Overview:

The CP Pistons Piston and Ring Set is a precision-engineered upgrade designed specifically for the FA20 engine found in the Toyota 86 (2017–2020), Subaru BRZ (2013–2020), and Scion FR-S (2013–2016). Featuring an 86.5mm bore and a 12.5:1 compression ratio, this set of four pistons and rings offers enhanced durability and performance for enthusiasts seeking reliable power gains and improved engine response.

Ideal for performance builds, track use, or spirited street driving, these pistons help support increased cylinder pressures while maintaining OEM fitment and reliability. Whether you are rebuilding your engine or upgrading for higher boost or naturally aspirated performance, CP Pistons delivers quality components engineered to exacting standards.

Key Features:

This piston and ring set combines advanced materials and design to meet the demands of high-performance FA20 engines. Key features include:

• Set of four forged pistons designed for an 86.5mm bore size, matching factory specifications for a direct replacement or upgrade.
• High compression ratio of 12.5:1, optimized for improved combustion efficiency and power output.
• Precision-machined piston skirts and ring grooves for reduced friction and enhanced durability under high-stress conditions.
• Includes matching piston rings engineered to maintain optimal sealing and reduce blow-by.
• Manufactured by CP Pistons, a trusted name in high-performance engine components with a reputation for quality and reliability.
• Compatible with stock and modified FA20 engines, supporting a range of performance applications.

Construction & Design:

CP Pistons utilizes forged aluminum alloy for these pistons, providing an excellent balance of strength, lightweight characteristics, and thermal conductivity. The forging process ensures superior grain structure and resistance to fatigue compared to cast pistons, making them well-suited for high-performance and high-compression applications.

The pistons are CNC-machined to tight tolerances, ensuring precise fitment and consistent performance. The ring set is matched to the pistons to maintain proper sealing and minimize oil consumption, which is critical for maintaining engine efficiency and longevity.

Installation & Fitment:

This piston and ring set is designed as a direct fit replacement for the FA20 engine in the specified Toyota 86, Subaru BRZ, and Scion FR-S model years. Installation requires standard engine rebuild procedures and should be performed by a qualified technician to ensure proper clearances and ring end gaps.
