well i asked them for a 280amp alt they said because of the space the biggest they can do is 250 unless im willing to do custom work to make a bigger alt fit so i dont know what the other options are. i think 02zetec is getting one for 220amp. they are direct bolt on h/o alt no mod needed just upgraded wires. could go to your local parts store to and buy and interstate deepcycle for under the hood about $90 so that while at stop lights you dont have as much voltage drop. still under the $500+ for 2 batteries then.
