Q: does nismo make camshafts for the 350z, and do camshafts require adjustments or what?
A: Nismo does make cams for the Z, but keep in mind that the VQ is already tuned very agressively on the Z. Keep in mind that the nismo cams are part of the "r-tune" line which will void your warranty, plus it only gives you very mild power gains so it may not be worth it.
