If you’re looking to squeeze more out of your SR20DE, check out these Black Nitrided Exhaust Valves from Supertech. I’ve spent a fair amount of time tinkering with my Nissan builds, and I can tell you, these valves are a solid investment for anyone serious about performance. They’re not just some run-of-the-mill parts; they’re crafted to give your engine the edge it needs.
This set comes with 8 valves, each designed to fit perfectly into your Nissan 180SX, 200SX, 240SX, NX, or Sentra models from the early '90s up to the early 2000s. They’ve got a head diameter of 30.65mm (+0.5mm oversize), a stem diameter of 5.94mm, and a length of 102.40mm. The black nitrided finish isn’t just for looks; it enhances durability and helps reduce wear, which means you can expect these to last for years with proper care.
What I really appreciate is that these valves are engineered with precision. You’re not just dropping in a generic part; you’re installing something that’s been made to meet strict standards. That means less worry about performance drop-offs or premature failures. If you’re planning to push your engine, these valves will help you get the most out of it without breaking a sweat.
So, if you’ve got a Nissan in the lineup and you’re ready to upgrade, these exhaust valves are worth considering. They fit a range of models, including:
In short, these valves are a great way to enhance your engine’s performance. If you’re into modifying your ride and want something that’s built to last, you can’t go wrong with this set from Supertech.
