Please help
I have checked all the piping and tightened them.
only happens at full throttle
don’t not happen when boosting slowly
Only happens on boost
car has 32000 Kms
2015 GSR JDM

 

Cant watch the vid but loud screeching noise only on boost sounds like turbo failure. Compressor wheel contacting the housing.

 

The rocker cover connecting to the intake was loose about to pop off. I tightened it back, torque has increased but the noise is still there when I’m trying to do a pull with now 90-100% throttle it is less though.

 

The car had been sitting for a few months before I bought it a week ago. Car is bone stock I am also getting rear diff slap. Car was in Japan and now it’s in Fiji. Could it be Fuel ? In Fiji we only have 91 octane and I am using octane booster.

 

it was the turbo
