Mazda Eunos Roadster: PH Fleet
Haters of open top Mazdas look away now, there's some more MX-5 love coming your way

There's the small matter of pumping four times the car's purchase price into a power upgrade of course. But since when did logical arithmetic like that come into such decisions.
If I'd ever doubted the scope and taste for modification among my fellow Mazda owners popping along to a Goodwood track day co-organised by in-house MX-5 nut James Hayward as a Mission Motorsport fund-raiser opened my eyes. There were MX-5s with superchargers, MX-5s with turbos, MX-5s with ludicrous aero, MX-5s with ludicrous wheels and - in a couple of cases - MX-5s that seemed to have all of the above.
Now, I enjoyed the BBR car hugely and likewise the lurid 787B celebration Le Mans edition NA I drove for a PH Heroes piece a while back. And it's claimed that original turbo kit remains the best-selling aftermarket turbo upgrade ever sold, BBR shifting over 1,000 back in the day.
Would I put a turbo on my Eunos? Not sure I would. In my introduction to the BBR piece I alluded to the kind of purists who might see forced induction as not in keeping with the MX-5 raison d'etre. I'm possibly one of them but that argument was tested by the GT270 and as a package Neil's car was a blast. But I rather like mine as it is, meagre power output or not. The beauty of the MX-5 is that there are so many around and they're so cheap and easy to play with that each can do to their own and I'd never dare to opine on what's right or wrong. And with my bright orange wheels, frame rail stiffening, Performance 5 suspension and cast-off 'hybrid' exhaust system I can hardly claim purist points for my own car.
Hayward's car is very much to his taste and further down the track route than I'd want for my Mazda but I did enjoy trying out his Omex throttle body equipped car around Goodwood. Were I to look for more power out of my car this is probably the route I'd go, even if the raw numbers - around 150hp against BBR's Anniversary 221hp from the turbo - are somewhat less impressive. It sounds mega though, the high-rev howl more in-keeping with the traditional twin-cam vibe for my money. As I say though, each to their own.
It'd still be an investment of more than the car's value (£2,395 including VAT and Omex ECU) for a few more horsepower and, frankly, not especially high on my list of priorities right now. It's a couple of months back now but the buzz from that Goodwood track day I did with mine still hasn't subsided one bit, the lead photo above printed out and pinned above my desk as a reminder of why smiles per hour count more than chasing extra mph or bhp in my book. An honourable standpoint that I'd immediately abandon with the necessary slush fund to indulge in some extra power.
Anyway. With the Eunos tucked up in the garage and enjoying just the occasional outing - a roof down drive back from a party at midnight one frosty November evening a notable recent trip - I'm still of the opinion that the car is just how I want it at the moment.
Which, as anyone knows, is an inevitable precursor to pointless expenditure and fettling...

Mwahaha my shed (£850) 1990 V-Special, completely standard, including the very original n/s sill rust hole allows me to claim many purist points! (The 8 inch PH smiley doesn't detract points, does it?)
It's all a mattter of economics; I'm a poor student and can't afford upgrades

If I was in a position of adding power, ITB's would be the way I'd approach it.

Their head/cam/ECU package looks mighty temping though, brings the 1.8s up to around 160-170bhp for £1250+VAT. Great option for those wanting to stay NASP and retain the cars character. Adding ITBs on that package would probably go well...
Turbo, supercharge or itb ?
Afaik there is no off the shelf supercharger kits available in the uk at the moment, tr lane do brackets for the mp45 mini supercharger but heard stories about them not fitting great and need a bit of fettling. It's ok if you have the space to fit one and fettle but I don't have access to that.
Itb kits sound great and look the nuts but not much extra hp for a lot of cash, although driveablity is meant to be great.
Off the shelf Turbo kits are also thin on the ground in the uk, the US has two major players Flyinmiata and Begi but then you have to pay import etc. I'm probably going to bite the bullet spring time and import a no electronics turbo kit from Flyin miata but first off get a megasquirt fitted, Mx5nutz is the place for info on this.

Given the price of the cheap s2k these days I'd be tempted to go back there for an upgrade option. Strip all the a/c, electric roof and extra niceties from the honda and you'd have a 240bhp, lightweight, superbly gearboxed thrasher.
I'm drooling just thinking about it. BUT parts are much more expensive and I don't even want to think about insurance for a modified one....
