Talking strictly about the turbine side; Is there any real difference between the hx35 turbine wheel and the wh1c turbine wheel? In other words, if both turbines had the same size housing would one be any better than the other in terms of restriction and efficiency at transferring torque to a given compressor?

 

From what I've heard, they're identical. However, I've never actually directly compared them.

 

Thanks for the input.
