As AllWheelGrip says the oil change services are vital as my 1.8 t engine sludged up and nearly seized it. Had to have new oil pump fitted to sort it out.
Apart from that they are a good strong engine and should do many miles.
Let the turbo run on after boosting a lot before you switch off. It spins the oil off the blades and will prolong the life of it. (Pretty standard advice with any turbo car).
