Supertech Performance NEVI-1006 Inconel Exhaust Valve for Nissan SR20

The Supertech Performance NEVI-1006 is a high-performance Inconel exhaust valve engineered for Nissan SR20 engines. This premium valve is designed for engines operating under extreme conditions, including turbocharged and supercharged applications where exhaust temperatures reach critical levels.

Key Features:

• One-piece forged construction from Inconel nickel-base alloy for superior high-temperature strength
• Precision CNC machined to exacting tolerances for optimal performance
• Special heat treatment process optimizes hardness for demanding applications
• Swirl polished surface finish reduces friction and wear
• Hardened valve tip and seat for extended durability
• Undercut stem design improves flow characteristics
• Single groove keeper design for reliable valve retention

Why Inconel Material:

Inconel (nickel-base alloy) exhaust valves are specifically engineered for engines that experience extreme exhaust temperatures. This material choice is essential for high-boost turbocharged and supercharged applications where traditional stainless steel valves would fail. The Inconel construction maintains superior strength and resists deformation even under sustained high-temperature operation, making it the preferred choice for serious performance and racing applications.

Manufacturing Excellence:

Each Supertech valve undergoes rigorous quality control including ultrasonic testing, X-ray inspection, and laser measurement verification. The manufacturing process includes stress-relief heat treatment followed by their proprietary Superfinishing process to ensure each valve is free from imperfections and meets precise dimensional specifications.

Supertech Performance draws on over 30 years of valve manufacturing experience, working closely with professional engine builders to continuously refine and improve their products. This valve represents the ultimate choice for builders seeking maximum reliability and performance in high-output Nissan SR20 engine builds.

Note: Valve keepers (locks) sold separately. Professional installation recommended.
