Assuming the alternator is dead on my car, what is the best replacement for my 1991 GTA? I don't want something that robs too many horses from my bird, but I dont want something that is going to give lousy output either.

My car is pretty much stock now, but I am looking at beefing up the horsepower and improving the handling. Will this make a difference in my selection of an alternator?

The only potential non-performace accessory I can see adding in the future that would draw a significant amount of amps would be a couple of subs. I dont think I need a beefed up alternator for that, do I?

Thanks again!
Bill

 

The stock 105 amp unit should be sufficient. Much more depends on the battery's amp/hour rating. If you add some more demand such as with an amp just get a higher capacity battery. The generator only maintains the battery, the battery itself really determines how much demand you can place on the system.
