setting up a direct port water injection system.
 

i'll be injecting the water directly into each of the runners of my turbo 4cyl, and the question of nozzle placement is bugging me. does it matter where in the runner (closer to the plenum / closer to the port) i place the nozzle?

thanks!

wouldn't think so mate, this is not nitrous that you want to keep in liquid form until the very last moment.
With 4 nozzles though, you run the risk of dumping too much water, let aside that the water pump may not supply enough pressure for all of them.
I think that a single (or dual) nozzle setup would normally be more than enough for a 4cylinder, even if it runs silly boost.
