hey guys,
rumor has it the f20c crank will work in a k24 block to slightly destroke it, improving the r/s ratio, rod angle & length, lowering piston speeds, safely raising the redline, and ultimately making a more reliable hybrid engine.

so my question is THEORETICALLY, since that would work, let's try the opposite: would a f22c crank work in a k20a block to increase displacement??

i know there would be a difference:
f20c crank in k24= roughly 2.3L
f22c crank in k20= roughly 2.2L

question is, which motor would be more reliable & have better output??

now i know the k20a block is a perfect square (86mm stroke x 86mm bore) leading to an almost perfect balance between torque and power/revving, so hopefully by increasing displacement would it have more torque and more power also.

feel free to weigh in w/ your opinions, but try to keep it on topic
(i'm a noob when it comes to calculating compression #'s, ratios, and all that ish, so please don't ask me to prove it)

 

don't think so b/c k24 block is 19.7mm higher than k20a...without that height i think you will have some major piston - valve contact (although i could be wrong)

and that s2000 crank you talk about (to destroke the k24) is out of the 2.2L '04 s2000 f22c not the f20c

edit - i think if you did stroke a k20a block you could easily ruin the reliability of the motor & the capability to rev to 8000+ all day

BTW - PLEASE NOTE I heard you can run into problems just dropping in a 04 s2k crank in a k24 block...issues with it not fitting perfectly (if it can be done how come nobody has done it with success.....yet)

Ron at IPS is working on it as we speak.
