go to superhonda.com(sorry guys, but there is some info there on this). a guy there did one. it turned into quite a job, but he did put together everything needed to do it. it wont be that cheap, if it was me i'd spend a little more money and get a turbo, plus you'll have more power.

Ahh I asked the same thing. And I was strictly told that it was not worth it. Not only is it expensive as hell but you will spend hundreds on hours tinkering with the engine to get her into running condition. I was told it's a job you don't wanna try....but that's just my 2 cents!
PS. Why do u want to do that? Is it that whole silver/non v-tec thing that I am pondering upon?

. itll be cool to add some power in a way not many people think to. im just wondering about the cost, i know theres a lot of pieces involved

. i feel it is a safer mod (4 the engine) than a turbo!

A guy named Toddman did it on SHO. He is the only one I can think of that actually drives it. It has been a while so I don't know what he is currently up to.
The dyno you guys are talking about was done by atomic at www.importreview.com. Just dig around and you'll find it. It has a couple bolt ons, but still impressive.
I was thinking about doing this, but there is no one in my area that has conquered this.
A ballpark estimate would be 3 to 4 thousand; if you want it done right.

Actually it had no bolt ons, it's stock except for type S pistons and a VTEC head. For all that work I don't think it was really all that impressive.

One think to keep in mind, if it's strictly for drag that's fine. But taking curves would be

How are you going to get oversteer out of a head swap. granted the VTEC head (and assorted wiring/sensors/etc.) probably weighs more but I doubt it weighs enough to throw off the handling that much. It's not like dropping a H22A into a civic HB.<font face="Verdana, Arial" size="2">Originally posted by jbx:

now i feel like im getting talked out of swapping! i havent put a header on it yet b/c i was waiting. now i think a header will just have to do. ive heard the best about DC's SS. i dont want my sh!t to crack. the color change doesnt bother me...ill work on keeping it clean. would you all suggest something else?? let me know...summer is coming and i won't wanna be slow in the nice weather.

You should be talked out of it b/c:
- Look at honest dynos; an H23 with an H22 head and *similar* mods as a straight H22 engine make about the same power- the extra .1L displacement doesn't make that much difference.
- Oil sprayers. The H23 was NOT equipped with the piston oil sprayers the H22 was. H23/VTEC hybrids are notorious for failing early. The VTEC redline and oil-hungry nature spell death for the non-sprayed H23. On top of it, the H22 sprayers don't clear the crank on the H23, you'll have to cusom fab one or get in the habit of replacing your block when you punch a hole in it.
The H23 swap, while it might be attractive b/c it's "different" or cheap, is a bad idea in the long run. Get a used H22 and build that up if you want more power.
You're right Gabe, my fault. I was reading something else at the same time.
Yeah, .1 liter is alright if you are going all out crazy monster motor, but for all reasonable purposes, it is overkill.
Sorry we have all talked you out of it, but it is for the better.
There were a bunch of guys that have started to try it but gave up.
