Hey fellas. Im in the middle of my h23/vtec build. Ive got a complete h22 and a complete h23. Im using all the necessary components off the h22 to successfully build a h23/vtec. But after thinking about hte h23 bottom end that i will be reusing, i figured i should re-ring it and clean the grime off of it. So to stay on topic, would the h22 rods in the h23 bottom end, with h23 crank, see any differences. ive been different things such as raising the CR to stronger rods. If you have any knowledge in this combo please share!

Heres a link to my build, 56k take a nap:

bump for some help

 

come on guys speak up

 

im in the middle of the same build.....the h22 rods are too long for the h23 block.....im going to run the h23 crank with h23 rods and type s pistons. If u do that too u are goin to have to get floating wrist pins installed on the pistons.....my suggestion do what i just said....the pisons might stick out lik .020 but u can get the rods rebushed so they dont....hopefully this helps...and def would go toa machine shop and ask suggestions

 

yeah i would take it to a shop and get them pressed out but thanks fr the info..

any one else want to add on?

 

you'd want to keep the h23 rods and use the h22 pistons, though the h23 pistons would work too. point is don't use the h22 rods in an h23vtec unless you're having custom pistons made for them

 

just a quick question but someone said the were going ot use the H23 crank instead of the H22, i would imagine this would have a longer stroke, question is would this require a lower rev limit or is that not a problem aslong as it's balanced

 

bump

 

turbocivricerboy, the h22 rods wont work with the h23 crank... You could use the h22 rods if you used the h22 crank though. but then you'd be losing that maddd torque yo.

I believe the h23 crank can handle to rev as high as a stock h22 as long as its balanced.

exactly h22 rods and custom pistons would work, and give u slightly better r/s ratio, but custom pistons requires resleeving...

balance it good, and use proper clearence, use oil squirters. rev it 8 k all day, but mine isnt dd, but i do drive it a few times a week. got 3k miles on it so far

 

thanks for the response on the rev limit, i'm looking into this now, seems like a good route to go for a little more torque. does the longer stroke deal with boost well? i want to go turbo eventually (year or 18 months) and like this long stroke idea allthough i could be on the wrong track here!

see my sig

 

liking the torque on your setup

thats nothing just wait. that tune is overconsertive due to the flywheel didnt have any marks to set base timing. now that i have the base timing set we can runa good tune. this one is about 10 degrees more retarded then it should be and timing=tq! oh and im throwing on a gt35r and whole new turbo setup, not a single piece not getting replaced!

to the op sorry to theard jack, if u have any other questions post up...

IMO Actually that's what you want to do especially all motor. H23 crank H22 rods custom piston is a kick *** stroker motor. My buddy made 276whp/206wtq with this setup. Before anybody calls BS here is a link below

https://honda-tech.com/zerothread?id=1542135

Just something you might want to look into. If your serious about making the most of what you have. The setup is very good and effective just make sure to have everything balanced and you should be good to go

 

by custom piston do you mean forged and therefore a resleeve?

 

yes... in other words, a lot of money is involved. turbociv910 is not trying to spend much money, that can be said for many of the people that do h23vtec.

but that setup is amazing ^ I wonder how much he sold the engine for...

 

so if you wanted to use an H23 crank with H22 rods in an H22 block you would need re-bushed rods or custom pistons?

He sold the car for 6 grand. the 2nd owner ended up selling the engine/trans combo for 3,000 and going back to b series

Yes has to be resleeved. But the conventional Lower budget H23vtec is fine. I ran it for many years in my beater lude before I went on to my turbo project. H23block(H23crank/rods) with type-s pistons and a vtec head kick *** combo with the right bolt ons and EMS 200 whp will not be a problem.

OMFG!! If that weren't the world biggest dumb ***, then I don't know who is. I'd stab a man in the heart for that kind of motor. The B series has no place in the presence of such a motor. That thing makes me wonder about the numbers achievable on lower comp and custom cams.....Oh ho ho I can't wait!

Your telling me! The new owner of the motor is on H-T its going in to an DC integra and they lowered the compression alot its going to be DD . IMO that motor should have stayed the way it was and been ran ***** to the wall.

 

Is he going below 12:1 comp? I could see making it 12:1 and getting a fair (maybe more) compromise on custom cams and something bigger to breathe out of. Then you could still put a serious punishing on the B series nation in the track and still drive away from them to the nearest QT station for some fountain drink delights. Meanwhile, they gotta trailor their high strung torqueless ish on home.

oil squirters have nothing to do with how reliable you can rev. Oil spuirters are used to cool the piston.

im still a little shady about these h23 vtec builds because of the 50mm mains and the amount of stroke.

the 93-97 h22's had 50mm mains but they dont have as much stoke as the h23.

thats just my $.02
