this guy did it alittle ghetto but it gives the basic idea of doin a frankenstein head swap alternative to the total h22 swap.

basically the h23 and f22 have the same exact stroke. slap an h22 head and some other things and your pushin bout 186hp to the wheels. i have dyno's at home of a bone stock h23/h22 frankenstein. remind you thats BONE STOCK.

the f23 has a slightly higher compression ratio but you can use the h22 pistons on the f23 block and come up with about the same result. im doin a h23/h22 frankenstein this weekend so ill post as many pics as i can bare to take and maybee ill post a write up if yall ask nicley.


your friendly neighborhood brown guy.

 

with the dohc head do you get teh dohc sensation becuase you should


seeing as tho since you have 2 cams theres enough room to get the lift portion of vtec (why you cant feel it on a sohc)

 

yea you get around 170flbs of torque with the frankenstein. the numbers are pretty good considering its still na. plus those are bone stock numbers. stock intake and stock header.

 

very very good find!








btw, your not a smartass anymore

 

thank you

 

link no work

i always wanted to do this but people always said that it wont work...

 

you're my favorite friendly neighborhood brown guy (you still coming to markham on the 12th btw?)

something doesnt add up. Im making more power than he is with just a little less torque ( well, 10 foot pounds ) and im at 9:5:1 am i missing something ?

 

I think he's on stock internals from the two engines (or mostly stock internals)

 

 

what an interesting read. My god, Im so fucking ready to buy a test dummy f22 block and an h22 head, leave it at a shop for 6~ months and slowly buy the parts needed to make a amonster of an engine...

 

"my preccccccccccccccccccccccccccious" "take it to da carrr' wash. Ged it'd waxxed !!"

 

what teh fuck?

Anyways, if this engine is making those numbers on stock internals more or less, what do you think it could do on aftermarket parts? How much of a bump do you think?

Anyone?

 

im very interested in this

 

remember his experiment is on the h23 NON VTEC HEAD. im doing basically the same thing on my friends h23 lude except with stock h23 lower and H22 HEAD its been dyno proven to produce 186hp TO THE WHEELS BONE STOCK. its pretty much a stroker h22.

something doesnt add up. Im making more power than he is with just a little less torque ( well, 10 foot pounds ) and im at 9:5:1 am i missing something ?

i thought the f2x only put down like 130hp to the wheels stock. which means a 50 hp gain over stock f2x.. with out intake headers and vtec controller pullies, and other misc. aftermarket items.

the only downfall is it does raise the compression ratio considerably.. somewhere near 11:1 cr. which isnt too good for turbo and such. but you could turbo and use 5psi all day. and be somewhere around 220whp.



another site with more pics of f23/h22 head swap..

remember these are non vtec f23's they are using for the bottom end.



ive been lookin for the dyno sheet of the stock h23/h22 frankenstein but i cant find it.. im at work now and i know i have it on the comp at home, so ill post it up when i get home in the am.

also my we jsut bought a h22a4 w thrown rod for a spare motor and it seems as tho we have an extra head and intake manifold.

 

prolly closer to 190whp with bolt ons.

also there is a few differences between the f23 and h22 as far as the head gsket goes. but you can fill in the spots thats alittle different.. ill go more into this after our swap is complete.

if anyone in tampa knows where i can get a f23 block from hit me up. so maybee i can put togather the first cl g23 (f23/h22). im fawkin pumped about doin this swap.

 

I had full bolt ons .. the works as far as "bolt on" modification goes. I produce good numbers on stock internals . With bolt on's i still produce some 186.4 hp after internals and mild tunning. so i just cant see how that swap with much higher compression, produces less ? They got me on torque but ( they got me on cost too ) i got it !! The cam regrind.. i completely forgot about that

 

then immagine the gains that motor would have with the same exact mods you got done to your f2x.

elaborate more on this cam regrind.. cost, specs.. interested in learning new things. i dont know much bout the f2x motor.

and what mods you gots done that give you an extra 50+ hp to the wheels.

 

and if you do the head swap yourself its only bout 500$. im sure just the cam regrind costed around that much.

i looked at your mods on another post. like i said add those mods to the h22 head swap, your pushin over 220+ to the wheels. it gives you a better starting point. as to where your f2x is pretty much tapped out as far as upgrades and your producing about what this swap produces stock.

 

This swap is getting more and more common nowdays. It's like a budget motor build imo. The low end is alright, just wish the hi end was better.

 

i dont know if im gonna make it.. im still waiting for my fawkin wheel to come in.. now the peeps i bought them from is sayin its not covered because it cracked from the tire being underinflated. (35psi).. then the dude fawked up and said for every inch you go up in rim size you add 3 psi.. well the rear stock tire pressure is 29 psi. so now they have no leg to stand on. i think im goin to take them to small claims court. this is rediculous. i mean you can make up any excuse as to why the rim is cracked in 4 places. theres not one scratch on them so it wasent impact, tire pressure was dead on. i think theyll say that i went over too many speed bumps next. anyways ill try to make it. but i cant drive all that way on a spare. especially goin thru alligator alley.

 

wilp, i noticed alot of 2.3s doing this, would this be different from a 2.2?

 

i know the h23 and f22 crank has the same stroke on the crank. im pretty sure it is the same as the f23 except the compression ratio will be alot lower due to the shorter piston. prolly around 9.5-10:1. i have tons of research to do still. mainly just crank, pushrod, piston, head mesurments. shouldnt take me long to figure all this out. ill draw up a theoretical application with specs. (an educated guess as to what the outcome measurments are supposed to be).. the main problem is always fitment (which hs been proven to be easily fixable), and valve clearence which is also fixable. its just a matter of what parts to use with which applications.

 

sounds good

 

hmm . .. . this is a repost =(
lol i was thinking about this but wasn't too sure about the head of the h22 to my bottom f23 =/
would it actually fit perfectly? i remember someone doing it on H-tech and he had to do a lil something to the gaskets or something. . don't remember

 

now us 3.0 people have to figure out how to swap over NSX heads... cause we all know how cheap and easy it is to get DOHC nsx heads to swap to


if its even possible

 

i never said this was new information. im only puttin this out there because ive never heard of any cl doin a g23 swap.

the modification to the gasket your talkin bout is the oil drain crevist.

in all cases of people doin this they have used hondabond to fill in part of the crevist.



everything else is just plug and play..

im pretty sure the only difference between using the f23 block and the f22 block would be compression ratio. the f22 would be better for spray/nitrous and would prolly have a 9.5:1 cr. as to where the f23 would have closer to a 10.5:1 ratio. still boostable, but not as much.

 

I could probably find one down here in Miami and I'd be willing to make the drive up there if you dump the frankenstein into my ebay

hell, i'll buy the block myself and get it moved up if you'd be willing to do that work for me ;p

 

hmm. . .sounds pretty fun to do. . i think imma try this =) if it's actually plug and play . . .but what about the timing belt and etc. cause it's now DOHC. . . get a newe one? lol

 

yea youd need a new one, you need the one for the h22, and youl need the lower timing gear fromt an h22 also. the one that goes around the crank.

the only other thing youll need thats not on the h22 head or your car is the p13 ecu. you can use a p72, p28, p13, and im not too sure on using your factory ecu. ill have to look it up.

 

are you gonna make a write up or no?

 

that would be great!

 

How much is this going to cost u total?

 

bout 1000$. start to fin.

plus we can sell old head, intake mani, etc.

ill be starting as soon as my homeboy gets off work 1530. 330 for you civilians.

 

Someone offerd me $1200 for h22a with tranny. Hmm

 

Hmm... Sounds like a damn good deal to me granted the engine and tranny is in good condition.

 

does it matter if it's an auto? well planning to tranny swap later but about the ecu and auto . . . will it work?
do i have to get an ecu from an auto or it doesn't matter =/

 

well? Any word? Whats up wil? Give us an update!

 

now if u do the h22 head on the f22 block, would you need to get a different ecu, or could u just get it reprogrammed? If you need a new one, which one would u go with? I am really thinking of doing this to my CL

 

get the auto ecu you can modify the wires to go around the park neutral start switch, rev limiter, etc.
