Cometic Nissan SR20DE / DET Cylinder Head Gasket. .051 in Thick, 86.5 mm Bore Size

When you're rebuilding the top end of your Nissan SR20DE or SR20DET engine, a solid cylinder head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the demands of these engines, offering a reliable seal for your Sentra, 200SX, or NX.

This particular gasket measures .051 inches thick and has a bore size of 86.5 mm, designed to fit specific SR20 applications including those with VCT. The MLS construction uses multiple layers of steel to provide a strong, durable seal that can better accommodate engine block movement and temperature changes compared to older gasket types. The outer layers are coated with Viton, a synthetic rubber material known for its resistance to heat and oil, further enhancing the gasket's sealing capabilities and longevity.

This gasket is a direct fit for your 1991-1994 and 1998-2001 Nissan Sentra, as well as the 1995-1998 200SX and 1991-1993 NX. Ensure your engine block and cylinder head surfaces are clean and properly prepared before installation, as this is key to achieving a leak-free seal.
