i have a DC header on my 91 'cord f22a1 ...that should directly bolt up to the h22 right? thanks

 

they are different.

 

can i get more info about being different... do u mean it absolutely wont work???

 

First off you should have done a search because this is asked over and over again but no big deal. To answer your question they are a different bolt patter, the F22 looks like this, o o o o The H22 like this: o oo o when comparing the two and unfortunatly it won't work at all.

 

correct

 

man that sucks...thanks for the input though!

Other way around

 

actually hes right. the f22a's are evenly spaced, the f22b's had the inner ports all scrunched.

actually your wrong, if you had read TOABs post you would know that f22a - o o o o and f22b o oo o and h22 - o o o o dont flame unless you have your facts striaght, if you want further proof of teh f22 differences ill go down to where my 94 is stored and take the heat shield off take a pic, and take the heatshield off my 90 and take a pic and show you the difference. actually your only half wrong, the h22 pattern on the second post is wrong but the f22 is right if they are speaking iof the f22a

 

this is such a popular topic, it should have its own forum.

 

i edited mine. i can speak on behalf of the h22a and the f22b cuz i've tried them both and those do not work. as for the f22a i cannot yet speak for.

first off, i have both motors, f22b and h22a, 1 sitting around and 1 in my car. even if the f22a is o o o o, it wont fit on a h22 head anyways.

 

why is that, the spacing is the same, the only thing i can think of that would make it not fit is an incorrect bolt pattern.

 

Can the lower portion of the F22B1 (VTEC) Header be used on the Top portion of the JDM H22 Header?
I would think so since they are both 4-2-1?

TIA

 

but the lower portion of the 2 piece H22 header is just as good if not better

 

Let me rephrase that: Can the lower portion of the F22B1 (VTEC) Header be used WITH the Top portion of the JDM H22 Header?
I would think so since they are both 4-2-1?

Thanks

 

it might... i think the diameter on the h half would be a bit bigger... so maybe they wont line up quite right.

and for the spacing crap earlier, F22A's have evenly spaced ports... the F22Bx's have the scrunched center ones. if all f22'a were o oo o 4th gen people wouldnt be able to use 1g eclipse turbo manifolds.

 

No it won't work I tried it the H22 is bigger than teh F22

 

isnt that the point of getting aheader in the first place?is the flange bigger??? please elaborate
