[quote=spdrun]Problem is that if it has 280 HP and has to be warranted, it won’t be 2300 lb, since the brakes, drivetrain, and chassis will have to be porked up to handle the extra power/tq.[/quote]Brakes, yes, drivetrain, it depends, chassis, not necessarily (look at the Elise/Exige). Add in a turbo will probably add ~50lb and larger brakes and tires will add another 50lb. That is where I get 2300lb from, since the non-turbo weighs 2200lb. If you want to cut weight, you can always pay more and get a single piece forged wheels for example. Regardless, it’s very doable to get 2300 lb and still have to whole car beefed up to handle 280-300 HP, especially if the non turbo car is already 2200lb. You can also reduce some weight by getting titanium exhaust, light weight clutch and fly wheel, carbon fiber hood and trunk. You can go extreme and make it a hardtop with carbon fiber roof. I wouldn’t mind paying another $10k over the base Miata for some of those modifications.
If they can’t keep it down to 2300lb, I wouldn’t mind 2400lb if they make the engine stronger and turn up the boost to yield around 300-320HP. That would still be a very fun little car, not only in the curve but also in straight line.
