Can someone tell me if there is a difference between an S5 NA OPM and an S5 TII OPM?

Turbo II Rotor

They are the same.

The mechanical ones on the series four cars are different with different flow rates. The series five are the same part number for na and turbo and I think this is because they are electrical and the ECU's can determine the flow rates. I'd suspect the flow rate for a turbo is more than for the series five na. ECU determines that.

Thanks guys. I remember hearing that the TII OMP had a higher flow rate, so I assumed that it was a different pump. Thanks for letting me know that the part #'s are the same between the two. That assures me that the difference is in the flow rate via the ECU.
