N/A h23a1 non vtec 180whp 180wtq???
I'm going to be doing my very first build this december.
I drive a 94 si(if you want to see it youtube eg2171)with an h23 I like the tq, and the way it pulls. There is no way I'm swapping out for an h22 out of the question. Maybe down the road.
I have read forums extensively on 1/4 times,dynos,and builds of h23s.Stock 1/4 15.6 bolt-ons some runing low 15's and the fastest I read about was a cammed out Si doing mid 14's.Now to the dynos in stock form it makes more tq then hp most of the time.I stock dynos about 140 whp 140 wtq.One guy had a home made cai, dc headers,stock exhaust system with stage one crower cams.He made 161 whp and 159 wtq no tune.
My goals are 180+ whp and 180+ wtq and very low 14's on street tires and 13's with slicks.I heard h23's respond well to mods.It is a 2.3 that's a big L4 engine which I think has potential in a N/A build.
My plan of attack!
Cold air intake"aem "
Dc headers or obx headers
exhaust "still researching"
Aftermarket TB
aftermarket intake manifold or or port stock
Jdm type S pistons
Crower stage 2 camshaft and springs and retainers kit
LS ecu to use with hondata
LSD h22a or a f20b trans
Stage 2 clutch
Light flywheel
shortshifter
I'll probably be runing some 225/45/16
Some other parts of this build will include some red jdm dc2 or dc5 seats.I know honda never made a prelude type R my theme is going to be based on type R red.
I'm just sharing this with everyone maybe gets some opinions or thoughts on my plans.

Based on what your goals are and the modifications to the H23 you have outlined it is probably going to be cheaper and less time consuming to swap an H22 and get a nice header, exhaust, and dyno tune. With those things you will probably be at your power goal without having to take the motor apart like you are planning to do with the H23. If you are on a budget, you could reuse the m2s4 tranny you have now with the h22; the power goal and type of racing you want to do you don't necessarily need a LSD....especially if you run some slicks.

What he said!
I ran down to a 14.8 on drag radials, with a stock jdm H22, my old H23 tranny, with ebay header, short ram intake, and Thermal exhaust. Only tuning was lowered VTEC point with a Neo to stay in VTEC on the 1-2 shift. This was at elevation of 3500 ft, so it was low 14's at sea level. This setup had me probably roughly 21-2200 dollars all in, doing the work myself.
It cost me another 900+ for an lsd tranny, and by finding killer deals and doing all the work myself again, I built my new setup, which dropped me to low 14's at this altitude, for another 600 or so. If I had to trust the car to be my daily, I would not have built this engine, as I do have the constant worry that I may spin a bearing, even with all the work I did to increase oiling to the crank.

180tq out of a stock bottom, mild camshafts and mild bolt ons is a bit of a stretch imo. The amount of rpm the engine is going to want to spin with a well breathing system is asking for a spun rod bearing. If you tear the bottom end down, change the clearances and balance the rotating assembly you will be much better off. But if you go that route you might as well beef it up and raise the compression.
Just an experienced opinion.

An h22 has more torque than an h23, but regardless.
I think FI is still the cheapest way to go to make big power.

I think this is a realistic goal taking the example I gave of someone that made 160 hp 160 tq with only an intake, headers, and stage 1s"redline 7k rpms"no tuning whats so ever.
H23's are very strong motors I kept up with cars that have a lot more power and torque and beat every car in my class( Ls,b16,ka24,95 v8 stang ect ).I have miss shifted a few times and it still runs strong.

My original plan was to buy a Civic with an h22 in it already and shoot for 12s all motor with slicks.I can afford an h22 Civic in december,but I rather have a 13 sec prelude then a 12 sec Civic.H23 has the potential to be fast.

Re: N/A h23a1 non vtec 180whp 180wtq???
I kno h23 are not pulling more torque out of .1 L more than h22. From looking at a ton of ppls dynos and setups. I havent seen an NA h22 get over 170 tq when they're making 270 hp. And h22s are easier and more efficient to tune since they have vtec. H22s easily make better power even if u dont want to change your mind. It does seem a bit of a stretch for h23s

I'll keep my H23 thank you. H22 is nice and all but the expression you get when people say "what it's the h23 motor?!?!?!"

Re: N/A h23a1 non vtec 180whp 180wtq???
Man everyone puts the H23 down. No one's comparing apples to apples.
Assuming the same cam spec, compression, induction components, tuning etc the H23 will make more torqe than the venerable H22. My nonVTEC "H23" made 183 wtq with good compression and "mild" cams through a POS DC header. It took a few dollars to get it to make 200whp/183wtq but it cost me less than an H22 swap.
A few dollars more and now I'm making 220/191 though the same POS header on OEM cams. That extra .151 liter makes a good bit more torque than your H22.

Well start by building the bottom end, and get it running with the H23 head......
Then, when you get frustrated with the lack of power, you can just swap an H22 head on there, and then start REALLY enjoying H power.....

And I didn't say that to be mean......But it was my mental-build to finally scratch this damn Non-VTEC itch I have had since my D series days......I have decided its not even worth the time though.....

Re: N/A h23a1 non vtec 180whp 180wtq???
I'm not the type that like the high reving motors I prefer torque. Torque does make a difference for example a mild build b16 making 165 and 114tq but revs to 8600 rpms. An h23 with a mild build172 and 165 7000 rpms. I'd put my money on the prelude but might be close.If both motors were in the same ef or civic body there wouldnt even be a race to watch.
When I go vtec I'm getting that 197 hp 163tq bluetop h23 and build something like 98 vtec's build.

Same goes with the "LS" B's. A lot of time and money spent on building with very little to show for it.
Things that will stand in your way:
1) Header----DC/OBX is trash, you'll need something custom for real results<--#1 thing that stood in my way, and $1k for something custom, that IS H23 specific
2) Crower-----I assume lack-luster results like their H22 cams
Check them out if you're serious, Again you're still spending $$$ on H23 specific parts
http://gude.com/Cams/cam_prelude.html
3) Intake Manifold----Some things that can be done with stock, but again $$$ on H23 specific parts
So think about how much $$$ you'll spend on H23 specific parts to make OK power. Then think about someone like myself making 204whp/160tq with a stock JDM bottom end and $2k head with a $400 header....
These are things that every serious H23nv owner has faced......Most of them either Boosted, Sprayed, JUST i/h/e, OR dropped in an H22
Honestly, the exhaust is the easiest part of your build. 3" with Muffler/Resonator of your choice! Don't even bother with off the shelf systems.....
I'd stick with your H23 trans and spend the money elsewhere.....don't believe the HYPE that the gearing is "that" different. The average person wouldn't even know the difference between them.
Its the F22 trans that has shitty gearing.
I think this is the 1st time I have admitted a Non-VTEC itch in public---Puts on flame-suit......lol

Re: N/A h23a1 non vtec 180whp 180wtq???
You'd guess with almost 20yrs under its belt, more people would've built a non-vtec H23........Don't you suppose there's a reason nobody has done more with it???

Actually I agree with you 100% about non vtec not showing good results for the time and money.I wouldn't even think about building a nontec.What I'm defending is the h23 not if a nonvtec can make power.The h23 was made to make good tor not rev high or make tons of power.
1. Pos headers from dc and obx
I went to cb7tuner forum an theirs a lot of them with h23 swaps.They say the f22 and h23 have the same bolt pattern for headers. This means I can have bisi make some headers for my build now I'm in business. I dont mind paying and I have seen the price for a piece You have to pay to play.
2.idk about the crower cams made for the h22 but people get great results with h23's.They have been dyno and make power all the way to 6500 instead of falling off at around 5800.They increase power and tor at all rpms levels and brings the redline to 7000 with only stage 1's no springs or retainers or any other head work.
Like I said I'm not into nonvtec I'm looking to building a tq monster and the h23 is a good option with its 2.3 liters. I would never buy nonvtec cams for my b20 integra i would put a b16 head to make power so hmm yeah I'm not some type of nonvtec follower.

I loved your project! Did you know that here in HT (H22 Lover) you would be crucified. Plus I admire your project and how I live in Brazil where the vtec engines are rare and can not buy here and used engine in the U.S.. And PROHIBITED.
And I have an H23 and would not use it with turbo and yes N / A cool how your project! Want to know more details of the project, such as stilts, videos, photos ... You could create a How To topic as your project to inspire.
Sorry my English
