The ka is a good engine. I honestly cant remember the hp # off the top of my head but it was like 430whp but the tq # is what sticks with me. And it was 455wtq on a s14 ka24det we made the other day on a tuned stock ecu in the shop owners car. All the engine build is 740cc injectors, z32 maf, forged pistons and stock rods.... Its a pretty strong engine........

What turbo?
If your going to raise compression, dont stroke it. If you get a bigger stroke then youll get small length rods. So your CR could possibly stay the same. I was thinking about this kind of build to but your really going to have to watch AFRs and tuning will be more critical. Im not sure about Srs but theres a few vehicles i have searched running high compresion + Turbo (I fogot the name of the Japanese NSX..SCCs Focus and other..)
But i agree your effective CR has to be different/higher to make more power, but cylinder pressure also come in to play.
Becuase of Holsets i think using compressor maps has lesss of an importance but you stil should use them. Just to make sure your out of the surge line and close the highest efficiency as possible.
But i also agree, as to its retarded where they say turbo "X" makes this amount, though you MIGHT be able to figure out a max for a specific engine.
Basically all this can be summed up into 2 charqcters
X2!
