944 s 2.5
intake opens 4 degrees after TDC
intake closes 40 degrees after BDC
exhaust opens 36 deg before BDC
exhaust closes 4 deg before TDC
----------------------------------------------------------------
944 S2 3.0
intake opens  3  deg after TDC
intake closes 47 deg after BDC
exhaust opens 39 deg before BDC
exhaust closes 7 deg after TDC
--------------------------------------------------------------
968 - BASIC TIMING
intake opens 7.5 deg after TDC
intake closes 52 deg after BDC
exhaust opens 31 deg before  BDC
exhaust closes 1 deg before TDC

968 - TORQUE TIMING
Intake opens 7.5 deg after TDC
intake closes 37 deg after BDC
exhaust opens 31 deg before  BDC
exhaust closes 1 deg before TDC

from what I understand on the  968 as its a vario cam engine
the difference between BASIC and TORQUE timing
is this  
Basic would be if you had the engine on a stand  

and Torque is the timing that is when the engine is running and under the control of the vario system

also  
the physical dimensions of these cams are all the same as far as length -  position of sprocket - and position of the journals where the cams mount-
hope this helps  
and I'
ll also post this info in the TECH section
