Cometic RB26DETT Exhaust Gasket – Nissan Skyline GT-R R32 R33 R34
Maintain reliable exhaust manifold sealing with the Cometic RB26DETT Exhaust Gasket C4202-030, a high-quality multi-layer steel exhaust manifold gasket set designed for Nissan’s legendary 2.6L RB26DETT twin-turbocharged engine.
Developed for compatible Nissan Skyline GT-R R32, R33 and R34 applications, this Cometic MLS gasket features a 0.030-inch compressed thickness and a precision-engineered oval exhaust port design.
Whether restoring a classic Nissan Skyline GT-R, rebuilding an RB26DETT engine or servicing a performance exhaust manifold, a correctly specified gasket is essential for maintaining a reliable seal.
Why Choose a Cometic RB26DETT Exhaust Gasket?
The exhaust manifold gasket creates a seal between the engine’s cylinder head and exhaust manifold.
This sealing area experiences significant thermal cycling as the engine heats up and cools down during operation.
Deteriorated exhaust gaskets can contribute to exhaust leaks, unwanted noise and reduced sealing reliability.
Cometic’s MLS gasket technology uses layered steel construction to provide a durable sealing solution for compatible engine applications.
The C4202-030 is designed specifically for the Nissan RB26DETT engine family.
Multi-Layer Steel Construction
Multi-layer steel, commonly known as MLS, is widely used in modern performance engine gasket applications.
Its construction allows the gasket to accommodate the thermal and mechanical demands of the engine when installed between properly prepared mating surfaces.
The Cometic C4202-030 features a compressed thickness of 0.030 inches, equivalent to approximately 0.76 mm.
This specification makes it important to confirm the gasket’s compatibility with the cylinder head, exhaust manifold and intended engine build.
Nissan Skyline GT-R R32 Compatibility
The Nissan Skyline GT-R R32 introduced the RB26DETT engine, becoming one of the most recognisable Japanese performance vehicles.
For owners carrying out restoration, exhaust system maintenance or performance engine work, the Cometic MLS exhaust manifold gasket provides an application-specific sealing component.
Fitment should be checked against the existing manifold configuration.
Nissan Skyline GT-R R33 Compatibility
The R33 Skyline GT-R continued using the turbocharged RB26DETT engine.
The Cometic C4202-030 gasket set is suitable for compatible RB26DETT exhaust manifold arrangements and is an option when replacing worn or damaged manifold gaskets.
Nissan Skyline GT-R R34 Compatibility
The Nissan Skyline GT-R R34 also features the RB26DETT engine.
During exhaust manifold servicing or engine rebuilding, maintaining correctly sealed exhaust connections is essential.
The Cometic MLS exhaust manifold gasket set is designed for compatible RB26DETT applications.
Designed for Demanding Exhaust Conditions
Turbocharged engines generate substantial exhaust heat, making gasket condition and installation quality particularly important.
Cometic manufactures performance engine gaskets for applications where material quality, dimensional consistency and dependable sealing are essential.
The C4202-030 provides a multi-layer steel sealing solution for the RB26DETT exhaust manifold interface.
For correct installation, inspect the mating surfaces, confirm gasket alignment and use the applicable manufacturer’s torque procedure.
