Any tips on removing a NOS system?

I bought a 96 LT4 Corvette that has a 175 wet shot NOS system mounted in it. Im going to remove it but am unfamiliar with NOS. Any tips I should know before I delve in?
 
Contact the manufacturer of the kit. Likely their instructions will be online. Just follow the instructions for installation; starting at the end and going backwards.
 
Just take it out. The hole where the nozzle was placed in the intake will need to be plugged, other than that it's just like removing anything else. Cut off and insulate wiring, etc.
 
I actually have the instructions for the kit. Its from NitrousWorks which is now out of business so I can work my ways backwards. The good news is that it used a spacer plate & no hole was drilled in the intake. I guess I was just concerned about disconnecting the tank. I wasnt sure if the system was under pressure or not.
 
Er, well, yeah, it's 'under pressure,' or it wouldn't work. But it's not going to cut your finger off when you try to disconnect the line. Just make sure the bottle is turned off. And use the purge if it has one. If not, maybe wear some gloves while unscrewing the line just to be safe- the initial burst of gas will be cold because of that whole 'science' thing.

I would be more concerned with how the fuel side is plumbed.
 
In addition to what's been mentioned:

With the car running, pull the fuse for the fuel pump. The engine will die, reducing the fuel pressure in the lines as it does. This will help you not spray fuel everywhere when disconnecting fuel hoses.

I would definitely wear gloves and hearing/eye protection.

It's a nitrous system, NOS is a brand......

A brand that happened to call themselves 'nitrous oxide systems' and thusly became rather synonymous with...nitrous oxide systems.

OW I HURT MY FINGER!

Does anyone have any...dual self-adhesive winged flexible wound-bandaging pads?

Oh, you mean...a bandaid?
 
It's called a bandage, or adhesive bandage. Now go troll someone else.

Never used nitrous personally, I assume wet kit has additional fuel added entirely by the stand alone nitrous controller and it could all be removed without any modifications to what is still a stock ECU.

Yes, a wet kit supplies additional fuel with the nitrous so the stock ECU doesn't need to manage it.

Dry kits rely on the stock ECU and fuel system to compensate for the addition of nitrous.

Both have their drawbacks.
 
Just make sure you run the tank out of pressure before you disconnect it. I suggest doing it on a private road or a track because you may just exceed the legal limits doing it publicly. 😀
 
Ran into a bit of a problem with the MSD Digital 6 Plus box hooked up to it. I removed the nitrous system and the MSD box. As it turns out, if I remove the MSD box, my Vette is very hard to start. It turns over for quite a bit of time before it will fire. If I hook the box back up it starts as soon as I turn the key. The box isnt hooked up to much. There is a heavy black wire that goes to the negative terminal of the battery and a heavy red wire to the positive terminal of the battery. Then there is a small harness coming from the box. The plug that goes to the coil of the car plugs into one end of the harness and then the other plug on the harness plugs into the coil. Lastly, there is a small red wire that plus into the power switch for the nitrous system. I know nothing of these MSD systems but Id like to remove it from my Vette if possible. Can anybody guide me on what is going on once the MSD box is removed?
