BBR NC SUPER 175
(1.8-litre NC models only) +39bhp & 16lb.ft
*Fully MOT Compliant with the inclusion of new 4-1 long primary catted manifold
BBR’s Super 175 normally aspirated tuning package for 2005-2015 Mazda MX-5 1.8 models.
The BBR ‘Super 175’ DIY upgrade for the 1.8i Mazda Mk3 / 3.5 and 3.75 MX-5 (NC) models consists of the following components:-
- Specifically designed to meet the demand for a value for money engine upgrade that delivers extra response, power, driveability and excitement, BBR has achieved power gains that were previously impossible using conventional normally aspirated tuning
- Gains an incredible 39 bhp & 16 lb.ft of torque, with power increases throughout entire rev range
- A thoroughly developed and well proven package that gives 1.8 MX-5 owners power levels beyond 2.0 models without going for our turbocharged conversions.
- For everyday use, offering exceptional value for money
BBR GTi have noticed that there is a significant amount of customers that would like more than just an exhaust and software upgrade to improve performance of their 1.8L, without going all out on a BBR turbo conversion. The BBR Super 175 upgrade is dyno proven to boost peak power to a genuine 175 bhp at 7300 rpm, a remarkable tested gain of 39 bhp.
However, the Super 175 kit’s headline numbers only tell half of the story of the appeal of the new BBR package, because the spread of power is equally important. As a consequence diligent development by BBR has resulted in a pair of exclusive camshaft profiles with unique lift and timing specifications. These camshafts profiles are the result of extensive testing and combine with BBR’s 4-1 exhaust manifold plus extensive engine management recalibration create a package that delivers strong gains from just 3000 rpm upwards – standard power output is exceeded at every point in the rev range, making the Super 175 upgrade both a user-friendly and exciting prospect.
Similarly BBR has placed great emphasis on extracting more torque from the MX-5’s 1.8-litre, 16-valve powerplant to ensure that driveability and throttle response are superior to the stock car in all driving conditions. Highlighting the flexible performance of the upgrade, the BBR Super 175 equipped 1.8 MX-5 produces 144 lb.ft of torque (16 lb.ft more than the original,) with the peak figure arriving at just 4750 rpm, no later than the standard vehicle.
Mindful of both costs and occupant comfort for high speed, long distance driving, the standard exhaust centre section, catalytic converter and rear silencer are retained with the BBR Super 175 upgrade, but the package includes a set of 3.5 inch branded stainless steel tailpipe trims which are adjustable to accommodate different bumper options on Mk3 / 3.5 / 3.75 models. In addition, exclusive yet subtle BBR wing and bootlid badging is included in the Super 175 upgrade.
Careful development by BBR has ensured that the Super 175 package is fully UK MOT emissions compliant and will run on either 98 or 95 octane fuel, with all the existing Mazda electronic fail safe systems untouched and fully functioning on converted cars.
On the road the extra torque, power and throttle response from the BBR Super 175 combine to produce an upgraded Mazda MX-5 which feels much quicker and far more willing, eager and exciting to drive than ever before – whatever the traffic, weather or road conditions.
1) An optional manifold back BBR 2.5 inch stainless steel centre section with integrated sports cat and BBR ‘Supersport’ or ‘Grand Tourer’ silencer is available for an additional performance gains.
2) As from July 2021 BBR 3.5 inch diameter branded tailpipes with stainless steel clamps (previously included) are no longer included with this conversion due to vehicle age and difficulties removing the OEM rear silencer.
