There are actually three pulleys involved with the SC.

I replaced my SC14 CLUTCH/Pulley with an OEM SC12 clutch pulley from a Toyota dealer. Cost = $522. This pulley has an electromagnetically acutated clutch.

There is an idler pulley between the main pulley and the SC clutch pulley. Toyota will sell you these for a mere $174. If you do a pulley upgrade that is large enough, you will need to get a smaller idler pulley for the larger main pulley to fit.

Larger main pulleys have been manufactured by at least a half dozen companies. Some of their products had problems with the key/keyway on the inside of the pulley. They stripped out. The larger pulleys spin the SC faster and shorten SC life, but do it anyway.

TomsMr2's viewpoint of modding a 4agze to make the car more competitive and fun to drive is a valid one. Mod it, drive it, kick ass, have fun to the max! Adding 4 or more pounds of boost pressure will add more accelleration than doing a half dozen mods to a N.A. engine.
