2006 - 2013 Mazda Miata MX-5 by BBR-Cosworth

The Mazda Miata MX-5 has lived mostly by one trademark since its debut in 1989: offer superior handling with capable performance. From 1989 through 2003, the MX-5 did just that, but in 2004 and 2005, Mazda broke its mold by releasing the turbocharged Mazdaspeed MX-5 in limited numbers. Combined with the revised suspension, the Mazdaspeed MX-5 gave Miata enthusiasts a little extra power to go along with the precision handling of the compact roadster.

When Mazda revamped the MX-5 Miata in the 2006 model year, it gave the Miata a bold look that it had always missed, but it also took away the option to add the famed “Mazdaspeed” badge to the model. For those that want to have their cake and eat it too, BE-Cosworth Cosworth may have the solution for you, in the form of two stages of supercharger kits for your Mk3 and Mk3.5 (2006 through 2013) MX-x Miatas.

Brackley, Northamptonshire, 8th October 2012

Mazda Miata MX-5 by BBR-Cosworth

BBR is delighted to announce some exciting new additions to its successful range of BBR-Cosworth supercharger conversions that offer even more performance options for discerning MX-5 owners. Over the last twelve months BBR has continued to develop its potent supercharger package further, with the twin goals of extracting additional engine power from the iconic sportscar and expanding the fitment possibilities to include all of the 2005 onwards 124 bhp 1.8i and 158 bhp 2.0i Mk3 / 3.5 models. The fruits of this process are now ready to be released, because BBR can now offer two distinct stages of supercharger upgrades with power outputs up to a sensational 258 bhp.

BBR utilises extensively modified Cosworth developed hardware as the basis for the conversions and this in turn, has required a lengthy development process to accommodate the detail differences between the different Mk3 / 3.5 variants. In addition BBR has a revised the crucial engine management side of the MX-5 Mk3 / 3.5 conversion, replacing the ‘piggy back’ Interceptor unit with a Starchip developed remap that optimises the Mazda’s OEM ECU to the engine parameters required for forced induction. This offers a second advantage because customers electing to purchase DIY fitment versions of the BBR-Cosworth conversion can be supplied with a PROECU software/hardware bundle for DIY OBDII port ECU programming and data logging to allow remote installation of the kit for export markets.

Full details on the new BBR-Cosworth upgrades are as follows:

-* Cosworth designed Inlet manifold housing and hardware extensively modified by BBR for optimum efficiency and reliability.
-* Eaton 4th generation MP62 Supercharger
-* Intercooler (Air to water)
-* High flow calibrated injectors
-* High flow replacement air box
-* Competition high-grade hoses and fixings throughout
-* BBR StarChip ECU remap (DIY conversions supplied with ProECu hardware for installation)

BBR-Cosworth Stage One 1.8 SE / 2.0i MX-5 Supercharger Conversion engine performance

Mazda MX-5 2.0i MK3235 BHP / 190 Ib.ft (+77 bhp / +51 lb.ft compared to standard output)
Mazda MX-5 2.0i MK3.5241*BHP / 190 Ib.ft (+83 bhp / +51 lb.ft compared to standard output)
Mazda MX-5 1.8SE MK3 / MK3.5217 BHP / 176 Ib.ft (+93 bhp) / +53 lb.ft compared to standard output)

*The superior peak power on the 2.0i Mk3.5 MX-5 is due to the higher rev limit on this model.

As these dyno proven performance figures prove, the BBR-Cosworth supercharger upgrade substantially increases the 1.8SE and 2.0i’s MX-5’s power and torque – even the smaller capacity model produces a stunning 217 bhp, a mighty 93 bhp more than the base model.

But the peak figures are only half the story of the upgrade, because the BBR-Cosworth supercharger produces performance gains throughout the entire rev range, in a user-friendly smooth, quiet, OEM manner. The huge hike in mid-range torque, instant response from the supercharger and progressive power delivery mean that a BBR-Cosworth supercharged MX-5 1.8SE or 2.0i offers matchless in-gear acceleration and driveability in a way that simply cannot be replicated with normally aspirated conversions using high-lift camshafts and individual throttle bodies.

The BBR-Cosworth Stage One supercharger conversion for Mk3 / Mk3.5 MX-5 models is on sale now, priced at £4995.00 excluding VAT, installed at BBR’s Brackley premises on a ‘drive in – drive out’ basis. The DIY fitment option for export customers is priced at £4295.00 excluding VAT.

ii) BBR-Cosworth Stage Two Mk3 / 3.5 1.8 SE and 2.0i MX-5 Supercharger Conversion Specification

Because performance enthusiasts are always seeking the ultimate upgrade, BBR is happy to oblige with a new BBR-Cosworth Stage Two MX-5 Supercharger conversion. With stunning peak figures of up to 258 bhp and 206 lb.ft of torque, even sharper throttle response and a subtle yet, sporting soundtrack, the BBR-Cosworth Stage Two Supercharger conversion offers near supercar levels of performance and driveability for both the 1.8i and 2.0i variants of the Mk3 / 3.5 models. Ideal for fast road or track day use, this package includes all of the ‘Stage One’ upgrades, but adds key dyno proven BBR components to improve exhaust and intake flow to maximise performance:-

-* BBR stainless steel 4 into 1 exhaust manifold
-* BBR 2.5 “stainless steel exhaust centre section with metallic sports cat and centre silencer
-* BBR stainless steel rear silencer with adjustable 3.5”BBR branded tailpipes
-* High flow BBR performance air filter
-* BBR StarChip ECU remapping to suit Stage Two mechanical specification

The end result is a top quality BBR branded exhaust that manages to produce a pleasant note that’s subtle, sporting and allows MX-5 owners to tackle long distance motorway driving in confidence. Clever design of the 3.5 inch diameter tailpipes means that they are adjustable to accommodate different bumper options or aftermarket bodykits on both Mk3 / Mk3.5 models.

BBR-Cosworth Stage Two 1.8 SE / 2.0i MX-5 Supercharger Conversion engine performance

Mazda MX-5 2.0i MK3252 BHP / 208 Ib.ft (+94 bhp / +69 lb.ft compared to standard output)
Mazda MX-5 2.0i MK3.5258*BHP / 208 Ib.ft (+100 bhp / +69 lb.ft compared to standard output)

*The superior peak power on the 2.0i Mk3.5 MX-5 is due to the higher rev limit on this model.

BBR’s extensive controlled conditions dyno testing proves that the BBR-Cosworth Stage Two upgrade substantially increases power and torque in comparison to the Stage One upgrade. For example, the smaller capacity 1.8i MX-5 produces an amazing 107 bhp gain at 7000 rpm, raising peak power to 231 bhp – approaching double the factory quoted power output of 124 bhp!

The BBR-Cosworth Stage Two supercharger conversion for Mk3 / Mk3.5 MX-5 models is on sale now, priced at £6395.00 excluding VAT, installed at BBR’s Brackley premises on a drive in – drive out basis. The DIY fitment option for export customers is priced at £5455.00 excluding VAT.

Hey! I drive a 2004 Mazdaspeed Miata, and I consider myself to be rather "manly" lol. Actually I say I am more manly because I am man enough to drive one smiley.

Thanks for reading!

yes brad, you got that right. as men, we want to show off and come off corners in clouds of smoke and smell of burning tires.

so in opposition to that, a man’s car would be something quite rough, with sharp edges and lots of power, coming out smoking out of every corner?

brad, this car is pinned as a girl’s car because it has soft lines, it’s gentile and it handles remarkably. it didn’t use to go fast and it was lots of fun. that’s why.

why do you guys pin it as a girl’s car? it isn’t that girly.

this is a car you’d wand your wife to have so you could have fun in it.

i always loved the miata. now i love it even more.

tweak the suspension and you’ve got yourself one hell of a car.

i hope this power-ups don’t ruin the miata’s handling. it would be a shame if it would.

the miata, with these up-grade kits, goes to bmw z4 land. and it wouldn’t be any wonder if it kicked ass.

the miata has always been a car you would want your girlfriend to have so you could drive it.
