my friend the other day was saying that he had read an article where they speculated that an s2000 head may fit... can anyone else elaborate on this???

 

yeah i saw that article on club rsx and on that tov video it said in theory you could do it. However the s2000 is rwd and the rsx fwd that could be a problem i think, but i'm sure as time passes somebody will do it

 

how would being FF or FR affect whether or not a cylinder head would work on an engine...

 

as long as the head mounts to the block , then it will work....BUT ...the S2k does not use I-vtec ....and utilizes a timing belt , unlike the rsx which uses a timing chain ....so i doubt it will work

 

actually the s2000 uses a timing chain also.

 

no...i dont think it does

 

actualy it does i have built an s2000 motor from the ground up and it uses a timing chain!!

 

yup, it does. chris is right.

since posts from ppl never seem to be good enough, heres some proof.

http://www.autoweb.com.au/section_6/...cars/info.html

kinda funny that every knowledgeable poster needs someone or thing to back him up, yet the ones who dont know their *** from elbow are gods.

 

i also dont understand the advantages of putting an s2000 head on an rsx. yes it is a fact that the s2 head flows better then the rsx type s head, but it is also a fast that the type r head flows better then both. so why would you want to bother putting the s2 head on your rsx and not the type r head?

thanks for the proof LEO

really ...well now i know

 

the seeming advantage would be that it can rev to 9 k ....the valvetrain can at least..but the bottom end of a Rsx cannot ....with negates any gains...and eeven if you did rev it to 9k ....we dont even know if it will even have a powerband at that Rpm ...?

 

you are gonna spend all of that money to put an s2 head on your car just so you can use the stock valvetrain and rev to 9k, when you can probably spend 1/4 the amount of money that would cost you and buy a sick a$$ valvetrain and have the head ported and rev to 9k.and probably make more power then the s2 head. just a thought on why you would waste your time and money.

 

very true...even though you'd need to build up the bottom end to handle 9k...its not just the valvetrain

 

I'm really interested in this, if the F20C has a head that works on a K20A1(or A2) motor, what's stopping K20A2 heads from being retrofitted onto F20C's... or something of the sort?

 

actually now that you brng that up i, did some research awhile back and you can bolt an s2 head on the h22 block, you just have to figure out how to make the timing chain work. but the head studs are the same exact pattern. i dont think anyone else has tried it yet, but remember who told you that first. because someday its gonna be done.i physically bolted the s2 head to the h22 block and it fits,there are some coolant and oil passages that have to be directed a little one way or another but with the way that golden eagle does there deck plates. i have no doubt in my mind that they can make something work. like i said the only other problem i came across was the fact of the timing chain clearence with side of the block but anything can be done, you just have to figure it out. im currently workin on it now. but now that the rsx head also carries over the same head stud pattern there is a whole new head to be played with. i will have to try that soon. and do you think HONDA knows about this. i think they do, they are just waiting for someone to figure it out. and thats what im tryin to do.

and TSUNAMI i was just replying to your post about bolting on the s2 head and reving 9k. of course you will have to build the bottom end. it is not cost worthy when the type s head flows very similar to the s2's characteristics. but as far as putting an s2 head or type s or even type r head on an h22 that would be worth it. h22's are cheap. the heads dont flow anywhere close to the s2 or the type r and you can probably build the whole motor for the same price you are gonna pay for a type r swap $8500. whos got that cash just layin around, i wish i did. im gonna figure out how to do this i will keep you all posted on my findings.

does the F20c head have a significant larger amount of flow over the K20 ...or would a simple P&P ....port matching , ETC yeild the same results

 

the flow characteristics on the s2 and the tye s head are very similar, but the s2 head flows alittle better, but........ the type r head flows better then both of them. i was talkin to a tech over at toda and we were talkin about heads becuase i was gonna use the type s for my race car, and he told me that they have type s heads p&p'd that still dont flow as good as the type r. he said no matter what they do they cant get that head to flow better then a type r.if you would like to see flow charts check out this....http://alaniztechnologies.com/rsxf20c1flowcahrt.html

it does flow slighty better....so does the JDM Type R utilize a differant head than the Type S

 

id like to see flow charts of s2k v itr now..
id imagine rsx and s2k would be better than the itr, since there is less of an angle to vertical that the valve sits at as compared to the b series..

id still say use the rsx head. more direct flow since you can throw itb's on it and have em stick straight out from the hood. more of a ram air effect..

 

well when i say type r head i mean the new type r head. im sorry about that i should have made it more clear. but as far as the the type r head and the type s head being different im not 100% sure but the tech over at toda told me that it is the same kind of setup the si and old type r. and as far as the individuals sticking out the front of the hood that is what i want, a dirrect ram air into them. but if i put the s2 or rsx head on it will have to sit the same way as the h22 head.with the intake in the back.

you plan on running ITB's ...on a daily driven car ?

 

well this car is not gonna be daily driven it will be my race car, but to answer your question i already do run itb's on my daily driven car. i do not see a problem running them everyday.

 

really now ...ITB's carry no type of air filter element.....thus ...yes it sucks a lot of air ....but dirty air....i hope you change your spark plugs often ....

 

where do you come up with this?
outside of racing apps, itb's dont have to be run open to the elements.. there are airboxes and filters made for them..

before you doubt this, let me find proof..
