Wiseco Nissan RB25 87mm Bore 14cc Dome Piston Kit

Wiseco is well-known for making strong internal engine components, especially for high-performance applications. This Professional Series piston kit for the Nissan RB25DET engine is a prime example of their commitment to serious racers and builders. If you're rebuilding the top end of your RB25DET for demanding use, these pistons are built to handle it.

These pistons are forged and machined in the USA from 2618 aluminum, which gives them improved tensile strength for high-stress environments. They feature precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal. The fully machined crown and forced pin oiling are also notable details that contribute to their durability under heavy loads. Plus, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, making for a smoother, more reliable operation.

This kit includes six pistons, each with an 87.00 mm bore and a 14cc dome. They are designed for a 31.50 mm compression height and use a 0.827 inch pin diameter. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious engine builds, this Wiseco kit offers a well-built foundation.
