Post weird sound at low revs, turbo?

Hey everyone,

Had a VF34 installed bout 6 weeks ago, not long after i noticed a slight tinging sound sometimes at idle or initially as revs slowly build up (can't tell if it keeps happing after, too much noise) doesn't seem to be affecting anything but it is just playing on my mind any ideas or suggestings? I think its coming from the turbo but is too hard to pin point the sound.

Cheers

After revs build up i cant hear it any more, if its idling or when im cruising and revs are really low thats only time i hear it. so its standard with vf34s?

I Know some1 in town that has a vf34 i should find out if his does the same, he has a 2litre tho.

subaru wrx has a nomal low tap to them even my buddys 02. its not the turbo tapping its valve clatter its nothing to worry about unless the sound gets louder with higher idle also check the turbo gasket for leaks and tighten it down that could be the noise to mine made it wen i changed my up&down pipes cuase gasket leaks
