Vary your speed, avoid hard braking, avoid luggin the engine, avoid redlining the piss out of it (its useless anyway - power drops off well below redline on this engine anyways) -
I would stay away from dropping the clutch, riding the clutch, grinding gears, and driving like a granny or a thief...
and give the turbo time to cool before turning off - did I mention vary the driving .. and finally avoid heavy stop and go....and long WOT runs ,,, ok one more time: vary your driving
