is there any potential in the H23?? what can you do to make more power. And does anyone in here have a built up H23??

 

there's a ton of potential, just parts are not as easy to get as the vtec! but if your gonna build up you engine all motor, i would suggest swaping in the h22a and going from there, much more parts, and a little more potential, cause of vtec!

 

Hahaha. WTF. You said yes. Then said that he better do a swap for the H22A. The point of the question is he wants to build the H23.

Internals, pnp, exhaust. Tons... N/A isn't just bolt-ons.

I dont know if he is on this board or not ,but I know someone around here that has ran a 13.9 with just a built head on a H23 stock block now he has a built H22A (high comp) block with the same built head. Hopefully he will go to the track soon. Because I would like to see this car in action. I have met him and seen the car, but just not seen it run.

Long story on how he ended up with the H23 head on a H22A block.

thats the first ive ever heard of a h23 head on a h22 block... he's turning out some good times though.

 

Yeah thats me.The 13.9 was a one time only with slicks.There is a lot of potential in the h23.I just had some dyno time and the hp was ok (180) but the tq was amazing (170) and the curve was consistantly 25 hp and 35 tq over any h22 he had on record.The only time the h22 pulled me was from 7000-8000 but everywhere else i spanked them.We had a detonation problem so we are working on that right now when we fix it we are hoping for 200 hp.

 

cool, i think that if you had an h23, a better way to spend money would be to build and turbo it. An h22 has better n/a potential. All hope isn't lost though. You can make an h23 fast n/a, you just need to spend more time and money than you would on an h22. I've always wanted to build my h23 for n/a just so i could beat people then tell em i was n/a non vtec but i just don't have the money. Built h23 and turbo would be faster too.

 

The torque that could be had from an H23 force fed would be astounding ... definatly the engine to shove air into

 

h23vtec ownz everyone

 

although i intend on putting a turbo on my h23a, i can tell you that you can build up an h23a with not much problem. It just takes a little research but the parts are there. It is not worth buying a whole different engine(h22a). You can find the parts you need for the h23a..Just takes a little work and that's part of the fun. Good Luck

 

until it breaks. it doesnt own me

 

you my friend, will be proven wrong about the whole H23VTEC...and i will see to it

all in good fun of course

 

aha i doubt it. how much boost u running now anthony 16-18? get that 4b workin right? who tunes that **** around us? get on the dyno damnit.

Oh...so that's y i saw a guy at the track with a h23vtec with i/h/e hitting 15.3-15.4, and i'm hittin 15.6-15.7 in a stock h23. So let me get this straight. I wanna spend all that money to drop 3 tenths in the 1/4, when i can just save that money and just build and boost the **** outta my h23

 

if its running 15.3 or anywhere near that its messed up. with a propery tuned stock h23VTEC (not the accord one) i saw a dyno chart at 177 to the wheels with a CAI.

granted this does sound high because h22 VTECs only get like 155 or something like that to the wheels

 

for your sake i hope you prove me wrong. ive seen 2 of these motors fail IN PERSON, and in a very short amount of time. i also heard of the guy that ran the 15.3 on the quarter with this set up. With that amount of money spent on the swap, IMO it is a waste of money, but im sure he wasnt tuned properly and had a few bugs to work out (no sarcasm at all). If i were to go vtec, i would get the WHOLE h22a and hit an easy high 14 with intake header and exhaust. If you want to talk about boosting the hybrid, then ill be happy to talk about how the cam profile overlap of turbo cams hinders performance of turbocharged applications. However, i have "heard" of some real power ****** in the ones that do run right. The point in the hybrid is to combine the power of the h22a head and the torque of the h23a block correct? Well lets see....

H22a
190 hp @ 6800 rpm and 158 lb/ft @ 5500 rpm

h23a
160 hp @ 5800 and 156 ft. lbs of torque @ 4500

You guys do the math as well as the logic to relate this to the point of the hybrid. You are looking at an easy $2000 on this swap done by a reputable shop for parts and labor. And yes, if you are a good mechanic common sense tells us you can save on labor. That is an *** of money to spend to gain that amount of horsepower and torque in my opinion, and yes with more mods youll gain more power which will make the motor perform even better. But thats the case in ANY motor you build. You might prove me wrong about the h23vtec by showing me it runs, but theres no way this hybrid just the way it is will prove me wrong running against me on the track Im not trying to sound like a cocky dick, im just simply stating facts from research and personal experience. I do wish you the best of luck on your project and i hope you turn out some bad *** time slips, as for me im staying strict h23a with 18 pounds of boost

i understand where you're coming from...i actually tried it a few years back, but due to lack of knowledge, lack of shop support in this city, and lack of tools/time to do it myself, i failed. This time I will not fail, and I will see to that.

and for what power? this:


186 hp 151 lb-ft

2.3 SI bottom end
2.2 VTEC head
Prelude Type S Pistons.
Everything else stock.
Stock headers, stock intake, stock exhaust
stock cam gears, stock fuel system
In other words, totally stock except S pistons.

I'm going with rods (probably crower), rod bolts, type s pistons, and probably a stock, for now, H22 head. should be about $2000. I have a lot of misc parts from the last attempt and way more knowledge. And yes, i will do the labor myself.

But $2000, for that kind of power, I'm all over it. I'm only gonna rev to the stock h22 redline, and i think with the rods/bolts i should be alright as far as reliability.

but blah blah blah...its been tried, some have succeded, some have failed.

I will not fail. btw: what would a stock jdm h22 short block go for? like if i was to sell one? actually i might keep it for back up....

anyways, you and i both know the 15.3 car wasn't running right...so don't use that as an example of what time its going to run.

I'll keep you all updated, this is going to be fun

 

you can make a h23 fast as ****, some people say to put a h22 head on the h23 block, which tuned right, is supposed to let you run between 12 's and 13's...

 

good ******* luck doing this on a STOCK h23a block and h22a head.

F23, good luck in your project, its always good doing things yourself... you save on labor and can sit back and pat yourself on your back for a job well done

 

h23 head, not h22

 

ah snap! for me, i suck at reeding!

 

you suck at speeling also

 

well you see, reeding and speeling were both taught to me by the same teacher. so its his fault i say!
