You will just need one nozzle with your set up, A DO7 should do the trick for you at that power level. I would get the low boost kit 2-10psi
pressure switch.
If you look at our kits part for part the others cannot touch it and we don't force a tank on you. Even if you buy one it's still cheaper than all the other base kits and you get more and no cheap plastic
pressure switch.
