hey guys i have a 96 hatch cx model. its my daily driver year round and i wanna do an H22 swap. I'm in N.Y. so it needs to pass emissions inspection. I'm not sure whether to wire it obd2 like it is now, or wire it obd1 and run my stock ecu for obd2 inspection, if thats even possible. So i need to know whether to get a 92-95 h22a(200hp) or an 00-01 accord euro R h22a(220hp). need to know what to do and how to go about wiring it so i dont have any issues. also curious about exhaust options. goin to order from Hmotorsonline and use hasport mounts. thanks josh

just curious but can't you take it for an emission inspection before you do the swap, then swap it after? get the accord euro R.

yea i can, but im not gonna do a motor swap every time i wanna get it inspected. gonna need more info than that

If you want it to pass emissions all the time with not much work go with the Euro obd2 since your chassis is obd2. I myself have a headache with an obd1 h22 out of a 94 in my 2000 civic si and im running the P2T obd2 si ecu now. After putting in the obd2 ecu I got about 7 Check engine codes and I've narrowed it down to 3 left so far. So you can go obd1, but to make it pass emissions is just a little more work and will need some obd2 parts for the motor. Good Luck with whichever you chose!

Don't bother doing the swap unless you do an h2b swap. it's not that more expensive, a lot less headache, and it's going to be a lot better in the long run.

Read through both of these.

Not sure how your emissions works, but here it's just a matter of your car putting out the right amount of carbon deemed legal. They don't open the hood as far as I know.

You can do an h2b as an Obd2 engine if you're willing to pay more for the harder to find block. or obd1 if you find your run of the mill h22.

Let's face it though, you don't want to do the swap correctly, just swap in a b16 and spend $3000 on shiny parts that make you feel better.

Dude what does H2B have anything to do with passing emissions? H2B is a kit for an H22 to mount up to a B-series trans, that has nothing to do with wiring or inspections. Just gear ratios.

He said he "wants to do an h22 swap" I was simply trying to save him the trouble of hacking up his floorboard. It has nothing to do with emissions, which is why I continued and gave my fill on the emissions part as well.

thanks. that does help a little. sounds like a difficult swap. wiring scares me. still saving some money for the swap, so i still have time to think.

Not sure how NY emissions work...whether they just plug into the OBD port and make sure everything is good or if they check under the hood and everything like in CA.

If it's just a plug and go type of deal, you don't nessecarily need an OBD2 engine. You just need to wire it up like OBD2. From what I understand about H22 swaps is that just like a B series swap, you use your stock civic harness. You just rewire a few plugs and run a few wires to make sure everything is plugged in. It's not difficult. With an H22, I do think that you have to do some re-wiring to make sure the engine starts and runs with the USDM external coil distrubutor...or use a JDM distributor. Not sure on all the specifics, but you get the idea: OBD1 engine, OBD2 wiring and ECU. Or OBD2 engine OBD2 wiring and ECU. Doesn't matter as long as the wiring is right. The engine is just a peice of metal. The ECU doesn't care when it was made.

I think people usually use OBD1 ECUs with a conversion harness to actually run the swap, however. Usually, it's some chipped P28 deal or a Hondata.

For emissions, you should be able to swap in your stock D series OBD2 ECU. You then wait a few days for the ECU to become "ready" for emissions checking and go in and have them scan you and let you go. You then swap back out to your OBD1 ECU and drive on that. That's how people do it in IL.

If they do inspect under the hood and require you to have a motor itself that's OBD2, then it's a different story.

Any swap you do is going to involve the same amount of wiring any other swap would require, for all intents and purposes.

Inspection stations just plug into the port to make sure there is no codes present, so that shouldnt be a big deal then. i just wanna make sure that everythng is cool thats all. i have been told that i run my stock ecu for the inspection, but wont that hurt the motor? especially if i have to drive it for a few days prior to inspection so it relearns itself.

No, you're not going to hurt the motor. Just don't bury the throttle a lot.

92hondaex4door

ok,that makes me feel better. I'm just getting back into the tuner scene and i just want things to be right, because we all hate headaches. i used to have a crx with a b16a alomost ten years ago and i had alot of fun with it ,no issues. hope to make some friends on here and learn a lot. I'm curious though , should i do it all obd2 or get an obd1 h22 and wire it obd2? thanks for the help.

Libertariat

You can't wire an Obd1 for obd2, you'd have to install/fabricate/etc sensors that an obd1 engine doesn't even have.

obd1 = less sensors
obd2 = more sensors.

You can make more do with less, but you can't make less make more.

If you want to stay obd2 get an obd2 engine and an obd2 ecu.

Huh? I wire up OBD1 b series engines as OBD2 compliant without any sensor additions all day every day.

There's only ONE additional sensor anyway. And I'm pretty sure you can fool H22 setups into ignoring it....especially with a civic/integra ECU. If ny emission tests are just plug in tests, you dont need the CKF.

I've only done 1 h22 swap. It was a JDM OBD1 swap into my friend's OBD2 prelude. I had a CEL, but after some crafty distributor useage and wiring changes, we were in business: No CEL or issues. Too bad I can't remember wtf we did. This was a while back.

92hondaex4door

well i really want to do the euro R h22 cuz its another 20 hp over the other. but its a lot lot more money. so i will prolly end up doing an obd1 h22 as long as i can wire it up correctly and it will pass emissions. thanks guys
