I also have a few water injection questions. (I would like to use water injection
in a non-efi application.)

What type (brand, cost?) of injectors are available?  Where might I buy one?
Do you have to use distilled or filtered water, or will tap water do the trick
(evil mineral deposits)?
Is the water atomized, or just squirted into the combustion chamber in big, ugly
drops?

Lastly, (shot in the dark) what kind of specs are typical for such an injector?
Firing frequency?  Is the water expected to be pre-pressurized to 75 PSI, of a
given temperature, or what?

Any help would be great!
