Default Water Injection Install questions

Does anyone have write ups on installing water injection in the STi?

I'm curious as to where people have mounted the nozzle, from what I have seen directly into the intercooler.

Pictures would be great.

Install the kit under the wiper well (black plastic piece under the wiper arms). There is a surprising amount of space in there to mount your pump, valves, and accumulator. Run the water sprayer hose to the high pressure pump and finish off with the electronics. This install can actually be fairly difficult depending on wiring.

turboICE or chargedperformance (Ed, same guy, two accounts) makes a kit that uses the water sprayer pump to prime the WI pump. Ed can help you out. He has all the circuits figured out and the pieces, he may want you to buy a kit,but he is very helpful.
