Took a while but I found my Neon liked shifting by 2.5K RPM. Sounds like this 1.0L half-ling isn't far from the same. So I'll give that a try!
Yeah sounds simple enough to make and install. Just wasn't sure if component choices have changed or been redefined over the years. I'll check out Amazon... 2 day shipping VS 2+ week shipping from some of those ebay auctions...
I have plenty of 12v power supplies laying around I can use (wall warts, computer supplies, etc.) doesn't seem like that fan is gonna need many amps.
Thanks for all the help.
Edit: OK ebay ones it is... hard to find otherwise, unless one wants to throw out some serious bucks! ah well...
