How do you set timing to TDC?
I was running through the instructions for the supercharger kit and I ran into a brick wall when it said, "set engine timing to top dead center" right before you pull the crank pulley. I have no idea how to do this, anyone give me an idea?
I was also concerned when it said to "transfer timing marks from stock crank pulley to new crank pulley". Is this as complicated as it sounds, or am I just scaring myself unnecessarily?

If the pulley is still on, line up the yellow tick mark with the front cover pointer (might have to clean up the aft part of the pulley to find that mark).
Then figure out how the new pulley is going to bolt on (line up the 4 bolt holes with the installed pulley), hold it in place against the original pulley, and copy the marks' locations...

What do you adjust to match up the marks? I know it has to do with the CAS, but do you need a wrench to adjust it, or do you turn it with your hand, does it spin around when your trying to adjust it? not to sure.. I'd like to know about this as well.

Well, the easy way would be to know that the timing marks on the pulley are 5 & 20 degrees ATDC on the front rotor.
The pain in the *** way is as follows:
Pull the plugs.
If you want to find TDC for the front rotor, rotate the e-shaft until you see a tip seal of the rear rotor in the leading plug hole. Rotate until you see the same tip seal in the trailing plug hole. Half way in between these two positions will be TDC for the front rotor.
