Ls/Vtec. Posible or not????

#1. Will H22 Head fit on B18b Ls Engine or biger then Gs-R or IT-R head?
If it works should go forit or not? I'm asking because i was thinking to do H22 swap but read forums and found out that wont be easy fit so i remembered that one guy said that he got 97+ prelude engine with damage to the botom so i thought mibe good deal for head or whole engine.
#2. And whats better idea H22 swap or Ls/Vtec?:smooch: How much Ls/Vtec wil cost not inkluding other parts?

LS/Vtec is a very complicated hybrid engine to get with reliability. If it's built right it will last a long time, if it's built poorly/cheaply, it will not last long at all. LS/Vtec is a great way to create power without buying a type R b18c5 or a Civic Type R b16 engine. LS/Vtec is very possible and many people do it. I have a friend building a turbo LS/Vtec engine right now.
Most people who build the LS/Vtec engines use the b18b block and the b16a head. h22 and b18 have NOTHING in common. If you want to do the h22 swap, DONT. It doesn't create much power. You are spending a lot less for an h22 swap, and getting exactly that, a lot less.
The power with LS/Vtec comes from the high compression created by the hybrid setup.
If you are looking for how much it is going to cost you, you must first look at how you want to build it. If you want a very powerful LS/Vtec and have the money, you can spend 7-8 grand EASILY. If you are looking for a cheap/fast/temporary setup, you can spend as little as 2000 just to get a b16 head thrown on your b18 block. Labor not included in any of this. I thought about doing it, but I would have done it myself with the help of a friend.
All questions can be answered on these websites. (www.g2ic.com or www.honda-tech.com) There are posts upon posts upon posts on LS/Vtec and if you do a forum search, you will definitely find people with the same exact questions as yourself.
Good luck with the swap if you do it, just get ready for the power behind it! :grinyes:

Sorry to be negative, but that was a horrible response to his question. An H22a swap doesn't create much power? It gives you more power than swapping in an ITR engine, which you seem to think is pretty good (since you compared it to the ls/vtec). Sounds like you're giving this info based on BS that you've read online, rather than real knowledge. And the cost of the h22a swap (including the correct axles, engine, ecu, tranny, and aftermarket mount kit) you'll spend right around the same amount of $ as if you were buying an ITR swap. And you don't need to spend 7-8 thousand to do an LS/vtec, you can do it for much cheaper than that, especially if you shop around for parts (like the head).

But to the original poster... B-series with B-series and H-series with H-series, there's no interchangability between the 2 different engine series. And which is better, it based on personal choice. There is no better engine over another.

So wich engine will be more powerful IT-R engine or Ls/Vtec?
I'm thinking to put turbo so what would be better for me to rebild Ls engine or to put IT-R engine and turbo it? I heard that Vtec doent work well with turbo is that true?

I'm not going to start a fight, cuz it isn't worth it. The h22a puts out 190hp stock. The b18c5 puts out 197hp. If you are going to swap in an h22, with the correct parts as he listed above, it's more work than it should be. If it's going to cost the same thing, as stated above, why not just get a b18c5 motor from a type r? They are great when boosted(though it is said that the b18c1 is better in some aspects), and you will get a lot more heads to turn with a b18c5 or ls/vtec engine. It all depends on what you are going for. What do you want to get out of this? What kinda horsepower are you looking for? is it going to be a daily driver or your second vehicle?
I may get flamed for stating my opinion, but so be it.

I'm not trying to flame you or start a fight, just correct incorrect info that you gave. There are other things other than horsepower that need to be thought about, especially torque. The H22a has far more torque (at least by Honda/Acura standards) than the ITR engine. And with jdm vs jdm engine, there isn't much difference in hp anyways. The only things, other than having to buy other parts like aftermarket mounts and a non-stock combo of axles, that you need to do for the h22a swap is some minor cutting and wiring. It definently is more work than just swapping in a B-series engine, but for anyone who has done the swap; it's well worth it.

But I do agree, there are a lot of things that need to be answered before selecting which engine to go with; like the questions you asked. Some more would be, what car is this going into, and do you have to pass emissions testing? What kind of realistic budget do you have for this project, and what kind of down time can you handle to get this swap done and working correctly?

Im thinking on upgrading my Ls engine so i dont have to spend all the money on other engine and then parts for is so i'm thinking to spend some money for inside parts and then put turbo on it in my plans im thinking to run up to 13psi . Can you guys give me some info wat do i need to chenge on/in the engine to run that much boost. and how much would all that part will cost me not including turbo. onother thing do i have to chane transmishion if i do which one would be the best choise? Thanks for your help.
