These guys sell them. I bought a pulley and belt from them for my SC 2003 Cobra. You probably will not need a new mass air flow sensor unless you running some major boost.

Some cars can be rich from the start and a slightly smaller pulley with more boost won't hurt your engine. But all cars are different and respond different to mods so you would definitely need to put it on a dyno (before you get on it) to tell how safe your factory tune (air/fuel ratio) is with larger amounts of air being forced into the motor. They say on their site that you do not need a new tune but I wouldn't feel safe unless I got it checked. You don't want to lean it out and fry your motor.

Hope this helps a little.
