Product Description

The Wiseco **K727M86** piston set is a high-performance upgrade specifically designed for the 2.0 L FA20 engine found in the Subaru BRZ and Toyota 86 / Scion FR-S (2013-2021). With a forged 2618 aluminum construction, these pistons are built for strength, durability, and reliable operation under aggressive driving conditions.

Featuring an 86 mm bore and a -9.5 cc dish design, these pistons produce a moderate compression ratio (~10.5:1), which is well-suited to naturally aspirated or lightly tuned turbocharged FA20 builds. The ArmorGlide® coated skirts reduce friction and improve longevity, while the strutted forging adds robustness where it matters most.

Each kit comes with four pistons, wrist pins, circlips, and a high-performance ring set - everything needed for a full rotating assembly build. Ideal for engine builders and tuners aiming for a balance of performance, reliability, and precision in a sport compact platform.
