Have any of you changed your alternator in your Z? I looked at WranglerNW alt's as well as Ohio Gen and they're about the same price for 180 amps. Then I found an SGP Racing alternator that outputs 220 amps. I know 350zspl has the WranglerNW alt and he loves it, does anyone else have a HO alternator installed in their Z? I'm really interested in the SGP Racing alt as it has the highest output I could find.
