Wiseco Subaru FA20 Direct Injection Piston Kit 2.0L -16cc

Forged from 2618 aluminum, these Wiseco pistons are built for the demands of serious racing and performance engine builds. The 2618 alloy offers improved tensile strength, making these pistons a solid choice when you're pushing your Subaru FA20 engine hard. Each piston features precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is crucial for maintaining compression and preventing blow-by under high cylinder pressures.

Wiseco also applies an ArmorGlide skirt coating to these pistons. This coating helps reduce friction between the piston and cylinder wall, which can lead to quieter operation and improved durability by resisting seizure. The fully machined crown is designed to work with the -16cc dish volume, contributing to the engine's compression ratio. For forced pin oiling, these pistons are designed to ensure the wrist pin receives adequate lubrication, a vital detail for longevity in high-performance applications.

This set includes four pistons, each with an 87.00 mm bore and a 32.66 mm compression height, along with a 0.866 inch pin diameter. They are designed for sport compact applications and are intended for heavy to severe duty use. Please note that these pistons are not CARB approved and cannot be shipped to California.
