[911TE]

To add some more information and questions to this thread:
I did the cam timing on the weekend by setting the RS-cams to the 993 RS factory manual value of inlet opening at 5 degrees BTDC at 1mm play.
(993 standard is 1 degree BTDC)

The inlet valve is then aproximately 1,8mm open in Overlap TDC.
As John suggested, around 114 degrees after TDC it has the max. valve lift, but this is nearly impossible exactly to measure, because you can turn the engine around 4 degrees at max. lift without reading different values.

The only strange thing is that I´m not able to set both sides at exactly the same lift and the same begin of opening.

On the left side setting the cam exactly on 5 degrees BTDC begin of opening (1mm lift) gives 1,8 mm lift in TDC, on the right side 5 degrees gives only 1,7 mm lift in TDC.

If I set both cams to 1,8mm in TDC, the right side opens 4 degrees BTDC. (left 5 degrees) Which value is more important in real engine life?

Is this a machining tolerance or do I have a mistake in my measurements?
