Overview

The Tomei Head Gasket is a metal gasket designed for Nissan RB20DE(T) engines with an 80.5mm bore and 1.8mm thickness. It is constructed from stainless material, chosen for its high heat capacity and ability to dissipate heat, which reduces the risk of head gasket failure. The thickness of the head gasket can be adjusted to increase engine compression ratio.
Show original supplier description
The Tomei Head Gasket is a performance-oriented component designed for Nissan RB20DE(T) engines. This metal gasket features a precise 80.5mm bore and a 1.8mm cross-section thickness. This gasket offers adjustability for engine tuning. By selecting a thicker head gasket, like this 1.8mm unit, you can increase your engine's compression ratio. Conversely, a thinner gasket can maintain the stock compression ratio. The durable and heat-resistant nature of the stainless material ensures superior sealing capabilities under high power demands. The Tomei Head Gasket is compatible with various Nissan Skyline models, including the 1986-1989 Skyline GTS/Turbo (R31), 1989-1992 Skyline GTS (R32), and 1999-2002 Skyline GT (R34). Tomei provides resources such as a Compression Ratio Calculator and Stock Engine Data to assist users in selecting the appropriate gasket thickness for their specific build goals.
