If you do not intend to mod the car and you are leaving the engine as it is, a good FATT (fully automatic turbo timer) is all you need. A FATT will detect temperature levels and sets the turbo timer accordingly to keep your engine running long enough to cool your turbo down.
Since it is a new car, I suggest investing in a good alarm system first before proceeding to buy any gadgets. The more gadgets you have, the more inviting to thieves your car will become.
Just browse the Car Crimes thread to get an idea of what I mean. :X-:
By the way, congratulations on your new car. :regular_smile:
