sup guys, i have a 2001 h23a blue top, i made a big mistake in changing the factory intake manifold the engine brought to the us one. both look the same but there not the same.the gaskets don't match, and the injectors don't work properly with the us manifold, please were can i get this gasket.

 

so ur looking for an h23 im gasket? you can use a h22 one and h22 injectors

 

yea i know, iwanted to go back to the jdm manifold but just found out that the problem now is the injectors im using, sense i could not use the h23a injectors i poped in the ex accord injectors from the f22 engine my accord had,and guess what? now im running lean,crap crap crap. i put on a air and fuel gauge and that thing don't go to rich even if it wanted too.

 

i just orderd the injectors from a h22a1 hope this evens out the problem

 

Why is it that you can't use the H23A injectors? I bet they are larger than the ones you ordered for the H22A1.

 

the thing is that i had changed the intake manifold to the us one and at the same time put in the hondata gasket, but it dind't work with the h23 injectors because they need air,the us manifold is not compatible with the h23 manifold, it has a air hole in each injector port and the us don't have this holes so the engine gets flooded with gas.

 

right now im running it with the f22 vtec injectors and it sucks.

 

That is called the Fuel Injection Air Control System (FIA), the 94-95 F22B1 has those holes. As well as one of the F23s. All you need to do is plug the holes feeding the injector with a bit of silicon/JB weld.

Are the H23 injectors low or high impedance?

The F22B1 injectors are only 240cc low impedance, I bet those H23 VTEC injectors are 345cc high impedance.

 

well the thing is that if i seal those holes the injectors send more gas, i put those injectors in the us manifold, i put a full tank of gas on friday and by monday it was empty lol, so i put on the accord injectors for now.

 

What ECU are you currently running?

The H23 injectors shouldn't inject more fuel if you block off the FIA. If your O2 sensor is working properly it will keep your AFRs in the proper range. It shouldn't add more fuel for no reason.

As for your fuel mileage, I'm pretty sure that's what happens when you drive an 2.3L DOHC VTEC with 290cc-345cc injectors without a proper tune. You shouldn't be swapping injectors back and forth without making sure they are the proper impedance and flow rate for the engine and engine management.

 

well i thought that if the injectors don't have that air feed they will dump more gas, and about the ecu i have a p28 with prelude basemaps. the car was running fine with the ecu,all this started happening when i switch the intake manifolds. if i was to find the same gasket from factory that bellongs to that motor trust me i'll put everything back to factory.

 

you know i was looking at the intakemanifold gasket from a 98 f23 and it almost looks the same but im going to take the manifold and se if they match?

 

Yup......The 98 Accord EX 4dr has the FIA.



The 94-95 Ex F22B1 also has those holes as well. I'm pretty sure they are the same pattern.



Sorry reading owns me. I thought you were looking to get rid of the FIA. Just looked at your original post and you are looking for a replacement gasket..... Sorry about the big run around.

 

no need to appologize just miss understood but when i did the swap i tryed to put the f22 intake manifold on and did not fit,is thef22b1 diferent from the f22 vtec?

 

No they are the same layout. The only difference between the B1 & B2 are the FIA holes.

The H23 VTEC head must be the same design as the H22 head. You may have to take an H22 gasket and cut/drill the FIA holes in it......

 

But that's if I use the factory gasket because right now I have the plastic one they use for racing and the problem with that one is that the shape that it has is just to cover the head inserts. That's y I can't put back the stock manifold. If u see the gasket pix u showed me and comepare it with a h22 gasket u will see what I'm talking about.

 

This engines Are very complicated if u ask me lol

 

well over the weekend i bought the 98 accord f23 intake gasket and it does not match. the h23a one is a lot bigger.

 

i wish i new somebody in europe,they can realy help me with this engine sence its imported over there. they should know what part i need. lol

 

well i bought some gasket paper,i guess i'll have to make the factory gasket to use the injectors and the factory manifold.question,is the h22a4 injectors the same as the h22a1 injectors or the h22a injectors?

 

Nope! The H22A4 injectors are 290cc high impedance and the H22A/A1 are 345cc low impedance.

 

ok thanks I knew there was something rong,any way almost done with the stock gasket,ill see if it pulls good.can a tune p28 get the program eraced by taking it off alot or something, or by receting it alot?because im thinking on re-tunning it.

 

Stranger things have happened with chipped ECU's however, if it was erased it probably wouldn't work and it would throw a CEL. Personally I have never had any issues with ECU's loosing a tune (knocks on wood!) I have had ECU's pulled in and out numerous times, thrown around and dropped still keep a tune.

What software are you using?

 

ok man thanks a lot,well i put the intake manifold today and it feels alot better than the us intake manifold. to all those people out there dont ever change the intake manifold on a h23a vtec engine, u dont need more than that i asure u.

i just got a h motor myself that im going to put in 92 96 Honda Prelude Accord Engine Swap JDM H22A OBD-1
ENGINE + 5-SPEED TRANNY + ECU + SHIFTER CABLE+DOWN PIPE i paid 1400 on ebay but i want to get a turbo kit and that hondata before it goes in do you live in pa you check it out my last car was a jetta with sds stand alone engine management t3/t4 garrett turbo stright pipe exhaust supercharger cam i put 11000 into the car then a tree fell on it wtf but i raced some kid with a turbo vtec and he ate me up so i will do a honda up to the max i just rebuilt my f22b1 motor just cause im retarted i just got so much to do but love working on cars well enough blabla bla i hope that link and phone number helps you if not i know another place you can get it from

The H23 was an increased-stroke, non-VTEC version of the H22, used in Japan, North America, and Europe. It shared the same Fiber Reinforced Metal (FRM) cylinder wall liners with the H22.
