hey guys i am a NX guy for ever and my friend has just got a zex kit and we don't know what the jet settings are we have a few pills that came with the unit along with a booster pump.
40
46

we are missing the jets for this space(car is not here at work with us)
78
82
we also are assuming that this system requires the use of two pills?
is it safe to guess that the settings for the pills are 40/46=75 hp,missing pills=100 hp,and the 78/82 pills are 125 or 150 hp(#%*&%#@) need to know A.S.A.P. thanks guys!

Is the kit a dry kit? If so, here is the info from my Zex #82018 nitrous tune-up sheet:

75 HP= Nitrous Jet 40
Fuel Jet 82

100HP= Nitrous Jet 46
Fuel Jet 78

125HP= Nitrous Jet 52
Fuel Jet 73

Hope this helps.

Those jetting recommendstions are correct! I am running 52/73 jetting right now, and it works great, even on the stock fuel pump(for now). I'm pulling five degrees of timing to be on the safe side, and it still rips! Oh yeah, the fuel jet(the higher-numbered on) goes in the brass fitting that one of the vacuum lines on the box connect to. I think you need a 7/16 wrench to loosen it and the jet is inside, so don't lose it.

 

thanks all
