VVT timing adjustment?

[kjb_r33]

I know this has probably be mentioned before, but i couldnt find it anywhere, so if any one can help it would be appreciated.

ok, i know the solenoid for the VVT is turned ON at around 1200 rpm and turned off at 5000 RPM if the engine is under load. What i need to know is at what variation this cause's the inlet valve timing and also what is the static timing for the exhaust valves. (Exhaust closes ATDC as well as overlaps).

I havn't been able to find anything about valve open and closing, only durations.

these are of course stock cams, on a R33

Any help would be appreciated.

C'mon guys, surely someone knows the stock cam specs.

For a R33 RB25DET:

Inlet:

Opens @TDC, Closes 60ABDC, Duration 240, Lift 7.80mm

Exhaust:

Opens 57BBDC, Closes 3ATDC, Duration 240, Lift 7.80mm

Overlap = 3

There is all the info up on the Tomei site (can't recall the exact address).

And when VCT solenoid is on, the inlet timing is advanced by 20 Degrees
