Hoon

Hi from New Zealand Has anyone put nitrous onto an RS200Z? Im thinking about it for mine, at the moment it is standard and im finding it hard to find anyone in N.Z thats done this sort of work on an Altezza. Im wanting to know what sort of setup I need for it to be reliable and not blow it . I was thinking maybe another 50HP would be nice Im also sick of hitting the 180 km/h engine cut. Is there a safe and easy way to disable the cut out?
