Mazworx/Apexi SR20DET Head Gasket

The Mazworx/Apexi SR20DET Head Gasket is engineered specifically for Nissan SR20 engines, compatible with both DE and DET variants in front-wheel drive (FWD) or rear-wheel drive (RWD) configurations. It is also recommended for pairing DE/DET engine blocks with VE/VET heads, ensuring versatile application across popular SR20 setups.

Key Features

• Full Grommet Design: Provides superior sealing between the cylinder head and engine block, enhancing durability and reliability under demanding conditions.
• Advanced Material Bonding: Incorporates a molybdenum bonding layer that reduces scrubbing and wear during heat expansion cycles, maintaining gasket integrity over time.
• Pre-production Coating: Features an NBR nitrile coating for improved oil and water sealing on rough surfaces, promoting leak-free performance even in challenging environments.
• High Boost Capability: Validated through testing with over 40 psi of boost and achieving over 1000 wheel horsepower (whp) without failures, making it suitable for high-performance builds.
• Custom Dowel Options: Comes standard with 14mm dowels designed for 11mm head studs; optional dowel machining is available for 1/2″ head studs (16mm dowels) or GTi-R (15mm dowels) configurations, providing tailored fitment options.
• Bore Size: Gasket bore size options include 88mm and 91mm with various thicknesses (1.2mm, 1.5mm, and 2.0mm) to accommodate different engine modifications; cylinder bore size should be at least 1mm smaller than the gasket bore for optimal sealing.
• Custom Machining: Dowel pins are machined to order, typically requiring 1-2 days for production to ensure precise fitment for your application.

For enhanced sealing performance, pairing this gasket with Mazworx’s custom step decking service on the engine block is recommended. This combination results in a robust seal capable of handling extreme boost levels and high horsepower applications.
