    A while back I got a 3g upgrade kit from paperformance and their alternator pulley measured 2.5 inch across......My pulley that was on my stock 93 alternator measured 2 inches across. I know I can get a better charge with this smaller diameter pulley...just wondering if I can transfer it over directly to the 95 style alternator.

    The charge was the same when I did the swap according to my guages and I bet if I swap it out for the smaller one it will fit.

    Thanks in Advance :nice:

    it would probably fit, but you're probably better off calling paperformance before you do it and make sure it won't spin the alt too fast. the 2.5" pulley is on there for a reason, but you need to find out which size crank pulley it was designed to work with

    The shaft size is the same for both alternators.
