2021 Turbo vs 2020 Turbo

I recall hearing there is a difference in turbo size between the B58C and B58D, with the D being larger. Can anyone confirm this?

Articles or part numbers would be appreciated thanks.

I’m not certain about impeller size or turbine size, but I can assure you the part numbers are different as the 20s have the dual port housing and the 21s have a much more normal turbo.

Can you explain what you mean by, "much more normal turbo"?

I didn't find anything peculiar or odd with the 2020 turbo setup, aside from it being a dual port.

Thanks,
