GT-30's come only have one variation in compressor housing, and thats 0.70.
There are three variations in turbine housing though, 0.63, 0.82 and 1.06
The ratios are sometimes on the inside of the housing but still visable without pulling the turbo apart.
A "GT30 500HP TURBO" will most probably have the mid range 0.82 compressor housing
