most aftermarket alternators that have a higher peak output will also have a higher idle output, usually.
give this place a whirl, I have one and I know several people that have used an alternator from here, and they work great, for my car it went from 105A peak to 180A peak and 85A idle and has worked wonders for my car. The civic one is and goes from 75amps peak to 135 peak and 60amps idle
