The problem is 99.7% of water injection kits either supply a fixed rate of water, or ramp things up based on boost pressure with no regard for how much water is actually needed. You need to keep water:fuel ratio precise (since we tune fuel to match the amount of air entering the engine, this keeps water/power ratio predictable) and then tweak individual injector fuel trims to get everything to match up.
Or that's the idea, anyway.

make a throttle body space with a venturi, play around with jetting to get it right, and have a small pump to olny supply water when you are under boost, would help to have a vacum manifold so you can pressurise the holding tank and the "fuel bowl" basical a simble carb but alot bigger than normal so it dosent restric flow to much

bigger picture? you would need a second fuel pump and fuel press reg to fed the injector, boost pressure i dont think would be goo enough, also i dont how you would get the injector to open anc close, i dont how they work.... :1

Injector internals are stainless, they will not rust.
The problem is spray pattern... or complete lack thereof. Fuel injectors are designed to atomize not-water. Water shoots out in a squirtgun like straight line. You need to lower surface tension to get water to atomize through a fuel injector....
