G23??????????

[dabuilding]

so for those of you who have seen the import tuners febuary edition it has an artical about the G23 wich is an f23 with a h22 head with k20 pistons for n/a and f23 for boosted running an 8,8:1 and with the k20 pistons getting 11,5:1 thats pretty sick but i have a question how would this work isnt the f23 a sohc motor my moms accord has the f23a in it and its sohc vtec so if anyone knows more about this please inform me i want to price this build and does anyone know wich wiring harness you would use

[EmminoDaGreat]

F23 is SOHC Vtec accord Motor
You can Run K20A3 pistons in this motor
86mm bore stock

H22 head will bolt up to this making the illusive G23. You would use the wiring harness that is in your current car, and modify to work with what you have.

An G23 using F23 complete bottom end and H22 head. Will get you 8.87-1 Compression

If you use K20 pistons. 10.37-1

[UpSideDownDesi]

how reliable is this g23 motor? and HP for N/A version?

[dabuilding]

this is sick i might save up and do it but im going to keep saving and run some boost

[mirz833]

have this set set up rigth now love it wiring harness used obd1

got some video:goodjob: :goodjob: :goodjob: if u interested ill share

[EmminoDaGreat]

I personally wouldn't waste my time, My all stock F23 makes 265whp @9psi.
Im sure there would be gains from a real vtec head. But is it worth the effort? If you have the parts I am sure it would make some decent power.

[dabuilding]

dude post the vids man i wanna see lemme know some info im interested how much did it cost and tell me everything man i wanna know about this engine

[mirz833]

parts you need: da axles, accord midshaft, block, water pipe , h22 head water pipe, hasport mounts, slim fan, tranny, h22 headers,arp head studs and some other shit that u can find on junk yard cost me just under $1600 but i had some parts. Ill get some more videos when i get to my old comp but here is two that i found on youtube i was told that the other car had k swap dont no which one im in the sol o yea if u do it get lsd tranny

[dabuilding]

damn that shit is quick yo do u got any build pics, daylight vids, or anything else

[x Resilience]

damn that shit is quick yo do u got any build pics, daylight vids, or anything else

He also spanked a S2000 by 3-5 cars.

[dabuilding]

damn not bad

[UpSideDownDesi]

worth the n/a effort to put it back in a 02 accord?

[mirz833]

He also spanked a S2000 by 3-5 cars.
i could have killed that s2k 10 cars if i wanted to but d reason i didnt bc i told him i had b18 or some shit like that

[mirz833]

damn that shit is quick yo do u got any build pics, daylight vids, or anything else
when i get to my old com ill get some but im telling you its quick for na

[dabuilding]

thats a sick sol im not much of an N/A guy i love boost but thats sick man hook me up if u know anyone sellin some more stuff like that i wanna build one myself

[x Resilience]

thats a sick sol im not much of an N/A guy i love boost but thats sick man hook me up if u know anyone sellin some more stuff like that i wanna build one myself

You should, def one of the sickest N/A builds.

[dabuilding]

well if i can find it all fo a good deal ill jump right on it and eventually build it even sicker with some major boost i found a whole f23 engine on ebay for 500 but i just dont have the money

[RL...]

it was a badass article

[dabuilding]

so if i run a b series tranny ill have to buy a mount right
can i just use an f23 motor

[x Resilience]

so if i run a b series tranny ill have to buy a mount right
can i just use an f23 motor

I'm no Honda guy so I might be wrong but if you wanted to run a lets say b16 tranny you would need to do the same as you would if you were doing H2B.

[dabuilding]

o damn i just caught somethin i meant to say can i just use an f23 tranny insted of f23 motor lol

[mirz833]

use h22 f23 long gears o here is my new vid from today
http://www.youtube.com/watch?v=arZg6Sy4vFQ

[dabuilding]

MOAR!!!!! lol so i could use the f23 tranny in my civic right

[mirz833]

yes

[dabuilding]

sweet now all i gotta do is do this on the low lol im a broke man so hey do u have any build pics or anything

[mirz833]

these setups have been around for a while (at least 5 years). They have a reputation for having reliability issues. Don't get me wrong, it has been done successfully by a few, but it is very rare to get more than 15-20k miles out of one of these engines. Why not just buy a H22A? By the time you get done building the engine you will have twice as much money tied up in it... If you want something reliable, find a jdm F20B (DOHC VTEC). It's pretty much a destroked H22A type S. It has 200hp, and with the right tune these things make damn good power. Also, it has steel sleeves instead of FRM like the H22A. If I was still into honda's I would definitely go with a F20B or H22A over the "G23"...

[mirz833]

tx well if you need any help just askk:goodjob: just found this on my ph having fun in my hoodhttp://www.youtube.com/watch?v=UX4oE4zCgKA

well for 2 reasons
1. its not that expensive to build i priced one on ebay for under 1200
2.it makes around 240 hp

[dabuilding]

ok i might just do that i just got to keep my eye open for good deals and start savin my money if u see any part of it on the low let me know

[allmotoronly]

well for 2 reasons

I highly doubt it will make 240 flywheel hp without spending a lot of money on aftermarket cams/intake manifold/chipped ecu/tune...

I've had a built H22A type S with cams, intake manifold, throttle body and a full exhaust system that probably only made close to 240-250 flywheel hp, or around 200-210whp...

$1200 will only buy the bare minumum parts. With stock H22A cams you will never get close to 240hp even at the flywheel.

[allmotoronly]

It's just like when people put a H22A head on a H23 block... without higher compression pistons they don't even make as much HP as a stock H22A...

[allmotoronly]

Oh, and for $900 you can buy a complete F20B engine

$1500 will buy you a blue top H23A DOHC VTEC engine

And you can find just a plain H22A long block for around $800...

[speedminded]

well for 2 reasons
1. its not that expensive to build i priced one on ebay for under 1200
2.it makes around 240 hpYou will not get 240bhp.

Race team I crew[ed] for ran a Frankenstein h22/23 provided by Honda with about 260bhp in their Speedvision World Challenge car. That was with a $1k+ header, full standalone, etc. That prelude would do 151mph at Road Atlanta, lol.

They built a B20z bored out with RSX type-S pistons and b-series connecting rods (GS-R?) and a b16 head with stage2 Skunk2 internals. Running Hondata and a SMSP header it made 207whp and the torque maxed out at 4,500rpm's and was practically level all the way to 8k @ 145-150ft-lbs. I posted dyno vids of it on here like 4 years ago.

Get an H22 VTEC. Long block and transmission $1,500-1,800 or less.

Thank you.

You will be lucky to even make 180 flywheel hp with the g23 setup without very expensive aftermarket parts...

ok i read it wrong with just the bare g23 motor with k20 pistons it makes 200+whp if u dont believe me dont argue on here go look at page 92 of the febuary import tuner and it makes 260+whp with the shit they built it with

Think about that the fuck you are saying. There's no way in hell you can get 200whp out of a "bare" g23 motor with just K20 pistons. The JDM H22A type S has the same compression ratio as the "G23" with K20 pistons would have, and has better cams, larger throttle body, etc. Even it only makes around 185-190whp, on a good day!

Oh and by the way, a stock F23 bottom end is NOT built to handle the extra RPM required to even make use of the H22A head.

[allmotoronly]

ok i dont care wat u have to argue about im going by there build and it was 200whp not crank this is strait out of the magazine so argue with them

Whatever kid. It's a horrendous waste of time and money. If you want something reliable just get a h22a or f20b. You will make more power and won't have reliability issues. But don't listen to those of us who have actually done it, listen to some ricer magazine.

[Nang]

i dont believe its a waste but hey thats me

[allmotoronly]

i dont believe its a waste but hey thats me

How is it not a waste? You will spend way more money on a setup that makes less power than a stock h22a. Just buy a h22a, get a set of skunk 2 pro 2 cams, a euro r intake mani and a good header. It will be much more reliable and make better power.

[dabuilding]

well im not saying u guys are wrong ill take it all into consideration i just dont have alot of money u know times are hard and i want a setup i can afford and have a good bit of power thanx for all the input but wat about mirz who does have one and is still driving it

[allmotoronly]

If you don't have a lot of money, why waste money on the G23? Stop kidding yourself. You are not going to be able to build it for less than $1500... For $1500 you can buy a complete H22A which will make more power and be far more reliable.

If you wanted to build a "G23" to be able to handle the extra RPM's required to take advantage of the DOHC VTEC head, you are going to have to completely tear the bottom end down and rebuild using aftermarket "Race" bearings and other componants. A F23 bottom end was not designed to turn 8K+ rpm. By the time you pay a machine shop to do all the prep work to the block, install new bearings, install K20A pistons, you will have at least $600 in the bottom end alone, not even counting the price of the block. The H22A head is going to set you back about $400. Then (if you aren't a dumbass) you are going to want to have it prepped by a machine shop also (check tolerances, etc). Throw in a few hundred more dollars for all the other little shit involved, plus paying someone to assemble the engine, and now you are getting close to $1500.

JUST BUY A DAMN H22A. Think about it. How can a stock parts "G23" make more power than a H22A? Even if you use the K20A pistons in the G23 it will still only have close to the same compression ratio as a stock H22A. It's reall not worth the time and money. Buy a H22A, throw a set of cams in it, a good header, euro R intake mani, a good tune, and call it a day. That should put you over 200whp, and it will last forever if you take care of it.

[speedminded]

somebody cant read 250....wat! i said 200
ok i dont care wat u have to argue about im going by there build and it was 200whp not crank this is strait out of the magazine so argue with themDo you even know the difference between crank horsepower (bhp) and wheel horsepower (whp)???

Plus do you know how much climate effects a dyno? In the perfect near zero humidity of California the numbers and even drag times are vastly better.

also are g23's heavy just like the h22s?What makes you think an H22 is heavy?

[Nang]

What makes you think an H22 is heavy?

because he read it somewhere i bet

[nreggie454]

also are g23's heavy just like the h22s?

Apparently, the H22 is only about 35 pounds heavier than a B series, but with ~30 more ft/lbs of torque. Totally worth it IMO.

Just go with the H22A. The G23 sounds like a less researched LS/VTEC (which pop all the time), so I wouldn't be too sure about its reliability.

because he read it somewhere i bet :cheers:
