BBR introduces an MX-5 Miata Stage 1 upgrade
BBR’s new Stage 1 package for the current Mazda MX-5 delivers huge output and performance improvements.
In standard guise, the roadster’s normally-aspirated 2.0 litre engine produces 157 bhp (118 kW / 160 PS) and 200 Nm (147 lb/ft) of peak torque. With the latest BBR modifications, those figures rise to 248 bhp (185 kW / 251 PS) and 320 Nm (236 lb/ft).
To achieve such colossal increases, BBR resorted to forced induction. According to the company, “Very early on during development it became clear that use of a supercharger, with its high parasitic losses, would work against the Mazda Skyactiv-G engine’s ultra-efficient ethos.
“Significant boost levels would be required to deliver considerable power gains with a supercharger, which would be incompatible with the Skyactiv-G engine’s high compression ratio.
“Therefore, having rejected all other forced induction methods, our extensive dyno and road testing has proven that our choice of a low back-pressure twin-scroll turbocharger, with its enhanced exhaust scavenging ability, is the optimal solution. It works harmoniously with the original Skyactiv-G layout and knock-resistant technologies, as is evident by the impressive power figures achieved at very modest boost pressures.”
As well as a TSX30-71R turbocharger, the conversion includes a carbon fibre heat shield, a bespoke cast iron manifold, a stainless steel downpipe, an aluminium air-to-air intercooler, Starchip / EcuTek RaceRom ECU recalibration and K+N’s Typhoon high-flow intake system.
Consequently, the 0-60 mph (96 km/h) time drops to 5.0 seconds, while top speed is electronically limited to 155 mph (250 km/h). In other words, the turbocharged MX-5 is significantly faster than a stock Abarth 124 Spider.
BBR says that emissions remain MOT-compliant, plus CARB and TÜV approvals are being sought. Furthermore, the alterations are fully reversible.
In the UK, the Stage 1 upgrade costs £4,395 in DIY kit form, or £4,995 fully fitted (both prices exclude VAT). It’s also being offered in the USA via distributor Flyin’ Miata.
Of course, Stage 1 might not be sufficient for some MX-5 owners. For them, Stage 2 enhancements should be available later this year.
