I believe it is a little bit of both. It's a custom cylinder block. Pretty much the only OEM Kawasaki parts are the head castings, throttle bodies, and a few other things.

They designed these particular billet blocks to bolt right up to the OEM transmission. They can modify the design to bolt up to anything they want.

At minimal, I feel like heat buildup could be an issue.
Yes. The OEM transmission's synchros can't keep up at those high RPMs, so shifting will be difficult. If you watch the JUN shakedown video, the driver shifts very slowly. Heat is definitely an issue, so I run a transmission cooler for the Quaife.

Sorry for the threadjack!
