I'm new to the fourm, and repairing cars in general.. but if I can install an alternator on a 1989 mazda, then alternator on a 1989 bonne, is a piece of cake. I'm about to get a 89 bonne for free in a few days. The alternator is bad though, and I need a new one. I plan on putting a good stero system in later, and would rather put a larger alternator in now. I did a search for high preformance alternators and found a brand called stinger. I'm wondering if I should just goto the autozone and get a replacement or put a higher preformance one in so I can do future upgrades, and wehre could I find high preformance alternators.
