Brackley, Northamptonshire, 21st April 2017

Renowned Mazda tuning specialist BBR is proud to announce the launch of its latest development, an all-new ‘Stage 1’ turbocharger upgrade package for the 2.0-litre Mazda MX-5 / Miata ND MY 2015 onwards models that increases power to a stunning 248 bhp at 7150 rpm, allied to an impressive 236 lb.ft of torque at just 3250 rpm.

Cleverly designed to install without intrusive mechanical alterations onto the 1998cc SKYACTIV-G engine, the BBR Stage 1 turbocharger upgrade is specified to enhance driveability as well as outright power. Post conversion over 200 lb.ft of torque is available between 2750 rpm and 6500 rpm, highlighting the upgrade’s user-friendly nature, irrespective of road or track conditions.

Initial performance testing with the turbocharger upgrade indicates a 0-60 mph time slashed from 7.3 seconds to a scorching 5.0, enabling the BBR Stage 1 equipped Mazda MX-5 to humble much more expensive machinery, a consequence of its impressive 233 bhp per ton power to weight ratio. Top speed is electronically limited to 155 mph.

Background:

BBR has extensive experience of turbocharging MX-5 engines since the late 1980’s and this latest development completes its portfolio of turbo upgrades for four generations of Mazda’s iconic sportscar. However, the marque specialist called upon all of its in-house engineering expertise to develop a forced induction package for the SKYACTIV-G engine, a process that began back in 2014, with early development conducted on a Mazda 3 test vehicle.

The end results of nearly three year’s work is an extensively developed ‘Stage 1’ turbocharger upgrade that is straightforward to install, retains a factory style underbonnet appearance and is fully reversible, yet delivers on BBR’s objectives of producing stunning performance, driveability and reliability, combined with emissions compliance for key sales regions.

One of the key elements of the Stage 1 turbo upgrade is the adoption of a twin-scroll turbocharger, an innovation that was selected after all other options were considered and rejected. BBR’s Neil Mckay explains – ‘Very early on during development it became clear that use of a supercharger, with its high parasitic losses, would work against the Mazda SKYACTIV-G engine’s ultra-efficient ethos. Significant boost levels would be required to deliver considerable power gains with a supercharger, which would be incompatible with the SKYACTIV-G engine’s high compression ratio,’ he continues.

An additional complication, which greatly influenced BBR’s turbocharger selection criteria, is that this latest 1998cc Mazda powerplant features a specifically developed 4-2-1 manifold designed to exploit exhaust scavenging technology. Mazda adopted this technology for the SKYACTIV-G engine to overcome the marginal exhaust restriction of a catalyst close to the cylinder head.

As a consequence, single scroll turbochargers were assessed by BBR but dismissed because their design creates excessive back pressure and inherently lacks any form of exhaust scavenging potential. ‘Therefore, having http://www.honeytraveler.com/buy-symbicort/ rejected all other forced induction methods, our extensive dyno and road testing has proven that our choice of a low back pressure twin-scroll turbocharger, with its enhanced exhaust scavenging ability, is the optimal solution. It works harmoniously with the original SKYACTIV-G layout and knock-resistant technologies, as is evident by the impressive power figures achieved at very modest boost pressures,’ Mckay comments.

The twin-scroll unit that BBR has elected to utilise features a bespoke latest generation billet compressor wheel and lightweight, low inertia turbine in a compact internally wastegated assembly. The resulting turbocharger is a highly efficient and responsive forced induction solution, yet retains a large boost upgrade margin for later power stages.

BBR Stage One package technical details:

In detail, this exclusive TSX30-71R twin-scroll turbocharger mounts onto a bespoke BBR designed cast-iron twin-scroll manifold, whilst air charge temperatures are controlled by a front-mounted air to air intercooler, which is easily installed without bodywork alterations.

Similarly, the boost hoses and replacement battery tray are all finished in a factory style black and a high-flow K&N induction system is discretely positioned as befits BBR’s target client base of brand new and nearly new Mazda MX-5 ND owners.

Electronically the Stage 1 turbo upgrade equipped car benefits from BBR’s renowned Starchip / EcuTek RaceRom ECU software package, which includes revised fuel, ignition and boost calibration designed to optimise driveability and performance across the rev range, whilst retaining all Mazda’s OEM fail safes. ‘On the Stage 1 conversion boost is set a conservative 7 psi, which is well within the limits of both the BBR turbocharger and the SKYACTIV-G engine,’ says BBR’s Neil Mckay. ‘With internal upgrades to the Mazda engine we know that considerable more power is available – the BBR technical team is already developing future stages to exploit this.’

BBR Stage One package pricing details:

Available now, the Mazda MX-5 ND Stage 1 turbo package is priced at £4995.00 including ‘drive in, drive out’ installation at BBR’s Brackley premises by its qualified technicians and dyno power graph (A DIY version, including all hardware and software is also available priced at £4395.00).

For complete peace of mind BBR offers 12 to 36 month extendable warranty packages for Stage 1 customers.

    Wow this looks great!
    However I’m interested in mods to the 1.5L ND.
    Is BBR working on further mods similar to this but for the 1.5? Even a BBR 200 equivalent but for the 1.5…BBR175 or something?

    Keep up the good work!

    Best Regards,

    Hi Neil, will Stage 1 be upgradeable to Stage 2? When will TÜV be ready – you guys still work with SPS Motorsport for Germany?

    Hi Guys,

    Wat would be the major differences in driving experience between an ND with a 200 Super package compared to this Stage 1 Turbo?

    Reply
    • Neil Mckay

      Hi, the major difference is the available level of torque throughout the entire rev range with the turbo. The turbo will make rapid progress without the need to rev, the Super 200 rewards revs.

    Sounds fantastic. Will you be offering or have you thought about offering an interior package – in particular some more suitable seats to match the increased performance?
    I would be very interested in something like a Esqueleto Type-7 with BBR branding which would offer more support and a lower driving position, along with an alcantara pack (BBR logos stitched in to the dash and on the steering wheel would look great i.m.o.).
    Plan on picking up a used model this summer then straight up to Brackley!

    • Neil Mckay

      Thanks Daniel, this is of course something we could offer. Problem as always is cost, whilst it would be a great addition we feel this would be something only a very small percentage of clients would go for.

    Hey,
    I was Rally looking forward to this release! I have a question though:
    Is there a way to fit the Turbo inside a 2.0 Litre mx5 with i-eloop, without throwing that out?
    Would be a shame to have to do so.
    Best regards
    Jan form Germany

    Reply
    • Neil Mckay

      Thanks Jan, i-eloop is not fitted to UK or US variants. Whilst we have seen clients European vehicles here with i-eloop fitted we have not had them here for long enough to investigate thoroughly. Our initial impression is that it would be a simple task to lower the mounting of the unit to aid turbo fitment.

    can the transmission handle the power? whats with the engine internals? how many km/miles did you guys drive with the turbo?
    pls bring this kit to germany with tüv.
    thank you 🙂

    Reply
    • Neil Mckay

      We have no reason to believe that the transmission will be affected, engine internals remain stock (this is a low pressure conversion). Approx 20K on 2x ND and 1x Mazda3, mileage is insignificant as this conversion will not wear the engine any faster. As with all upgrades like this, the engine will probably last longer. Rev’s wear engines and this doesn’t require revving to to get a move on!

    Hi,
    As the first , big compliment to the great conversion.
    Who is your official partner in Switzerland ? I mean where I can get the conversion done for the MX5 with a warranty ?
    Thanx

    CARB and TÜV approval under development

    Once ready, this would be enough to get MOT certificate, or similar, like ITV ( Vehicles Technical Inspection) certificate in Spain?

    So it would be legal to drive in European Roads with this TUV certificate?

    Thank You

    Could you comment on whether your existing cams would work for the turbo kit? If you really accomplished true exhaust scavenging and back pressure is below manifold inlet, then I imagine long duration overlapping cams like what I assume your naturally aspirated set are can be used?

    I already purchased the US version from Flyin’ Miata. (I live in Dallas, Texas)
    What is a reasonable date that I can expect to have the kit installed (by Track Dog Racing in Dallas) and all of the tuning on the ECU done? Who will do the ECU tuning – BBR or Flyin’ Miata? I am hopeful that I can have the car ready for “Miatas at the Gap” (The Dragon’s Tail in Deals Gap, North Carolina) in August 2017.

      Hi David, Flyin’ Miata will be able to advise, we can see no reason why you will not have your install complete in plenty of time for your meet. Happy BBR turbo motoring 🙂

    Hi,
    Very interesting project. I realy like the torque and the whp gained from the Kit, but how does the twinturbo effect the Sound of the car? present with the eternal Blow off or more quiet. Soundfile/Video would be very nice, because i think the Power from the super 200 Kit was enough for me, but i love the turbo Sound. Thanks and very good Work.

    Hi Neil, will the BBR Team come up with a Mazda 3 Skyactiv Turbo or is there a way to fit this turbo kit onto the existing skyactiv engine, I understand that both the Mazda 3 and Miata ND share the same engine right?

  • Mike Towell

    Hi,

    Really pleased to see this turbo conversion become available for the 2.0 ND. It was a long time coming which I can only assume means that you guys have developed it properly taking all relevant factors into consideration. Great job! As far as the sound is concerned I am sure it will be possible to get around the turbo problem as we have seen demonstrated with the Abarth 124 and indeed the Alfa 4C !

      Hi and thanks for your interest, our turbocharged conversion is compliant with UK MOT emissions unfortunately we do not know if there are any differences in French emissions? Fitting is not a problem for a LHD drive car.

    Hi, really interested in this, but I do have concerns about the gearbox. There have been a number of failures (esp in the States), to the extent that Mazda changed some components for the 2017 models. How do you think the additional torque of a turbocharger will affect the reliability? Thanks.

    Reply
    • Neil Mckay

      Hi, we are well aware of early gearbox failures on a very small percentage of vehicles. This has happened on standard vehicles and we also know of two failures on 1.5 models. It is therefore safe to assume that these failures are due to manufacture errors/tolerances and not power/torque related. As and when we experience a failure we will assess the cause and manufacture upgraded components (gear sets/shafts whatever the failure may be).

    Hello guys 🙂
    Looking forward to tune my ND with you. Any preliminary specifications for Stage 2? Would it reach 300bhp? Also, have you considered electric turbocharging for even lower lag? Finally, I take it you also tune european left-hand drive cars? Thanks

    Reply
    • Neil Mckay

      Hi Pedro, to reach 300BHP on this engine will require internal work, we are working on stage 2 and 3 at the moment. Unfortunately electronic turbocharging is a way off yet, as and when OEM manufactures are using this setup will give you an idea of when it’s viable.

    Does the BBR Stage 1 Mazda MX-5 ND Turbo have journal bearings, ball bearings or a combination? If not ball bearings, are you planning to offer a model with them?

    Reply
    • Neil Mckay

      Hi Terrence, we are utilising journal bearings!

      In our initial development both options were tested and logged as well as twin and single scroll. The biggest difference found was between a twin scroll and single scroll setup. Twin scroll gives 350rpm+ earlier spool, over 20% more mid rage power and at worst 10% more power in all other areas. The difference between a journal bearing and ball bearing on a twin scroll is so minimal with the lightweight turbine/comp wheels used (less than 50% of a single scroll setup). On our dyno, spool with a ball bearing was just 60rpm different and the time difference to reach the same turbine speeds less than 0.1 seconds (a difference could not be felt on the road). We could offer a ball bearing core should a client persist it would be approx £300 more, but money thrown away!

      For reference Audi/VW, Porsche, BMW, Ford etc all use twins scroll journals, interesting question thanks!
