There is a section dedicated to this...https://www.rx7club.com/auxiliary-injection-173/
I, personally, have an AEM injection kit and use a 50/50 mix of water and methanol.

Moving to get the right help.

coolingmist

you can ask 10 people this question and get 10 answers. What you need to do is define the scope of what you need a water/alcohol injection system to do.

Look into the following:

1) how do you want it to activate? 1 input, 2 inputs, 3 inputs? In othewords, do you want a 1D Map or 3D Map.

2) What method of injection? Do you want an on/off kit, progressive kit, or Valve based kit

3) Do you want/need a failsafe?

I would invite you to visit us at www.coolingmist.com.

You can call us if you need help as well.

there are two distinct AI architectures currently available.

they are very different and both work well depending on what you plan to do w your car.

the traditional AI system delivers AI injectant based on pump speed. generally, the pump speed is influenced by a solid state controller and references off boost.

i say "influenced" not controlled.

that is the primary problem w the "pump speed" setup. if you are on and off the gas in a corner on a road racing track your boost will fluctuate instantly and greatly. the pump, due to it's mass and various mechanical impediments cannot turn on a dime, let alone a millisecond. so you get uneven delivery. if you drag race, these systems work fine. road racing not so fine.

the second architecture is constant pump speed w a fuel injector. this is the modern delivery system and works similar to your car's OEM gasoline/fuel system. generally the pump provides a constant pressure to a solenoid (fuel injector). the fuel injector is controlled by an AI computer and opens and closes in the millisecond range thus delivering exact amounts of injectant. delivery is controlled, yes, controlled by your settings on an X-Y grid using generally rpm and boost.

Aquamist, Coolingmist and FJO currently offer such systems.
