On the contrary, it has been my experience that motors that have a larger stroke than bore ratio tend to resist revving. And while this may be only one factor in the grand scheme, destroking -- IN ADDITION TO grinding/balancing the crank, swapping in a lightweight flywheel, a good port and polish job on the head (which I did forget to mention in my pricing) and performance cams are certainly going to aid the motor in increasing redline. And as I said, it's not going to rev out to 11000rpms before redline like a B16, but a 7500rpm redline is NOT unrealistic for the aforementioned setup. Simply put shorter stroke = less friction = higher potential internal speed. If you would like to disagree I have several college text books and ASE certifications that say otherwise. Longer stroke = more friction = lower max RPM. Especially when stroke is a greater than value bore. (Directly from "Hot Rod U, UTI Glendale, AZ). Now while I'm not disagreeing with you, yes the valvetrain does have a lot to do with how an engine breathes, as a DOHC 16v engine, with the KA24DE the stroke to bore ratio plays a much larger role, as does the head, as does the crank and the flywheel.
A well ported/polished and balanced head, cams designed for turbo applications, a ground and balanced crank, shortened piston rods and a lightweight flywheel should be good for well over 1000 more potential RPM which is not an unreasonable number to expect. I didn't say it would redline at 12,000 rpms, I said 7500. My cavalier revs higher than that and it's bone stock...
But anyways, take it or leave it... I fully believe that given this setup the
KA24DE is more than capable of producing HP figures in the 300+ range. Plenty of people have for less money.
