Until the Mazdaspeed version of the MX-5 makes its debut, those of us looking for forced-induction power from Mazda's NC Miata must turn to the aftermarket. Of all the tuning firms looking to turbo- or supercharge the new MX-5, Cosworth has both the reputation and technological prowess to pull it off sans drama.

According to Eric Hsu, founder of XS Engineering and current Cosworth engineer, despite some setbacks, Cosworth will be releasing its bolt-on supercharger soon. The setup produces approximately 210 hp at the wheels, looks OEM clean and is designed to be legal in all 50 states. But Cosworth isn't stopping there. Hsu says that a Stage 2 version is planned that ups the boost, adds a set of headers and includes some hotter cams. We can't wait to check it out, particularly with the "1G" suspension package offered by Mazdaspeed.

      Unless im wrong, wasnt there already a MPS Miata like last year or the year before....an 06 (first year of NC)???
      • 6 Years Ago
      This kit is just what I've been looking for. A blower gives more low end grunt than a turbo, without the plumbing problems. Yeeeeeehaw!

      Assuming we're talking about the 2.0litre engine here i *think* its the same Ford Duratec engine that Caterham has fitted in their R400 (210bp NA) and the new R500 (250bhp NA as seen in the Autocar video the other day). So why *only* 210bhp from a supercharged Miata? Is the Mazda unit different from the Duratec in some way? Or is it just that the rest of the car can't take the heat/torque/stress? Often thought that an NC with 250+ bhp would be sweet.....
        • 6 Years Ago
        Don't forget it's 210+ AT the REAR WHEELS. Thus it probably makes around 240 in the engine.
        • 6 Years Ago
        Justin: That was my initial questions as well. Eric says in his post that "it feels like the torque curve is a flat line from 2800 - 6500rpm." Unfortunately, no numbers or a dyno graph were supplied.
        • 6 Years Ago
        Darth, it I believe the article says 210 whp, not bhp. Which puts it up in the 250 bhp at least.

        Personally, I want to see a torque curve rather than peak figures.
        • 6 Years Ago
        Well, it is also 50 state legal...Dont forget that

      I'll take the Solstice any day over the Miata. It does everything the Miata does plus more. It's also a much better looking car.
        • 6 Years Ago
        Yeah, about 400 pounds more, right?

        I think the Solstice is a good-looking car too, but the Miata has the total package. Light weight, usable trunk, stupid-easy roof, huge aftermarket, track credentials...

        Yep. I like my car. : )

      In 1997 210bhp sounds awsome in 2008 210bhp is what my daily driver accord has and more.

      =/

        @Mez Jr,

        The NC can take a good deal more tire than the NAs and NBs. I'm planning on moving to 285/30R18 on the rears for autocrossing. This does require rolled fenders, but doesn't require modifying them beyond that (fitting the same on the front requires more effort). I'm currently running 235/40R17 for street tires, and it could easily take more if I wasn't stubbornly sticking to the OEM 17x7 wheels, there.

        210rwhp in an NC would be quite a blast, especially with the flat torque curve one would expect from a supercharger. Still, I have no desire for forced induction on my NC anytime soon. It's doing great as a CSP car.

        Does not…

        2008 ACCORD - 3609 lbs / 268 hp = 1hp/13.5lbs
        2008 MIATA - 2444 lbs / ~210hp (Cosworth) = 1hp/11.6lbs

        • 6 Years Ago
        @I3ziko:
        "Does not…

        2008 ACCORD - 3609 lbs / 268 hp = 1hp/13.5lbs
        2008 MIATA - 2444 lbs / ~210hp (Cosworth) = 1hp/11.6lbs"

        An even better calculation would be:
        2008 Accord: 3609 lbs / 228 hp(at the wheels w/ 15% loss) = 15.8 lbs/hp
        2008 Miata: 2444 / ~210 hp (Cosworth, at the wheels) = 11.6 lbs/hp

        That being said, the Accord will still probably out accelerate it in a straight line. Just wait until the twisties...
        • 6 Years Ago
        210 rwhp in a MX-5 "should" run faster than a 350z, G37, Solstice GXP, Mustang GT, GTO or cars in that range, puts it about 12lbs/whp.

        You really don't want too much power in a MX-5, they're not tired for it, and I don't know about the NC, but the NB/NA can't take huge tires, so anything over 270rwhp or so and its just spinning tires.
        • 6 Years Ago
        Your Accord doesn't weigh 2600 lbs.
        • 6 Years Ago
        Hey bench seat Internet racing, it's the numbers that make a car fast!
      • 6 Years Ago
      I think it will be cheaper to get a kit from FM or BEGI and install it yourself. Just showing options. Both companies are working on them if they dont have kits for the NC already. I have an FMII on my NB and OMG it's fast with around 265 at the rear wheels. Mine's a turbo and not SC like this article talks about, but I'd look at turbos too. You can pass emissions tests with the offers from FM and BEGI.

      210hp in a Miata with upgraded suspension...Now that is the sort of fun car I want. Not a gtr, not a zr1, not a 911 turbo. I want something fun; not terrifying and expensive.
