i just pulled my tranny the other day and i started the car for the hell of it(maybe a bad idea?) and when i revved it it would make a squealing type noise that made me think it was the turbo bearing. i thought that maybe it's cause the engine sits low in the back and high in the front without the tranny and the fan was hitting the shroud but no. if you have heard jim testa's exhaust sound clip it sound kinda the same when he revves it. thanks
