it is possible in theory to use a F22c crank to destroke the motor to approximately 2.2L some modifications need to be made to the crank & to my knowledge NO ONE has done this (& if they have - it hasn't worked)

some aftermarket companies say they offer built destroke K24 blocks - but once again I have NEVER seen proof of a working motor.

I heard from a well know drag racer that the f22c crank in a k24 motor has created MAJOR reliability issues.

it could be possible to use a f20c crank but you would basically be destroking the motor to 2.0 L (i believe I posted this info in another thread - already)

The major downside to the K24 motor is piston speed not so much the R/S (which has an effect on the piston speed) custom rod (lengths) are also an option to decrease piston speed...

I do know of one person who has a completely built k24/k20 frankenstein motor - details will be provided soon (next month or so) I don't know if its destroked or not....but power (whp) is going to be BIG...don't expect the motor to last too long

thanks for the info. why wouldnt it last long if its built? im not planning on revving all high in my k24/k20 once is done. im not even planning on modding it much, just bolts ons and transmission work. i want to make a quick daily driver.
