Flyin’ Miata used to have a glaring omission in its turbo kit lineup. NA. NB. ND. Hmm. What about NC? Well, NC owners, you, too, now can enjoy a Flyin’ Miata turbo kit, including those in California, where it will be legal. The famed Miata tuning company will start offering the kit for sale on May 13 (with availability for California coming soon).

Flyin’ Miata began with a clean sheet to design a turbo system that meets the following criteria:
- Easy to install.
- Durable.
- Smooth power delivery.
- Still feels like a factory car.
- And meet emissions standards everywhere, including California.
After months of testing, which included “street and track, on cross-country drives, at elevation, at sea level and at multiple boost levels,” the kit is now ready for sale.
What kind of power does the kit’s GT2860RS turbo deliver? With 8 psi of boost, approximately 220 horses at the wheels on the stock 2.0 engine. At 11 psi, the power increases to around 240.
The kit comes with two sets of options.
First, two choices of turbine housings: the larger 0.86 A/R version, which taxes the cooling system less and provides more power potential, or the smaller 0.64 A/R, which “offers extremely quick response.”
Second, two downpipe options: a complete downpipe with a brand-new factory catalytic converter or a downpipe that comes with a fitting that you can weld to an existing catalytic converter.
The kit also includes formed, single-piece hoses and custom hard lines that reduce points of failure and quickly connect to stock components.
The manifold, turbine outlet, airbox and metal intercooler pipes receive a Cerakote treatment to combat high temperatures. The intercooler also has a thermal dispersion coating for better cooling and durability than bare aluminum. A turbo blanket protects brake lines and plastic valve covers from heat.
The only permanent change required for this kit? A single hole in the front bulkhead near the radiator. The good news? A template is included to easily make that hole.
A custom battery box retains the stock battery, and the washer bottle gets relocated. (Note: the kit only accommodates U.S.-sized washer bottles.)
To top it off, the Flyin’ Miata NC turbo kit comes with a Calibrated Success tune designed specifically for the kit and your Miata.
“The car drives like a factory car, with no bumps or weird hesitations,” Flyin’ Miata says in the description. “The tune and hardware are designed to be as durable, powerful and clean as possible. There is no back and forth to tune your car, you simply load the calibration in and you’re done.”
Pricing starts at $4999 for the complete kit.

Looks super solid. We'll probably be doing this, and "televising" it in the same way we did our NB Turbo install (albeit, not the complete FM kit, but most of it) here: https://www.youtube.com/watch?v=eDcGKZhr8Mw
The kit looks great, and I appreciate the amount of calibration time that went into it. That really makes the difference when you don't have to make excuses for how your "tuner" car drives. I'm usually a bit "meh" on turbo blankets though, as they provide a great place for leaking oil to pool up and potentially create a thermal event on-track.
How crazy is it that the NC is now like 20 years old?
In reply to David S. Wallens :
Sometimes I think it's kind of crazy that, for as long as the Miata has been made, we only have four different versions.
(And it'll be interesting to see what the fifth version ends up looking like.)
In reply to goingnowherefast :
The turbo heat shielding was the last component to get signed off. We looked at a number of different solutions including coatings, heat shields and blankets. Packaging is extremely tight there with a bunch of brake lines and the ABS unit close to the turbo. The blanket was the only solution that gave sufficient protection and was reproducible. It's a custom one for this application, not a generic.
I'll take a look at it today, I have a suspicion that any leaking from the center housing will not be able to pool.
We're doing a live Q&A on the kit today at 2:00 Mountain.

Congrats on the product launch Keith (and all the rest of the FM crew of course)!

Time certainly marches on. The ND is almost 10 now.

2025 is the ND's 10th model year. In 2026 it will be the longest running Miata generation, passing the NC's 10 model years...

In reply to Rodan :
Crazy, huh? My parents have an early ND. Still looks new.
