h23 cant be 5speed as well....

umm i think the f22b came in the accord sir, if this is true then yeah it should fit.

i thought the f22b came in the JDM Si?

I think the f22b is a SOHC VTEC from the Type R Accord. F-series engines (I think) are only SOHC's, correct me if I am wrong. There is an H23 VTEC that Honda Made, I think it came from an Accord wagon or something.

its an accord engine its vtech the heads are identical from f22a and f22b you can acutally do a head swap, from what i understand it has a little more hp then the f22a but im not sure about the direct swap possabilities but it seems ot me it would work fine, realize you'll need the vtech ecu... id reccomend just doing the h23 swap if money is a concern because its probally teh same price as a f22a or b, take care peace.

Someone's first post! Welcome. Oh yeah, it's VTEC not VTECH

nkayhoe · 03-27-2002, 05:48 PM

thanks, my mind is going.

Jordan_4WS · 03-27-2002, 06:34 PM

I am almost postive..

USDM F22b = sohc 2.2 in accord
JDM F22b = Dohc 2.2 found in JDM prelude Si and maybe soem accords.

i thought the sohc vtec accords were f20

i dont know, im confused now

Whoa!! where in Canada are you? I'm pulling my old motor (F22) to swap in a H22A this weekend! If you need an inexpensive motor, I could sell you this one!! It has 127,000 KM and runs fantastic, I can verify the mileage and running cond, because it's still in the car (until tonight, that is!) Let me know ... depending on where you are, I could deliver it and save you some money..

Here's some info..

F20B = DOHC VTEC (destroked H22a, 200horse) JDM Accord SIr
F22A = SOHC non VTEC Accord/Prelude
F22B = SOHC VTEC Accord
H23A = DOHC non VTEC (5speed or auto) Prelude
H22A = DOHC VTEC Prelude

Guys, I just got a F22B. It IS a DOHC Non-VTEC 2.2L from the Japanese Prelude Si/Sr. The horsepower peaks at 6k and it's a hell of alot more torquey all around. I like it. Hell, I get 37 mpg on the interstate. You can use the same tranny/ecu. I just don't know what the compression ratio is.

160 hp @ 6k
148 lb/ft @ 5k?

teaguy · 03-29-2002, 02:43 PM

I have a f22b also and jsmooney is right. But do you know where i could find parts for this motor?

pter · 03-29-2002, 03:18 PM

More torquey than a H23?

jsmooney · 03-29-2002, 10:17 PM

thanks, teaguy. it seemed to me like no one would believe me. But, the f22 is more torquey all around in my opinion. It's also lighter. but, you can tell the slight torque difference. i went to this high-performance shop and they said that there would be no prob finding parts. I am guessing maybe parts for the F22A??

phildeez · 03-30-2002, 08:27 PM

I have the same motor. the parts would be the same as the usdm h23. the compression ratio is 9.0:1 Im pretty sure.
yes, it came in the jdm prelude si.

jsmooney · 03-30-2002, 08:40 PM

Yo, wouldn't the compression ratio have to be more since it has the same hp as the h23? It's a smaller engine too!

-JMoney

phildeez · 03-30-2002, 08:56 PM

the compression ratio is 9.5:1
the F22b doesn't have as much hp as the H23 it is less im not sure tho

you can check this site out

isn't the engine code on a S2K F20?

phildeez · 03-31-2002, 01:51 PM

I think the f20c is the s2k engine code.
