well....i was reading the other thread about the guy in the h23 that dyno'd his car and read a post by another member and instead of responding to his post in that thread i decided to make my own because i know it would have turned his thread into a totally different topic then comments about his dyno....so here goes.

that statement is what made me post this thread. i really dont understand why people say that. sure you can make it as fast as a vtec prelude - if you have all the boltons, maybe some pulleys and an ignition, yea, it might be as fast as a stock vtec. when people say things like cantdrive55 said they make it sound like the h22 and h23 are equally capable motors, which they are not. stock for stock you are up 30hp if you have a US model, and 37hp if you have a JDM model. with equivalent mods, that gap is not going to narrow. and about that guys dyno plot....he made 153hp and 150tq. if you look at his list of mods, it includes cams, which is the next rather large step if youre going NA. not to hurt you h23'ers egos too much but my friend just dyno'd in his 93 vtec and put down 187hp and 156tq. his mods are only a dryer tubing intake, greddy header, open exhaust, pulley, and a vafc. no cams or anything internal. so even with not-so-even mods, he is up 34hp. as ive seen yellowh23a say before, he has a lot of weight reduction done, which tells why his times are good for an si.
im not knockin the h23 at all, i used to have one and i liked it a lot - but i like vtec better. with almost the same mods, i ran .7 better with my h22 in. i used to not be a believer of vtec either....until i woke up and realized that the 30hp difference is just too hard to make up without some decent work.
please no flames - i just want to have a decent discussion on this topic!
I tend to agree. While the H23 is a great DOHC engine, the VTEC does make a big difference.
Case in point: My bud had an SR-4ws (Si4ws) and had never ridden in an SR-V (VTEC). I took him for a boot around town. 2 months later, JDM H22a swap. Nuff said. It's just a different beast.

i realize that but thats why i said i just wanted to hear everyones opinion.....just like everyone has their own opinion on AMD vs Inter....personally im an AMD kind of guy....but thats just me

p.s. - nice handle
hehe yeah I like yours too but since you're an AMD guy... I don't like you
im going to have to agree here, as an owner of both motors..in my Si with i/h/e i ran a best of 15.6 @ 88..granted i couldve gotten that time down maybe to like 15.4 at best...my H23 was a fun motor, and it beat alot of other cars, civic Sis, and hung with GSRs..however, i now have a JDM h22..and my times are over one full second faster, i beat cars now that used to whoop me badly, and in my opinion, as I mod my vtec, it makes bigger and bigger gains from the same mods, i believe this is due to the high cam profile, and in reality, the h22 is made for racing, its got better rod ratios for higher revving, oil suirters to keep the pistons cool, and an overall better oil delivery system than the h23, why do you think you see so many h23s with oil related faliures? when i go to the track there are always people coming up to me asking how my car is so fast, ect..the h22 will definately get my vote..peace
His cams are not that big of a deal. The are only regrinds so they have the same profile. They won't make that much power. Also he lacks a header. A header gives more gains for a h23 due the the ****tiness of the stock one. JDM h22's run much stronger than USDM ones. The gap in the hp seems the get smaller as more mods are put on. Also peak hp is not the only thing to consider, just because a car make 200hp for a second if it only makes 180 through most of the powerband it will be slower than a car with 190hp that makes that thoughout the whole powerband.
Bottom line is that a h22 is faster mod for mod but if you have a good condition h23 it is not worth swapping the a h22.
i've always been a h23 fan because when i bought my car, it was equipped.. i learned to live with it.. and i like it.. but i am definately looking at jdm h22 swap for sure...
I personally think they are both good but wether they choose to admit it or not every h23 owner wishes they had the power of VTEC. There are other certain things about our bigger VTEC brother that make things that much easier. Like the fact that I have not been able to find either a red or a CF valve cover for the H23, or a stroker kit, or perhaps the worst slap in the face of them all no JRSC.
true the H22 makes more power but the best thing about the H22 is the aftermarket products...I wish they made so much stuff for our H23 as they do the the 22...both are great lets face it, they are both HONDA, that really says a lot!!!

I used to be schizophrenic, but we're ok now...
I have an h23 and when the timing belt broke taking out all my valves I just planned on getting an h22. The extra hp with the JDM h22 would've been nice. But the cost of getting everything together (plus a new exhaust, cat., gauges, etc) is close to the 3k mark.
FuQ that, no way I am paying close to 3k to be .7 faster.
But in my quest to rebuild my h23 I realized that there isn't jack shiet in the aftermarket for the h23. I mean as far as internals, if a co. makes something for the 23 (like connecting rods, pistons) it's going to cost you an arm and a leg. And there isn't much, if any, made for the valvetrain either.
H22er's have it better, there a few companies that make connecting rods/pistons/etc. spawning a little pricing competition.
But who knows, I'm keeping my 23. It might be 20-30 hp less but Most of that difference is after 5200 rpm anyways. h23's are way underrated....

No 4th gens get the JRSC and could dig up a JR ad of one put on a h23. Also you can get a stroker kit for the h23.
there is a pic of JR supercharger with a h23 valve cover but it is a h22.
the only guy in the US with a supercharged 4gen, i know. in fact, he is about to install one on another 4gen and take it out to jackson racing to get it dyno'd.
he is also the only person i know that has a truely working jdm climate control that actually does all the functions correctly. oh, and he installed one on another persons lude too, so i guess there are 2 people with working ones!
Yeah, here I go again. I'm the guy he installed the climate control and as forbidden said, EVERYTHING workd properly and I am satisfied. I have already purchased the SC and am getting it put on in the next to weeks by CAZ. I hoping everything goes fine granted I have to drive a couple states away.

but back to the subject!.....
No it is a h23 with a supercharger on it. They were going to make one for a while then decided not to.
