston is engineered, forged, and machined in the USA from 2618 aluminum alloy, a material renowned for its exceptional tensile strength and resilience under race conditions. The ArmorPlating (AP) coating on the crown provides an added layer of protection against detonation and extreme heat.

Key Features:

• 87.00mm bore diameter for precise fitment in the Toyota 2JZ-GTE
• 9.5:1 compression ratio with -5.3cc dish crown — ideal for forced induction and high-boost applications
• Forged and machined in the USA from 2618 aluminum for superior strength and durability
• ArmorPlating (AP) crown coating for enhanced detonation resistance and thermal protection
• ArmorGlide skirt coating for reduced friction, seizure resistance, and quieter operation
• Precision ring grooves with anti-detonation groove for improved ring seal
• 0.866 in. (22mm) pin diameter with forced pin oiling for reliable lubrication
• Offset wrist pin bore minimizes piston rock and reduces noise

The 6677M87AP is purpose-built for heavy to severe duty performance applications, making it a trusted choice for turbocharged 2JZ street builds, drag racing, time attack, and high-horsepower motorsports use.
