Nozzle size help

[B833YKJ]

hello all,

I plan to run water injection 1S system on my series 1 escort rs turbo.

It's a 1600cvh with a GRS front mount intercooler. I'll be controlling the pump from a IECS monitor, in other words i'm only using the water injection as a safety feature and not part of the map.

Just wandering if anyone else uses water injection as a safety feature and what size nozzle they run?

Cheers
Dean
