Here's an example as to why using U.S. Generic single nozzle kits don't work:

This vid shows a Zex wet kit shoot right up against the throttle plate and you will see that the nitrous blows right past the forward cylinders all the way to the back. This will have a high chance of breaking parts, even though the dyno shows the proper results. The back cylinders will be processing far more of the nitrous charge and will most likely overload or detonate.
Use a WoN system!!!
