about water injection on a toyota!!!!yeah toyota

[bravenight]

k new to this site so hey
any hows my question to all is
I have a toyota 2L,i have put on a turbo from a mazda 626,its max boost is 13 psi.i am not running a intecooler at the moment,but its on the works,so this being said yes problems with egt ,rising to fast,ive lowerd the fuel pump fuel feed,to were its not worth having a turbo,the size of exhaust running is 2.25
now from what ive read about water injection on a diesel.
does any one think this is possible to do to this motor,seeing it is an old school diesel.not controled by electronics and so forth.
im not sure what the fuel milage is at the moment.but after i have put the turbo set up ,power did increase like crazy till i had to turn down the pump to control the egt.
im told a intercooler will help with this big time and i can once again increase my fuel and experiance the power of a turbo.

so as well im wondering about the water injection and how to go abouts doing this.what is all needed to know and how to go abouts doing all this?
thanks
