Overkill really. A single nozzle will work just the same for a 50 shot and will save you $200. Direct port setups are usually used for 100+ shots.

I would not bother with a direct port set up at all.
If you are sticking to such a small shot, you can definitely get a cheaper kit than that. ALSO, Don't forget the safety equipment. (full throttle and window switches)
On the other hand....you have other fingers.

so it would work the same as a regular single nozzel without having damage on my engine,im getting this kit because i made a deal with a friend that wants to trade a new direct port NOS kit with a 50 -150 shot for one of my alienware laptops.
