H22 Head On A H23 Block?

[MR.H23]

Hey People Whats Up!

I Want To Put A H22 Head On My H23 Block. But I Have A Question, Should I Swap Out The H23 For A Complete H22 Vetch, Or It Will Pull Harder With H22 Head On A H23 Block? I Really Need Some Help On This People......thanks

[Prelude13]

I would rather do a complete motor swap instead of doing a frankenstein h22/h23 hybrid.
It's not really about "pulling" harder.
It's about creating a hybrid motor that will not self destruct.
Think about it, h23 block that redlines at 6500ish and a motor h22 that redlines at 7500ish, you do math on work.
It has been done, but that's not a very popular swap IMO...

Now, a direct replacement JDM H22 motor should run you perhaps $1600?


Cost wise and it'll save you tons of money on aspirin.

:cool:

welcome to the board!

[bc2_bb6]

An h23 vtec from the Accord SIR goes for $1,850 shipped to any where in the U.S.

oh yeah its spelled VTEC

anyway if you want to do the motor don't be discouraged as some people get the joy from the project itself not the end result.

[bc2_bb6]

a JDM h22a goes for $1,000 and you can do the swap on your own if your still looking for a project.

[Rory]

That kinda mod doesnt last to long on the motor...

[bc2_bb6]

here's the link for the h23 vtec:

Personally I would swap a complete h22 in the car. If you want the torgue of the h23 and the power of Vtec. Take the Crankshaft out of the h23 get it balanced and put it in the h22 with the h23 rods and h22 pistons. But make sure to get the type-s 0versized pistons and put floating wrist pins in the rods. You will have a completely stock N/A monster with Vtec at 5500 rpms and 12.2:1 compression to back it up. You can also calculate how much horsepower you'll get from the build. For every .1 of compression increase= 1 wheel hp. so going from 9.8:1 -to- 12.2:1 = around 24 hp just off compression. Now you add I/H/E and it puts you in between 30-40 extra hp on top of the stock 200-220. Add crower stage 2 cams and a good tune and you got another 15-22 hp. I can go with this all day. But just do the complete H22 swap and be happy.

h22 head would be cheaper. But the compression would be below 10.0:1, which is stock compression for h22. Would need to change the pistons to make some power with it NA and that takes time.

h23vtec ftw

[dakilla4ever]

True cheaper at the beginning but in order for that to run successfully on a daily basis your gonna have to do alot to it. Specially seeing that the stock h23 crank will give out on you past 6500-7000, and the h22 head is gonna push it right up to 7500. So with that said you also gonna need the h22 oil squirters. And its so hard to find those its ridiculous. Plus the long list of stuff you have to change over with the head. Basically everything that touches the h22 timing belt.

who says the crank will give out on you? Get it balanced and you wont have any problems. Balancing of the crank, pistons and rods....along with micropolishing the crank ran me 240 dollars at my local machine shop. Not too shabby.

AllMotorRandy on HT is revving his "OEM" bottom end with h23 crank to 8500. Has been doing it for 2+ years now. Clearances are half the battle. H23vtec is not a hard swap. There really isnt all that much you have to do. I've spent about 500 dollars on brand new factory parts to make the change over. You can pick up oil squirters for like 50 bux from any wholesale honda dealer.

considering the badass deal i got on my setup, i really havent spent that much money on all the conversion parts. 340 dollars from honda for an oil pump, water pump, water pipe, main seal, oil pickup and misc gaskets and bolts. 100 dollars from a timing belt and the h23 timing conversion parts. You have to run the h22 crank timing gear, which can be had for about 40-50 bux from wholesale dealers.

Theres really not all that much involved with this hybrid. Its just a matter of BUILDING it correctly.

[Si Speed]

With the H23 crank, there aren't any clearance issues with the oil squirters?

i talked to Natalie at Blacktrax and she said they havent had any problems with clearance in the h23 block. I was always under the impression that they had to be bent out of the way, but apparently not. I'll be finding out soon as I go home (parents house) and get the oil squirters from my old motor.

^ you should do a write up, and post up some pics if you took them during your build. I wanna see the progression and the transformation.

i have a writeup going right now in my sig. The idiots that host my forum messed up the other day and they are working on getting it fixed. Check that thread in the next day or so.

[Prelude13]

Damn Blake, your build is gonna be a beast man.

I like to see a successful h23/h22 hybrid done correctly. Looks like you've got it down. I'm used to reading these motors self-destructing because of lubrication issues from the Accord kats who've done this.

What transmission are you mating to this anyway?

thats what im hoping for. 230+ would make me happy....higher...just added bonus.:tongue:

I've got a friend of mine who is basically being my teacher while im doing this build. It's good to learn the correct way to build an engine. :smile:

gonna be using the non LSD JDM tranny for now. Eventually i'll have to get an LSD but i would really love to save that for when i attempt H2B (wayyy down the line)

[Si Speed]

The hybrid builds are really getting my attention. Like B said, I'm used to seeing so many just thrown together and then dying afterwards. Are you goin to leave the H23A1 engine stamp or grind it down and put your own custom stamp?

i never thought about that, lol.

^_^


that would be my stamp

[Si Speed]

H24B (B being after you or whatever you wanna make the last letter) Talk about throwing people off. "Must be JDM."

[ogsmakdade]

I have an ingraver, I can lend it out lol.

[98vtec]

I have an ingraver, I can lend it out lol.

i'm ok for now. I'm sure it will confuse alot of people seeing an h23 stamp and VTEC, in big letters, sitting on top of each other. :tongue:

?que? man, i can see it now.


"where's the turbo?"

"Don't need one."

[dakilla4ever]

The point I was trying to make is it will be less of a pain to just drop an h22 in instead of building an h23vtec and hoping he built it correctly.

[Si Speed]

Less pain, maybe. But with a H23 VTEC, built properly, you get props and personal accomplishment rather than just a buncha money spent on a motor to be like every other H22 Lude.

of course it will be less of a pain, u dont have to do anything but swap the engine if you get an h22, lol.

I have a question i have a 1992 prelude H23 SI. I want to put a h22 vtech head on the motor but i was told that the V tech head wouldnt fit because the h23 is a dual overhead cam, and the h22 is single over head cam is this true or do they make a h22 dual over head cam

hahahahahahahahah

i would suggest that you never listen to whoever told you that information again.
H22's only come in DOHC

There's no such thing as a vtech head. There is also no such thing as a SOHC H22. There is only DOHC H22 VTEC heads. Whoever told you otherwise is sadly mistaking.

I resent that comment elliot.:mad:
I was referring to just buying a stock H22 and not doing anything with it.:wink:

[preludeboy92]

I have a 1992 honda prelude SI with a h23 JDM motor. I do want a vtech head and convert the motor. But i was wondering if anyone could tell me what they thought would be the best motor that i could put in the car. And make it more powerful that it is now thanx.

[my4thgenlude]

the best motor would probably be a K20 or an F20B for the buck but an H22 would probably do, I'm actualli thinkin' about attempting to do a F20C swap after I get the cosmetics right...

[bboi_xtc]

h22a. that's it. this ain't no ls/vtec. lol

[my4thgenlude]

tru, direct swap=H22

[community machanic]

to all the people posting that the h22 does not come in sohc, and laughing at this person. there is a 2.2L sohc motor (atleast in canada) it is a f22b, but it would be alot easier to say there is a 2.2sohc but the h22 is a dohc.

An F22B is not an H22 though. I don't see any logic behind your post. There are are several 2.2L SOHC's.

Hey People Whats Up!

hey wassup man...

I think it's really up to you to make the move... I did an h22 head with an h23 block and it's really strong... the h23 block is stronger than the h22 that's what I think so far... You just got to make sure that you have an h22 vtec harness on the head and get an h22 si ecu.... If you don't get the ecu then you can't get the vtec to kick in... Make sure you put the valves in correct so that they line up together... cuzz if you miss line them then the pistons might hit the valves and that's the end of your motor unless you rebore the whole block and valves and pistons and all that...

Yeah I did the same project on what your thinking about now and it gave me a satisfied run... I ran against an rsx type s and beat him by three cars... I also hang with an subaru wrx all the way too... The only reason I went so fast is because I got new valves and pistons, cam gears, cam shafts, rebuilt tranny, skunk 2 exhaust system, skunk 2 h22 si ecu, injen intake, pacesettlers headers, stage 2 clutch from clutch masters, short shifter, h22 distributor, blox intake manifold, and a skunk 2 racing body throttle.

Yeah, everything is up to you bro... Just do what you think is right... It's your car man just have fun with it...

[92_prelude]

I would rather build and turbo an h23 over the frankenstein.
