good info...I was always curious about this engines when they came out, but never knew anything about them.

So my first question is: what can be done to the k24 to get the rev's up?

 

[thedon365]

is there a k20a3 as well, im sure i've seen posts with this engine code mentioned. (or maybe i'm just a fool)

shorten the stroke and increase the bore

shorten the stroke and increase the bore

What about valve springs?

TODA makes all kinds of parts...

you need cams that support power higher then the current factory redline to facilitate the need for those my friend 8)

thats why increasing the bore is detrimental

increasing the bore also results in lower rpms?

no, the R/S is not affected by a larger bore, increasing the bore and shortening the stroke would allow the engine to rev higher and still have the displacement that you want
