Looks good so far, great job tackling this project yourself!

I think S&R uses the V-band turbine housing though. Those are small (T3) housings...compared to this 1.15 a/r T4. IMO the T3 housings and the V-band are too small for the VQ37VHR, as they don't flow enough. I did a bunch of EBP testing, and know that the T4 is the only way to go, since these engines have a very high VE even at 7000rpm. That is a lot of exhaust gas you are trying to push through, so the housing has to be large.
