When I get up to speeds of 60mph or greater sometimes my turbo makes a spinning metallic sound I was wondering if this is normal or could it be a Turbo problem also sometimes my car makes a chatter noise at high speeds but I can't tell were it is coming from can anybody give me some advice?

there is a lot of sounds, it be cool if you could record it. When I need to record engine, I use a recorder and external mic, and tape the mic to the intake tube. Best sound ever.

well sounds like your turbo is just spooling up. What kind of car is it anyways???
