My (early 04) has 65k on it and the 10 vane turbo seems to be making a little noise, sort of a bearing noise only under wide open throttle. It has always made more boost than it should have,it use to spike when you first floored it to about 35 psi and then it would drop down to 30 (Innovative xtreme street). Several times and even more frequent recently, when you floor it it will spike to about 50 psi and just stay there sometimes. It actually wraps the needle on the gauge all the way past 35psi around to the pin at 0!!!!! When it is stuck at 50 psi the power is understandably low. I assume the blades are sticking. I think over speeding it may have trashed the turbo. I have not looked at it yet but has anyone noticed any bearing noise from their turbo prior to a complete failure? I am not talking about the normal whistle.
