ok we all know that lots of h23 and f22 parts will swap over to the h22.

I'm wondering about using things such as the 2.2L s2000 crank and other similarily displaced engines.

If anyone happens to know the crank dimensions (mains, rod journals..etc) for any engine that has similar displacement, post it up. I'm curious to see which cranks from other manufacturers such as Ford, chrysler, GM, Dodge...etc could physically fit in our motors.

Why am i making this thread? Who knows. Seemed like an interesting idea at the time so any of you who arent going to contribute to this thread, please just dont post.

DSM 2gen. manifold to H23/F22

Well this is within the manufacturer....but according to jdogg a k series crank will fit the h block with some modification to the snout

good thread

or was it the other way around? guess it doesnt really matter. If it fits in one block, it should fit in the other. But putting a k20 crank in an h22 with its 86mm stroke would be destroking the motor slightly. I wonder if there is any difference in weight.

regarding putting the h22 crank and rods in a K20 block

F__c cranks can fit modification to the snout. The bore and stroke of the F22c are identical to the H22.

do you know the size of the mains and rod journals?

Both exhaust manifolds from either 1st or 2nd gens will work; 4G63, they're the same.

1st gen = 14b turbo
2nd gen = T25mall turbo

the manifolds are different



the 1g ports are quite a bit larger.


anyway, how bout a k24 crank

...^that looks like an intake manifold

98vtec

wow....i'm an ***

i'll see if the exhaust ports are any different.

exactly, but the point was to use a k24 crank I believe....

98vtec

well i did a little searching and found that the k24 has a 99mm stroke in which case would require a deck plate or custom length rods to keep the piston from destroying the head.

i wonder if you could run that crank if you offset bore the cylinders? I dont know enough about that boring process to come up with an answer.

This sounds delicious...

https://honda-tech.com/zerothread?id=1294644

In that thread a seemengly informed fellow says the 55mm mains on the H series cranks are larger than the the F22C's mains. My bet would be that the F22C has 50mm mains. However that guy wasn't entirely wrong or right in his overall statement...

Beyond that, both the F22C and H22 have a a 90.7stroke x 87bore combo going. Now I'd like to know if anyone makes after market F20b rods...I believe they are longer than H22 rods @ 5.709 inches(?). Their pin bore remains unknow in the FAQ's.

I believe the bore centers are the same, are they not? Custom length rods would definitely be necessary....do you want me to explain offset boring?

98vtec

his reasoning going with the f22c crank was more determinant on things other than stroke and main journal sizing. ie: crank pulley thread pitch...etc

i think he meant F series when he mentioned the 95mm crank because thats the only h/f with that stroke, but the f22 has 50mm mains and there is no way the f22c is smaller than that. I think he possibly just got the two confused.

so i guess with the f22c crank, you would have to use the k series or f22c crank pulley

i dont know if they are or not, this is the first time i have done indepth research on a motor other than the h/f series.


and yes, please do.

LOL! We could refer to the 25 page H vs. K thread That I belive specifies the K bore center in it somewhere.

117

If the bore centers are the same, why would you worry about offset boring?? That doesn't make sense to me. If you have to offet bore the engine to fit a K series crank, why not just get a custom crank made, it'll probably work out to the same cost after all the block mods, eh?

bluedlude

i always wanted to know what the biggest crank you could fit into an unmodified H22 block would be. i dont know if its possible to get the F23 crank to fit in the H22 block?? youd end up needing either custom rodsand use H22 pistons, or use the crank and rods for the F23 and get some higher compression pistons. has anyone put an F23 crank into their H22?

somehow pocketrocketsracing fits a 100mm crank into the H22 with that offset boring, which i still dont totally understand, so it might be possible

98vtec

you could fit the f23 in the 98-01 blocks since the mains are both 55mm, the problem is the 97mm's of stroke along with the rods being roughly the same length as the f22 rods. I know that with the f22 crank, h22 rods and pistons, the pistons protrude from the deck by what...??? .020 something like that. Add another 2mm of stroke to that and you're likely to run into some issues LOL.

117

The stroke of the crank installed in the engine has nothing to do with offset boring the block.

offset boring = ..........???

How does the process of offset boring go?

bluedlude

if you used F23 crank and rods and H22 pistons it would protrude .038 inches. but like i said, if you used the F23 bottom end (crank rods pistons) then you would be at stock spec of 0.02 inches under the deck. youd need a custom 87mm piston to fit the H22 block w/ the F23 compression height and get a 2.33L.

well im aware of that, i guess my question is, why offset bore if you dont have to?
