Help passing legal swap and smog
Hello, I am currently driving a 1999 honda civic dx hatchback and I am planning to keep this car for a long time. I have a rebuilt motor with a b16 head with B18c1, ITR pistons, and chipped p28 ecu obd2b to obd1 jumper harness. I was wondering what do I need to pass? And I am in California.

Re: Help passing legal swap and smog
If you want to do it legally, you need to swap a P72 head and manifold onto it, Get it running on a 00-01 P72 ecu, and get all of the Integra evap stuff moved over along with the stock exhaust manifold and cat. Is the car already registered and smogged?

Re: Help passing legal swap and smog
I had it smogged and registered last year, but with the d16y7 motor. I'm just prepping everything right now, I should've researched before putting everything together. If you need me to take pictures of my engine bay I could, I don't really know much about swaps and parts.

That's fine, it means you have a year to get your stuff together. Post a few pics of the bay and we can probably start pointing out things you need to work on.

Re: Help passing legal swap and smog
In the future please attach your pics directly to your posts... It's super easy to do. It's also annoying to have to click to another location, but I feel like helping so here goes. This is all constructive hopefully.
You have some work ahead of you.
- You have no iat sensor. The thing must run like garbage, that's one of the three most important sensor for the engine to run.
- I think I see the PHO2 sensor connector, so you don't have an oxygen sensor either. I'm going to take a wild guess that it doesn't have a rear sensor or a legal cat then.
- You have no PCV system. The valve cover inlet (where you have a tiny filter) needs to be plumbed to the intake tube (which needs to swapped to stock or to a CARB exempt intake). The intake manifold nipple needs to be plumbed down to the PCV valve on the back of the block.
- I can't see any evap connections. You need to have the correct functioning valve for the engine you have installed.
- You have a JDM ITR header on there. Needs to be swapped for a USDM stock manifold. You may be able to get away with it if the ref is cool and/or you have all of the heat shields installed so it's a bit more low key. You'll need the correct cat for the engine on there too.
- Your intake manifold is marked as a 98. Your engine needs to be a 99 or newer to be legal. Hybrid engines (mixing heads and blocks) is not allowed.
- Not emissions related, but you have two broken valve cover studs.
Easiest route would be to pull this engine and sell it, and get yourself a late model B16A. It was "optional" for this car so you can get it in there with all off-the-shelf parts, and all of the emissions stuff would be stock Civic and the ecu is a no-brainer. 2nd option would be a GS-R engine 99-01, 3rd would be a USDM ITR engine. those would be the more expensive options.

Re: Help passing legal swap and smog
Here are some more pictures, I was planning to switch the head to a p72 head, switch out the intake manifold to a 99-01 Integra, switch the header to OEM, get a Magnaflow universal cat with o2 sensor on it CARB Compliant, and OEM or AEM CARB Compliant intake system. I don't mind spending the extra money to get this motor legal.

Re: Help passing legal swap and smog
Forgot on my list yesterday... your VTP switch is not plugged in either. Instant code when you plug in the factory ecu
- Black connector loose near firewall is evap purge.
- Two 4-pin connectors in your hand are HO2S. You'll have to use a meter to figure out which is which. You'll need an extension harness or something to get back to the rear of the catalyst.
- IAT isn't doing any good dangling there. Needs to be in the intake tube, but will need to be on the manifold for a P72 head.
- Is your knock sensor installed/connected?
- Is CKF installed/connected on oil pump?

Re: Help passing legal swap and smog
It goes to your purge valve which doesn't appear to be present. The black plug mentioned above is for the purge. The purge is on the intake manifold for b16a2 and usdm gsr. I think that you have a jdm type r intake manifold that doesn't have the purge line . Hard to see in the pics.

Re: Help passing legal swap and smog
Op has a JDM header. Also I will add that we have a older thread on itrca about the magnaflow bolton cat not even fitting the Usdm integra type R . It's clocked the same as a civic . I returned that ish and got lucky. My friend had a oem one for me.I would really be irritated if I was in California and needed the correct carb cat that costs more than the 48 and then needed to be modified to fit. What brand are you using and have you tried one for a integra type r with success?

They sell adapters that go between the b-pipe and the cat converter but I would get the usdm cat 1st and see what the extra length you need will be.

Re: Help passing legal swap and smog
Let me help you.. I was on the phone with a ref the other day. The rules changed in late 2018, stricter now.
No more JDM engines allowed.
You must provide the VIN for the car that the engine came out of so that they can guarantee OBD type. No VIN? Plan on buying anothee engine with VIN.
The CatTmust be within x inches from oe location.
The O2 sensor must be within 1" of original location, AND MUST BE oriented in the correct direction.
No OBD adapters.
No splicing wires, must use donor wiring harness.
The list goes on.
Before proceeding you should read the rules, google it I think its called Appendix E or something.
Headache but if you read up first should be ok.
