Dont do it bruv
I know you have had a run of bad luck lately but has it really come to this. Is there anyway you can get round it, is there any information you can get from the Saab owners club as the Saab 93 has the same engine.
Although this article is not about a 2.2, it still contains some good advice
Turbo WoesIt would be a pitty not to see pictures of your Fronty on the Forum again .........
If I can be of any help please dont hesitate to contact me with a PM
Good luck
