I just turned on the car after doing all the piping for the intercooler and when i went down the street i heard this screeching. Which I know is the shaft hitting the housing. So the turbo is bad. But is should still boost a little, right? I have an internal wastegate. Could it be leaking that is why it is not showing any boost? Let me know what you guys think.

 

help

 

ahh this sucks....dammit...

 

Here's a reply, I have no Idea but good luck...

 

If the blades are hitting the housing then it's certainly not going to create enough boost to pressurize your charge pipes / intake manifold
