I had good experience with Perrin Performance PWI-1. This is a very sophisticated system, but uses injectors duty cycle to adjust the flow, so only good for EFI set up. It has nice failsafe futures based on the water flow. It uses same components as Aquamist, but at much better price. I don't see it on their site anymore - maybe its discontiniued.
The idea of spraying water into your turbo compressor is not a good one. You will have erosion problems on your compressor wheel. Then there is the issue of uneven flow of our manifolds, especially the CIS one. I think the multi-port is the way to go.
If you run an intercooler, you should spray water after it, as IC works on temperature delta. If you pre-cool air going into the IC with water, your IC efficiency goes down. SO if you want to go with single point , the jet should be placed after the IC, before, or after the throttle body.
