Wiseco Honda Turbo F-TOP 1.176 X 81.5MM Piston Shelf Stock Kit

If you're building a high-performance Honda B18 engine for serious racing, you need pistons that can handle the stress. This Wiseco Professional Series piston set is designed for those heavy to severe duty builds where reliability and strength are paramount. These aren't just off-the-shelf parts; they're crafted with the kind of attention to detail that serious racers demand.

Each piston starts as a forging from 2618 aluminum, chosen for its improved tensile strength, which is crucial when you're pushing an engine hard. Wiseco machines these pistons right here in the USA, paying close attention to precision ring grooves, adding anti-detonation features, and incorporating other ring seal improvements to ensure everything stays sealed under pressure. They also come with an ArmorGlide skirt coating that helps reduce friction and noise, while also resisting seizure. The fully machined crown and forced pin oiling are further details that show these pistons are built to last in demanding applications.

This set includes four pistons, each with an 81.50 mm bore and a 29.85 mm compression height, using a 0.8268-inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust B18 build that can take a beating, this Wiseco set is a solid choice.
