BBR teams up with Cosworth to give MX-5 added punch

The little Mazda MX-5 is a true modern classic. For over 20 years it has been adored by critics and buyers across the globe. Built from an old skool perspective where handling is more important than outright power, many have often felt the MX-5 could do with some more grunt.

The latest tuner to try its hand at doing just that is BBR GTi who have invited Cosworth to the party, as well. The BBR-Cosworth soiree found an extra 77bhp to throw at the current model NC MX-5 courtesy of an MP62 Eaton supercharger. That’s a massive 117kW 57kW in our lingo! Torque has also been given a boost, to the tune of 69Nm.

Importantly, BBR say the handling balance of the MX-5 has not been altered. Well, they would say that, I guess. The cost for the kit is £4995 (approx AU$8100), so you’d want to hope they’re right.

If you drive an older NA or NB MX-5, well, fear not as BBR have a 220bhp turbo tuning kit to help you along too.
