Custom turbo
After looking at compressor maps and the actual specks of both the S200 and GT2556V turbos, I have decided that going with a 50mm S200 and putting the GT25V turbine housing on it would make a better turbo then putting the s200 compressor on the GT25V frame.
I am going to have to modify the S200 turbine wheel to fit in the GT25V nozzle ring, and I will open up the turbine housing as much as I can to allow for a larger turbine Exducer diameter.
