K641M90

Overview:

The Wiseco Professional Series forged pistons are precision-engineered components designed for serious racers and high-performance builders. Crafted to handle heavy to severe duty race applications, these pistons deliver exceptional strength and durability for your Scion tC equipped with the 2AZ-FE engine. Whether you are upgrading for track use or building a robust performance engine, Wiseco’s Professional Series pistons provide the reliability and performance you need to push your build beyond factory limits.

Manufactured in the USA from premium 2618 aluminum alloy, these pistons offer superior tensile strength and are supplied as a complete set of four, including premium rings. They are ideal for sport compact enthusiasts seeking enhanced engine durability and consistent performance under demanding conditions.

Key Features:

These pistons incorporate advanced design and manufacturing technologies to ensure optimal performance and longevity:

• Forged from high-strength 2618 aluminum alloy for improved tensile strength and durability.
• Precision-machined ring grooves and an anti-detonation groove to enhance ring seal and reduce the risk of detonation.
• ArmorGlide skirt coating reduces friction, resists seizure, and promotes quieter piston operation.
• Fully machined crown design optimized for performance and combustion efficiency.
• Forced pin oiling system to improve wrist pin lubrication and durability under high-stress conditions.
• Designed specifically for the Toyota 2AZ-FE engine with a 90.00 mm bore and 33.25 mm compression height.
• Includes premium piston rings engineered for severe duty race builds.
• Set of four pistons tailored for Scion tC Base (2005–2010) and Spec (2007–2008) models.

Construction & Design:

Wiseco’s Professional Series pistons are forged and machined in the USA using 2618 aluminum, a material known for its excellent strength and fatigue resistance in high-performance environments. The pistons feature precision ring grooves and an anti-detonation groove that improve ring sealing and help prevent pre-ignition issues. The ArmorGlide skirt coating minimizes friction and wear, contributing to smoother engine operation and extended component life.

The fully machined crown is designed to optimize combustion chamber dynamics, while the forced pin oiling system ensures consistent lubrication of the wrist pin, reducing wear during high RPM and heavy load conditions. These design elements combine to provide a piston capable of withstanding the rigors of racing and severe duty applications.

Installation & Fitment:

This piston set is engineered as a direct replacement for the factory pistons in the Scion tC equipped with the 2AZ-FE engine. The dimensions, including a 90.00 mm bore and 33.25 mm compression height, match OEM specifications to ensure proper fitment and compatibility.

Installation requires professional engine assembly knowledge and appropriate machining and balancing to ensure optimal performance and reliability. These pistons are intended for race or high-performance builds and may require supporting modifications to the engine and tuning for best results.
