Wiseco Honda S2000 F20C 89.0mm Bore 11:1 CR Custom Pistons

If you're rebuilding the engine in your 2000-2009 Honda S2000 for serious performance, these Wiseco pistons are a solid choice. They're designed for builders who are pushing their F20C engine hard, whether that's on the track or in a demanding street application. These pistons are forged from 2618 aluminum, which gives them improved tensile strength over cast aluminum, making them well-suited for the higher stresses of performance builds.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. This attention to detail helps ensure consistent performance and durability under heavy load. They also come with an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure. The crown of the piston is fully machined, and they feature forced pin oiling for better lubrication of the wrist pin.

This set is designed for a 89.0mm bore and has an 11:1 compression ratio, which is a popular choice for naturally aspirated builds looking for a good balance of power and pump gas compatibility. Keep in mind these pistons are not CARB approved and cannot be shipped to California. You'll need to refer to the manufacturer's installation instructions for specific details on installation, including required clearances and torque specifications.
