on a j-spec gsr motor with all the bolt ons and some skunk2 cams(not sure what stage to get just yet)..should i get the cam gears while im at it or not worth it..also will it mess up the motor if im running nitrous cause i heard your not supposed to use nitrous and advace the timing?? thanks much

 

if you plan to get the car dyno tuned, I highly recommend adj cam gears along with an FPR, they make a huge difference in power. Just let the tuner know that you're going to be squeezing, and he can take the necessary precautions.
