Cole,
Glad to hear that others are pursuing WMI! Please keep the info/pics flowing.
I'll be going with an Aquamist HFS-3 on my turbo carrera. Aquamist systems were priced up in the stratosphere up until this year. I'm guessing that you're into your Snow Performance System for $500+? The HFS-3 runs for around $700:

The nice thing about the HFS-3 is that it comes with a single gauge that indicates flow rate and fluid level. Very slick setup. We'll be installing one injector on each side of the manifold.
Best of luck!
