There are plenty of tubo chagred KAs making anywhere from 200rwhp to 504rwhp, most stock block, but many are built with pistons/rods.
As for the displacement thing...really, you can make more power with less boost due to more displacment. See below:
HP = [AP * CR * VE * CID * RPM] / 792001.6
Where: AP = Atmospheric pressure (~14.7 - add boost on top of this), CR = static compression ratio, VE = Volumetric efficiency, CID = Cubic inch displacement, and RPM = Well, you know that.
So you can see that if you add 20% to the CID (go from 2.0 to 2.4 liter) you can make up for it by simply adding 20% more boost, or increasing volumetric efficiency, or increasing the RPM, etc...
See herefor the source of those #s, and more...
