i have a D16Y7 to and i want to get a cam gear. how much of a difference did it make on your car? if you advanced the timing don't you have to use higher octain gas? did u put it on yourself and if so how hard was it?CiViC2000 said:i just got my cam gear and i put it on and advanced it two degrees. i dont think it did a whole lot, so if anyone else can reply, i was sort of wondering the same thing. sorry i couldnt help, but thats what i did. oh and i have the d16y7, no vtec, im sure that makes a little difference.
