Would make a nice sticky...

bluetintruben

Okay this may be a dumb question but I need to kill any doubt for a friend.

Does an H22 head fit an F22 BLOCK.

I say no. She doesnt believe me. Help me fellas!

XiOus271

search. the short answer is yes it does, this has been covered a million times.

bluetintruben

Damn so it does? I've never seen it done before. Is it a straight bolt up or what?

like stated above, search. Or better yet, go into the FAQ and under the Swaps section you'll see some links to it. Lots of info on that swap out there.

Bummp for some great info

hondaccord

I thought it would be good in the accord faq too, but George Knighton said to just post it up. so I guess I just did what I was told to do. and as far as the h/f swap as far as I've seen the h23 head is easier to swap on then the h22.

right, we don't post the info straight into the FAQ. the user makes a thread for the info, then we link that thread into the FAQ

hondaccord

cool wasn't sure how that worked but good to know.

S-spec

There is a mistake in that list.

The piston volume for the F23's are not all the same.

The F23A1/A4 are -13.6. The F23A5 has a piston volume of -18.

Just a heads up.

Andryzzle

I wish i knew how to use all that info....

BIG T

are any F-series motors FRM

street_accord94

just the f20c/f22c found in the s2k uses frm

BIG T

see i thought that F22B's were cast iron sleeves factory

not cast, but iron yes

Another heads-up, the f22b2 intake valve is actually 32mm.

Hello,

i have a new used f20b dohc i need to overhaul the engine.
im a newbie not much knowing some parts of the engine..
planning to buy the overhauling kit and i head that h22a can be use
for f20b and how about the piston rings, crankshaft main bearing
and the connecting rod? i don't see many parts of f20b so i might thinking
that the h22a can be fit for f20b?

hope i can hear some good responds in the group.

THanks.
