I just replaced a '93 Mitsubishi turbo that sounded like a jet engine spooling up loud enough to get pedestrians to turn and look. The sound was very cool if you like that sort of thing. It was slow to spool up starting with a very low pitch and only reached a little above base boost with no other discernable problems like bearing play, etc. I think the wastegate door did not fit quite properly but am not sure if that was the cause of the noise. A search on turbo noise turns up a day's worth of reading and plenty of suggestions, mostly among diesel pick-up guys, looking to make their turbos loud. Among them are intake and exhaust mods. In my case, it was definitely the turbo itself since the replacement is very quiet and boosts quickly with no other changes to the car.
