newb questions about nozzle placement

[percevil]

Hey guys,

I'm new to the forum as well a water injection.

I own a 08 Mazdaspeed 3 with all the bolt ons ie fmic,full intake exhaust,Cobb Ap with custom tune as well as a gt2871r upgrade.
I'm looking into HFS 4 kit and had a couple of questions.

My engine being DI has 4 1700cc injectors. With the calculations provided on the Howerton website I should be using x3 1mm nozzles. Is that correct?

So if I'm using all three nozzles, where would you recommend these nozzles be placed for maximum effect?

All in the same area spaced out? In three strategic places?

Thanks Percy
