Upgrade alt wiring stuff

>Anyone upgraded the wire size to the alternator before?

I did this on one of my B13's. I actually left the stock wiring in
place, and added an extra 8 gauge wire alongside it, with a fuse at each
end (because each end of the wire has the potential to be "hot".)
Anyway, I had car stereo amps that would draw close to 150 amps at full
load, and a large deep cycle battery. I couldn't tell bit of difference
in the voltages, drops, etc before or after doing it. As a result I
didn't bother in any of my other Nissans after this.

I found more difference in the alternator by playing with pulley sizes
and overdriving the factory alternator (smaller pulley).

There is a crazy DSM guy I know who competes in audio competitions with
his car. He rewired the entire power distribution portion of the wiring
in his car with the good stuff. Took him months to remove, disassemble,
reassemble, and reinstall the upgraded wiring harnesses. He's a nut.
