i dont know what you have done to the motor but all nitruos kits are made to work on a stock motor the one thing you have to do is change to a colder spark plug. on an NGK plug you would need to go non platnum and the plug # is BKR7E, or you could go with a DENSO Iridrum plug they are more money but they are worth it they will last you much longer. and a 50 shot will be fine with just the plugs but if you wanna go like 75 or a 100 you would need to put in a new fule pump i would go with a walbro 255lph pump. on the kits you could go with any kit but you make the best wheel power with like an NX kit or a ZEX kit

 

Yeah vteccrx909 is right on, If I was you id get a fuel pressure regulator just to be safe, but not necesarry unless your running anything over 60shot, then you would also need too look an after market fuel pump and maybe retard timing. But definatly get the colder plugs, and DO NOT get a Zex kit, the are the easiest to install but they suck. They make the lowest hp and they are all dry kits, which tend to overload the injectors and cause them to fail, if this happens while spraying, bye bye engine! Get a NOS wet kit or NX. I used to have a NX wet kit on my Si before it got stolen and I was very happy with it. Just do some reaserch and use common sence, nitrous is just as safe as other forms of FI if used properly. Hope this helped.
