Anyone stroked an f22a?

[psyphre]

I know there's stroked H22's (2point6), but has anyone done a big dirty sohc?

You stroke it the same way as the h22. You can either call crower and order there h22 stroker kit or do it the cheaper way and just find a h23 crank with your choice of pistons and rods. Just remember to order h23 pistons and rods.

I'm confused. The tech thread says the storke is the same between the h23a1 and f22a; the h23 just has a bigger bore. Cause i have an h23a1 kickin around so that would be really convenient.

that's what I thought. And even if you did use the h23 crank, rods wouldn't matter, h23/f22 are the same, and why would you use h23 pistons? they wouldn't fit in there comfortably, you would use f22 pistons...

[psyphre]

i don't even think the pistons would fit at all, f22a bore is 85mm, h23 is 87mm.

EDIT: i looked at the crower stroker kits, or should i say the crower "bore the hell out of the motor" stroker kits.

h23 has more stroke as well. If you try to put a h23 crank into the h22 you have to remove the oil squirters at the bottom of the motor due to the stroke being bigger.

STROKE
H22A = 90.7mm/3.570
H22A1 = 90.7mm/3.570
H22A4 = 90.7mm/3.570
H23A = 95mm/3.740
H23A1 = 95mm/3.740
F20A = 88mm/3.464
F20B = 88mm/3.464
F22A = 95mm/3.740
F22B = 95mm/3.740
F22B1 = 95mm/3.740
F22B2 = 95mm/3.740
F23A = 97mm/3.818

Taken from the sticky at the top of this forum.

But he's not trying to stroke a h22, he's trying to stroke a f22.

[psyphre]

right, so i am gonna have to get the F23 crank.

[fast93accord]

The F22a and H23 crank are identical part #s from honda... I believe the F23 crank will not work due to a different journal size. Our motors have a huge stroke already... if you sleeve it you can bore to 92mm i believe, on a n/a setup and i think 89 or 90mm on a boosted setup(according to darton)

hmmm, that's what someone else brought to my attention earlier tonight. weird thing is i know for a fact that a local engine builder stuffed an f23 crank into an h22 or h23 block. guess i'm off to see the wizard.
