does anyone know where I can find a h.o. alt. 91 gxe vg thank you in advance

 

Where are you? Try Ohio Generator, Mean Green, Mechanical Man, etc. But I seriously doubt you need a really high output alternator unless you are using your car for SPL competition and don't own a good power supply to recharge the batteries. Problem with HO alt is that they only provide higher output at highway or faster engine speeds. At idle they provide less current than a stock alternator, a matter of basic physics. Aside from that the higher output the alternator the more difficult it is to mask the alternator whine that is caused in the AC / DC rectification or whatever it's called.
