Flyin' Miata is known for their well-engineered, complete, emissions legal, high quality turbo systems for NA, NB and ND Miatas. And now this same level of excellence is available for the NC chassis!

We started from the ground up to design a turbo system that would meet our standards. It had to be emissions legal everywhere - including California. It had to be durable. It had to be easy to install. It had to have smooth power delivery and feel like a factory car. We tested multiple cars for months on the street and track, on cross-country drives, at elevation, at sea level and at multiple boost levels. And now it's here.

8 psi of boost out of a GT2860RS turbo means roughly 220 hp at the wheels on the stock 2.0 engine. 11 psi will produce approximately 240 hp at the wheels.

We offer the system with a choice of turbine housings: the larger 0.86 A/R will put less stress on the cooling system on track while the smaller 0.64 A/R offers extremely quick response.

The engine calibration was done by Calibrated Success, an OE-level calibrator that is on a different level from what has been seen in the Miata world before. The car drives like a factory car, with no bumps or weird hesitations. Careful attention was paid to catalytic converter health - this goes far beyond simply trying to reach a certain air/fuel ratio. The tune and hardware is 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. The MAF assembly and cold-side tubing was designed for ideal driveability - airflow through the MAF was designed for a smooth laminar flow for best results. Boost is set by the wastegate with no need for a secondary boost controller.

The cast turbine outlet has a constantly increasing cross-sectional area to ensure good flow and provides good clearance to other hard points for both durability and ease of installation. It terminates in a 4" V-band where it mates to the rest of the downpipe.

The stock catalytic converter is retained. We can either provide a complete downpipe with a brand new factory cat inside or you can weld the included fitting to your existing catalytic converter. Both options are emissions legal. We do not offer a cat delete option.

To make it easy to install, we designed single-piece formed hoses and custom hard lines to quickly connect to the stock components. This means fewer points of failure and perfect fitment. We paid careful attention to the cooling system design and water flow, making it as efficient as possible and taking lessons from the OEs as well as our own experience with other Miatas. We also tested the system extensively on track and the street, including 45 minute uninterrupted sessions at High Plains Raceway.

The manifold, turbine outlet, airbox and metal intercooler pipes are Cerakoted to handle high heat and retain their good looks over time. The intercooler has a thermal dispersion coating to give maximum cooling with better durability than bare aluminum. There is a custom turbo blanket for the turbo to protect brake lines and the plastic valve cover from heat. There are small details everywhere, such as a finishing cover for the sound tube hole.

The stock battery is retained inside a custom battery box. The air intake is a true cold air design, with intake temperatures at ambient. The only permanent modification to the car is a single hole in the front bulkhead near the radiator. We provide a template to make this easy - which doubles as an escutcheon for a clean finish.

Notes:

We recommend an 8 psi boost limit on 2006-08 cars as well as automatic cars due to their cast engine internals. Yes, the kit works on automatics.
The redline is the same as stock. The dyno charts show a 7000 rpm NC1 redline as that car was running NC1 engine management.
The washer bottle is relocated. This new location will only fit with the standard US washer bottle (Mazda part NE51-67-481A, available from Flyin' Miata). The larger bottle (NE52-67-481A) used in some other countries will not fit.
The boost level is set with wastegate preload. This is what we recommend for cars operating at or near sea level. Cars at altitude can use a manual boost controller to get slightly quicker boost rise and the ability to adjust boost more easily.
We have confirmed that it will NOT fit with RHD cars.
CARB EO #D-601-6

2.5 information: we have not tested this yet although we believe it should fit if you use drop mounts. We cannot provide a tune for a 2.5 application at this time but may be able to do so in the future.

Install and technical videos are available on our YouTube channel.

Note that this product may take a few days to ship as it's fairly complex to assemble and pack.
