1. Not sure what problem ur talking about. if your thinking of carbon build up. the car is direct and port fuel injection.
2. You have intake, exhaust, headers and hopefully soon, supercharger. there is more but its best you search.
3. its a different beast once u hit the high rpms. think jekyll and hyde. once the secondary intake opens up it sounds like a different beast. i feel very special behind the wheels of this lexus.
4. no it has not been cracked.
check the threads for more info. im sure most of your questions can be answered from searching.
