what do i need when i get a NOS System?..extra injector or bigger injector?...high comp piston?...

 

depends on how much of a nitrous shot you want to run. honda motors can handle up to a 70-75 shot with everything pretty much stock. it's always nice when running nos to get a better ignition, maybe a fuel pump, and a fuel filter. if you want to go with a bigger shot, say 100 or so. you would have to build your bottom end with rods and pistons and if you go bigger i'd look into getting the block sleeved, plus getting your motor tuned for that application. hope that helped.
