National Speed Guarantee
Our Guarantee
12-Month / 12,000-Mile Workmanship Warranty
At National Speed, every installation and performance package is completed with precision and attention to detail. We stand behind our work because the vehicles we build carry our reputation.
This warranty covers issues directly related to installation performed by our team. If a workmanship-related problem occurs, we will diagnose and correct it.
Built With Care
We treat every vehicle with the same care we expect for our own. While your vehicle is in our facility, it is stored in our secured building, handled by trained technicians, and protected during service and testing.
Before any work begins, we review:
- Calibration requirements
- Expected performance outcomes
- Components being installed
- Supporting modifications required
Jordan, Vlad and Kevin are the best! I was looking for a place who could handle a custom engine tune in my '95 NSX Twin Turbo J Swap with Haltech ECU. I'm so glad I chose them!

What Our Warranty Covers
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since 1966, when designers at Letraset and James Mosley, the librarian at St Bride Printing Library, took a 1914 Cicero translation and scrambled it to make dummy text for Letraset’s Body Type sheets. It has survived not only many decades, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised thanks to these sheets and more recently with desktop publishing software including versions of Lorem Ipsum.
