Wondering whats so wrong with the standard IHI turbo the RHB6 and are the components from a RHC6 interchangeable. As parts availability seem to be an issue for the RHB6 as I have not been able to find impeller shafts and turbine impellers for this model.

The RHB6 is a dead end for parts. It's also not very efficient and I'm unsure exactly why.
The RHC6 is a big unknown, but possibly also a dead end for parts.
