I've found the NOS nozzles work ok if the jet size is above .025ish. Smaller than that, the spray turns into a small stream. If your using one nozzle, you'll probably need at least a .030". Probably one of the best nozzles are the Aquamist, but you'll have to use more than one to spray enough (they don't make them big enough).
By the way, I found I had some pressure loss when mounting the pump in the trunk (60psi Shurflo pump). It seemed like I couldn't get a decent spray. I am temporarily using an external fuel pump (95psi) up front until I get a higher pressure pump for the back (or switch to the higher pressure pump head).
