I have a complete NOS nitrious wet setup for LS1 cars. Not sure if can be used on LT1 but don't see why not. The kit is complete, you will need nothing.

10 LBS blue anodized bottle(nicer bottle)...Bottle is FULL!!!
NOS BLUE LED purge
All the lines, cyliniodes, fittings, jets
Dyno tune bottle heater, pressure switch.
Dyno tune window switch, with 2 different gear lock out

I am sure I am missing something. The kit has been used before, but never by me. The bottle Heater, window switch and the blue LED purge are brand new.

I am wanting $500.00 for the complete setup, plus shipping. Will add photos later.
