NX Wet Kit and GenX2 Upgrade Kit
 

NX Wet Kit $325

Kit number 20921-10 (Dodge EFI w/10-lb bottle, single nozzle), though I don't know why you couldn't use it on anything. Kit includes everything that came with it originally, and I even replaced what was broken or missing with new parts in packages. Includes an extra 3-ft fuel line. I've had the kit for awhile, but I ran fewer than 10 bottles through it. Comes with jets from 35-150 hp.

GenX2 EFI Upgrade Kit $200

Includes automatic bottle heater with pressure regulator, 35PSI fuel pressure safety switch, liquid filled N2O pressure gauge, NHRA approved blow down tube, and purge valve.

Everything's cleaned up, organized, and ready to go. Please PM me or email at thom1301(at)tc.umn.edu.
