Hey... just looking for input here. I have a 94 H23A1 that is bad (haven't torn it down yet, but assuming bottom end dmg). I also have a 92 H22A1 that is a complete running engine. Is it possible to put the H23 DOHC head on the H22 SOHC to up compression and build horsepower? I know there is much debate about head clearance putting the H22 DOHC head on the H23, but I never hear of putting the H23 on an H22 block.

Yes I know this is an odd combo that most people would never do, but since I have both engines... why not. I put a D16Y8 w/ complete engine-dash harness in a CRX running OBDI because I had it all... I know about the challenge. I just want to know if the "H" head swap is physically possible, and other peoples thoughts on the raised compression and its affect on power.

PLEASE... do not post saying, "why don't you just go get a H22 DOHC and put in the car?" I AM NOT doing that, I am not spending the money. The entire point is to use what is available.

Hope to hear some good news from you guys... thanks in advance!

yes the "H" head swap is physically possible. neither H23 or the H22 are SOHC so I dont know where you got that from. But IMO I dont think this swap is going to do anything for you. Maybe the H22 head on the H23 block but not the other way around.

 

what is the engine code for the SOHC motor they put in 4th gens?

 

You are mistaken... the engine is a H22A1, and the SOHC non-vtecs ran from 92-95 for sure. This particular H22 is from a 1992. The H23 is from a 94. The SOHC really weren't that rare... just overlooked (for good reason) in our world of modification.

 

This is basically the same engines in the 90-93 Accord F22s... difference is head, intake manifold & horsepower. Certain year difference is crank sensor, oil pump assm, head, intake manifold & horsepower. So, this would be the same as putting an H23 head on a F22....

 

theres a SOHC H22? sure its not an F23 head on an H22 bottom end?

 

I am not a retard... I own a salvage yard and have been dealing in Honda parts for over 15 years. I am looking at the block, it is an H22A1... is it that hard for everyone to believe? Obviously, no body knows if you can put the H23 DOHC head on it if they don't know the engine exsists. Here's a better question:

Can you put a H23 non-VTEC DOHC head on a F22?

 

This is exactly what the ADP Hollander Interchange notes have to say:

Hollander Interchange Notes:
Honda 2156cc (2.2L, 4 cyl).
Programmed Multi Point Fuel Injection (PGM-FI).
SOHC.
16 valve.
FWD.
Change induction & electrical systems as necessary.
See notes to determine proper interchange.
C -----------
Ident: H22A1
Engine model H22A1.
135 H.P.
|A|, |B| & |D| fit; difference is head, intake manifold & horsepower. **This is F22A1, A6, & A4 respectively**
|E| fits; difference is crank sensor, oil pump assm, head & intake manifold.**This is a H22A1 for 96**

Any questions?

 

no, the question is, is it hard for you to believe that someone put a different head on an H block. just because the block says H22 doesnt mean the head is for an H. whats the code say above the exhaust ports on the head?

 

H22A1 is NOT a SOHC!
H23A1 is NOT a SOHC!
F22Ax is a SOHC!

 

I already answered your question! Yes it is physically possible to put an "H" head on an "F" block and vica versa!

 

If I said H23 SOHC I made the mistake (which from what I can tell, I never made that statement)... but there is a H22A1 SOHC... I just posted the interchange info to prove it.

I know you're "white" but that's no excuse for not being able to read! (yes, I am being sarcastic about your avatar! )

Here's the VIN from the car: JHMBA8147NC011720 check it yourself. IT IS A H22A1 SOHC. This is just like the ZCs, they made ZC DOHC Vtecs, the ZV DOHC non-vtecs, and the made ZC SOHC non-vtecs. Just because you're on Honda-tech and you haven't seen it, it doesn't mean it didn't exist!

I swear, Honda-tech is getting as bad as every other board with uniformed nay-sayers.

 

BA8 is the code for an S model prelude which has the F22A1 engine.

H22/H23 are both DOHCs! Sorry to bust your bubble!

period the end.

 

Trust me, you're not bursting my bubble because I am correct. I am sorry you can't read the facts (I am being serious this time). If you are so convinced, you need to come to KY and I will show you. I also have the F22A6, a F22B1 and whatever else for comparision as well as a large selection of other Honda engines. Plus, this is not the first SOHC H22 I have seen.

I have 15 years of experience with Hondas and parts in general (including owning a salvage yard), what makes you the Honda God?

Bluedlude... when I get a chance, I'll climb up and see what that head marking is for you.

As for the rest of this post; it is apparently useless, nobody wants to help answer my question, everyone just wants to show their stupidity... THANKS HONDA-TECH!

 

As for the answer, I did get the yes from you white... but I am unsure if you know what you are talking about.

 

Also, I know you can physically put the H22 DOHC on the H23, but there are problems with head/piston clearance that make it next to impossible to do correctly without changing the rotating assy. This is the USEFUL info I need, I know the H and F blocks are similar and bolts will work; what is needed for the swap. Since nobody believes the engine exists, then nobody has done the swap, and nobody apparently can tell me of any issues to be of concern.

As for the F head on the H engine idea... this car was purchased locally from an older gentleman, it was not modded in anyway and even had an AT behind it. It was a factory SOHC as stated in the interchange notes. ADP does not get $600+ a month for their interchange info from 3600+ salvage yards if it is wrong.

 

if it really meant the much to me i would drive to where you are ( i do already live in KY ) and show you what is correct. but to be honest with you I am telling you the answers and you are refusing to believe me, which is cool.

You show me an H22 that is SOHC in which the head has no been swapped or NO modifications have been done then I will quit Honda-Tech and never log back on here to give "false information".

 

the code on the head is going to answer all your questions. its usually right above the #2 exhaust port. H and F head blocks trannies are totally interchangeable.

 

There is no such thing as an h series SOHC
Its probably a f22 head on an h22 block or something
You have the s model which came stock with the f22 so idk

HOLY ****, So I have been right the whole time!

w00t!

In all sanity, with me stating I have this one and I have stated that I have had them before in my shop, plus I showed you the interchanged info stating the VIN to have, which the car does... how can you be so sure of yourself. You don't work at a Honda engine plant. You are not a god or alien with all-knowing powers. Why can't you admit not that you were wrong, but instead that you learned something.

Working in cars, I learn things everyday. I have it, I have the documentation to back it up that it is correct. In my world, it exisits... and apparently in the real world...

Here's an add for a part... first thing I found on google (yes, I know its a light bulb), but look what it fits:

The list can go on... need any more proof?

 

all those post say there is no such thing, and its pretty much concluded that its got to be an F22, or F23.

Like most Honda Ricers... modify one and run a 14 and you think you are the Honda GOD!

You may not have seen one, but you are all stupid for thinking there isn't one and that you know everything.

None of us know everything about Honda's or anything for that matter... including me. You guys are showing your stupidity to the entire board. I have backed my claim up with info upon info... all you tards can do is say, DUHHHH Thars no sucha Thang!

Its really easy to prove something exists... its really hard to say with 100% confidence that it does not... because it just might (and did) appear.

I refuse to respond any further... if I haven't given enough proof, it wouldn't do any good to cram one up your butt! You still wouldn't admit you were wrong.

Honda-Tech is just as bad as any other board for someone who needs help with something that's not standard. If I, or anybody else, had listened to you guys, they would have been misinformed.

GTH

I'm done with this bunch.

 

you never got the code off the head. you can prove us all wrong and make WhiteBB2 leave forever

 

B-Kerr your wasting your time. I too have fallen victim to false information from seemingly reputable sites online. As stated for the millionth time, there is NO SOHC H22! Period end of story. All H22's in all markets are DOHC. Moreover there is NO such thing as a 92 H22 VTEC. This engine did not come in preludes until 93. (At least in the USDM market) So please stop, you are entirely wrong. Please go get yourself a helms manual, or look at any honda parts site and see for yourself.
