Specifically for the Boss Sr. turbos....

Compressor Wheel-
What is the difference between the 60-1 and the GT61 wheel? I know the GT61 is rated 15hp more.

Turbine Housing-
What are the differences between the Stage 4 Vs. Stage 5?
Is the actual turbine housing a different size or are the turbine wheels different? Or both?

Obviously the Stage 4 will spool faster so I'm assuming that the only difference is the turbine wheel.
