The highly acclaimed BBR Stage Two Mazda MX-5 NC (2005-2015) turbo upgrade 

For MX-5 enthusiasts who demand even more performance than delivered by the BBR Stage One conversion, the BBR Stage Two Mazda MX-5 (2005-2015) turbo conversion is available. Clients who have chosen this conversion agree that it delivers astonishing performance with enough power to see 135i BMW’s, Boxster S’s etc. getting gradually smaller in the rear view mirror!

During our 2013 development, it became apparent that there was significantly more potential to be unleashed from the standard Mazda drivetrain than that achieved by the stage one conversion. The addition of an uprated clutch assembly allied with tried and tested BBR performance hardware enables our stage two conversion to cross the magic 300bhp barrier reliably whilst still maintaining (engine safe) low boost pressures.

Dyno testing has shown that the BBR Stage Two Mazda MX-5 turbo conversion produces a stunning 302bhp at 7350rpm with a mighty 254lb.ft of torque available at 4950rpm and an incredible 270bhp at the rear wheels on 2.0-litre models. These figures are achieved whilst still running very low and safe boost pressures of 0.65bar (9-10psi). In a car weighing around 1100 kilos, BBR Stage Two turbo conversion catapults the MX-5 firmly into supercar territory. On a 1.8-litre models, the figures are 264bhp and 232lb.ft of torque, endowing even the smaller engined MX-5 with fearsome pace.

For an idea of the fun provided by this conversion which offers 300bhp (30bhp more than our GT270 new car package), please view evo magazines BBR GT270 v Toyota GT86 TRD tack battle:

For clients who are looking for more than 300bhp, 14psi is where the serious fun starts! Our turbocharger and hardware supplied in our stage one turbocharged conversion is capable of 260-360bhp. Uprating the standard MX-5 engines pistons and rods for forged items (as well as crankshaft in earlier MK3 models) allows us to safely exceed 10psi of boost pressure.
