Thanks man! I'm looking to swap in a k24a2 from a acura tsx. It will be stock going in until I figure out the tuning and stuff, then all the fast parts will go on. I promise I'll bring a touch of mazda to the honda engine to please the rotary gods🤣🤣🤣
Mmmhhh...to please the rotary gods you need a K20 engine and fit it for 9,500 rpm :D.

I wouldn't do that with the stock small block of the K24 nor the K20. But a proper built K20 manages that and if valvetrain is adapted for it, also above. The background, you may know that, is the piston accelerations will increase that much that piston-liner-clearance, main bearing and rod bearing clearances need as well as the weights to be adapted to that requirement. We talk about bolt forces of 2+ tons on each rod bolt when a 99 stroke block revs to 9400 rpm.

Anyway, I am looking forward to see that heart plant documented here. I hope you don't get issues with Valve cover to engine hood clearance.
