Does anyone know between what lift values the stock durations and centrelines are measured at by nissan? I have read that it is between 0.4mm lift (0.016") but if someone could confirm that would be great.

I haven't measured the cam gear to check but I would estimate if the diameter is about 100mm then circumference is 100mm x PI = 314.16mm put that under 360 cam degrees gives 1.146 degrees per mm or about 2.3 crank degrees so your cams would both be about that far retarded. Also the cam chain is not vertical on the tension side so there will be a minor trigonometric correction too if I had the angle from vertical.

Now comes the part where you tell me that's for a DE and the VE is totally different???
