If you want a good alternator (not a puny one)...this one ebay seller is brewing up an upgraded model. Trucks got 50amps... starions got 75... he makes this hybrid one listed for the station putting out 100amps. Its 100$ shipped with a one year warranty. Its on my shopping list since mines about to die...

88 Montero, StarQuest turbo, Kormex 5speed +tuff-pan w/phoenix f. stage2 clutch, 4in lift+33' tires, 4.875 lsd, short-throw shifter, Aisin hubs, SR big brakes, gen2 uca's, elantra alt, and so much more... 16g turbo w/hardpipes + 4.90 locking disk-brake axle soon (maybe lsd or aussie front??)
