What material are these pistons made from?

These Wiseco pistons are forged from 2618 aluminum, which offers improved tensile strength. This material is chosen for its ability to withstand the high stresses and temperatures found in demanding performance applications.

What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide coating on the piston skirts is designed to reduce friction between the piston and cylinder wall. It also helps to resist seizure and contributes to quieter operation of the engine.

Are these pistons suitable for a street-driven car?

These pistons are part of Wiseco's Professional Series, designed for heavy to severe duty race builds. While they can be used in performance street applications, they are engineered for extreme conditions and may require other supporting modifications for optimal street use. They are also not CARB approved.

Product Details

If you're building a high-performance turbo setup for your 1990-2001 Acura Integra, this Wiseco forged piston kit is designed to handle the extreme demands of racing. These aren't your average pistons; they're crafted from 2618 aluminum, a material known for its impressive tensile strength, making them well-suited for the intense heat and pressure found in severe duty race applications. Wiseco machines these pistons right here in the USA, ensuring a high level of precision throughout the manufacturing process.

You'll find features like precision ring grooves, anti-detonation grooves, and other ring seal improvements that help maintain consistent compression and prevent detonation under boost. The piston crown is fully machined for a clean, consistent surface, and they incorporate forced pin oiling to keep the wrist pins properly lubricated. Plus, the ArmorGlide skirt coating helps reduce friction, resist seizure, and operate more quietly, which is a notable benefit when you're pushing your engine hard. This kit is intended for serious racers and builders who need components that can withstand heavy use.

This set includes four pistons, each with an 81.25mm bore and a -12cc dish volume, designed to work with the B18 engine. Please note that this kit is not CARB approved and cannot be shipped to California. It's always a good idea to consult your engine builder or the manufacturer's installation guide for specific details on assembly and compatibility with your turbo system components.
