G22? I guess that's what it's called.

Anyways, I got half the swap done

I got a f22 block with a h23 head mounted in my lude as of now, but it's not as fast as I would like, and there's not enough aftermarket support for the h23. Therefore, I'm going slap a vtec head on it, get more power, and be able to upgrade more efficiently.

I've been like... 18 other prelude forums, and have came up short. no one has done the swap in detail. I've come across people that have done it, but never did a build thread on it, never said what has to be block off in the head, where the oil lines are ran or anything. And I know theres a sollinoid for vtec wiring, but I have no idea where lol. I've never owned anything with vtec, so i have almost no idea what's going on with it.
If anyone knows anyone that has done this, or has done this themselves, then can you point me into the right direction?

94H_Ex · 12-11-2008, 12:16 PM

Im right there with you guy. Im looking into the swap my self for my f22 block. Theres a certain year where the h22 head and the f22 block matches up. i think you only have to block off a water port or something in the f22 block. Im looking into this now. Its like... a Myth or something...

No kidding, eh?

Well, I'll help ya research it, too. So, I'm taking a wild guess that the F22 blocks are all the same? Whereas the h22 heads are slightly modified? lol, what luck lmao

Awesome, I got a f22a1? I believe. lol, I looked at the h22 heads, next to an f22 block, and there's not a whole lot of differences, like you said, maybe one water port, or oil port. Idk, anyways, hope we can help eachother out.

94H_Ex · 12-11-2008, 02:18 PM

From what I was told is that a certain year h22 head or h23 head. will bolt up. all you have to do is block something off, and get the h22 timing belt. being DOHC timing belts are bigger than SOHC belts. Im not sure if the h22 and f22 blocks are exact same. the f22 and h22 will interchange tranny's. as well as flywheels and clutches. Both are a bolt up into the accord and prelude. I'm thinking about just going ahead and getting the h22a engine. But I might have to pull off my f22 head and replace it soon or rebuild it, but if I find the DOHC head that fits and is decent. Then I'm going to be different for alittle while. This isnt going to be a permanent swap for myself.

calmfornow · 12-13-2008, 01:56 PM

well i think its the oil line that you have to run...not 100% sure where but yea...like it was said the trannys are fully interchangable...i would recomend the h22 tranny with the head because the h22a tranny has that tranny for a reason...the shorter gears will let you get faster accelleration but the f22 tranny will get you higher speeds...the vtec solenoid is right behind the distributor and the vtec pressure sensor is under the distributor the pressur sensor has two wires one to run to the ecu and another one is a ground and the solenoid is one wire that runs to the ecu....also i know with a full h22a swap there is a knock sensor on the engines, i think you might need a knock sensor for it also...its one wire that runs into the ecu, and you will need the h22 ecu out of a prelude or any vtec ecu that matches with your obd type.....all in all it is easier to just swap the h22 in, its easier in the long run and less headaches i did it to my 91 accord and i was thinking about just the head before but i looked into it, it is next to impossible to find litrature on this kind of project...so to make it easy just swap the whole engine, and also the compression might be a little wierd for it also, not 100% sure but i know the h22 is 11:1 compression and the f22 is 7:1 compression i bielive...good luck

or a better power situation is to stick with the full f22 engine and boost it...you will get more power and torque with a boosted f22 rather than a h22a swap

94H_Ex · 12-13-2008, 09:48 PM

Calmfornow.. your missing nearly the whole point. Im not looking for better power and what not. Its something that hasnt been fully recorded done. Im looking into it to find if its even possible. I know for a fact the h23 head will bolt to a f22 block

Exactly. I'm not looking for a full h22a motor. Way too much money. I'm looking just for the head and corresponding parts. Do it the poor man's way.

and when I get it all working, with full vtec, then ill be able to do a full write up on it, and help out others that would like to do this hybrid build. Cause it's impossible to find a write up on it. I've searched and searched. And apparently there's others out there that look for the same thing, but come up short. And that's why I'm here

capslock20 · 01-01-2009, 05:19 PM

well i have seen a f23 block and h22 vtec head you get about 248 hp and 181tq they call it a G23 it is sick!!

Bullshit. No way was that motor just a stock H22 head and F23 block...

94H_Ex · 01-07-2009, 01:49 PM

I ve read about it. he mated a H23 head on a f23 block I guess. as well he put K20 pistons in it believe. I dont remember seeing any pics but yeah, he calls it a G23. You have to block off some of the oil drain ports. I'll have to find the article.

je power · 01-08-2009, 09:04 AM

the g22 swap is a sick build. that can put out some power with a lil boost

94H_Ex · 01-08-2009, 03:48 PM

G22, isnt an actual reported swap yet. Its only a myth for now. No one has reported to put a h22 head on a f22 block yet. just the f23 with a h22 or h23 head.

now a h23 head can fit a f22 block.

btw, I think its f'cking stupid that instead of calling this the mini me f22 version. they call it G something.

capslock20 · 01-10-2009, 12:09 PM

then again i think if your the first to do that swap then you can call it whatever the hell you want why not?

Jackflat2100 · 02-19-2009, 01:08 PM

yes i very new to the honda engine game but im interested in this because i have a tight budget and i waisted a few hours on that honda-tech thread because almost 10 people waisted post trying to argue witch F22b block was ready for vtec when the first post in the thread said all you need to know about the differences

oksorry bout the rant had to get it out but from what i have been reading it should work the same as the h23/f22 swapso if someone would give me a simple list of parts needed and problems i might run into

Stleger184634 · 02-19-2009, 01:18 PM

its the g23** and here is a write up from a guy who did one 100% legit very nice write up and u can also find a second one on honda tech with dyno sheet from the same guy gl on swap

jammer008 · 02-19-2009, 02:01 PM

i have been reading a ton about these motors, i realize that you can put a h23a head on a f22a block. if i put the h23a head on the f22 block i wanna run a turbo. but i kinda want the dual overhead cams instead of just running the single.. so should i just get the h22a motor and then get a turbo?

Jackflat2100 · 02-19-2009, 08:38 PM

se my question keeps gettin skiped over i did type h22a and f22b all usdm like i said it sounds very doable but people keepand i sticking to the thread title F22block/h22 head because if it works all i need is a head and so other parts

jammer008 · 02-19-2009, 11:42 PM

can you do the h22a head on the f22a block? or does it have to be the f22b block?

Team Santizo h22accord · 02-24-2009, 12:10 AM

Hey my name is javier and i wanted to know if u know if you whats the block to use with the h22 head. I have the f22a1 f22b1 and the f22b2 idk which one to use.

Jackflat2100 · 02-25-2009, 06:53 PM

as far as i know about the f22b the 1 and 2 are the same block the number on this show vtec or not
b1 vtec
b2 non-vtec
id say do a partial side by side tear down id like to know too

Either one should work. Use whichever one is in better shape...

whats up guys i just joined this forunm about 5 min ago. I have a 93 prelude s w/the f22a1 in it that just got totaled by some dumbass driver who hit me so im pickin up a 95 si this week. the Si has the "G22" swap 100% complete in it. Im going to get it compression and leak down tested before i buy it. i did test drive it however and i have got to say the car is wicked fast. ill keep everyone posted as to whats up. but i been doin as much research on it as possible and stumbled upon this thread. motor is legit
