The powerband on the KA is regulated largely by the camshafts that it uses. This is proven by the s13 motors redlining at 6700, and most of that is useful revs. The s14 with milder cams redlines at 6500, and starts to take a crap at 5700. Once you swap out cams, you can have power all the way to 7000 and still be pulling.
As far as the turbo sizing, you're right.
