Chrissi,
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.
