BBR wrings 213hp from 1.5 MX-5
Famed Mazda tuner finally turns its attention to the smaller-engined MX-5, with predictably agreeable results
Now BBR is offering a 'Stage One' conversion for the 1.5-litre engine, which uses a twin-scroll blower to elevate the downsized motor's output from a worthy 131hp to a downright lively 213hp. No less enticingly, peak torque climbs from 111lb ft to 197lb ft - with over 150lb ft available from 3000rpm.
"For the 1.5-litre SKYACTIV-G engine, the main development effort focussed on turbo matching to suit our desired twin goals of transforming the everyday driving performance, whilst maintaining the rev-free nature of the smaller power unit," explained BBR GTi Ltd Managing Director, Neil McKay.
The company's exclusive TSX28-67R turbocharger is mounted onto a bespoke, cast-iron, twin-scroll manifold with the air charge temperatures controlled by an air-to-air intercooler that apparently doesn't require any bodywork alterations to install. Along with all the associated hoses and a high-flow K&N induction system, BBR also adds its Starchip/EcuTek RaceRom ECU software package.
'On the Stage 1 conversion boost is set at a conservative 7 psi, which is well within the limits of both the BBR turbocharger and the SKYACTIV-G engine,' added McKay. 'With internal upgrades to the Mazda engine we know that considerably more power is available - the BBR technical team is already developing future stages to exploit this.'
If the package is of interest - and we can't think of an earthly reason why it wouldn't be - the firm will complete a 'drive in, drive out' installation at its own premises for £4,995. Alternatively, you can do it yourself for £4,395. An extendable warranty is also available. More details can be found here.

Happy to be educated.
2.0 comes with billsteins IIRC so might be a better platform.
I got a BBR turbo fitted with about same power as this, 230-240bhp and left it mainly the same, no brake upgrade, no suspension and it works fine. I did get a Quaife LSD fitted which helps a lot pulling out into junctions and also doughnuts but any time gained when spanking it is marginal on the road. When you get to that level a spinning inside wheel is perhaps slightly safer rather than 1.1s saved on the Bxxxx. Trackdays different of course. I did track days in mine, the brakes are fine, if your wife is finding brake fade and issue on a track day with them with the extra power of the BBR conversion then just do smaller stints. Perhaps buy overpriced pie and chips whilst everything cools down........
It's a bit odd people on PH always complain cars are too grip and electronic nanny bias and then when given counter this,complain you could not drive it unless you give it lots more grip. Er? Sounds great fun to me.
I do have a couple of points though.
1. My NC BBR conversion looks very linear on the dyno. The peak on this between 3 and 4k looks pretty steep, this is either a good thing fun wise, or a good thing scary wise. I'll be looking forward to the first test reports...
2. TSX28-67R ? So it's not a Garrett then? BBR have gone all Mclaren Automotive on us, I blame that German F1 team they mingle with whilst buying Ginsters pies down at Tesco's Comment Neil?

£2125 - which shows that blowing air for fun is not inexpensive....
195's might be a bit lively but the 205's will be absolutely fine.
Nobody complained about the Sierra RS500 Cosworth on 1980's tyres saying 205's were not appropriate back in the good old days....
We want cars "a bit lively" but not too fast so you get locked up. Or if you do have a mishap with it just sticking out of the hedge rather than half way across the farmers field.
PH, please can you correct the prices in the article to reflect the VAT status of those price?
I find it all deeply uninspiring. I like the new mx5 a lot, I just wish someone would do the right thing and give it a proper going over. It's like actual engine tuning is a thing of the past. Everything must be all things to all people, which ultimately just makes things boring. Low down torque? Mid range shove? Might as well have a diesel.
