I for one, don't want to drive everyday with 800hp out of either engine. It would be rediculous. I will hit 300, and if $$$ permits, 350hp. This, in either engine, will drop into the low 12's.
But to glimpse the strengths.
Sr - high revving.
Ka - Torque.
Weaknesses.
Sr - Aluminum Alloy block with Steel Alloy cylinder sleeves. (Wow. Steel Alloy. HAS to be 1/2 as weak as iron.)
Ka - Lower redline, less horsepower.

Now. Before people bitch about my less horsepower claim. I am talking two engines with the same mods. The KA will have less horsepower, but a lot more torque.
Each engine is for the right perspective owner, and people need to realize it.

Well, you should just say less hp for the KA. What you need to do is to make the distinction that it will have less peak hp.

The KA typically have a much broader powerband than the SR. Not a huge difference, but significantly enough...

Case in point:

two 240SX, both dynoed 210rwhp at the 1st annual 240SX national meeting in Kansas City, Mo. One is a S14. The other is a S13. The S14 is running a F-Max stage 1 on an engine that has 100k miles on it. The S13, well, about 30k miles.

Since both cars have the same peak rwhp, it was thought it would be a good comparison. the S14 has about a 400lb weight disadvantage.

After three runs, the S14 with the KA+T came out on top on all three runs. Wasn't a run away victory, but a win nonetheless. Yeah, both have same peak rwhp, but since rwhp doesn't tell the whole story, and that the heavier car won means that the KA+T made more power through out more of the powerband, and torque is part of all that... HP is a function of torque and rpm...
