Once you get the exhaust housing mounted up you can clock the center section of the turbo to where you want it. Loosen the band clamp around the center section to exhaust housing joint and turn the center section where you want it. Tighten it back up. Then squeeze the snap ring on the back of the compressor housing to rotate it to where you want it. Be careful not to squeeze it too tight or the compressor side can pop off, just enough to turn it with some effort.
