Wiseco Nissan QR25DE 90.00 mm Bore 32.00 mm CH -19.50 CC Piston Set

This piston set from Wiseco includes four forged pistons, designed specifically for Nissan QR25DE engines. Each piston measures a 90.00 mm bore with a 32.00 mm compression height and a -19.50 CC dish volume. These are built for demanding performance applications, often found in sport compact builds where durability and strength are critical.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for heavy to severe duty race builds. They feature precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The piston crown is fully machined for accuracy, and they incorporate forced pin oiling to ensure proper lubrication. Additionally, an ArmorGlide skirt coating is applied to reduce friction, resist seizure, and contribute to quieter operation.

These pistons are manufactured in the USA. Please note that this set is not CARB approved and cannot be shipped to California. For installation, refer to the manufacturer's instructions for specific details regarding pin diameter and assembly.
