shaman1204,
I'm assuming your car is a 986. Are you referring to removing the whole instrument pod from the car? If so it is rather easy. The link is for the OBC hack which includes removing the instrument pod.

If you are want to separate the instrument pod further once out of the car let me know, I can help.
I don't know if you can remove the OEM gauge rings. My car didn't come with them so I added them myself.
Best of luck.
