I'm rebuilding my S5 turbo and I want to run water injection. I saw a video on YouTube where someone set up a pre-turbo water injector on an fd. It looks interesting. I don't know much about water injectors (aside from the fact that they use water to cool the air going into the intake a bit) but my builder recomends I look into them since I plan on running the tmic and stock turbo for a while. Can you guys recomend a good set up for the S5 13bt pre-turbo or other wise?

 

look 1 topic below

 

its probably my fd when i had the pre turbo on. pre turbo is over rated.
