Default NX Jet sizes?

I am looking for the Jet sizes for the LS1 NX wet kit. I need the nitrous and fuel jet combo for a 100 and 150 shot.

What are the ones for 175 if I get brave?? Im guessing a 67/35-37?


I have 57/31 for 125 shot

62/33 for 150 but I have found 62/35 works best for me

Good Luck

Actually no they are for a efi application,Like I said prior I run my system a little diffrent.I use the fuel rail into a holley carb regulator,then from there I run a fuel pressure gauge on the regulator,then I can regulate fuel pressure going to the nozzle almost like a carb setup.No matter what you have to regulate fuel pressure to the fuel side of a nozzle or plate.Nx recommends you flow the system at 5psi or 10psi,I found out that you need a bigger pump(255lph)to run 10psi.
This setup has worked very well for me and I have set it up on all of my friends efi mustangs and my buddie just ran his wed nite it ran 14.30@99mph on motor and 12.40@116mph on a 150hp letting out at the 990'.So to each his own but it works well for me.Hope that sheds some light,If you need pics I will be more than happy to email a pic or 2 if anybody else wants to try it!

Are those definitely the correct sizes for the 125 shot? I really would like to know because I have never seen them before.

Thanks!
