racing camshaft upgrade for G37 coupe

[abice]

Does anybody know if and where you could get upgraded camshafts for G37 I believe they have them for the G35 and for the Nissan 370z but I thought that the VQ37 was the same motor in both the 370z and the G37's if this is the case then why can't I purchase camshafts for the 370z's VQ37 engine and put them on my G37? I dont know just wasn't sure if I had to do that or they had specific cams for the G37.

I'm fairly certain that you can...the only differences between the 2 engines is that the 370z has a better intake/exhaust setup.

Any info from the techs?

There is no current aftermarket high performance cam solution for the VVEL engine. Nissan's 3.7 liter VVEL valve activating system is very complicated. It does not use a camshaft. To change lift and duration, a stepper motor controlled by the ECU rotates a shaft that moves the fulcrum of a rotating eccentric shaft that works on finger followers that move the valves.
