As we are speaking about it ,

Here is a picture comparison between a K27-7200 and a GT35.

So far, the hot side seems to have nearly the same overall dimensions while the cold side is definitively much larger on GT35.

Hot side here :



We must consider turbine efficiency it self.... but from the size of body, I think the handled exhaust flow speed are not such different.



Cold side here :



So far, the GT35 has a much bigger cold side than the K27-7200.

From these picture and from some reported experience, I strongly believe that the GT35 need also an increased wastegate flow in order in order to reach the same boost level.
