The new Super 225 package boosts the third-generation 'NC' model to 224 horsepower.

Tuning firm BBR has announced a new "Super 225" package that applies modern tuning technology to the 15-year-old third-generation Mazda MX-5. The company, which is based in Brackley, Northamptonshire, says the new upgrade is "the ultimate no-compromise intake package" for "hardcore" enthusiasts.

Unlike many of BBR’s upgrades, the new Super 225 pack does not require the addition of a turbocharger to the MX-5’s normally aspirated 2-liter petrol engine. Instead, the package builds on the Super 200 conversion by improving the engine inlet efficiency, allowing an increase in power, torque, and throttle response.

Under the hood, BBR has fitted a new exhaust manifold, new camshafts, and branded tailpipes, as well as a few smaller additions. Together the tweaks deliver an extra 67 horsepower over the standard 2-liter engine, bringing the total to 224 hp, while an extra 36 lb-ft (49 Nm) of torque takes the headline figure to 174 lb-ft (236 Nm).

BBR has retained many of the standard car’s features, with no changes to the engine bay, the engine electrical network, or any of the safety systems, so BBR says the engine can be returned to stock specification if owners so wish. The car also meets the UK MoT emissions requirements and can run on 95- or 98-octane fuel.

Despite the changes, BBR says the in-cabin noise is still “acceptable” for normal use, and the changes to the engine make the car suited to both track driving and urban environments. However, the company does suggest fitting its optional air filter for “everyday use.”

Those wishing to purchase the Super 225 kit can do so in a number of ways. Drivers with standard cars can spend £3,495 plus VAT on a DIY kit, or £4,295 plus VAT on a drive-in, drive-out installation at BBR’s Brackley headquarters. If, on the other hand, a customer already has the Super 200 kit installed on their vehicle, BBR will sell and fit the extra components for £2,495 plus VAT.

The kit is also compatible with the smaller 1.8-liter engine fitted to some third-generation "‘NC" MX-5s, and can also be applied to vehicles equipped with aftermarket 2.3- or 2.5-litre engines. And BBR says it will eventually launch similar packages for earlier and later versions of the MX-5, which last year celebrated its 30th birthday.

"The main challenge for our development program was optimizing the intake side of the engine by switching to bespoke independent throttle bodies (ITBs) while retaining the standard Mazda Denso engine management system and under bonnet layout,” said BBR’s Neil McKay. “Even the OEM front strut brace remains in situ (where fitted,) and the conversion is fully reversible to stock in future should the owner decide to do so.”

Brackley, Northamptonshire, 25th June 2020

Renowned for its legendary turbocharger conversions since 1990, UK based Mazda tuner BBR is now pleased to announce an exciting engine tuning upgrade for all 2005 onwards 2.0-litre MX-5 / Miata Mk3 / 3.5 / 3.75 (NC) models, which delivers the ultimate ‘no-compromise’ intake package for hardcore normally-aspirated performance enthusiasts.

Called the ‘Super 225,’ the new upgrade builds upon the success (and much of the mechanical hardware) of BBR’s popular Super 200 conversion for NC models of the Mazda MX-5 / Miata by dramatically improving the engine’s inlet efficiency to deliver a serious hike in power, torque and throttle response. Boasting a gain of 67 bhp and 36 lb.ft of torque, the Super 225 package transforms the NC MX-5 / Miata into a car that can very much punch above its weight whatever the situation, with a stimulating soundtrack to match.

Converting the MX-5 NC’s MZR LF-VE 2.0-litre engine to this level of normally aspirated created several challenges for the BBR technical team.  “The main challenge for our development program was optimising the intake side of the engine by switching to bespoke independent throttle bodies (ITB’s,)” says BBR’s Neil McKay, “while retaining the standard Mazda Denso engine management system and under bonnet layout.” Retention of the OEM CANbus networks and vehicle safety protocols is a high priority for BBR, so a switch to dedicated stand-alone engine management was never an option. Similarly, bodywork modifications to provide clearance for engine tuning packages works against BBR’s OEM under bonnet appearance goals, while clever design means that the package is compatible for both LHD and RHD NC models. “Even the OEM front strut brace remains in situ (where fitted,) and the conversion is fully reversible to stock in future should the owner decide to do so,” says McKay.

“To maximise performance the OEM Mazda MAF sensor and plenum chamber are dispensed with for the Super 225 conversion, but the original factory drive by wire throttle configuration is retained and integrated into the BBR independent throttle body set up. Here is where BBR’s close partnership with EcuTek enabled us to develop an ECU calibration to accommodate this new hardware, which entailed a considerable amount of dyno time and road testing to accumulate mileage and refine the end package,” McKay comments.

Mechanically, carefully designed packaging of the 45mm direct to head billet alloy DCOE independent throttle bodies combines with alloy inlet ram pipes which boast dyno tuned lengths and a curved form factor to avoid bodywork alterations, while delivering maximum possible brake horsepower at an engine safe 7500-7800rpm

The end results are a mighty 224 bhp (225 PS) at 7550 rpm, combined with peak torque of 174 lb.ft at 5950 rpm. Over 170 lb.ft is available from between 4000-6000 rpm, with more than 150 lb.ft on tap from just 3000 rpm all the way up to the 7800 rpm rev limiter - highlighting the user-friendly nature of the conversion that is everyday driveable and ideally suited to town, touring and track days. In-cabin noise is acceptable for regular driving and motorway use, with a distinctive, addictive intake ‘bark’ being produced under wide open throttle acceleration.

Careful development by BBR has ensured that despite the significant performance hike the Super 225 upgrade is fully UK MOT emissions compliant and can run on either 98 or 95 octane fuel, while an optional BBR air filter is advisable for everyday use.
