if my thought are correct, a BC h22 stroker crank (bc5039) 55mm main and 100mm stroke in a F block line bored to 55mm with a longer rod should produce a longer stroke over stock, my question is should i flush this thought down the toilet or is it possible to pull this off after you clerance the block so everything rotates free? would i have to get some custom pistons made with lower wrist pens to keep the pistons in the cylinder and out of the head? thanks all

 

well i take it my thought needs a one way route to the land fill

 

you would need shorter rods to work with a longer stroke crank. The F23A1 bottom end uses 55mm mains, 97mm stroke and an 86mm bore. it's already a half step in the direction of what you're talking about doing. any F-series or H-series head (F20C excluded) will bolt on. just a thought..

 

ok so you are saying the dohc s2k head will bolt up to my f22 block? one is belt and the other is chain drivin timing correct?

 

the rotation on the two are different an s2k comes with an f20 and an f22 but like i said its a reverse rotation from the other f-series, in which it would not work, why did they do this? I wish they hadn't, it would be awesome to use that.

 

that is why the guy said the f20c is excluded.

they did that because the f20/22 c engines are the transition from F/H series to K series.

 

There are stroker kits available for the F22...cost you $2500 + machine work & labour. I've looked into it, not worth it in a daily driver IMO. This is why I kept my 95mm stroke and went with longer rods, a shorter piston CH and 89mm bore.... 2.4L displacement without requiring a longer stroke. Equals out to a better rod to stroke ratio, if that means anything.

 

thanks ghost...it must have been you i talked to about using longer rods instead of a 100mm stroke crank? what is the length of rod you used to achieve a 2.4? thanks

 

143mm H22 rods. it's more the 89mm bore that gets it up to 2367cc = a Honda 2.4L...lol

 

ok so to get a 89mm bore ( which the stock sleeves cant handle) i would have to get a set of darton sleeves? correct me if im wrong please, would i have to use the same floating wrist pin style piston too?

 

Yes you will need sleeves, may be able to get away with using a set of dry sleeves. They are a bit cheaper to run. You would have to contact the piston manufacturer of your choice as to whether or not they can make you a set for press fit. I'm pretty sure Wiseco will make them ether way for you.

 

Dayummm wats the hp and torque numbers looking like on that 2.4. Vtec? Stock cams?

 

No numbers yet...still on the machine shop bench..... It's Non VTEC, SOHC with a custom camshaft.
