00 Saab 9-3 2.2 TID wont start..
 

Hi there,
I think ive killed my saab :(
Its a 9-3 2.2 TID with the owl vacuum powered egr valve (115bhp engine)
I was trying to max my SAAB (stupid thing to do)
it got to 180kph (110mph) then bang (heard from the engine bay)
so i pulled over and had a look, couldnt see much as it was night.
got back in and nursed it home, didnt feel right at all, was like semi boosting randomly and had no power at all.
got it home and knocked it off for the night.
looked at it in the morning and i found a hose connecting the intercooler to the turbo was slightly off so i popped it back on and attempted to turn it on.
turned over fine but wouldnt fire up.
any idea as to what ive done would be appreciated.

Thanks a mill
