The bearings are beefed up, and the OEM voltage regulator is modified for the higher current. Then a smaller pulley is put on.
The regulator is buried in the back half of the alternator case. You could probably have this done by a pro, but I wouldn't suggest doing it yourself. Getting the case aligned and torqued correctly to preven bearing/shaft damage is quite a trick. Any binding will prematurely kill your alt.
Take yours to a pro for rebuild with factory specs, or buy a performance unit.
