Hi, I am brand new to this forum and recently purchased a 1999 GST Spyder. The car is complete stock for the moment. I am planning on going through everything before I mod it. I am mechanically inclined but this is my first tuner car and turbo car. Worked primarily on gen 3 Camaros and Harleys. Trying to get my kid into cars so we thought we would try a DSM and build it out a little. I have read many of the mod sections and are planning on going through the engine and replacing timing belt, plugs wires and other recommended items.
The one thing I noticed with the car that I was not sure of was when the car and turbo are cold, the turbo makes a screeching noise. It is considerably louder than the normal turbo whine when the car is warmed up and under normal operation. Is it normal to have the turbo sound this way cold or could I possibly have an issue with the turbo?
