I just did a search on this and was suprised to find nothing. Anyways, what are the differences between the F22 and the F23? Post up as many as you know. This might make a good sticky if it can stay on topic

 

Well the 22 is 2.2 liters and the 23 is...no one saw this coming...2.3 liters. Also the 23 makes 5 more hp. Are we talking about f22a/b f23a/b? Give us more info.

 

the f23's are found in newer accords for a bump in power for the 4 banger .

Since 94 the ex models have come with sohc vtec and I believe the f23's started in 98 with the 6th gen. It is just a .1 L bigger instead of a 2.2L it is a 2.3L.

 

And now in 2003 with the 2.4 liter, .1 liter more for 7th gen.

Correct...I just wish honda would put a h22 in the damn accord and stop toying with us .

 

Totally, i bet they have one in JAPAN Accord. Where are you in Sacramento VRdrvr I was stationed at BEALE , AFB in 1975 to 1978 Marysville , Yuba City, California . I bought my first Honda there in Sacramento at the Pontiac dealer brand new 1976 Civic CVCC 5 spd $3,200.00, NICE PLACE SACRAMENTO.

 

hmmmm...i live in sacramento...maybe you got vrdrvr confused with me? well, in either case, i live in the folsom area.(yes, where the prison is =P)

 

yea but where does the extra 100cc of displacement come from. (bigger boar?? Longer stroke???)

 

good question. Main reason I'm asking, is what differences would there be that could influence the exhaust bolt pattern. As far as I knew, the only difference was in age, and the slight hp diff

according to, "accordingly.com", the bore on the f22 is 85mm, and the stroke is 95mm. on the f23, the bore is 86mm and the stroke is 97mm.

 

bigger boar...lmao sorry that was funny...boar...thats like a piggie wiggie

 

If you're talking about the F22B1 compared to the F23A1, here are some of the major differences:

.1 Liters more displacement - caused by bigger bore & stroke
The F22B1 is 85b-95s the F23A1 is 86b-97s.

The F23A1 also has a knock sensor incorporated into the block.

The F23A1 intake manifold is a bit different, for the good (better flowing). But, the intake ports and exhaust ports are the same for F23A1 & F22B1, because the heads are the same; except that the F23A1 head has a VTEC oil pressure switch, whereas the F22B1 does not.

The stock exhaust manifolds (I know, not REALLY part of the motor), are different also. The F22B1 uses a 4-2-1 (tri-y) design, and the F23A1 uses a 4-1, short primary design.

The F22B1 has a compression ratio of 8.8:1 & the F23A1 has a compression ratio of 9.3:1.

F22B1 = 145hp & 147lbs/ft
F23A1 = 150hp & 152lbs/ft

The F22B1 is either OBD1 or OBD2a, depending on year model.
The F23A1 is OBD2b.

That's pretty much the only differences in the engines, as they are stock.

 

good info, thanks for the helpful post

So you think the IM can be interchangible for the f22b/f23a? Same with the header? And both gaskets? This can be good for 5th genners... swapping to a f23a IM instead of forking out money for an IM port and polish.

 

"except that the F23A1 head has a VTEC oil pressure switch, whereas the F22B1 does not."


Would this matter if I was to use a cam from the F22B1 in my F23 (could I do this?)
Talking aftermarket here of course.

Yes, both manifolds and gaskets are interchangable. Just use the gasket that goes with the manifold you are using.

Nope.

 

Does anyone know if the f22 or the f23 has oil squirters?

 

I thought it had somethign to do with the bore and and the stroke.

You guys proved my assumption correct.

 

What are the rod lengths?

 

yeah whats the r/s on both moters

hmmm, what cars have that there F22B1?? (im tryin to get ghetto header's here) and will it line up on the block and under the car for 6th gen accords, or is that too much for the honda gods to bless us with

I'm guessing thats your question? Even though you had it apart of carolinaACCORD's quote, I can't find it anywhere else in the thread. So...

The F22B1 came in the 94-97 Accord EX. Has to be EX, the94-97 LX and DX had the F22B2 which I believe used the 4-1 design exhaust manifold.

 

[QUOTE=First Honda 1976]Totally, i bet they have one in JAPAN Accord.

They do!..Unfortunately not in the US!

 

What up everybody

so I’ve been reading up on the threads and even here in the future information is scarce

but what turbo can be put onto a f22b1 motor and how and where would I add a oil line that goes to the turbo

i have a 97 accord exr with 187k

i recently bought one to learn stick and it has a decent rod knock that I’m going to have to probably tear down and get to

i found a nice 11 part vid from ktec garage on YouTube but that is a f23 engine which for the most part sounds like a slightly bigger f22

and hopefully when I get into it, it will be like it as well as far as procedure tear down goes

any insight would be awesome

ps

also found a video so I’m wondering if this is comparable to what I’m going to want to be doing

Check out the FAQ at the top of the page, there were a couple of threads on Turbo F22s.
Ash had a nice setup, think he used 4G63 pistons and modified header IIRC.
