The "right" cam timing does not exists.
The first rule in tuning.
1) EVERY CAR IS DIFFERENT!
The setting used on one car will not produce the same effects on the other, even though they are modified exactly alike. No motor is exactly like the other.
You must strap the car on the dyno and adjust the cam timing one tooth at a time and make a pass. Change only one cam per tun. Changing both the intake and exhaust cam at the same time will confuse the results. You will not know what produced more power or robbed a few ponies.

What your saying is very true, but his question is kinda vague.
a) Does he mean initial cam timing? (cam degree set in relation to the crank)
b) Adjusting timing of the cam gears as you mentioned?

I find that unbelievable. Prospeed and yourself have been buying so much stuff from them, thousands of US Dollars worth of stuff, turbines, piping, exhausts, you name it, and they wont even tell you how to correctly set up the cams?? 
That it's a SECRET? **** THAT! What kind of an attitude is that? They will sell you all of their overpriced stuff, but when you need a piece of advice, they REFUSE to give it??
Call them and tell them that we'll be buying Cusco and Jun stuff from now on. Tell them that my JUN camshaft kit comes with instructions and that JUN are always there to help you out.
As a general rule, the intake has advance and the exhaust retard. But I guess you knew that already and that you meant more precise settings...

Just spoke to Fair Import here in France. I told him about your problem and he offered to ask Junichi Tanaka to take a look at the HKS cams and to give him an idea of the ideal camshaft settings. Let me know if that would be of help of if you've already done that.

You could try this setting (IN 106.5) (EX 109)
That's what the HKS Evo Vll that currently holds the Tsukuba circuit record of 56.84 sec. sets their cams at.
550ps @1.9kg/cm
GT3037S
HKS 272 cams IN EX
820cc inj
HKS F-CON V
But ultimately I think you'll have to experiment on a dyno to find what works best for your set-up. Good Luck

i dont know about europe and awd dynos, but here on the east coast of the US there are none. the only places where i heard they have AWD dynos is out in Texas and out further west. so doing dyno testing can be somewhat hard without the AWD dyno.
