Product Details

The Supertech Performance NEVI-1032/7-L is a high-performance Inconel exhaust valve engineered specifically for Nissan RB26DETT engines. This single valve features a +1mm oversize head diameter (31.15mm) and an extended valve tip that is 1.5mm longer than standard, making it ideal for modified cylinder heads and high-performance applications.

Key Features:

  • Constructed from premium Inconel 751 superalloy for superior heat resistance and durability
  • Sodium-filled design significantly reduces valve head temperatures in turbocharged applications
  • +1mm oversize head diameter (31.15mm) for improved airflow in ported heads
  • Extended valve tip (1.5mm longer at 102.7mm total length) accommodates modified valvetrain geometry
  • Stem diameter: 6.94mm for precise fitment
  • Average 10% weight reduction compared to OEM valves
  • Enhanced material strength allows for more aggressive spark timing advances

Inconel valves are essential for high-boost turbo engines where exhaust gas temperatures exceed the capabilities of standard stainless steel valves. The sodium-filled construction provides exceptional thermal management, improving valve longevity and maintaining optimal sealing under extreme conditions. This valve requires valve guide RET-NRB60-TS-2 for proper installation. Sold individually.

Second time customer.... very pleased with selection, prices, and ease of shopping....

Easy, easy, easy

Found the part I needed and the process was very fast.

checkout was fast and easy and shipping was cheap

Had trouble ordering to Puerto Rico. Ended up shipping it to my brother. Tried to get help on the phone twice and the person was not very helpful and sounded annoyed by me. Problem 1: When using credit card it had an error about fraud with both Amex and Visa. Problem 2, I tried Paypal, had and estimated shipping cost, went through the Paypal site and when it got back to your site it said it couldn't estimate the shipping cost so I couldn't finish the transaction, even though it had estimated it 3 screens before. I would have preferred for you to just ship it directly to me but that was impossible.
