Using WI on RX7 Turbo 1991???

[SweetCars]

Hi everyone,

I'm new on this forum cause I really want to learn a lot about this technology. I have a Mazda RX7 Turbo 1991, and after some test of other persons it seams that water injection has a lot of benefit for the rotary engine and solves all his defaults...ALL!!

So I'm really interest to do this on my car. My car has a complete setup for about 12 psi and 280hp with the stock Turbo and ECU. It has the APEXI SAFC NEO with stock primary injectors (550cc) and 880cc secondary.

I would like to know first if its possible to install a WI kit on my car, even if I dont have a standalone?
And which kit would be the best for me....considering that maybe in the future I wont stay with my stock turbo and engine management and go for bigger turbo with standalone to get about 400whp....because I would like to keep the same kit and just tuning it not to buy another one for my bigger setup?

Thank you all for your help!
