If you're talking about being able to rotate the CAS, I think so. There are three hex bolts that hold it in place. It seems that if you loosen the bolts, you can then rotate the CAS. I THINK.
I searched and read that stock timing is 15 before TDC. Got it from here:

I don't know if that's true since no one verified it so I'll have to look it up to double check.
EDIT: Here: http://www.nissanperformancema...sarah/ it says 10 deg. BTDC for the DET (which I have) and 15 deg. BTDC for the DE. Crap...I'll just look at the FSM...
