plenty of motors out there can run sky high compressions and run 91 pump, but NOT A KA
KA also itself has thin cylinder walls. and a weak head

So.. you're telling me that the motor dictates the compression it can run? Ha. Haha. What a joke. Go read a book about tuning - then come back and join the grown-ups in this discussion.

And.. the KA has thin cylinder walls versus an SR.. but - the KA's is iron, not some aluminum-magnesium conglomeration. Strength for strength, I'd bet the thick weak metal and thin strong metal are nearly the same.
Weak head? Compared to what? You have a weak head. Come to this discussion with proof and not assclownery, or go join the kiddies over at NICO.
