im not sure that 2 alternators would be cost effective.

here is my solution, on z31performance.com lots of people have tried many different alternators.

the most common being a maxima 90amp, quest/villager 110amp and the 350z wich is somewhere around 110 amps i think.

 

i personally did the quest alternator on my vg30, it was pretty much a bolt on affair and almost double the ammount of amperage.

 

also in my stock pathfinder i run 15"PPI sub with an 800watt pioneer amp, and its worked great for the last 2 years.

You cant run two independant alternators tied to the same system! you will fry both alternator regulators and probably all the electronics in the vehicle alnog with the wiring.

I would think that it MIGHT be possible to make it work somehow, but you'd need to be installing a bunch of isolating diodes etc. so you can insure that the alternators can't interact with each other etc. Probably not recommended unless you have a good handle on electronics!

Why not? Magregor did it on his wd21 and had no problems. So did another member near me.

 

Robb PM magregor or pathie4me, they both live in ottawa and have done dual alternator installs.
