Mazda Eunos Roadster: PH Fleet

Haters of open top Mazdas look away now, there's some more MX-5 love coming your way



So having driven and rather enjoyed BBR's 268hp Mk3 MX-5 and re-read our previous report on the updated 221hp conversion by the same for 1.6 Mk1/NA models like mine you can probably predict what I've been thinking about of late.

Buzz from Goodwood track day still lingers

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...

It's certainly a dilema Dan. Now I've moved to the Midlands from Exeter, I have a lot more circuits near to me and the idea of finally getting on a track day is appealing. Stripping the car out and tracking it is very tempting and adding more power to that formula could make it very good fun. Just got to stop the wife nagging me to sell it first.

That was a cracking day, a really great mix of 5s.

I'm going down the supercharger route with mine over the next 12-24 months.

M45 charger is a lot cheaper and you don't end up with a manifold the will crack after 5mins of hard use.
That and a megasquirt = 180bhp for starters. M

The S2000 is a bit of a different animal to an MX5 though. Having only owned a '5 I'm only speculating but I would think the MX5 is more smiles per miles with or without the extra power from forced induction

I'm always keeping the ITB'd Mk1 and I think overall it's better on track than forced induction. However I am supercharging my Mk2 smile

I dont disagree that a MX5 Mk1 is in standard form at current prices are alot of fun. Ive previously owned 3 MR2 MK1 for the same reason. I tried a supercharged version and realized that when you start throwing more money than it cost to buy at a car to make up for areas in which you feel it is lacking. Its not more upgrades you are after but a different type of car! Every car no matter how much you love it has a time and a place.

C.R.A.P Engineering V6 conversion if it were my money...

A shorter, lighter engine, 230bhp/190lbft and a lovely ITB'd V6 soundtrack.

What's not to love?

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

BLiNK Motorsport claim they don't actually offer any significant increases on a standard engine, not worth the cost any way.

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...

I've been debating this for months now.

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.

the S2k is a totally different beast and while does provide a lot of smile/mile, I found the one I owned very briefly to take so much effort to get it to sing that it detracted from the love for it ... it was very shortlived though and was stolen within 10days of purchase and never seen again.

I currently have a lightly modified mk1 track car and previously had a MY02 s2000.
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....

there's a guy on nutz making what appear to be very good manifolds and downpipes for a variety of turbo fittings, and for the 1.6 and 1.8 engine. he includes the water and oil lines. you can probably get the hardware for a (non-intercooled) turbo set up for £500
