water injection installation questions

[Thealastair34]

hi all,

im wanting to run water injection in my engine to help lower inlet temps, as you can see i am very limited to space and have the largest intercooler i could sort of fit within the bodywork.

i am new to this and have won a snow performace stage 2 kit from eBay that i am waiting to arrive.

it has no nozzles with it so i need to get some but need to know how you spec them for the engine?

also im not sure if its a single or dual nozzle kit are there benifits to running say two nozzles?

any help would be great as like i say ive not dabbled with water injection before

thanks alastair
