[s-cars] Turbo....anyone have a loaner or one for cheap?

[Peter Golledge]

Start with a boost pressure gauge... teed into the line that feeds the 
ECU, that will tell you the boost level your are getting.

You can access the cold side of the turbo easy enough to check for 
damage/play.

Start with those two things... there is also infant mortality it might 
be that one of the recently replaced components is bad/intermittent 
bad.  I'd start with the above though.

So, seeing as the turbo used to at least "scream" (literally) for the last 90K miles (since I bought the car) and now doesn't even whimper or slightly whistle, I think that is my next plan of attack.  A few questions....

Anyone have a stock AAN turbo collecting dust somewhere that they are willing to let go cheap, or willing to lend to me so I can at least see if this is my issue, then I can either source a decent used or rebuild mine?  I am unfortunately not having a second vehicle to drive while I figure this out, and need to drive this baby everyday to work.  I am vigorously searching for a second beater vehicle, but have not come across the right deal yet.
