Supertech Pistons...

[StryfeS13]

Why does this say it's for an S14 only?
I was under the impression it doesn't matter, since the dual cams in the S13/S14 are pretty much the same...?

Pretty much all I'm asking is if I can use these for my S13 KA24DE. And is 10.5.1 compression too high?

going for a mild 280whp build.

You don't increase compression when you're adding forced induction, you decrease it. For every full point of compression that you remove you can run 2-3 more psi without knock for any given octane ratio. That's right from Kenne Bell.

I'd run 8.5:1 if I was given the choice. Also, the S14 and S13 pistons are the same. The only difference would be the SOHC pistons from the KA24E.

So yes those pistons would work, but not for boost. Unless you're running meth/water injection almost the the entire time you're on boost.
