Mazda MX-5 25th Anniversary Edition | PH Fleet

Modifying an MX-5 usually means making it more fun - time for a shakedown at Curborough


One of my many Man Maths equations for cars I shortlist is power-to-weight ratio, and my spreadsheet is forever expanding with cars I’ve owned or want to buy. With 160hp and a kerbweight of 1,248kg, PL64 EPU is at the bottom of the list with 128hp/tonne. But this is not a car you can easily assess on paper, and I can't be alone in thinking that the pursuit of power - to the exclusion of most other concerns - is a fading preoccupation in a world now clogged with preposterous and mostly meaningless outputs. Far more fun to drive a slow car fast these days than the other way around. 

What I wasn’t prepared for, even in the light of this realisation, was for the plucky little Mazda to be the most fun I’ve ever had on track. I organised my first private sprint event at Curborough sprint course over the summer, and the MX-5 was hilarious, despite being one of the slowest cars on the day. Just like on the road, you can drive it flat out everywhere without fearing being thrown into a barrier at triple-digit speeds, and it wanted to go sideways at every corner.

The modifications covered in my last update really shone through here, with the car being beautifully balanced and (almost) always pointing where you wanted it to go. When I owned my Series 2 Lotus Elise 111S I could never drive it with so much confidence – it caught me out on a handful of occasions with the back end snapping out, and it never felt that controllable. In hindsight I wish I’d had some driver tuition in it to make the most of it and learn the balance of a mid-engine sports car. Next time.

The MX-5 on the other hand, being front-engined and rear-drive with a limited-slip differential, felt endlessly controllable. With the traction off, I could turn in late, floor it and just let the car slide. The only thing wider than my grin was the tyre marks I assumed I must be leaving at every corner. 

In reality, it was probably the smallest of skids from the outside, but, as we all know, there is nothing guaranteed to make you feel more like a hero behind the wheel than applying opposite lock to it. Predictably, the track highlighted its power deficit in a straight line – I’m a firm believer that the best balance of fun and outright speed is to be had around the 200hp/tonne mark. So that’s nothing a supercharger couldn’t sort. 

Suffice it to say then, that my 25th Anniversary Edition ownership has been everything I’ve dreamt of over the past decade. I’d planned to SORN it over winter but given it has been relatively mild so far with no grit going down on my local roads, I’m still enjoying the occasional blast sporting a beanie on a rare crisp day. A year is a long time for me to own a car so as I approach that anniversary, and the appeal of switching to an ND2 is strong - but so is upgrading my NC to a BBR185 package. Let’s see what the new year brings, eh...

That GTB is heroically dirty!

Is it still running the twins? That'd be hilarious on that circuit.

I agree with your sentiment, driving slower cars quickly is fun, my na eunos is far from quick but is great fun on the road, my daily 500 S 1.2 is obviously slow, but again huge fun to drive. I always feel it's more satisfying to be able to use the available performance than to feel restricted and not appreciate what a car can do unless on a track.
Your nc looks great on track in those shots, winter driving with the roof down is great, especially with NC onwards as the roofs are quick and easy to put up, on mine I have to get out as I can't reach it from the driver's seat.

Couldn't agree more with your opening paragraphs Ben.

Also couldn't agree more with the figure of around 200 BHP per tonne. It really does seem to be the sweet spot. Anything more than 270 BHP per tonne unless massively specialized tends to be overwhelmed by the power in my view and becomes limited.

To my eyes at least, these look much nicer than the ND especially in that Mazda red.

If you want to get to 200hp/ton, forced induction is a good option. Rotrex works well….

100% !! I just can't over the rear of the ND, front and side angles are lovely but the rear is downright ugly and awkward. NC has aged much better.

Been looking at NC 3.75's with the folding top over the last few months, would make a great winter car. The problem is, I could spend as much on mods as the car itself and also worried it will be a bit boring compared to my much loved S2000 I regrettably sold (twice).

Buy one pre-modded where someone else has spent the money for you?

Although if its a BBR turbo, I'd avoid the BBR (koni) suspension as it's pretty bad on non-smooth roads, the Meister R coilovers on the other hand are well regarded.

Yeah but half the fun is planning, buying and seeing the incremental benefits of modifying a car.

I'm an ND2 (with BBR Super 220) owner and agree that this NC looks great and arguably better than an ND in any of the currently available colours.

Get it boosted and keep it for at least another year or two

It gets washed once a year, whether it needs it or not wink

Yes it's still running twin turbos, although is currently getting some TLC ready for another year of nav rallying. 13 years in and still loving it!

I can highly recommend a forced induction MX5. I had a supercharged NB and it was hilarious at curborough.



With some power in them and a few chassis tweaks they are so playful, they let you away with murder and don't really bite.

I've just bought a hearing-aid-brown ND2 in 1.5 guise and echo your comment about driving a slow car fast.
Takes me back to when I first started driving and had to redline it everywhere to make any meaningful progress in my 1.2 Clio. All the more fun for it!

As well as the usual Meister coilovers and raspy exhaust on the upcoming mods list, I've got a Cusco LSD going in, alongside a much shorter final drive.
The two latter items are fitted to a friend's car, and make the drive an absolute hoot. Less effort required to access those revs and crisp gearchanges and along with skinny tyres; rear-end grip levels even easier to breach!

Close your eyes and you could be at the dentist.

My NC BBR Super 200 is a joy both on and off track but I do hanker after a tad more torque. Ideally the 2.5 duratec on ITB’s and with the cams and manifold fitting the 2.5 and suspension already done you would think the man maths would work but it ain’t cheap. Seemingly the supercharger option wouldn’t work with the cams? Thoughts?

Beefy NA power is always a winner. The supercharger on mine was great but by god did it generate some heat, and the noise at 70mph on a motorway was insane laugh

When I next relapse and get another MX5 I’m really interested in the 2.5 swap.

Also thinking the same, I'd rather keep it naturally aspirated. Found this company, not sure if they're reputable or not, but the swap is £3200. Cost of the BBR 200 package.

https://performancelink.direct/engine-services/#En...

Duratec 2.5L 4 Cyl 190bhp+ £3215
A popular swap for customers looking to improve performance (especially for road applications) can choose to upgrade to the 2.5 litre Duratec Engine. This engine offers a significant jump in torque over the 2.0 making it excellent for quick overtaking and fast point to point driving. Each 2.5 is offered with an upgraded manifold (if not already owned) and is custom dyno mapped for reliability and performance. Camshafts to increase power further are available.

That's going to be a riot in the real world. Very short gear ratios in a small light NA car is a brilliant recipe for fun at sensible speeds. Happy days !

That’s very interesting, thanks for letting me know, hadn’t come across these guys before. Had only looked at BBR and DanST, good to know another option, will do some digging - anyone know of this outfit, be great to hear your opinion?
