I got a used system complete except jets. these kits came with 75,125,150, and 200 shot jetting. I need to know the jet sizes. Anyone have this kit?

Check TNW's web site or just use a nitrous jet calculator. Usually factory jetting is pretty rich to keep everything on the safe side and there's power to be had by slightly leaning the fuel jet out. I use the calculator for all of my jetting after talking to NOS techs and hearing about the same recommendations my calc was giving me across the board. Just make sure your fuel supply can keep up with the volume and the pressure and you'll be a happy camper for a long time using your kit.
