ND MX-5 Turbo Kit Brings Output to 248 HP

Package costs $5,695

The small and nimble Miata may not need extra power, but a new turbo kit from BBR has captured our attention. The Mazda tuning specialist has created a Stage 1 turbocharger package for the ND-generation MX-5, promising to squeeze 248 hp and 236 lb-ft of torque from the car's 2.0-liter engine.

BBR says the upgrade slashes the Miata's 0-60 time to just 5 seconds, with a top speed limited to 155 mph. In the past, we tested a standard 2016 Mazda Miata Club hitting 60 mph in 6 seconds flat.

The Mazda Miata turbo kit includes a new twin-scroll turbocharger that mounts onto a bespoke BBR cast-iron twin-scroll manifold. Other components include a carbon fiber turbocharger heat shield, a discretely placed high-flow K&N induction system, and a Starchip/EcuTek RaceRom ECU software package, which revises fuel, ignition, and boost calibration for better performance. Many components including the boost hoses and replacement battery tray are finished in black to look like factory-spec parts.

When BBR began experimenting with a new forced induction package for the Miata back in 2014, it initially considered supercharging and single scroll turbochargers. Ultimately, a twin-scroll turbocharger was deemed the most fitting way to increase power in the Miata, proving highly efficient and responsive while retaining a large boost upgrade margin for later power stages.

"Having rejected all other forced induction methods, our extensive dyno and road testing has proven that our choice of a low-back pressure twin-scroll turbocharger, with its enhanced exhaust scavenging ability, is the optimal solution," said BBR's Neil Mckay in a press release. "It works harmoniously with the original SKYACTIV-G layout and knock-resistant technologies, as is evident by the impressive power figures achieved at very modest boost pressures."

Available on newer Miatas, including the latest RF, the package is now on sale globally. In the U.S., it can be purchased from Flyin' Miata, BBR's exclusive distributor in the country. On Flyin' Miata's website, the price of the kit is listed at $5,695 and gains of "at least 70 hp and 70 lb-ft" are promised using a stock exhaust system. CARB approval, however, is still in progress.
