I sure would love to get my hands on an ISV to design parts for it. Can’t take my pickup out of service.

I think the ISV in our titans would benefit from a true parallel turbo setup, one on each bank. I think there is enough room too.
 
I have a turbo core I was going to have rebuild and change out wheels. Couldn’t get nobody around here to touch it.
Would you be willing to take some measurements? I would like to find maps from turbos of similar sizes and compare them to the efficiency maps that are in the ecm. I need a better understanding of how these turbos interact, especially running so much less boost I may need to move the transition point.

I really would love to know compressor wheel diameter, the whole wheel diameter of its out. Approximate diameter of the turbine inlets in the rotary valve, the turbine outlet diameter, and the whole wheels if accessible.
