Getting parts used is a good way to go if you can find it. I'd always pick up new solenoids though to make sure they didn't get gunked up or anything from a previous owner. You don't want a crappy solenoid to stick open or closed...not that it happens often, but I like to avoid potential disaster

Iat switch> all

When it comes to nitrous I like to keep it as simple as possible.

I have yet to run into another nitrous car as fast as mine in mexico

The kit's I'm looking at where never used and are still in the packaging. The sellers just changed their minds for whatever reason.
turbotuner20v had a really nice kit I wanted to buy but the timing didn't work out.

Details on your setup?

I'm super **** so I'll have every safety precaution that I can. FPSS, wot switch, window switch, A/F switch.

When you say IAT switch, are you meaning a resistor or switch that tricks the ECU into thinking the IATs are super high so the motor pulls timing?

I was looking into something like that, or just fronting the money for the lingenfelter controller or something similiar.

416ci, 2 kits, I probably spray more than what others would lol.

yes that's what I've been using for years no issues here. The lingenfelter box is nice but I haven't had a need to replace what I have.

Do you mind PM'ing me more details on the IAT switch? Was it homemade or purchased? If not, no big deal, I just like to know what works and doesn't work for people. Thanks

I'm not one to go half-assed on anything so I'll likely go with a twin 10lb bottle setup and see how I like it. I can always add the NANO stuff later on if the shoe fits. I'm a symmetry freak so having 1 bottle off to the side will drive me absolutely bonkers. I honestly have a hard enough time dealing with just the driver's seat in when I race. It's some kind of OCD thing, but I crave and thrive on symmetry. I had both ears pierced and gauged, and my tattoos are symmetrical. It's a problem.

There are a few guys selling brand new plate kits at a fraction of the cost so I'll likely go that route after I figure out this whole clutch situation.
if you run the nano theoretically you wont need 2 nitrous bottles, you should be able to make 10 passes on 1 bottle

True, but I already have issues trying to keep the gas tank right at 1/4 full. I really don't want to have to worry about keeping the nitrous bottles full every week.

Although, I guess that is part of the equation. . .

Here are two differnt part numbers.
GM LS1/LS6 - PN 8625, GM LS2/LS7 - PN 86251
This is what we are running to take out timing while spraying nitrous. Also running a Nitrous Express NXD5000 - Nitrous Express Boost Reference Progressive Nitrous Controller. I am supercharged and spraying nitrous.
