h23 vtec
i was wondering what you guys think of an h23 vtec in my 97-01 prelude. i know that if i do it right it wont have any problems because a friend of mine has it done in a 92-96 prelude and it pulls nicely...just wondering because i havent heard of anyone doing this swap in a 5th gen

Re: h23 vtec (Hatchbizzack)
just if you wanna do that go get your motor stroked to a 2.6l by a machine shop it will cost aboutthe same since you got the h22 just cost you a pretty penny but it will be built right. half the people who do the h23 vtec do it as cheap as possible and then it blows. my whole opinion on the matter if you are going to do anything to your motor you might as well do it right.

Re: h23 vtec (H1PNOT1C PRELUDE)
That was a friend under my username, but I can elaborate a little more on the subject...
The car he is talking about (under my username) is a 92 Prelude Si with an h22 head swap. The car does feel pretty quick, but not too many people try and test him knowing that he has the frankenstein done.
I'm confused because some people say that it isn't worth it, but with the h23/vtec swap, he pulls 5th gen Lude's by multiple cars from any speed (3-4 cars). The mods are i/h/e clutch and flywheel. Still using the h23 drivetrain. (tranny,axles, ect)
But getting the whole swap for $300 max, I don't blame him for doing it either

Re: h23 vtec (H_doubledeuce_A1)
well guys to add i have a 97 honda accord lx that did have a jdm h22a type sh swap (stay away from that motor trust me )and it was all good until i hydrolocked the engine(drank water) and i was thinkin about gettting another h22a put in when my brother and i came across a h23 from a 93 prelude si auto ,hmmmm so i heard about the ls/vtec swap and thought how hard could the h23 vtec swap be same internals which now i know are different but able to be married together so right now i have the 2000 h22a head on this h23a1 block trying to bring a frankenstein h23vtec to life and i am using a gsr obd1 ecu plan on getting the oil squirters for the bottom end crank and some h22a pistons and maybe cams and leave it at that but i have heard numbers like 220 to the crank and 186 to the wheels not bad at all can't wait to get it alive and running thinking about a jackson racing s/c we will see

Hey Everyone,
I'm a new-comer to the automotive game, but am eager to learn as much as possible. A friend and I were talk about engines the other day, we were talking about his soon to be Integra "Ls/VTEC"... When he mentioned the H23A/VTEC or what he called the "Si/VTEC". I just happen to have a '92 Honda Prelude Si...and am very interested in this frankenstein engine. What exactly would I need to do to transform my simple H23A in a VTEC monster? Thanks!

first things first, drain all the oil in your H23. Then take it on the highway, drive the **** out of it till you fry all the internals. Then buy an H22, from there you just swap the engines and you should have a VTEC monster :D hope this helps!
hahahaha, j/j.
Anyone who has done this swap and said it's "easy and cheap" is lying to you and their engine will blow up sooner or later.
Those who have done it right, will tell you it takes time and money and it will run nice after a lot of work, but it's not an "easy cheap" thing to do. They lie.

Re: h23 vtec (the_eyecon)
^^^^^^^ definitely agree. I've heard a good 80% of these creations blow up. It'll take a good long time to get it right, but if u happen to be one of those few who does do it correctly, it's pretty sweet.

Re: h23 vtec (5hif7)
as long as the motor is built correctly there shouldnt be any problems. the guy i know that has the motor.....his is running perfect, however the only downfall is that you cant rev as high, but other than that i dont really see anything wrong with it because im sure with a lil more mods you would be able to rev just as much. the h23 vtec guy is only taking his to 7200 when he shifts, but i take mine to 8000

How many people have studied all the h23vtec's with great interest and found them to be blown by something OTHER Than over revving ??
I've yet to hear of any. In fact, I know a person who's put together a number of them and drove one himself and said so long as you aren't surpassing 7200 rpms and trying to rev high they will last fine.
As a daily ride the H23 crank w/ new bearrings and being balanced / knife edged even .. should last a good long time to stroke an H22 engine so long as you aren't over revvin the bish.
Think a bout it ... spin your H23 non-vtec to 7000rpm .. I did it once at over 100mph (by accident
) but the engine was fine .. I've heard others saying it was fine also under the same circumstance..
As a daily driver where you won't be vtecing to 7200rpm and hardly vtecing, the engine will be great w/ the low end torque.. and when you want to embarass a b series ricer .. the high end is there above 55 if you want it.
Though im not speaking of my personal experience... Satan, what did yours blow at ?? 7800-8000 rpm ?? ..

I am lost. Why is revving to a max of 7200 rpms a bad thing?? Does anyone have dynos or proof that the car is making power up that high??
I am in the stages of prepping my H23 bottomend to make it into an H23 VTEC.

Re: h23 vtec (AndyD)
A lot of what I'm reading is "if you prep the bottom end right" which is MORE MONEY. Honestly for a good build of an H23VTEC you can buy and H22 AND some mods. I mean really you figure...
H22 head 400 bucks
misc - 500 bucks
work on internals - 300-400 bucks
time you won't have a car - two weeks or so?
vs.
2500 for an H22a and about a day or two to swap the engine.
hmm... h22 sounds a ton better to me, not to mention there is a lot more out there for an H22..it's all on you though...I dont' believe in the H23vtec.

After seeing these dynoplots http://www.importreview.com/d_2.3.html I think im going to go for a direct H22 swap and call it a day .. there really isn't much more tq and power added compared to a modded H22 ..

H22A7 is an Accord Type-R, not a Euro-R
My 2 cents on the subject.
My h23 VTEC made 206whp/161wtq
My 2.3L H22a made 214whp/167wtq
If you build it right you don't need to bother with an H23 crank, and your motor wil last longer.
