| You need to have a tuner properly tune your Z for running nitrous.. The NA ECU runs around 32-34 degrees of timing at WOT. That is simply far too much timing if you are running spray.. even for a 60 shot. The frontal cylinders do not wear out under normal conditions faster than the trailing 4. Our engines are port-injected EFI systems so each cylinder has it's own fuel injector to ensure equal fuel delivery to each cylinder. If you use a wet-shot nitrous system, the additional fuel coming from the fogger nozzle will not equally distribute into each of the cylinders. The nitrous oxide gas WILL pretty equally mix in with the incoming airstream through. The atomized fuel coming from the fogger nozzles are subject to inertial effects which result in the combined effect of the fogger nozzle's high-velocity ejection of the gasoline combined with the constricting effect of the throttlebody that further accelerate the fuel droplets into the plenum chambers, the fuel tends to carry past the front runners more leading to a leaner condition in #1 and #2. That is why I say you will want to keep the shot low, around 60HP total for a wet setup and jet it on the fat side to ensure that the front cylinders aren't running too lean. A 70HP shot should be fine as well in a wet setup with TB foggers.
