This listing is for a single Wiseco forged piston designed for the 95-98 Nissan 240SX with the KA24DE engine. It features a 90.50mm bore and a dished crown that results in a 9:1 compression ratio, making it suitable for performance builds where you need to manage compression. The piston is made from 2618 aluminum, a well-known material for its strength in high-performance applications.

Wiseco builds these pistons with features aimed at durability and improved performance. You'll find precision ring grooves, an anti-detonation groove, and other features designed to enhance ring seal. The piston also includes an ArmorGlide skirt coating, which helps reduce friction and resist seizure, contributing to quieter operation and better longevity under demanding conditions. The crown is fully machined, and the design incorporates forced pin oiling to ensure the wrist pin stays well-lubricated.

This piston is intended for heavy to severe duty performance applications. Please note that this part is not CARB approved and cannot be shipped to California.
