Bought my 2003 G35(V35 in Australia) 18 months ago and have been haunting this sight ever since. I have gain heaps of info from everyone so thanks for the help. Currently as it stands my mods are as follows:
Cosworth intake manifold
Test pipes with resonators
HKS dual exhaust
Jim Wolf C8 Cams
Greddy ultimate piggyback
Haltech dual wideband controller
Other suspension mods such as strut braces, Sway bars etc
Ultamite goal to run a vortech supercharger 9 or 10psi.
I'm fortunate enough to be a heavy equipment mechanic working on Caterpillar equipment at a mine site. So I have sound understanding, as well as tooling at home, to be able to fit parts and tune the car myself.
I have just installed the Cams and run up the engine with the NVSC unplugged and everything seems fine. As the C8 cams have 2.5mm of extra lift and about 30 degrees extra of duration will the intake valves hit the pistons when advanced or retared by the NVSC.
