Overview

The Tomei Cylinder Head Gasket is a multi-layer metal gasket designed for Nissan RB25DET and RB25DE engines, including NEO variants. It features an 87.0 mm bore and a 1.8 mm thickness, offering a thicker option for builders needing to lower static compression ratio for high-boost applications or specific piston/deck height combinations.

This gasket is engineered with reinforced sealing around the combustion chambers and carefully designed water and oil passages, providing stronger resistance to blowouts and consistent sealing under demanding conditions. It is a direct fit for RB25-powered Skyline and Stagea models, serving as a durable alternative to factory head gaskets for high-performance builds.
Show original supplier description
The Tomei Cylinder Head Gasket (part number TA4070-NS06C) is a premium multi-layer metal gasket engineered for Nissan's RB25 engine family, including RB25DET, RB25DE, and NEO variants. With a bore size of 87.0 mm and a thickness of 1.8 mm, this gasket is specifically designed to manage higher cylinder pressures and temperatures encountered in high-boost or high-compression scenarios. This thicker gasket is an ideal choice for engine builders who need to lower the static compression ratio, a common requirement when increasing boost levels or when accommodating specific piston designs and deck heights. Tomei's design incorporates reinforced sealing around the combustion chambers and precisely engineered water and oil passages for consistent and reliable sealing under extreme operational stress. Directly fitting RB25-powered Nissan Skyline (R32, R33, R34 generations) and Stagea (WGNC34) models, this Tomei head gasket is a performance-oriented component. It is well-suited for turbocharged applications aiming for higher power outputs, offering greater flexibility in compression ratio management. Its robust construction and precision engineering make it a trusted choice for both engine refreshes and aggressive forced-induction setups, embodying Tomei's commitment to Japanese performance engineering.
