Was this the one on ebay?

How much did you get it for?

That chattering too also - has it got a dump valve fitted? It could damage the turbo as in effect the turbo blades are stalling as you come off the power.

Yes mate, It was advertised on the bay. It has a dump valve fitted and it chatters. If the turbo brakes i'll replace it with something bigger . Until then ill continue to jizz my pants everytime i let off lol!!

Pretty sure thats the turbo making that noise, not the valve - be wary!. How much did you get it for?

Was looking at this myself.
