Make no mistake, the Mazda MX-5 is one of our all-time favourite cars. The Japanese interpretation on the British roadster deserves every one of the accolades which have helped to make it one of the world's best-selling convertibles.

However, there's always been that nagging feeling that the compact wonder could have done with a little more power to compliment that heavenly rear-wheel drive, front engined layout.

Well, a tuning firm from Northamptonshire has now solved that problem by introducing a range of forced induction kits that dramatically increase the performance of each generation of the slender MX-5.

BBR, based in Brackley, has teamed up with Cosworth Engineering to launch a supercharger conversion for the latest version of the best-selling convertible which pushes the 2.0-litre engine's output from 158bhp to 235bhp at 7130rpm.

The company insists the 77bhp gain is delivered in such a progressive way that the MX-5's delicately balanced handling remains intact without any need to upgrade the chassis.

The package, which costs £4,995 including fitting, features the latest Eaton supercharger mated to a Cosworth designed inlet manifold.



The Brackley based tuner also makes turbocharger kits for the 1.6-litre and 1.8-litre engines featured in the Mk1 and Mk2 MX-5s.

Based around a Garret GT25 turbo, the £4,995 Phase One package extracts an impressive 220bhp from the smaller capacity engine.

For £2,500 more BBR will also completely renovate a Mk1 MX-5 with bigger brakes, a limited slip differential, bigger alloys and a longer final drive to make the extra power more accessible on the motorway.
