I have ran a Zex Nitrous kit for many years and never had a single issue with it. it has worked perfect every time I went to spray it. I never ran a big hit so maybe thats why I never had any issues. I ran a wet kit off the fuel rail. I ran the shark style nozzle.


On my other vehicles. I always ran a RPM activated switch. you just put a pill in it with what RPM you wanted the nitrous to kit on at. i always had mine come on around 3200 RPM's I would load the vehicle up to 3k rpms before I launched and it would kit quick when I dropped the clutch and came out of the hole hard. Nitrous is fun. but gets pricey if you want to run it all the time.

 

ZEX is a nice kit. I ran ZEX on my 08 titan. Easily installed, clean under the hood , newer style silanoids where everything is contained in the ZEX module. Only down fall was there purple bottle took a long time to heat up and took forever to build preasure. keep a torch handy and even at that it will take u ten minutes. After all my goodies with the kit i want to say i paid 1100. Im sure theres cheaper kits of same or better quality but the titan forums liked the ZEX so thats what i went with.

 

newbie her to nitrous.
The proton kit will fit a 07 5.3 Avalanche?

 

Yes I will work just fine on there.
