I'd like to do a H22A engine swap, only because I no longer have reverse in my transmission (but oddly enough have learned to live without it). So I may as well make out and buy a engine coupled with its tranny. Also, I've always wanted a VTEC power plant.
I may be able to sell the H23A1 after the swap to compensate the expenses. Believe me, if I throw in a H22, there will be a future for that engine.
However, with my H23A1, a T3 turbo can make gains of up to 100 HP. And as a engine, mine still has some life in it.
Perhaps even a supercharger??? I've heard of Jackson Racing and Vortech superchargers modified and placed on 4th gens.
H22 swap: You could probably get a lower milage H22 in there for under $3000, with new belts and water pump before installation. Factor in about another $500 if you cant do it in your driveway.
Turbocharge: In order to RELIABLY boost the H23 to the levels that you stated, you will probably need to spend a good deal more than you think. You are also going to need to do a TON of research if you want to do it right. Engine and fuel managment, stronger internals, dyno tuning, tranny work. . .it's gonna add up fast.
Supercharge: Keep dreaming buddy. There is currently only ONE blown 4th gen Prelude in existance (to my knowledge, anyhow). No "bolt-on" kits are available now, and I wouldnt wait by the phone for Endyne to call.
hugo boss, Hondas and turbos are not made for each other. If they are, they would come with stock turbos. Also h22 + turbo was not one of his options . I'm just being a smart ass.
Redline, how the hell do you park without the reverse then? It all depends on what your car is for. If it's a daily driver, I'd just drop in the H22 and not deal with all the headaches of the turbo.
Anything else other than a daily driver, I'd build up the h23, if money isn't a problem for you. VTEC is nice, but turbo's better. You WILL run into some problems with the turbo, but you'll be much faster than a stock h22. You can pick up a used SI tranny for like $300-500. My .02.
I say turbo. For 3000 you are not gonna be that much faster. If you just want you car a little faster and run with out worries then get a h22. You can though get about 240whp on stock internals with about 9 psi of boost. There are numerous people that have done so. You will have to spend a lot more to put in a h22 and try to get it to those numbers.
get the swap, im very pleased with mine, i went from 15.7 @ 88 to 14.3 @ 98, thats a big damn diff in the same car, and you wont have the worries of turbo problems, BTW putting the vtec motor in an Si prelude is soooo rediculously easy its not even funny, you can find full swaps for under 2400, which will also give you a newer tranny....plus its a nice motor..peace
Great, this is just the kind of feedback I wanted.
First, yes my transmission hasn't had reverse since I missed 3rd one day. There's a good thread about missing third and losing reverse floating around. So to park at home, I have a parallel parking space on a hill, so I just roll back. And when I'm out, I'm usually at a mall, so I just drive into a space that I can drive forward out of. Mess around if your really curious, by just leaving your car in neutral, you become aware of just the slightest incline to help ya not have to push.
Chicks dig pushing the car, it gives it that stock car aura..., j/k
Anyway, I have a friend who built a turbo around his H23, and has pressured me to do the same. Granted the car is quick, but he's had alot of down time on his car, and it was all sorts of expensive.
I'm leaning towards a swap.
Are there any good sites for engines? And whats the price range on a good H22. Which engine code should I get? And how much should I pay for installation?
Personally I would go wtih a turbo. If you sepnd about 2500-3500 on a turbo kit and run low boost you can match an h22 in both reliability and performance. I dont see any reason why running 3-4 psi (very much on the safe side) on a stock h23 (assuming the motor has good compression) would giive you any probvlems, even if you just run an 'out of the box' kit like drag (which you can get for under 3 grand). With this you can probably put out about the same (if not a bit more) than an h22. At the track though, you could still run 5-7 psi (still on the safe side). This should give you a definately 15-30 hp advantage over an h22 at the flywheel. Furthermore, you will already have the turbo kit there so in the future when you want to upgrade you will be one step ahead of the game. The biggest problems with turbo setups is when people boost alot. Stock internals can usually handle around 7-9psi, but when you boost 9-11 you are pushing it and you have problems due to lack of full and too high compression. I dont see any potential problems that would occur on a motor boosted always under 7psi, especially if you keep 5psi as the maximum amount. Obviously this is assuming everything is installed properly (also a common problem of turbos routes out of poor installation).
Also dont forget that with a turbo h23 you will have more lowend torque than an h22, because you will still benefit from an h23's longer stroke. This is an advantage for low-rpm driving when you arent in boost (3-4k) or VTEC (5-6k).
Feel free to point out any flaws in my logic here.

hey guys, i was thinking about doing something close to what redline is doing. i want to swap in a h22a and then turbo it. is that a wise decision or what? let me know what you guys think about that

Waste of money. You will be better off taking that 2000 you were gooing to spend on the h22 and but stong internals in the h23 so you can crank up the boost.

Definately. For $2000 you can easily get a tuned hondata, shot-peened rods and low compression pistons (assuming you do your own labor) and just save up for some sleeves. With this setup you should have no problem running 12-15 psi safely. You'd be better off heading over to the FI forum for more technical, but with the extra $2000 on top of a turbo you can make some crazy power, much more than you will gain by having vtec.
Personally I would rather a well-tuned h23 than a well-tuned h22 (lets just say the make the same HP), because the 2.3 has a longer stroke so you will have a bit more torque down-low while the turbo is lagging.
Just my 2 cents.

Turbo was the greatest thing I have ever done. It is like a whole new car. I can't even describe the feeling of boosting (especially the first time). As far as headaches it depends on how you build your engine and how many pounds you want and how you treat your car. I have only had a few minor problems and I never regret boosting. I had the option of doing a H22 swap or boost same as you and can't tell you enough how much I love turbo. Don't listen to the people who have never had boost about all the problems we have cause it isn't that bad just know what you have and how to read your car. You won't have problems if you listen to what your gauges are telling you Jus thought I would express my opinion on the matter.
i didnt once see mentioned building the h23 for juice, 1) you can build up the h23 to run higher compression by swapping in different pistons or milling the head or both, while doing that, make sure they can handle the temperatures the juice will cause. and just enjoy it when you want to. 2) show off to them h22 guys what bigger displacement is all about. i know when im done stroking my motor and jucing it, im gonna love whipping up on all those vtec boys and girls(not gonna be sexist) out there. juice is cheaper and you dont have to worry about it always being there, just when u want it to be.
