Stock RB25 turbo:

Compressor  
48mm inducer x 66mm major compressor wheel in a .60 A/R compressor  
housing.

Turbine  
51mm inducer 43mm exducer in a .5 A/R turbine housing

Stock RB20 turbo:

Compressor  
42mm inducer x 59mm exducer in a .50 A/R compressor housing.

Turbine  
51mm inducer x 43mm exducer in a .4 A/R turbine housing.

\*\*rb25 turbo is slightly better, get a gt3071r and that will be MUCH better 🙂
