Your best bet is to cut the step out of your heads to increase the
turbulence so it will run on 94 octane fuel. NA engines need pretty
sophisticated water injection systems. Stock 110hp heads are probably the
most prone to detonation.
Turbos are also prone to detonation, but a water tank, pressurized by the
turbo with the right size nozzles is actually a much simpler system.
There is a lot of information on modifying heads either in the archives or
ask how to do it on the VVs and you will get a lot of information.

Hi all...I have a write-up for my water injection system, but I need some
more time, as I am planning on upgrading the system with a temperature
switch that will turn the system on automatically when the engine warms up.
Currently, I watch the oil temp gauge, and when it hits around 120 degrees,
I flip the switch. That takes around 10 minutes of driving when the outside
temperature is around 50-60 degress Fahrenheit.
With the WI system off, I notice that after that point, the engine will
begin to ping under hard acceleration, but with the WI system on, it NEVER
pings no matter how hard you press on the go-pedal.
It is critical in my opinion, that the WI system be capable of fully
automatic operation. In the event someone else drives the car, there is no
guarantee that they will energize the system after the motor warms up, with
the obvious danger.
