How old is your head gasket, that's typical failure symptoms... I thought it spewed its coolant on the dyno also... I'd bet on general hg failure, you'll never lift the head on a stock turbo... When the head lifts big style you tend to fill the head with air, and it instantly boils over, sort of 110c+...
If its the original gasket, change it, then see what happens, probably be fine for ages...
It's the peak cylinder pressures midrange that f*ck head studs, when you make chronic amounts of torque at lower rpms, the cylinder pressures are mental...
Remember, 28psi on a stock t2 does not equal the airflow of a big turbo at 28psi... My car makes 175hp at 22psi...
