I have an 02 that i bought a NX xpress kit with purge/NOS progressive box/msd window blah blah blah. is it worth putting this thing on or should i sell it and get a stretched arm and an air shifter kit? nitrous seems to look cool and make you go fast, but is it worth the pain to install this kit? low 9's like 9.4 or better is what i am aiming for on a stock motor. if i keep the bike after next summer i will do a big motor but i am contemplating selling it for the 04 zx-10r if it looks like the photos. what do you all think??
