Looking at getting the wet kit from NX:

What else is recommended?

Window switch, purge, bottle heater...? That it really?

I guess I'll just run a 100 shot instead of a 125 shot since 125 doesn't seem to be available with this kit.

 

Zex tps switch from AM

 

I have a zex wet kit.. Realistically you only really NEED the actualy kit, the other stuff is just reccomended..I'm currently running just the Nitrous kit and purge without a window switch, and ive had no problems, then again I also have an automatic. I think the window switch is much more needed for a stick.

Secondly, if you ever do wanna run a 125 shot make sure your fuel pump can handle it, along with your injectors. 100 seems to be the highest you can safely run on fairly stock setup.

There are cheaper alternatives to the bottle heater if you don't wanna get it right away, and id reccomend getting a pressure gauge.

If you want more info on nitrous itself, this is a good read:

Lastly..enjoy it, nitrous is ALOT of fun and a great bang for your buck. And you're gonna get a lot of "Holy ****" reactions. And on top of everything, Nitrous is a nice show piece! Have fun!
