Chriss=
i,

You may want to check out the Honda "SR20 power steering pulley" to
use as an oversized alternator pulley.  I used two of these for a
while until I switched to the Renesis water pump and crank pulleys.
They are 4" OD.  They have splines in the shaft bore that will need to
be removed, but other than that, they worked fine.  They are steel, so
they are bit heavier than their aluminum counterparts.  I bought mine
off ebay for < $20.
