87mm Bore x 1.5mm Head Gasket:

The metal head gasket features an 87mm bore size, which is suitable for stock RB26DETT engines (86mm bore) and mildly overbored engines up to 87mm. The 1.5mm thickness is ideal for maintaining proper compression ratio on stock or mildly modified engines. The metal construction provides superior sealing and durability compared to composite gaskets, especially in high-boost applications.

Why Metal Gaskets?

Metal gaskets offer several advantages over traditional composite gaskets for high-performance applications:

• Better Sealing: Metal gaskets conform better to imperfect surfaces
• High-Boost Capable: Handle increased cylinder pressure without failure
• Durability: Won't degrade or blow out like composite gaskets
• Reusability: Can be reused if in good condition (inspect carefully)
• Heat Resistance: Better withstand extreme temperatures

Complete Gasket Kit:

This combination set includes all the critical gaskets needed for an RB26DETT engine build or rebuild. Having all gaskets from one manufacturer ensures consistent quality and proper fitment. The kit saves time and money compared to sourcing gaskets individually.

Metal Intake & Exhaust Manifold Gaskets:

The metal intake and exhaust manifold gaskets provide superior sealing compared to composite gaskets. The metal construction withstands the extreme heat of the exhaust manifold and the vacuum of the intake manifold without degrading or failing. This is especially important on modified engines running increased boost.

Metal Throttle Body Gaskets:

The kit includes both inner and outer metal throttle body gaskets (3 of each for the 6-cylinder RB26). These metal gaskets ensure proper sealing between the throttle bodies and intake manifold, preventing vacuum leaks that can cause poor idle and drivability issues.

Oil Galley Orifice:

The included oil galley orifice is a critical component for proper oil flow in the RB26DETT. This small but important part ensures correct oil pressure distribution throughout the engine.

Why Tomei?

Tomei Powered has been engineering high-performance RB26DETT components for over 50 years, with deep roots in Japanese motorsport. Their gaskets are proven on race tracks and dyno sheets worldwide, delivering consistent, reliable sealing. Every Tomei product is manufactured in Japan to the highest quality standards.

87mm Bore Sizing:

The 87mm bore is suitable for:

• Stock RB26DETT: 86mm bore (provides 0.5mm clearance per side)
• Overbored Engines: Up to 87mm bore
• Note: For larger bore sizes, different gaskets are required

1.5mm Thickness:

The 1.5mm head gasket thickness is ideal for:

• Stock compression ratio builds
• Mildly modified engines
• Engines using stock pistons
• Note: Thicker gaskets available for lowering compression ratio

Installation Tips:

• Clean all mating surfaces with brake cleaner and scotch-brite pad
• Inspect block and head surfaces for warping (machine if necessary)
• Use ARP head studs or new OEM head bolts
• Follow proper torque sequence and specifications
• Do not use sealant on metal head gasket
• Torque head bolts in multiple stages
• Allow engine to cool completely before retorquing (if required)

Perfect For:

• RB26DETT engine rebuilds and refreshes
• High-performance builds running increased boost
• Engine swaps requiring complete gasket kit
• Track cars and race applications
• Anyone wanting Tomei quality and reliability

Perfect For: RB26DETT builders seeking a complete, high-quality gasket kit with proven Tomei engineering for reliable sealing in high-performance applications.

Pro Tip: Always inspect head and block surfaces for warping before installation - even minor warping can cause head gasket failure.
