Brodie Brittain Racing — or simply BBR — unveiled today the MX-5 GT270, which is based on the 2013 MX-5 Sport Tech Roadster Coupe .
With the GT270, BBR focused most of its attention on upgrading the engine. For this, the tuner added a turbocharger, an upgraded exhaust manifold, an intercooler, and an ECU calibration. As a result the engine now delivers a mighty 268 horsepower at 7,350 rpm — a 110-horsepower bump over the standard 2.0-liter Sport Tech model. Torque also jumped to 200 pound-feet available — an 88 pound-feet boost — from 3,000 rpm to 7,000 rpm. As a result of the added power, the MX-5 now sprints from 0 to 60 mph in just 4.9 seconds and hits a top speed of 150 mph.
The ECU tune also includes three driving modes. In Mode One offers up fast response from the throttle in road driving; Mode Two adds a launch-control system set at 3,800 rpm, automatic throttle lip and full-throttle gearshifts; Mode Three is an economy mode; and Mode Four is a valet mode that limits the engine speed to 3,500 rpm, so valets can’t go all Ferris Bueller’s Day Off on your MX-5.
This 268 horsepower makes the GT270 is the most powerful MX-5 built to date by this well-known tuner. With this comes the need for an updated driveline, so BBR added in an Exedy clutch for extra bite.
In order to handle the extra power, buyers can also equip the MX-5 GT270 with an optional performance suspension upgrade offered by Koni. This new suspension system includes adjustable dampers and new lowering springs that will bring the tiny roadster closer to the ground and increase its ability to handle the twisty stuff.
Also available for an extra fee is an optional performance brake system that features EBC Yellow Stuff pads, stainless-steel brake lines and Castrol SRF brake fluid.
A third optional upgrade is a 2.5-inch-diameter stainless-steel exhaust system with sports catalyst. This exhaust system allows the engine to exhale more effectively, which bumps its out put to 302 horsepower and 254 pound-feet of torque. That’s enough to get the Miata to 60 mph in 4.7 seconds and up to 165 mph by our estimations.
The BBR MX-5 GT270 is limited to only 100 units, and will be priced from £29,995 - or about $48,500 at the current exchange rates.
