Product Description

The Wiseco K549M88AP is a professional-series forged piston kit specifically engineered for the Nissan VG30DETT 3.0 L twin-turbo V6 found in 1990-1996 300ZX models. Built from 2618 aerospace-grade aluminum, these pistons are designed for high-performance, forced-induction, and race-level builds.

With a -9.0 cc dished crown, these pistons achieve a lower compression ratio (~8.5-8.9:1), making them well-suited for boosted applications. The full-round strutted forging adds structural strength, and the ArmorGlide® skirt coating reduces friction and improves durability. Forced pin oiling ensures excellent lubrication of the 22 mm wrist pins under high load.

This complete kit includes six pistons, wrist pins, circlips, and a premium 8800XX ring set, giving you everything needed for a robust performance build. Ideal for race engines or high-stress turbo setups, the K549M88AP delivers reliability, strength, and precision for serious engine builders.
