Manley Performance Piston

2017–2020 Toyota 86 / 2013–2020 Subaru BRZ / 2013–2016 Scion FR-S

632600CEB-1

Overview:

The Manley Performance Piston is a high-quality forged piston designed specifically for the Toyota 86, Subaru BRZ, and Scion FR-S models within their respective year ranges. Engineered for enthusiasts and professional engine builders alike, these pistons deliver superior strength, durability, and performance for naturally aspirated or mildly tuned engines.

Built to withstand the rigors of spirited driving and track use, these pistons help improve engine reliability and power output while maintaining excellent compatibility with factory components. Whether you are upgrading your engine for enhanced performance or rebuilding for longevity, Manley’s pistons provide a trusted foundation for your build.

Key Features:

Manley Performance Pistons incorporate advanced materials and precision engineering to ensure optimal performance and durability. Key features include:

• 2618 Alloy Forgings: Manufactured from domestic 2618 alloy, these pistons offer superior strength and fatigue resistance compared to standard cast pistons.
• Chrome Moly Wrist Pins: Equipped with premium Chrome Moly wrist pins for enhanced durability; select models offer optional upgrades to 9310 or Turbo Tuff/DLC wrist pins for even greater strength.
• Exacting Ring Lands and Grooves: Precision-machined ring lands and grooves improve ring seal, reducing blow-by and increasing engine efficiency and power.
• Cam and Barrel Skirt Profiles: Designed with proven cam and barrel skirt profiles that maximize power output while minimizing wear on cylinder walls.
• Moly Skirt Coatings: Select part numbers feature molybdenum coatings on the piston skirts to reduce friction and improve longevity.
• Unique Fixturing: Manley’s patented fixturing process allows skirt turning and ring groove machining in a single operation, ensuring perfect ring groove to skirt squareness for optimal ring performance.
• Compression Ratio: Designed with a 10:1 compression ratio and an 11.4cc dish volume, ideal for maintaining factory-like combustion characteristics while supporting performance upgrades.
• Bore Size: 86mm standard bore size, matching factory specifications for direct fitment without machining.

Construction & Design:

These pistons are crafted using advanced forging techniques with 2618 aluminum alloy, known for its excellent strength-to-weight ratio and thermal conductivity. The forging process enhances the piston’s structural integrity, making it highly resistant to the stresses of high-performance operation.

The cam and barrel skirt profiles are carefully engineered to reduce friction and wear on the cylinder walls, contributing to longer engine life and smoother operation. Additionally, the moly skirt coatings on select pistons further reduce friction, improving efficiency and reducing heat buildup.

Manley’s unique fixturing technology ensures that each piston’s ring grooves are perfectly squared to the skirt, which is critical for maintaining ring seal and preventing premature ring wear or failure.

Installation & Fitment:

This piston is designed as a direct replacement for the factory pistons in the specified Toyota 86, Subaru BRZ, and Scion FR-S models. It fits the standard 86mm bore size and maintains the factory compression ratio, allowing for straightforward installation during engine rebuilds or upgrades.

No special modifications to the engine block or cylinder walls are required, making it an ideal choice for performance enthusiasts seeking reliable, bolt-in upgrades. Proper engine assembly and balancing are recommended to maximize performance and durability.

What's Included:

• Single Manley Performance Forged Piston (Platinum Series)
• Chrome Moly Wrist Pin
• Retaining clips (if applicable)
• Packaging and documentation

Ideal For:
