And it's still naturally-aspirated.
The Mazda MX-5 Miata is possibly one of the most loved sports cars of all time. These little two-seater sports cars have gone through four generations and multiple special editions, and even motoring royalty such as Christian von Koenigsegg take inspiration from these tiny sportsters. But as always, the motoring community will try and improve on what is already an impressive platform. In this case, we're talking about the NC Miata; the ugly stepchild that never really found its place amongst Mazda enthusiasts.
Its frog-like looks and heavier weight meant that hardcore MX-5 enthusiasts never really got into them as a tuning platform, but BBR Performace in the UK has developed a new kit that should swing opinions the other way.
British Mazda Tuners BBR has recently unveiled a new tuning package for the Mazda NC, the third generation car produced between 2005 and 2013. Interestingly enough this performance kit, which focuses on the powertrain, does not resort to the standard turbocharging route, but keeps the engine naturally-aspirated. As the name would suggest, the package raises the standard power output to a usable 225 hp (it's actually 224 but who's counting) which is a whole 67 hp more than standard.
All this is accomplished without sacrificing throttle response or general drivability, which is a difficult task when you're not playing with forced induction.
So what has been changed? Well, first of all, BBR has added an individual throttle body system for a massive improvement in airflow, and the best part is that it doesn't require any modifications to the MX-5's factory engine management system. This setup is matched up with the obligatory set of lumpy camshafts and ram air intake pipe. A free-flowing exhaust bolts up to the other end of the head which is connected to Mazda's standard mid-pipe and muffler and is finished off with a pair of new 3.5-inch tips.
The end result is a power figure of 224 hp at a heady 7,550 rpm and 174 lb-ft of torque kicking in at 5,959 rpm. The package will set you back around $4,330. BBR also offers chassis modes such as strut bracing and performance brake upgrades. That should be enough to stick with a stock Honda S2000 around the track.
