Well after several weeks/months/years how it seems of problems with my car, i have decided to dump the h22 motor and put a h23 head on it. I have and agreed to do a little trade off with btleier...

This is what we plan to do, if you dont mind: people look over and see if there is anything you notice that may be a problem or something that will need to be added?

My Car
1996 Accord:
1996 H22a1 in it:

I have the h22a1 motor in my car.

I want to take the 92 Si H23 head and intake manifold from btleier and bolt it on.

I plan to block the vtec oil items in the block (is this a must? or just a precaution)

His h23 intake manifold is an obd1: (i know their is a difference with other manifolds, but do i need to look for an obd2 intake manifold, or can i get it to work ok?)

I will be running a 96 h23 ecu. I am assuming i can keep the exhaust manifold and everything else? Any ideas suggestions or problems? Pulleys, crank, pistons and block internals all going to be ok?


btleier project

He has the h23 motor from his '92 Si... he will be using that motor's h23 block with my 1997 h22 head. (head came from mikeylude) He plans to do a complete build of the h23 block (sleeving, aftermarket pistons, rods, etc), and building the h22 head (skunk2 internals), and eventually I will go turbo. From what i think, he needs to read and do the h23 vtec research.. he has pretty much a guide line to follow..

What do you guys think bout my swap? not many go h22 to h23!!

 

seems like alot of work

u need h23 exhuast mani.. not h22
damn man i just sold my obd 2 h23 engine harness too

damm i ll need the exhaust manifold even with the h22 block huh? i didnt even think of that, grr..

am i really going to have to change the engine harness on this?

**** i was hoping for just a swap of heads and IM and call it a day lol

Yeah since the Exhaust manifold bolts on to the head, not the block..

dammit , you beat me to my edit:
i didnt think of that, i saw the top of the head like valve cover bolts and was like .. easy as pie..

ok that is figured.. next?

 

what problems were you getting with the h22?

to me i think this h23 head might lead to more problems down the road. but like you said not many have taken this route so i dont know.

 

well with the car being obd2 and automatic.. yeah i know.. i am trying to get rid of the car and only way i can get it out of here is if its fixed.

anyways, with it being auto and obd2, the car came as Lx which was non vtec, we tried to wire and do this and that, and we got a million CEL's

i got nasty idle and surge and it jumpes at times, so many problems, nothing that we tried seemed to fix anything, we tried everything in the book but apparently the answer.. ecu problems.. and all sort of crap..

so i figured if i went with h23, it would remain non vtec and just would be a bit easier, since they make an obd2 auto ecu and all

 

i am pretty sure u will need a distributor from the h23, engine harness, if u kno someone good with wiring, u can keep ur engine harness

 

Why not just swap out the entire motor with your friend??

If you slap on the H23 head onto your H22 block....won't you have to change the water pump and crank pulley to H23's???

I believe that your distributor shoudl be fine. I thought that the H22 and H23 distributors are the same.

Also, if you need a brand new DC H23 header...let me know. I have one for sale.

we are no where near each other, i was going to ship my head and stuff and he was going to do the same..

if anyone in FL wants a h22 and has the time to do the work, i ll let it go real cheap.

The car is pretty much gone, just have to either fix the problems or put a new motor in so i can get rid of the car, its not a project or keeper!

You put the oil control orifice in to reduce the amount of oil going to the head. Over oiling it is a waste.

OBD means nothing for the intake manifold, although you may find you will be short a map sensor as the h22a one would be on te TB but te H23 probably won't.

You are running a 96 H23 ecu...that means you need an OBDII H22/H23 distributor to use to plug in.

Keep your H22a OBDII distributor, and let the other guy keep his OBDI H23 Distributor to use on your H22a head.

 

Thanks Joel.

i have the map sensor here from the current setup,

Joel you think or know if i will need to replace the engine harness?

 

why would you do that? A 96 H22 and H23 harness is the same minus the VTEC plugs...

I think the other guy was saying you need the harness to run the OBDI dist.

But ince you are keeping the OBDII H22 dist you will be fine

Great thats what i thought,

so: I would: you said the obd has nothing to do with intake manifold, dont the two different manifold use different sensor between obd1 and 2?

1 - i can take his h23 intake manifold
2 - reduce the oil ports
3 - replace the exhaust manifold and downpipe section
4 - swap out ecu's
5 - bolt up h23 head.

this should be all that is needed?

I just dont want to start this and then end up in crapville and be SOL.
