Boasts 0-60 mph in 4.9 seconds and 150 mph top speed.
UK-based Brodie Brittain Racing (BBR) has been turbocharging Miatas for over twenty years and its latest project is the most powerful upgrade the littler roadster has ever seen. Dubbed the Mazda MX-5 GT270, the upgrade sees output increased to 268 hp and 227 lb-ft of torque courtesy of Garrett GT25 turbochargers, new exhaust manifold and intercooler and some upgraded electronics. The result is a 0-60 mph time of 4.9 seconds and a top speed of 150 mph.
By contrast, the 2.0-liter Sport Tech Roadster Coupe on which it's based manages 0-62 mph in 7.9 seconds and tops out at 136 mph. In addition to having 108 more horses and 88 lb-ft more torque, the GT270 comes with a range of optional chassis upgrades, substantially improving dynamics, as well as launch control, throttle shift and auto throttle blip on down changes. An uprated Exedy clutch comes with a higher clamping pressure to handle all that extra twisting power. "BBR Turbo" badging and branded exhaust tailpipe trim sets this apart from the standard roadster. Only 100 units are earmarked for production, priced at £29,995 on the road.
