Hey, I have a h23 and I want to keep it and go all motor. I know that that is not what everyone recomends, but I still want to. My ? is will the JDM H22 type-s pistons fit in the H23. (both bores are 87 mm.) Will my c/r change and what will it be. Also what about the regular 10.6 to 1 h22 pistons.

 

I think since the h23 combustion chamber is smaller it raises the comp a lot more, but I would look it up

 

honestly dude this question has been dealt with a thousand times... I'm not flaming but a motor build takes alot of research and you have to be willing to find this **** through searching. Your compression ratio does jump to around 11:1 and there is an issue with the wrist pins (some are floating) Hope that helps, just remember searching is king.

 

Thanks for the input, but I searched, not only here but other forums as well. From what I've found the bore is 87 on both h23 and h22. I have been doing the research and thought since I am planning on spending a lot of cash on cams,p&p,springs,ret ect.., I could save by not sleeving my block. I do not know the formula for calculating c/r based on bore,stroke and piston size.

 

bok, I do not have access to im. send me your email to ernie2409@hotmail.com

 

I'm just gonna go ahead and say it...

You will not build a "fast" car by building an H23 all motor.

 

Maybe not as fast as turbo, but my goal is a daily driver w/ about 200 whp. This is my first attemp at modding my car.

 

the 11.0:1 type-s pistons will get you around 11.7:1 (someone correct me if i'm wrong). not too sure about where the 10.6:1 jdm h22 pistons or the 10.0:1 usdm h22 pistons will get you to. you should ask piratemcfred or hondafiend04. they both have some high compression non-vtec motors.

all motor h23's can be fast....dont sleep on the non vtec's thats all i can say....in the end no **** the h22 will be faster, but i've handed a lot of h22's their asses...

Even if that is true, look how much you spent on your H23 build compared to the stock H22's that you beat. Not worth it in my opinion.

I thought about building my H23 before I got my H22. I knew that after all the money, time researching, car downtime, and effort running around to get work done, it would NEVER be an h22. Besides, after parting out my H23 motor, tranny, and ECU and the spare H22 parts that came with my H22 swap, my H22 swap only cost me $100. ....and I don't regret it ONE bit.

You would have to have your h23 rods rebushed to accept
floating rist pin design of the type s pistons.

I'd look for a set of jdm h22 pistons, that would probably
put you around 11.2:1 compression.

 

I;m running 13.5 all motor h23 full interior with some heavy *** 18" konig imagines (45 lbs per wheel tire combo) with a stock I.M. and a crappy dc sports header with no collector mod. Is that not fast?

if that is true, then yeah, that pretty fast

yeah i said in the end the h22 will still be faster, but dont tell me that there arent fast h23's or with the potential atleast cuz thats bs....

 

Hey more power to you H23 all motor guys if you think its worth the thousands it'll cost ya just to put down what a H22 will do with just I/H/E.

 

If I was going to mess with a NON-VTEC motor, I would do the G23 hybrid. Seems like a GREAT motor for a daily driver. Not too expensive either.

Monday and already another thread on h22 pistons in a h23. For you people who whine about not finding anything by searching, I just searched on 'h23 piston' and had 99 hits just in recent content, including the thread from a few days ago. Please search, and if you don't want to then start here:

As I mentioned in the last thread like this, the hybrid/monster threads in the prelude forum have covered this topic well, and if you read them you will learn a lot of related info.

You guys are forgetting that the h22 pistons are taller. Depending on whos number you use for the piston height (~.020 taller), I calculate about 11.5:1 with stock USDM (10:1) h22 pistons in a h23. JDM and JDM Type-S are even higher (about 12.3 and 12.8). This has also been covered well in the threads I mentioned.

 

Since I am one of the minorities advocating mild built nonVTECs instead of a swap right off the bat, I have to put my 2¢ in. For the people that already have an H23 and I/H/E in their lude, it is cheaper than the JDM H22 Swap to get similar numbers.

H22 pistons/rings new $300 ($150 used pistons/new rings)
H23 bearings $110 (if needed)
H23 cylinder hone $100
H23 Cams/springs/retainers $550
P75/72/28/06 ECU with basemap $150

And that'll probably get you to about the same power to the wheel as the H22 swap but with more torque.

Of course this is a lame idea if you already have an H22. Then $1000 can get you a lot more but H23 nonvtec still has potential dollar for dollar, for the guy who just wants more pep in his pig. H22 are good for top-end (drag racing) H23 are good for midrange (street/tight roadcourse/autocross).

Both are fun but everyone hates the H23 for no good reason.

Don't get me wrong brother, i'm not hating, i'm just saying it's a lot of money, and the numbers still won't eclipse a built h22.

 

I appreciate all of your input. When I searched I got a little here and a little there. I know it is annoying to get the same crap posted over and over, for that I appoligize. I just want to do the best mods possible without wasting my time/$ and/or destroying my car. I read somewhere that if I use Jdm odb1 pistons from h22 I do not need any mod. I don't need my h23 to be faster than modified h22's just a good amount faster than it is now. I think adding 75 hp to the wheels will be more than enough.

I'm not trying to start a war here but I had an h22 in my car and sold it to build an h23 so lets not pretend that you can't off set costs by selling parts to fund an h23 as well. I actually made money building my motor and I doubt there is more that a hand full of h22' s that are going to run me down, not that I'm super fast or anything. And besides if I was all about going fast for as cheap as possible I'd buy a 5.0 mustang and be a geek like every other guy that drives a 5.0 but I chose the road less travelled and went with honda and took it one step further and went non-vtec. What can I say I love it when I step on it @ 3000rpms and it takes off

What makes the h22 so much better? Esp up top? Does the h22 head breathe that much better? Is the it the vtec lobe for the cams? How aggressive of a cam profile cam you go with h23 cams and still be streetable w/ decent idle? Any way to make the h23 rev as high...at all?
