I think that 574 of those pulley messages were from me.  ;-)  I ended up using the Prelude H22A power steering pump pulley.  The Prelude p/s pulley matched the shaft diameter of my 55 amp Geo alternators and the overall diameter is about the 4.0".   The Geo's shaft diameter is smaller than the Mazda's. Also, the Prelude pulleys are of the multi-vee type.  I thought I spotted a Prelude p/s pulley on Tracy's Renesis engine.  You may want to visit your local auto-electric shop and see what they have.

Thanks Mark.  I'd like to find a dual pulley, as opposed to multi-vee (serpentine) if possible, since that's what my other pulleys are set up for.   The local auto electric shop would certainly be the place to look, now that you mention it.  You don't happen to recall the diameter of the shaft do you? 
 
I'm also looking at a couple Meziere EWP's, and have an email in to them about flow restrictions and such.  At this point, I either want a second belt (cheapest, easiest) or another EWP in series with the mechanical pump.  
 
Thanks,
Rusty
