Wiseco Nissan Turbo Domed +14cc 1.181 X 86.5 Piston Kit

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in Nissan RB26DETT engines. The material choice here is important; 2618 aluminum offers improved tensile strength, which is crucial for handling the high pressures and temperatures found in boosted, high-performance applications. This particular kit is designed with a domed crown, featuring a +14cc volume and a bore size of 86.50 mm, intended to work with specific compression height and pin diameter requirements for optimal engine tuning.

Wiseco has packed these pistons with features aimed at durability and performance. You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which helps maintain compression and prevent blow-by. The ArmorGlide skirt coating is a notable addition, designed to reduce friction, resist seizure, and contribute to quieter operation. These pistons are fully machined, including the crown, and feature forced pin oiling to ensure the wrist pin stays well-lubricated under demanding conditions.

This set of six pistons is intended for heavy to severe duty race builds where reliability and strength are paramount. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming to push their RB26DETT engines to the limit, these Wiseco pistons offer a well-built foundation.
