Alright, well i JUST bought a 1992 Prelude Si, and as luck would have it the engine blew 2 days later. So now i have to put a new engine in it. I was originally gonna replace it with a standard H23a, but for the price my mechanic was quoting me, it was just as cheap to get a H22a. Here is the problem. The motor is JDM, and the guy i called at passwordjdm.com said that the wiring harness has about a 95% chance of being cut. Is that a problem because if im gonna get this engine i want to be able to use the vtec. I really dont know a heck of a lot about cars, but i know that the vtec system only needs 2 pin outs on the ECU (which is going to be p13). Will my old wiring harness from the h23 work, or will i have to spend another 680 on a new harness?

EDIT:
Oh, and will i need to get a new shifter cable, or will the one from my H23 trans work for an H22 Trans

EDIT2:
Okay so on page 8 of the search i found my answer.
I can use the H23 harness, but i have to run wires for the VTEC Pressure Switch, the VTEC Solenoid, the VTEC Ground, the ignition coil, and i have to change out the fuel rail from my H23. Since i had a problem with my EGR on my first engine i dont think i can transfer that one over.

I still need info on the shifter cable though, and if i have missed anything on the wiring for the new engine.

Nice job on the searching.

Your current shift linkage will work perfectly.

I did this when i had my prelude is real easy. H23 harness will work fine , just have the mechanic run the whires for VTEC. Everything else will work good to , but u might wanna invest in the h22 tranny , or later on down the road. I just preffer with that engines , the gears are longer and not as short as the short ass h23 gears.

reikoshea

Thanks for the info on the linkage. My mechanic told me something about ignition coil (i think) being internal and not external like on the H23. Does anyone know how to go about wiring that with the h23 harness?
And i do have the h22 tranny comming in. The old shift linkage from the H23 will still work in the h22 tranny right?

dohcvtec_accord

Yep.

Also, tab should be able to help you out with the wiring of the interal coil distributor. B)

reikoshea

HEEEEEEEEREEEE TAB...



If possible just link me to a thread that this has been answered in. The guy knows what hes doing and he just doesnt wanna screw it up (and i dont want him to either). He wants to make sure he has the wiring on the distributor and the ignition coil right. Also if i have not said something that needs to be done please let me know. I read something about a knock sensor (i dont think the h23 had one). So what needs to be changed for the motor to work. Its an H23 Harness, H22 Engine, H22 Trans. I have bought a new water pump and timing belt (grr cause i just replaced them before the old engine blew), is there anything else that needs to be purchase? As much detail, or links would be EXTREMELY helpful. Thanks for all your help.

lol...for 50 bucks more i can get the motor from hmotorsonline with the full harness...i make life too difficult. I still need to know what all i need to buy minus the waterpump and timing belt.

dohcvtec_accord

The H23 had a knock sensor.

At a minimum, you'll need to buy new plugs, wires, cap, rotor, oil and oil filter. Anything beyond that is up to you, since everything is easier with the engine out of the car.

reikoshea

by cap, you mean distributor cap right

and by rotors you mean for like the AC compressor and the alternator, not the brake rotors right?

dohcvtec_accord

Yep, distributor cap.

Haha, no, I meant the distributor rotor.

reikoshea

Well see, this is why im having HondaWorks replace my engine rather than doing it myself.

Is the new distributor stuff more prevenative maintenance, or is it required?

reikoshea

Well i found out why you suggested that i replace those items.

In order to qualify for the warranty on hmotors you have to replace them.

It looks like everything is gonna work out pretty well...i have to pay an extra 50 bucks but i save a hundred and twenty five on shipping, so im doing pretty well. If my service guy runs into any problems ill be sure to tell him to look here yall (dohcaccord_vtec) really rock.

tab

The distributor wiring is easy. You just find the hot wire and run it to the distributor.

They do go bad, so you can(I've heard) use the H23 distributor. Also, I have learned the hard way that you can convert from internal to external coil, but it takes a while.

My old H22 distributor went bad from sitting in my garage for 6 months. It was running when I pulled the motor. I had two F22 dizzy's laying around, and I found the housing shapes to be quite similar. Sure enough, the internals were the same bolt pattern, except the F22 was external coil. I dismantled the F22 and H22 distributors, and swapped all of the electronic pieces. I retained the H22 housing and shaft, since they were DIFFERENT from the F22 dizzy. It works fine, and has for about 4 months now.

This is like H22A dizzy wiring for dummies, no offense. Scroll down, I have it in a public forum.

Thanks a bunch tab, thats exactly what they needed.

One more stupid question from the peanut gallery though

I live in TX and *sniff* this was gonna be my first car with ac *sniff*, i can take the old ac compressor off my engine and put it on my new one...right

(And they are probably gonna have to do it with the power steering pump too, huh?)

tab

With the right combination of mounts, you should be able to keep all of your accessories.

reikoshea

so by that you mean the old mounts from the h23 wont fit on the h22...they look similar but i think the exhaust manifold might be too long.

tab

The exhaust manifold is not an accessory. By accessory, I mean something driven by a belt. You can use all of your stuff, but you'll need a different manifold.

reikoshea

lol i guess i should stop with all the elpisis crap (...s)

I meant that the exhaust manifold was too long so it would get in the way of the ac compressor. But i called the guy at hmotors and he said they had the same mount.

RICK_FD3S

Tab you are right. If you are using the H23 wiring harness you can use the H23 distributor. The other thing you are going to need out of the H23 is the radiator hose elbow at the front of the motor that has a plug in it. Just make sure you use the H22 injectors. As for engine mounts I'm pretty sure I use all the same as the H23 with not problems on headers fitments or anithing.

tab

There are a half dozen ways to do anything, or six ways to do it. If it works, use it. This isn't a braniac swap, so just think your way through the problems as they come. There aren't that many surprises.

USDM engines have an extra fan switch on the front of the motor. Use your stock stuff(switch it).

reikoshea

Yeah, why cant yall live in TX. This is just getting dumb. I still dont have my car back yet. I dont know what the deal is, and id rather not take the day off to fix the shit.

do i really need to mount the external coil if i were to use that. It can get rubberbanded or zip tied temporarily and still be fine, right?

And if i told the guys NOT to wire the vtec wires throught the strut wire cluster (i totally know what its called, but i had a brain fart) should it really take that long to mount the accessories, attach the harness, reattach vacuum lines and radiator, change fuel rail, and ummm normal tune up crap. (timing belt, oil filter etc)

I say no.

External coil distributor means you'd need the external coil, yes.

Do you have the internal coil dizzy? I'd like one back since my old one went bad. I swapped out the guts and converted to external coil. I zip tied mine to my air intake for now(sux).

The other shit shouldn't take that long for a competent shop or mechanic. I can wire VTEC in 1 1/2 hours. The other crap is easy.

reikoshea

ill make sure to grab the dizzy off my old motor. PM me with an address and ill send it to you for all the help you have been. (ill pay shipping)

reikoshea

Holy crap...what are the chances that the engine/electrical guy gets food poisoning on the day my car is supposed to be done. Friggin grr...the owner said exactly the right thing that would prevent me from getting a tow truck. "I dont know where he stopped, but i dont want anyone else working on it, because i dont know where he stopped." Really good answer, cause id rather not miss a vacuum line because i didnt know he hadnt gotten it...so i guess ill wait, but ill make sure to get you your dizzy, tab.
