i been looking around i couldnt get any info

sooooo i want to build a ka24et with high rev for my 240. to do so i would need to mate the KA head to a L or Z series block with a Fully Counter Weight crank. to mate anything to the ka head i need to bore the Cylinders to at least 89mm.

I want to get at least 10k rpm safely

the questions is a) what do i need for pistons and rods (would the ka rod and piston work)b) which block and crank should i getc) how would timing workd) anyother mods i need to do in order for this to work

thanks in advance for any info(i am posting this in the ka24e/ka24de too)

if you want high rev's, why not just put an sr20 in? low end torque is what the ka is all about. not so much on the top end.

Holy bejesus, 10K?

What the hell for? I can't see any KA being effective at that ridiculous RPM.

Please sir, just give up on that idea. Its hard enough on an already high revving civic.
