Default water injection question

Just started to set up my water injection and was wondering where people are mounting their nozzle at. I have a STi with factory I/C. I am thinking of mounting it in the Y-Pipe of the I/C befor it splits.
Can U drill and tap the Y-pipe? I thinks its cast, ashould be able to?
Where are other people mounting it?

I see a lot of setups with the jet pointing down at the IC to throttle body hose location.

I don't think that would be a good set up.
I think the idea is to get the water/meth atomised(sp) into the intake stream.
Having it at the TB would make it almost strait liquid.
Pistons don't like liquid!

If you take the intercooler off and look inside the outlet, there is nice little flat spot on the bottom just beyond the outlet. It is right in front of the core. That is where I like to mount it. really ease to drill and hides well. It's kinda stealthy mounted right there.

Mine appears to atomize just fine in the spot right above the TMIC outlet... gains are from nozzle changout from 175ml to 375ml, nothing else. I didn't change nozzle position either. It is the same as before, right above the throttle body in the intercooler

I have it mounted at teh outlet of teh intercooler. I use a MRT TMIC, not a OEM, but the concept is the same. The runners on our cars are long enough, that I think we get much better atomization than that of a inline motor with a 1 into 4 intake manifold. On an inline car I would mount it closer to the turbo outlet.

I did mine like this, courtesy of Riftswrx:

"At this point all that's left is finding out where you want to mount your nozzle. >I< drilled a small hose in the silicone intercooler hose going to my throttle body, then using two washers I pushed the nozzle through the hole, and then screwed on one of the brass hose fittings. The washers pressing the silicone, effectively making a gasket. At that point I simply connected a length of hose from the solenoid to the brass fitting."

Aquamist actually makes an intercooler to throttle body hose with two bosses for the injection nozzles.
