The math is pretty simple, it takes power to spin a pulley. The heavier the pulley is, the more power it will take to spin it. Your motor is limited in how much power it can make. By swapping to a lighter pulley your motor will spend less power spinning pulleys, and more power spinning the wheels. Since it's easier to get the pulley spinning in the first place, you'll also see an improvement in throttle response. Not to mention that you'll be shedding nearly 3.5 lbs.

Fitment Notes

These pulleys are designed for ND Miatas with manual transmissions only, and will NOT fit ND Miatas with auto transmissions.

If you have an alternator decoupler, the alternator pulley will NOT fit. Not sure? Send an email to and we'll be happy to help!

The Complete Package

To maximize results, we've built this kit to replace three of the pulleys on the accessory drive system of ND Miatas with manual transmissions. The pulleys replaced are the crank, water pump, and alternator pulley. All three CravenSpeed pulleys match the stock pulley diameters, so the stock belt sizes are maintained, and accessory output is unchanged. They are precision machined from aluminum for perfect balance, and anodized black, right here in the USA. Installation of these pulleys is fairly straight-forward with no specialized tools required. We'd expect it to take 2-3 hours.
