ZEX or NOS?

I can't make up my mind on which is the better brand for our cars.
Any recommendations?

I found a site that sells a Nitrous Kit specifically for SC'd or TB'd cars. It's called Cold Power made by Cold Fusion. Anybody heard or used it? So far the leading brands seems to be NOS, ZEX, NX, and Cold Fusion. I sure need some guidance on which is mos suited for MBs.

Would you happen to have the model number? The most expensive one seems to be the multi=stage kit that sprays at WOT and then again by using a switch on the dash? Is ZEX the most advanced in terms of technology?

The ZEX kit has the solenoids built in to the control unit. This means that you only have to mount one box, vs with the NOS setup you have to mount the control unit and 2 solenoids. Either kit will be fine and the outcome will be the same. However, I prefer the nozzle on the Zex kit.

You will want this one.

See how small the control unit is? Very easy to hide.

Start off small and spend about 3 hours on the dyno tuning the kit.

With a 35 shot, I picked up 40HP and 60+Trq at the wheels.

I am surprised no one has made a module that interfaces with the computer to retard timing.
