Its the same as a H22 10.6:1

This is an awesome thread, I also have this engine paired up with T2T4 tranny.
Thanks for all the effort you put in.

Anymore updates

Re: (H23aEG)
 

Not yet. The other head is off already just waiting on some OEM retainers from Majestic Honda. Supposed to be in tomorrow, then I'm supposed to take the OEM retainers and head over to Portflow in the morning... that's if Tom is in tomorrow. Otherwise, I won't be able to get the head to him sometime next week. Tom said he should be done in 2-3 days with the head.

I'm flying out to Seattle for the weekend next week, so that'll set me back a week. Realistically, it should be in and tuned in 2 weeks. I still haven't ordered a head gasket yet, I'm gonna have to wait till Tom looks at it and gives me a measurement. Sorry, it's gonna be a little bit before the next dyno sheet.

IS THE H23VTEC CRANK FORGED LIKE THE H22?
NICE NUMBERS

Re: (alterdcreations)
 

Awsome numbers https://honda-tech.com/forums/images/smilies/emthup.gif

Re: (alterdcreations)
 

I believe the crank is a forged unit. The oem redline is 7300, so I'm guessing it's forged and balanced.

Re: (precord96)
 

usdm is not forged, it is cast. i like cause it weighs way lees than the h22 one. the jdm h23 it is forged

Re: (AWOC)
 

Here's some updates. The clutch is broken in now, and I've gotten to punch it a few times. No traction in first gear once the rpm's hit 4k, just wheel spin all the way into 2nd.

I picked up the head from Tom @ Portflow today. Big https://honda-tech.com/forums/images/smilies/emthup.gif to Tom, great service and very timely. He stayed late for me to pick up the head after work + traffic. He performed a valvejob and a very slight resurface (0.003"). He cleaned up the head and its looks great. Remember this head has an Alaniz street master port job performed on it already. Joe took some material out of the chambers so the compression shouldn't be too much higher than stock, especially because I'm going to be running a .045" cometic gasket. The head has a total of .028" taken off of it so far, so I decided to run a thicker gasket for some extra room. The JUN ti retainers were replaced w/ new OEM retainers due to being beaten up for 80k+ miles on them.

Unfortunately I'm going out to Seattle for the weekend and won't be able to install the head this weekend. I should be installing the head next Saturday and then I'll be working on Sunday, so I'll tune it after the last car on Sunday. So please be patient... Sorry for the wait, but I'm just as anxious to see what it will do.

so what better i going to build this same set-up but high compression, if any one can help if i use h23 botton with h23 rods what pistons to i use and i am going to be using an h22 head also built any help thanks!!! https://honda-tech.com/forums/images...es/emsmile.gif https://honda-tech.com/forums/images...es/emsmile.gif https://honda-tech.com/forums/images...es/emsmile.gif

Re: (precord96)
 

wow the head looks great. https://honda-tech.com/forums/images/smilies/emthup.gif hope to see some numbers soon.

Re: (92bluepreludeSi)
 

Looks great!! Bump for one hell of a torque monster!! After reading this thread...I think I want one. I'd be way faster than the LS-V I'm building. I can't find a site that sells them though. Anyone have more info on the h2b trans conversion? This looks like something that would be way worth the time and money. I know its gonna take a lot to fit one in a DA, but I think it would be more worth it to get this engine, then pay 6000 for a LS-V setup.

I got my motor from Osaka Motors in Canada.The only thing is if you have them ship you one,you never know what you get.So thats why i went and picked mine out.As far as the H2B goes only one company that i know of that makes the conversion is Quartersports.If your going to buy the conversion make sure you only buy it from them.Alot of people have been scammed by imitations.H2b can outperform LS-V anytime of the weak.Aint nothing like a toqure monster.

I have a similar setup to what you have:
stock H23A bottom end (removed the balance shafts)
Well ported head with Crower 3 cams
Blacktrax Intake manifold
Hytech Header
Street tuned with an AEM EMS
etc.

I'm loving the motor, especially after I put a more aggresive ignition map on it last week, & hope to dyno tune it soon, but look forward to seeing your #'s if you're able to do it before I do. I'm shooting for around 220 whp.

Re: (H23aEG)
 

Yeah, I think I'm gonna do it! I just need to do some research to find out about some mounts, and how to get it to fit in a DA. I checked out Quartersports, and their stuff looks great. I'm just not sure how the b trans is gonna hold up to that much torque. I guess I'm gonna need a good clutch, a good diff, and some good axles. And I might have to talk to Tom at portflow to see what he can do with it!!! That'd be great to have Honda's big block in a DA...nobody would expect it at all, even the v8 boyz would get their feelings hurt unless they are built or on boost!

Well Quartersports has there H2b in there DA.Dont worry the trans holds up fine get yourself a nice clutch and flywheel setup and get yourself a Quaife LSD

There are a couple options now for putting it in a DA like H2b, & ExplicitSpeed kit (I thought Hasport had, but it appears they haven't yet). I used the Hasport kit to put the H23A I have in my EF & boy is it quick (info is here https://honda-tech.com/zerothread?id=1646586). You'll certainly enjoy having one in your DA.

Re: (2lude4u)
 

Heard that the best way to put one in a DA is to sit the engine on the crossmember, and find a way to weld the stock mount to it. Nobody has mounts anywhere, and judging by the time it took for someone to come out with performance mounts, I doubt it'll happen anytime soon. I'm gonna call around and see if I can't get some fabbed. Yeah, this sure as hell beats the idea of an LS-V anyday!

Another thing...I think someone said the blue top h23a only comes with an auto trans. I've found two sites that offer them with 5 speed. Maybe they just put a cheap USDM h22 trans in the crate or something.

Most companies know that buyers don't want auto trannies, so they'll sell H23A's w/out a tranny or mate it with a JDM tranny.

Re: (2lude4u)
 

That flycut surfaced head is ballin'! https://honda-tech.com/forums/images/smilies/emthup.gif https://honda-tech.com/forums/images/smilies/emthup.gif

Re: (djphonics)
 

Well, got the head and cams on yesterday and tuned it today after work. I'm a bit disappointed on the power. I thought it would make a whole lot more power than the H22A. It didn't. It makes 237.0 hp @7349rpms and the H22A made 240.9hp @8107rpms, the H23A with I/H/E made 221hp @7022rpms. It's down about 4hp on the H22A and picked up 16hp over the H23A. The torque is good though. It now makes 198.3 lb/ft @5255rpms and the H22A made 180.6 lb/ft @5483rpms. The RED is the H23A with I/H/E Alaniz head and JUN cams. The YELLOW is the H23A with just I/H/E, and the PURPLE is the H22A with I/H/E Alaniz head and JUN cams. The H23A has lower compression than the H22A. I'd say its roughly .25:1 less than the H22A so not much. One thing to note is that the vtec lobe on theOEM cams in the H23A were pretty big, almost as big as the JUN's, but the primary/secondaries were much smaller than the JUN's.

get some track times. Cuz the thing is making alot more tq and alot more mid-range then before.
