ROAD/RACE- Turbo my 08's NUTS
Both Audi's 2.0t and the mazdaspeed 3's engines do have high compression ratios for turbo engines, but they are using direct injection. That lowers combustion chamber temperatures and helps them get the better air-fuel ratios. The fact is that we will not know how our pistons hold up until some one breaks one or throws a rod.

It's all about chance. If you leave your car alone, something might break tomorrow. That's why there's a warranty.
If you have a turbo kit, something could go wrong as well. Some people install them incorrectly and damage their car. Sometimes a part breaks (example: my friend's Fuel Management Unit died so his turboed motor broke because it wasn't getting gas). Sometimes you try to use too much boost and the motor can't take the strain. Sometimes everything works perfectly fine until the day you die.
Nothing in life is guaranteed, especially with cars. Leaving it stock allows you to know that things that go wrong or break are just chance. Usually, the warranty will cover those things.
If you modify your car with a turbo kit, you are taking chance into your own hands. If something breaks that's related to the turbo, it is now your responsibility to fix.
The best advice I got came from my friend (who has run a car modified with a custom turbo kit for 4 years now): go into the project planning on your motor dying. If it does die, then you were prepared for it. If it doesn't die, then you got lucky.
In the end, you have to decide if you can take on the commitment of time and money it takes to keep a turboed car running. It's all up to you.
