1. what is the stock compression ratio for 1999 996 c2?
11.3:1

2. stock pistons are they forged?

Light alloy, pressed.

3. stock rods are they forged for billet?
Forged.

4. is stock crank shaft forged?

Yes, forged.

5. what is the piston ring gap on top ring?
Sorry, not specified in the manual

6. what are the factory camshaft specs?

The camshafts use Variocam so you might consider the camshafts from the X51 kit.

As a matter of fact if I were TCing or SCing a Carrera engine I would start with the X51 engine upgrade kit.

What year is the car? (i.e. 3.4 liter or 3.6 liter)
