Power to the People: BBR-Cosworth Supercharge Mazda MX-5 to 235HP

Owners of the latest generation MX-5 / Miata seeking more oomph from Mazda's best seller will be happy to know that BBR has joined forces with Cosworth Engineering to develop a supercharged conversion package for the 2.0-liter version. The BBR-Cosworth collaboration for the Mk3 2.0-litre MX-5 focuses around a fourth-generation Eaton MP62 supercharger mated to a Cosworth designed cast integral inlet manifold, which is said to be optimized for both performance and fuel economy - although we'd take the latter with a grain of salt.
In stock form, the MX-5's 2.0-liter naturally aspirated powerplant delivers 158-horsepower. After the implementation of the supercharger and Cosworth's inlet manifold, output is lifted to a dyno proven 235 bhp at 7130 rpm, with a healthy 190 lb.ft of torque available at 5260 rpm. That's an increase of 77 bhp and 51 lb.ft over the standard model.
The company said the fitted price for the BBR-Cosworth Mazda MX-5 Mk3 supercharger upgrade kit is set in Britain at £4,995 (approx. US$7,750). BBR added that it will also be supplying BBR-Cosworth kits for DIY fitting, complete with all options and full installation instructions, but the tuning house has not yet released pricing.
