It took BBR just over 11 months of intensive development to remove key electronic and mechanical restrictions of the Mazda3, Mazda6, CX-3 and CX-5 models, unleashing the naturally aspirated four-cylinder engine’s full potential.
As mentioned above, two stages of tuning are available – the BBR Super 170 and BBR Super 185. The numbers denote its final power output, achieved via BBR’s Starchip ECU software package that is programmed to revise fuel and ignition calibration. This optimises engine performance from 2,000 rpm to 7,000 rpm limiter, and it also removes electronic throttle restrictions for a more spirited driving experience.
Final output figures for the BBR Super 170 package is 169.7 horsepower at 6,300 rpm and 221 Nm of torque at 4,250 rpm. Not too far off from the Malaysian-spec 162hp and 210 Nm, and you most certainly won’t pay £499 (RM3,324 excluding taxes) for the small performance bump. However, the BBR Super 185 package might be worth considering.
This upgrade package builds on top of the Starchip ECU, but the engine will need to breathe better to gain an additional 15 hp. For £1,795 (roughly RM12k), you get a stainless steel 4-2-1 exhaust manifold and a cold air induction system featuring K&N high-flow filter. This results in an output of 185 hp at 6,300 rpm and 235 Nm of torque at just 4,000 revolutions.
To complete the package, BBR is also offering a 2.5-inch diameter centre section with high-flow sports catalyst (EU emissions compliant; £495 or RM3.3k) as well as a stainless steel BBR-branded rear silencer (£395 or RM2.6k) that produces a sportier exhaust note. Other upgrades include BBR Sport Springs with Koni adjustable dampers for £195 (RM1.3k) and £605 (RM4,000) respectively.
