In the process of installing my supercharger (which runs of alternator), I decided to upgrade my OEM alternator to a DC Power 270 Amp Alternator. The OEM alternator is 110 amps. I paid $300 bucks for the DC 270 Amp Alternator. They usually go for $600+ according to the DC Power website.
The DC Power alternator was a direct fit to my 2004 6thgen Maxima. The installation was also straight-forward. I also did the “BIG 3” and upgraded all the wires to 1/0 gauge. This included the grounds and charge wire. I upgraded my battery to a Northstar AGM31 as well (but will save that for another post).
Please keep in mind the factory cables weren’t designed to handle the power of a higher-output alternator, and can restrict the flow of electricity (or cause cables to fry up). The “BIG 3” upgraded is highly recommended.
