Alright I found a car i'm about to buy, 1999 GST w/40,000miles, stock car except down pipeand exhaust. The concerns i have are when I started the car it makes a rattling (like BBs in a can) up by the turbo or possibly in the block.It does this every time i start the car and i noticed when i drove it, in lst gear it makes a noise almost like a crackling just while i'm excellerating to 2,000rpm then it goes away. Last questionable sound is the the turbo winding. I have been in like 4 turbo cars and they have never sounded like a pig squealing/wheeeeee noise. What do you guys think this could be.
 
The squealing noise could be a decent sized boost leak. Check for leaks. As for the first noise, I'm not sure... sorry :confused:
 
I have seen a similar thing in a few other cars. First, sometimes the alternator can make some squeaky noises on startup but BB's in a can sounds more like an old resignator or cat converter. You said it had all new exhaust so perhaps that isn't it... but thought I would add my 1 cent.
