Will the Zerosports pulley for GC8 fit on a GD 2002RS?

Is it the medium size pulley theat I should change to get performance?

Here is a picture:

Is the medium size pulley the one with hallow circles right? And is this the so called "crank pulley"?

Thanks!~

You should just go in on the group buy.
I would if i had the money :(

Someone correct me if I am wrong, but I believe the medium pulley is the power steering pump. Big one = crank pulley , small one = atlernator pulley. I saw a med size pulley on ebay yesterday (zs & cheap) and it is listed as medium only and the description says to "check if it will work for eack application" The reason being that some of the pulley's are pressed in ( info from 4wf's thread on his custom made ones) and can't easily be removed. I suspect someone got a set of 3 for their sti and could only use two of them.

I think the crank pulley is most important followed by the ps then alt.

impluse777, thanks for your response. I was deciding if I should bid on that ebay auction, I guess I wont bid on it now. :)
