Ive yet to hear on hear of a aftermarket piston ring lands cracking. My SR running Wiseco Pistons see a fair share of high 80's knock, been running like that and drifting it for 3 years with no issues at all. Just needs a retune.

Companies could save money and material if they could use thinner ring lands. But they cant cuz a thicker ring land is required to withstand the power.
Of course it's not the only reason. But notice I wasn't just talking about any ringlands. I was talking specifically about the KA's stock piston ringlands. And I'm not really looking to get into a pissing match. I'm just letting OP know that turboing his stock KA is not a bad idea at all if done correctly.
