Assuming this noise started after replacing a turbo, check the turbo is bolted down correctly; I had a high pitch screaming noise from my turbo (especially when cold) turn out to be the 4 bolts holding the turbo to the exhaust manifold where loose.
Correction; this was under boost condition, obviously your noise may or not be.
