A lot of white smoke!! and now car won't start
When I took the Porsche out today I quickly notice a lot of white smoke pouring out of the exhaust and car was running very rough. I immediately parked the car and tried starting it again and now it wont start unless I give it a lot of gas.
What could be the problem? I'm thinking head gasket, but I haven't ran the car in about 2 weeks and I check the oil a day ago and did not notice any coolant.

That is the same exact thing that happened to me and now I am just about to put my new head gasket in and put the everything back together. Was it running hot?

Is it smoke or steam? Does it smell sweet, or like burnt oil? Does it smell like gas?
Sweet:
Start the car for about 5 seconds.
Pull the spark plugs, and with a good flashlight, look down into the cylinders. There should be one that is wet if you have lost a head gasket enough to blow steam.
Oily:
Don't run the car. If it is oil smoke, you could have a broken ring and lost compression. The cylinder may have fouled, causing the hard start. You should see a good amount of oil in 1 cylinder to cause a ton of smoke.
Gas:
Could be a failed open fuel pressure regulator. This would cause too much fuel pressure, making the injectors hard to open, or stay open flooding the cylinders. Fuel gauge is needed to check this.
Pull the plugs and let us know!
[edit] Forgot about the plugs. One should look different from the others. Oily, or wet, or steam cleaned. That would be the bad cylinder.

I give that a try when the whether is fair, hopefully tomorrow. It's kind of hard to tell exactly what the smoke smells like. I'll keep you all posted.
