It wasn't installed correctly if it is the exact same turbo.

 

Look for a gasket leaking, an intercooler fitting leaking or your wastegate being stuck open. Maybe the actuator hose isn't plumbed correctly or the boost solenoid isn't plugged in.

Have a read up on how the actuator works and how you adjust it before you go swapping it over.

 

Here is the turbosmart iwg instructions. Here is a youtube clip showing how to adjust the preload.

 

You will see that if the actuator is not adjusted properly the wastegate will not be sealed shut.
