Manley Performance Platinum Series Piston Set
2013–2020 Subaru BRZ / 2017–2020 Toyota 86 / 2013–2016 Scion FR-S FA20 Engine
632601C-4
Overview:
The Manley Performance Platinum Series piston set is engineered specifically for the FA20 engine found in the Subaru BRZ, Toyota 86, and Scion FR-S models from 2013 to 2020. Designed for enthusiasts and professional engine builders alike, these forged pistons deliver exceptional strength, durability, and performance for naturally aspirated and mildly boosted applications.
With a precise 86.10mm bore size (+0.1mm over stock) and a 10:1 compression ratio featuring a dish design, these pistons help optimize combustion efficiency while maintaining reliability. Whether you’re building a high-performance street engine or a track-focused build, Manley’s Platinum Series pistons provide the durability and power potential you need.
Key Features:
Manley’s Platinum Series pistons incorporate advanced materials and manufacturing techniques to ensure superior performance and longevity:
- 2618 Alloy Forgings: Made from premium domestic 2618 alloy, these pistons offer outstanding strength and fatigue resistance under high-stress conditions.
- Chrome Moly Wrist Pins: Standard with premium chrome moly wrist pins for enhanced durability and reduced wear; select upgrades available for even greater strength.
- Exacting Ring Lands and Grooves: Precision-machined ring lands and grooves improve ring seal, reducing blow-by and increasing power output.
- Cam and Barrel Skirt Profiles: Optimized cam and barrel skirt designs reduce friction and wear on cylinder walls while supporting increased power.
- Unique Fixturing Process: Manley’s proprietary fixturing allows skirt turning and ring groove machining in a single operation, ensuring perfect ring groove-to-skirt squareness for consistent performance.
- 10:1 Compression Ratio with Dish Design: Balances power and reliability, ideal for performance builds requiring a slightly lower compression than stock.
- +0.1mm Bore Size (86.10mm): Provides a precise overbore for improved displacement and power potential without compromising engine longevity.
Construction & Design:
Each piston is forged from high-quality 2618 aluminum alloy, known for its excellent strength-to-weight ratio and thermal resistance. The pistons feature a dished crown design to achieve the 10:1 compression ratio, which helps accommodate various tuning and forced induction setups. The cam and barrel skirt profiles are carefully engineered to reduce friction and cylinder wall wear, enhancing engine efficiency and durability.
Manley’s unique manufacturing process includes a single-operation machining of the skirt and ring grooves, ensuring precise alignment and optimal ring sealing. The use of chrome moly wrist pins further strengthens the piston assembly, providing reliable wrist pin retention under high RPM and load conditions.
Installation & Fitment:
This piston set is a direct fit replacement for the FA20 engine in the Subaru BRZ (2013–2020), Toyota 86 (2017–2020), and Scion FR-S (2013–2016). Installation requires standard engine rebuild procedures and proper honing to the specified bore size. No special modifications beyond the specified bore increase are necessary.
