We're not going to say the Miata is underpowered. But we will say that it's such a nice-driving package that it simply begs for additional horsepower. One simple way to add 10-15 additional ponies is to add some Mazda underdrive pulleys. New Mazda pulleys don't make additional engine power; rather, they shift power from your accessories to your rear (or front) wheels. See, those accessories, like air conditioning and power steering, soak up a lot of your power when you have stock Mazda pulleys on them. By driving them more slowly with Mazda performance pulleys, you retain their capabilities but make them easier to run. So why didn't Mazda do this in the first place? Well, engineers have to account for every variable when designing stock Mazda pulleys. That includes Grandma Jones who never gets her 626 over 2,000 RPM. So the factory Mazda pulleys turn the accessories pretty quickly even just above idle to compensate for less aggressive drivers. Since you drive your car with gusto, you'll still get more than adequate accessory performance with underdrive Mazda pulleys. Just keep Grandma out of the driver's seat.
