Pulleys?

Hello again,
For us uneducated folk, is a 94-95 SC pulley the same as a 89 and up pulley in outside diameter? Thanks, Rob

No, the '94-'95 pulleys are slightly larger than an '89-'93 pulley. The difference is about 3% or so.
Thanks, this is what I thought also. Probably no advantage to installing a one on a 90 is there?
 
Absolutely no advantage, you are going in the opposite direction and reducing (underdriving) your boost. I do the reverse and use the stock '93 pulley on my '94, to give it around 3-5% overdrive and 1-2lbs of extra boost.
