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.

Brodie Brittain Racing (BBR) Ltd, creator of the original turbocharged Mazda MX-5 in 1990, is proud to announce the launch of its most potent package yet - the Mazda MX-5 GT270.
Built from a brand new 2013 model year specification MK3.5 (NC) 2.0-litre Sport Tech Roadster Coupe, the BBR GT270 leverages three decades worth of BBR MX-5 expertise with a breathtaking turbocharged engine producing 268bhp (270PS.) Combined with advanced electronic upgrades and optional chassis enhancements, the all-round improvement of the Mazda coupe’s dynamics is dramatic, delivering the last word in MX-5 driving excitement for the true performance enthusiast. With a strictly limited production run of 100 numbered cars, BBR has created the ultimate, exclusive MX-5 designed to appeal to both enthusiast and collector alike.
The BBR GT270 turbo – Performance, driveability and refinement
The BBR development team’s primary goals for the Mazda MX-5 GT270 turbo project were to deliver stunning performance in combination with superior driveability, whilst retaining a factory feel and under bonnet appearance.
Central to the BBR GT270 driving experience is the 2.0-litre engine, which has been subject to extensive development by BBR’s technicians to perfect the ideal turbocharger, exhaust manifold and intercooler combination deliver the optimal blend of performance, driveability and reliability.
The BBR GT270 is the most powerful new Mazda MX-5 on sale today, producing 268bhp at 7350rpm, some 110bhp more than the standard 2.0-litre Sport Tech model. More impressively, the car’s peak torque figure of 227lb.ft (88lb.ft more than the standard MX-5 2.0-litre Sport) arrives at 5100rpm, with over 200lb.ft available from 3000 rpm to 7000rpm, emphasising the superior driveability of the BBR car. Given the considerable torque increase over standard BBR has installed an uprated Exedy clutch with a higher clamping pressure than the factory unit to ensure longevity of the GT270’s powertrain.
Commenting on the launch BBR Director Neil Mckay said “Our objective with the GT270 was to give a factory style progressive power delivery, with peak power at the top of the engine’s rev range. With careful component selection allied to extensive ECU recalibration, BBR has achieved exceptional power gains at very low turbo boost pressures, thus ensuring maximum efficiency and longevity for GT270 owners.”
Compared to alternative normally aspirated tuned MX-5s, the GT270’s quick spooling Garrett GT25 ball bearing turbo provides superior torque, power and throttle response from tickover to the rev limiter. As an added bonus the inherent muffling effect of the Garrett turbocharger means that the BBR GT270’s exhaust note is more muted than even the factory MX-5, resulting in civilised long distance high speed motorway cruising.
Extensive work by BBR’s technical development team in conjunction with industry electronics calibration specialist EcuTek has allowed BBR to debut a unique suite of ‘Starchip’ calibration software, which offers a greater range of functionality and control for the GT270 owner. With exciting functions including launch control, auto throttle blipper on the downshift and a full throttle gearshift, the GT270’s advanced electronics are designed to enhance performance and offer economy and security functions that far exceed the capability of the standard MX-5.
In detail, the EcuTek ProEcu system on the BBR GT270 offers four driving modes selectable via the MX-5‘s cruise control stalk, which activate the following functions:
BBR GT270 ECU Mode One - 98 Octane fuel maps for every day use (designed for use where fast road driving is the priority for the user.)
BBR GT270 ECU Mode Two - 98 Octane. Features include launch control set at 3800rpm, full throttle/no lift gearshift above 40% throttle, auto downshift throttle blip above 3500rpm (optimised for pure no-compromise circuit driving.)
BBR GT270 ECU Mode Three - 95 Octane cruise map (economy mode for longer motorway journeys.)
BBR GT270 ECU Mode Four - Valet mode, the engine is limited to 3500rpm in all gears (security mode to prevent unwanted third party driver abuse)
With a kerb weight of just 1190 kilos and supercar troubling power-to-weight ratio of 225bhp per ton (144bhp per ton standard), the BBR Mazda GT270 is capable of 0-60mph in just 4.9 seconds, culminating in an electronically limited top speed of 150mph (where permissible.) Courtesy of the substantial torque increase, in-gear acceleration is stunning, making overtaking an effortlessly exhilarating pleasure whether on an A-road, autobahn or a racing circuit.
Cohesive, rapid and understated, the GT270 is the ultimate road legal MX-5, providing the allure of the BBR Mazda turbo pedigree to an all-new audience.
