I tried to search, and i found somone who said they had seen a f20c crank in an h23 block but nothing more was said after that. And i've seen people post since it spins backwords it wouldnt work (im on this side) ... But just curious as to what about the crank actually makes it rotate backwords? I didnt find a picture of the crank to compare to an H... Im just curious b/c i cant find any solid evidence either side is right? It'd be nice if we could put the f20c crank into the h22a to see what kind've power it can put down.

 

even if it did fit...I don't see the point in putting a tiny 85mm crank in an Hblock. The new s2000 has the same stroke as the H22a, 90.7..it's for a reason. Unless you like having no torque. The power from the s2000 is not because of the crank.

 

I was just curious, some people dont care about torque though

 

well torque is So important. when you learn that peak hp isnt everyhting, youll also learn that torque is acctualyl what makes the car move.
Thus why a H22a in a civic is so fast. Not peak hp, its torque.
oh well.
But satan, what about a f20b crank?? would you need to get longer rods also??

 

you would just use f20b rods.

 

yes, if u dont get longer rods u wont meet proper deck height and so you'd loose a lot of compression i would think... I know torque is a factor, but to much doesnt help a fwd car... **** there is traction issues as is. the f20b crank is a bitch to find, you'd probably have better luck finding an f20a and then just bringing it to a machine shop and get it werked

 

So according to you a Civic will be faster with a Suzuki Hayabusa motorcycle engine than the engine that's in the car.

 

no i didnt say that at all, whatever i could care less it was an idea... you guys can think what you want about me.. the way i see it torque isnt as needed on a road course as ability to rev, for the quarter mile yea torque is greatly needed but im not talking about moving from a stop

i think its a good idea, if you don't want alot of tourque then thats cool, your setup is yours.. i think that the F20c will only fit in a 98+ h22a4 because if my memory serves me correctly i think the f20c has 55mm crank journals just like most 98+ honda motors.

so i think it will work just fine. good luck


edit: if person X really did have the f20c crank in their h23 block, then perhaps it was an h23 that had a spun bearing and they bored out the mains to accept 55mm crank journals, as i am doing with an h23 so i can put a 98+ h22a4 crank in, but im saving the block. im pretty sure the f20c has 55mm crank journals

 

I'm not putting that crank in my car... i drive an accord i would like torque my car is heavy, i'd just like to see how a civic would do with it. I'm going to be doing an f20a crank for the motor im going to start building (probably wont be done for like a year 6 an hour blows, being young sucks)

whats the f20a have for a stroke?

 

the f20c crank would drop the displacement to 2.0, correct?

 

yup if the f20c was used, and the 87 mm bore kept, then you would have 1997cc just like the s2k.. but piston choice would be very difficult, as you will have to compensate for the differences in displacement, and head volume to accheive desired compression ratio

but if you used the f20c rods, it will still bring the pistons up to the deck. so that would mean if you used h22 pistons/head...it should have the normal compression.

 

true, but there may be a slight variation due to the h22 head cc chamber being slightly larger than the F20c, but i bet nothing major,

but no way in hell i would want to buy new f20c pistons and rings, they are SOOOO expensive, but frm compatable forged

 

is it really the same frm?

also there was a post on why you couldnt use those pistons in h block....

but there also was a post on why you couldnt put h head on f block...

you would prob have to dremal the valve pockets of the pistons...since there backwards compared.....and let me tell you after last night, ill never say that only takes 10 min. again

yes its the same FRM, and the post on not being able to use the f20 pistons in the h block was if you tried to used h22 crank and rods and the f20 pistons because the pin height of the f20c piston is different than the h22 so in order to reach proper deck height you would have to have the block decked a **** load to the point where it would not be ususable except for that specific combo of h22 crank rods, and f20c pistons.

as far as the valve pockets go, theres once simple solution, clay the motor to see what clearences your working with, and if you not comfortable or the valves hit then break out the dremel. i think the f20c cams though have a hihger lift and duration than the h22 but i could be wrong, clay is the way

Same as f20b, 88mm i found the dohc f20a for pretty cheap so i picked that up and am gonna make a lil hybrid out of that also just for kicks hehe. I'm curious as to what else can be swapped over from the f20c... f/h series are gonna be doing just as many crazy things as the b series motors i think hehe

 

so is there any difference between the f20b crank and the f20a? what car does the f20a come in, can i have one?

 

im assuming the f20b crank has been lightened and balanced and everything from the factory (i'm goign to have a machine shop work the crank to hell hehe). the dohc f20a that i got comes from the 90-93 accords, it shouldn't be to hard for u to find a whole f20a motor either sohc or dohc both have the crank, i chose the dohc one because i think it'll make a fun lil motor and i found it for 200 bucks haha. and then with the h23 crank and rods to stroke it out i think will be a good lil boost motor (swapping the f20a crank to the h23 block so goign to put the h23 stuff inside the f20a)

there are no f20a s in the usa right only EDM?&gt;? or is http://www.accordinlydone.com wrong?

 

No they arnt in the USA, i had purchased mine from a place in cali, shipping was a bitch but paid 200 for the motor itself... You can try and check a local importer, there was a sohc one for 300 around here that i was about to pick up till i saw the dohc one haha
