Need some advice

[flcb7]

ok I got my hands on a h22. Long story short block is toast except for the crank head is still good. My idea was to use the h22 crank ( if it can even be done. dont see why not since ppl put the f22 crank in h22s all the time ) into the f22 block (id use the f22 crank but it spun rod bearing ) Use f22 rods and pistons.
I know I will be dropping the C/R when I put the h22 head on the f block. But now since I will be using a h22 crank am I dropping the C/R even more since the h crank has less stroke??

plz tell me is there are any flaws in what Im trying to accomplish. Thanx in advance.

What year H22 is it? There are two different size crank main journals. In a perfect world you would want the 50mm crank.

92-96 H22A1 = 50mm
97- H22A4 = 50mm
98-02 H22A4 = 55mm

If you have the 98+ 55mm. You could machine the main crank journals down to 50mm (± spec bearing clearances)

Other than making sure your crank journals are the same diameter. & your OK with the following;
Compression ratio - 7:1
Rod/stroke - 1.56:1
Displacement - 2058cc
I don't see any problems with the build technically. Your pretty much going to end up with an very low compression F20B. Boosting this thing will be your only salvation.

its a h22a4 so its got the 55mm but Im trying to stay away from machining if I can. an yes it will be boosted or can I use high compression pistons to make up for the low compression

wont fit and the piston will be too far in the hole.

what wont fit??

You don't want 7.1 compression, even boosted...

You don't want 7.1 compression, even boosted...

so then what are my choices at this point?? Can I go with custom pistons to raise up my C/R and not boost stick n/a??

I guess I might just machine the f22 crank and the rod that has the spun rod bearing...Id be better off wouldnt I??

[wed3k]

you can do that but why dont you just get another h22 block? do it right.

I dont have the cash for another h22 block. plus hear in Tallahassee ppl are h22 GREEDY as fuck. Id never find one @ a good price. Or a the pnp or jy. cus the day a h series or k series hits the lot they guys @ the jy an pnp already have called there boys and they are gone with in hrs. plus I already have a f22 block and a h22 head so why not just go from there you know what I mean.
The motor will not be placed in my DD cb7 it will be swapped in a civic for a "fun" "race" "weekend" car. I mean I have a h22a4 block but Im sure its fucked...it was hydro locked like a mofo. One of the rods are bent into a U shape almost. But the head and crank are fine...I guess I could have someone else look @ the block to see if it is still good. Im just dont have the money to drop into 4 new sleeves. so Im stuck @ this point...

[flcb7]

Iv been doing ALOT of thinking...Im gonna try to find me a h series block and ditch that f22 block...like you said why not do it right...and thats what Im gonna do. Thanx everyone for the help.

[wed3k]

or just get a f22 crank?

[Accrdwgnguy]

Doesn't an F23 crank have 55mm mains

[flcb7]

well come to find out Im gonna be able to use my h22a4 block. Soooooo Im gonna still use the h22a4 crank (55mm) b/c my f22 crank had a spun rod bearing. So instead of machining the f crank I think Im gonna just use the a4 crank since its good to go....I think???
