I want a dual alt pulley that is not under/over driven ..same size as stock.. who sells them?

 

Send a PM to Japan2LA, he's probably your best bet.

 

I have it but you would also have to upgrade to the 100amp FD3S alternator

 

^ I can vouch for these. 14.1 to 14.4 volts at all times using Japan2LA's pulley on my FD alternator. The only other one I could find that was the correct size was Higgi's pulley (silver w/ rotor on the front). Some of these are still floating around the rotary community, but I don't think he's making them anymore.

 

^I have a knightsport pulley on my stock t2 alt right now? Which is dead btw. would that dual belt pulley work on an fd Alt?
