Show original supplier description
The Tomei TA4070-NS06B is a high-performance metal head gasket engineered for Nissan RB25DE and RB25DET engines, including NEO6 variants. This gasket measures 87.0mm in bore and 1.5mm in thickness, offering a specific option for engine builders looking to tune their compression ratio. Constructed from stainless steel, this head gasket boasts superior heat dissipation properties. This characteristic significantly minimizes the risk of head gasket failure, even under demanding conditions, by efficiently managing thermal loads. The material choice ensures durability and reliability for performance applications. This specific head gasket is designed to fit NISSAN 32 SKYLINE, NISSAN 33 SKYLINE, and NISSAN 34 SKYLINE models equipped with RB25DE, RB25DET, RB25DE NEO6, and RB25DET NEO6 engines. It is a direct replacement for the stock gasket, allowing for precise installation and optimal sealing. While the gasket itself allows for cylinder capacity adjustment through its thickness, Tomei also offers other thicknesses (1.2mm and 1.8mm) to cater to different build requirements. This 1.5mm version provides a balance for maintaining or slightly modifying compression ratios.
