NX only makes wet kits. which kit doesnt really matter, 90% of people buy a basic n2o kit.
u need to start off with a 50 shot, u will really feel the new tq. after ur happy and know what ur doing, go to a 75 shot, then 100 and so on.
at best. Like I said I don't run an NX, so thanks for informing me that they don't offer a dry kit. 
This should get you close. The sizes should be stamped on the jets.
I'd start out with around 100hp for trials. The reason being that something could be wrong like a lack of fuel, and with a 50hp shot you may never realize it.
N2O / Fuel / Horsepower Gained.
34/18 40HP
37/22 50HP
39/24 60HP
41/26 70HP
43/28 80HP
46/30 100HP
52/33 125HP
61/38 150HP
