If i get 75 or 100 shot ofr zex or nx would that pretty much gonna give me the same number to the wheel? Is there a better brand? if so why?

 

NX kit has the best solenoids

 

no.

from what ive heard, zex measure at crank, nx measures at wheels. Therefore their jet sizes are diferent (nx>zex)

 

Uhh... No...

NX uses PFTE seals like everyone else.

 

from what i have learned over the years, they are all about the same, from the larger manufactures, NOS, NX and Zex, but, i have had a lot of issues with different NOS bottle heaters, i have had some NOS relays go bad, i dont personally like the Zex box that they use. i have had and installed many nitrous express kits with no problems. i personally like the feel and quality of NX so thats what i will continue using. im sure there are stories for all of them, both bad and good. im sure its a Chevy, Ford thing...

here are a couple more reasons...

+1 for nx. ill be installing those cf capped bad boys for my stage 2 this weekend.

 

I have a Zex kit and my solenoids are not in a box they are pretty large though.

 

I only buy NX. Others have good luck with other brands, but I wouldn't buy anything else.

 

yeah , i am not talking about the solenoids in a box, a lot of the zex kits have a control box that has a tps and some other things in it to control their setups. i personally just dont like how it works

i have had good luck with most all of the kits but the fewest problems with NX.

i think if a nitrous setup is done correctly, there is little room for error...

 

NX solenoids are guaranteed for life. No one else does this.

You can even send them in every year for a free rebuild.
