Product Fitment:

1989-1998 Nissan Skyline RB20E, RB20DE, and RB20DET 2.0L

The Cometic Gasket C4495-051 Multi-Layer Steel (MLS) Head Gasket is engineered specifically for the Nissan RB20E, RB20DE, and RB20DET 2.0L inline-six engines found in the iconic Nissan Skyline. Designed for performance builds and high-boost applications, this 80mm bore, .051-inch compressed thickness gasket delivers superior sealing integrity where factory gaskets simply can't keep up. Whether you're rebuilding a stock RB20DET or pushing elevated boost levels on a modified Skyline, this is the definitive head gasket solution for long-term reliability.

Key Features & Benefits

• Multi-Layer Steel (MLS) Construction — Three layers of embossed stainless steel provide unmatched sealing pressure and resistance to combustion blowout, far exceeding the durability of OEM composite gaskets
• Controlled Compression Thickness (.051") — Precision .051-inch compressed thickness maintains correct compression ratio geometry, making it ideal for stock bore rebuilds and mildly modified RB20 engines
• 80mm Bore Diameter — Matches the standard RB20 bore size exactly, ensuring proper coolant and oil passage alignment without modification
• Stainless Steel Stopper Layer — Embossed stopper rings around each combustion chamber create localized sealing load, preventing the micro-leakage that degrades conventional gaskets over time
• High-Temperature & High-Pressure Rated — Engineered to withstand the elevated cylinder pressures and thermal cycling demands of turbocharged RB20DET applications
• No Re-Torque Required — MLS design eliminates the need for re-torquing after initial heat cycles, simplifying the break-in process
• Viton® Rubber Coated Layers — Microscopic Viton coating on sealing surfaces conforms to minor surface imperfections for a leak-free seal, even on machined or lightly resurfaced heads
