Howling turbo

I am a newbie to the Typhoon world. I am in Tokyo and just bought a 92 Typhoon, for a good price. It has very loud howling noise which seems to be coming from the turbo, only when there is any boost. It almost sounds like a siren. I removed the intake hoses and check the turbo impaler. There appear to be very little side to side play and no in/out play. The main inlet hose was very dirty with oil and debris caked on inside. Debris seems to have come from the broken end of the filter-to-turbo piping.
The in-dash gauge reads about -10 at idle and the noise start any where above 0. I searched the archives but found no similar noise or symptoms. I fear bits of the piping broke off and damaged the impaler. Does this seem plausible? Any suggestions will be greatly appreciated. BTW there a few good ones left over here.
