87.5mm Bore Diameter:

The 87.5mm bore diameter is designed for stock bore 2JZ-GTE engines (86mm) and mild overbore applications. This gasket provides proper sealing for stock displacement builds and slightly enlarged bores. If you're building a stroker or significantly overbored engine, verify the bore diameter matches your build specifications.

1.2mm Thickness:

The 1.2mm thickness is engineered to provide optimal compression ratio for high-performance turbo builds. Thicker head gaskets lower compression ratio, which is beneficial for high-boost applications as it reduces the risk of detonation. The 1.2mm thickness is a popular choice for 2JZ-GTE builds running moderate to high boost levels.

Multi-Layer Steel (MLS) Construction:

Tomei's MLS head gasket features multiple layers of stainless steel with specialized coatings. This construction provides superior sealing under extreme cylinder pressures and temperatures. The multiple layers allow the gasket to conform to minor surface imperfections while maintaining a reliable seal. MLS gaskets are the gold standard for high-performance turbo builds.

High-Boost Turbo Applications:

This Tomei head gasket is specifically engineered for high-boost turbo applications where cylinder pressures far exceed stock levels. The MLS construction and premium materials ensure reliable sealing even under extreme conditions. This gasket is a critical component for any serious 2JZ-GTE performance build.

Why Tomei?

Tomei has been manufacturing premium performance parts for Japanese engines for decades. Their head gaskets are engineered using extensive dyno testing and real-world racing experience. Every Tomei gasket is manufactured in Japan to the highest quality standards and tested to ensure it can withstand the demands of high-performance builds.

Installation Tips:

• Machine cylinder head and block surfaces to proper RA finish
• Clean all surfaces thoroughly - no oil or debris
• Install gasket dry - do not use sealant on MLS gaskets
• Follow Tomei's torque specifications and sequence exactly
• Use ARP head studs or quality OEM head bolts
• Torque in multiple steps to final specification
• Allow engine to heat cycle before retorque (if required)
• Check for leaks after initial startup

Perfect For:

• High-boost 2JZ-GTE turbo builds
• Engine rebuilds requiring premium head gasket
• Stock bore and mild overbore applications
• Supra and Aristo performance builds
• Anyone building a reliable high-horsepower 2JZ-GTE

Perfect For: Toyota 2JZ-GTE owners building high-boost turbo engines with the Tomei head gasket featuring 87.5mm bore, 1.2mm thickness, and MLS construction.

Pro Tip: The 1.2mm thickness lowers compression ratio for safer high-boost operation - verify this matches your build requirements.

Made in Japan: Premium Tomei quality with multi-layer steel construction engineered for extreme performance.
