Your volts should NOT be doing that with an 85 amp alt, it's either a bad ground somewere as Rollon suggested, or most likely, your alterantors had it. Do you still have the fan cover on underneath the car? Alot of the time these break off when parking close to gutters etc. Without one, the alternator is exposed to road grime and will kill the alternator quicker. You can take the alternator to an auto elecs to get it tested for like $5 or $10. They'll tell you the state the alternators in and whether it needs a reco (a reco will set you back around 130-150 dollars)....
As for alternator upgrades, that's a whole new ballgame. I had a thread here a while ago that pretty much outlines the bullsh!t involved when upgrading the alternator on EA-ED's...
