H23 swap into CB7

[SE_DynamiK]

Hey everybody. Im about to buy a full H23 swap from a 94prelude and i had a few questions.

1. What all do i exactly need for the swap? Im getting a deal on the entire H23 block and head, H23 tranny, P14 ecu, cv axles...basically, i have availability to everything under the hood but i just want to know what i do and dont need.
2. Are the engine and transmission a direct bolt in?
3. What are the pros/cons of an H23 block with H22 head compared to a full h22 engine and block?
4. What all would i need for the H22 head swap?

The reason i want to do this swap is because i just had major body work done and painted my car and my H22 fund went down the drain. Then i started reading up on the H23 and found that you could put the H22 head on the H23 and make it a 2.3 VTEC, which sounds quite pleasant.

I figured this would be a nice alternative in the meantime while i rebuild my H22 fund, or maybe just swap in an H22 transmission...? (input please)

Thanks,
Kevin.

use your axles and everything things should bolt right in, you just have to add a knock sensor also if your going to do the vtec swap i suggest you go ahead and add the wire for vtec do and you will be set. if you do the head swap your compression will go to 9 to 1 or so, so you will lose power. I would recommend also buying some malh pistons so you can bump up the compression and you don't have to put to cyc walls in. I have an h23 is nice but its no H22, but I plan on doing an H23 swap later this year or early next year.

Hey, yea you can swap it in with ease really. Sounds like your on the right track with ideas and plans. About swapping the head, it can be done but I wouldn't recommened it. Keep the h23 trans thats mated with the block unless something is wrong with it. But just replacing a good trans with the h22 trans is a waste of money and time.

so all that i need for the engine swap is the block, tranny, ecu, and knock sensor?
and all i need for the head swap is the H22 vtec head, vtec solenoid, and p13 ecu...correct?
and although ill be losing power and compression by swapping in the h22 head, wont the addition of vtec alone make up for it? the way i look at it is a vtec h23 is better than a non-vtec h23. and plus i just want vtec soo bad lol.

[Smiley_cb7]

No you don't need a knock sensor just for swapping the h23. Do you really want a good, quality engine swap with less problems than possible? If so, either do the initial swap idea of an h23, or the h22a. The head swap thing is not all that good of an idea to me, just IMO. And no, you need more parts than what you listed. The oil distribution throughout the engine becomes a problem when doing this head swap, unless you know what your doing. If you have access to the H23 get that, swap it in. If you want vtec, H22. Just remember that there are a good variety of engines to choose from besides he H22.

Thanks for the help guys, muchh appreciated
Hopefully i can get pics of my car up as soon as its all back together

oh and one more question:
are the majority of h22 parts cross compatible with the h23 (i.e. throttle body, intake manifold, fpr, fuel rail...etc.)
if so, what should i upgrade?

a lot of of parts can be crossed from the h23 h22 and the f22, I suggest you do some more research, you have a lot of idea but a search would help. The H23 vtec swap can be done, but if you 1/2 ass it, your send your days going why wont it run. H F D B throttle body's will all work the bolt pattern hasn't changed much in forever. I think scrolling threw the members rides sections would give you an idea of what some of your ideas will take. Also go join hondatech they have some crazy people on there and who can help you a lot to, to date I don't know anyone who has done the H23/22 vtec swap on this site.

maybe i can be the first to try the hybrid out
jk i guess ill probably just stay full h23 until i eventually go h22 then
thanks for the help

Turbo the h23 wouldn't be too hard to have 200 horsepower.

[SE_DynamiK]

yeah i was just thinking about that, but i dont really want to go turbo.
N/A is less hassle imo

Ok so im going to pick everything up this weekend for the swap. I forgot to mention that im also doing the auto --> manual swap, so what else would i need? (i.e. mounts, etc...)
also, is there anything else i should know about, like electrical work involved?
i remember someone posting the wiring information about the h22 swap, such as which wires you have to connect together at the shifter to make it stay in park and the two wires you have to run from the top of the transmission in order for the reverse lights to work...is this what i am going to have to do also?
and if it is, is it pretty much the same as wiring the h22?
i need to know everything involved so i dont miss anything during the swap and eff myself over (which im pretty good at doing ).

Thanks,
Kevin
