From what I have heard but haven't seen yet is there is a company that makes a plate for nitrous for the GSR and preludes to replace the butterfly unit on the intake manifold, does anyone no what company this is? sounds like a good idea to me thanks

 

NOS makes a plate kit for the gsrs. talk to roby

 

its NOS. they make a nice one for the gsr, the prelude one however is below par. your other option is direct port, 4 fogger system, my personal fav. i dunno which car u drive but if u need help im more then willing, aim robycold.
btw, the gsr kit is nice ,, only prob ive seen is one guy recently melting #4 spark plug after every run ...id rather go dp..plus it looks hard lol.
just im or call me and ill get u some awesome prices...
