your take on BOV's and WG's
I think what we are going to find out here....and I know because I used to work for Cummins....is that a HX35/40 for a 5.9L or 6.7L Diesel MAY have a T4 exhaust flange, but the A/R of the housing is AS IMPORTANT as the exhaust EXDUCER size.
The reason is:
A OEM Diesel has a RPM range of 900-4000 rpm.
Bore x Stroke = 5.9L 358ci or whatever.
And the calculations for the Amount of Air for Diesel Application.
Yada yada.
When you take into account 2 extra cylinders, and another 2500-3000 of desired rpm....you will see that THAT particular turbo Exhaust Housing is drastically undersized.....and will be going positive on a V8 application at or around 1800-2000 rpm, and running out of turbine flow around 4500 rpm.
Good luck though...prove me wrong.
