Supertech Dual Valve Spring Kit Acura NSX 1990-2005 for 1991-2005 Acura NSX SPRK-H1005D-NSX | Vivid Racing
If you're diving into a valvetrain overhaul, you really can't overlook the Supertech Spring and Retainer kits. These aren't just any old parts; they’re precision-matched sets designed specifically for folks who crave performance. Trust me, after putting these through their paces, I can confidently say they deliver on quality and value without cutting corners.
What’s in the box? Well, you get a complete set of 16 springs, 16 retainers, and 16 seat locators. That’s right—everything you need to get your engine breathing better and performing at its peak.
Now, let’s talk specs. The seat pressure is set at a solid 80 at 36.4, and when it’s time to really push those valves, you’re looking at an open pressure of 234 at just 12. That means these springs can handle some serious lift, with a max of 15.7mm before coil bind kicks in at 20.70mm. The rate sits at a nice 11.5, which gives you just the right amount of responsiveness without feeling too stiff.
For the Acura NSX owners out there, these springs are a perfect fit for models from 1990 to 2005. Whether you’re hitting the track or just want a little more kick on the street, this kit is built to handle it. The part numbers you’ll want to remember are SPR-H1005D for the springs, RET-K20A2/T2-NS for the retainers, and SEAT-H1020DS for the locators. It’s all about making sure you have the right pieces in place to keep your engine running smoothly.
So, if you’re in the market for a reliable upgrade, these Supertech kits are definitely worth considering. They’ve got the performance edge, and you’ll feel the difference when you hit the gas.
