How can you tell when the fins inside the turbo is touching the walls? Is it possable for it not to make a sound? becasue when i turn the wheel on my turbo, you can hear a sucking sound from the center turbo were the feed line goes...

 

Another question that i have is, Does the Turbine on the exhaust side sopossed to be 100% centered?

 

does your turbo have any side to side play, if it does, push it side to side and spin it at the same time and if the fins hit the housing then its junk

 

im guessing that the turbo is good because it doest hit the walls when i side it and turn
