I'm being told that a b20 swap might not pass smog in California if I put it in my 97 integra, is that true? Can anyone answer that.

TheRealTegger

Since the B20 is considered a light-truck engine and the Integra is considered a passenger car, the answer would appear to be no.

You can read the details on BAR's website for yourself:
https://www.bar.ca.gov/Industry/Engi...uidelines.html

Particularly, see the first three Sections of that page.

No longer true. Call the BAR to confirm the details, but the B20 is now an approved swap. You'll need to carry over all of the Integra emissions and manifolding, so you'll be swapping in just the long block.

Never was a problem as long as it isn't being inspected. I've had mine running years back and never failed a smog test.

I called them today. I'm waiting for a call back.

I just got off the phone with the "California bureau of automotive repair " spoke with the referee he said I can swap in the B20 as long as I use all the b18 emissions parts, manifolds,sensors, etc. So just the block. And before smog check the OBD II needs to be set to ready. So now I need to figure that out.

That's easier than you think. The B20 is externally identical to the B18, so the swap is exactly the same as putting in a new B18 long block.

As for the drive cycle, just drive it a round normally for a few days before getting tested. The smog shops won't charge you and will just tell you to come back of all of your readiness monitors are not set.

I'm super excited that just saved me a lot of money.

TheRealTegger

That's right. Drive it around normally for several days, if possible. You need a few full-cold to full-hot cycles and a variety of driving conditions for all the monitors to run their tests and report "Ready".

IMPORTANT: Make sure the gas tank is between 3/4 and 1/4 full. The EVAP monitor tests will not run (and thus cannot report "Ready") unless the gas level is in that range.

And you get the bonus of a bigger engine!

I put a B20B in my 95 Special Edition. Straight swap, no after market parts, stock cat/exhaust. Passed smog without issues. If you have a guy that knows what to look for like the B20B stamp on the short block they might fail inspection but as far as the readings go it will pass no problem.

Good to see it can be bard now.
Will have to get mine bard.

Hi I need some help with my swap so as far as swapping over all emissions what does that consist of? My car is a 94 integra with a ls motor so obd1. I swapped over dizzy, intake manifold. Question is my manifold doesn't have the vacuum pipe to accept the center hose that cones from the valve cover? Is there a certain year manifold to use?

KPDSM

Does anyone know for sure...if I swap a b20 in do I HAVE to convert to obd2?

In other words, can I use all the OBD1 Integra emissions equipment and an obd1 computer with any b20 and pass?

If your car is an OBD1 car, then of course you need the OBD1 Integra emissions stuff. It isn't a requirement to have and OBD2 car to pass emissions.

KPDSM

Awesome! Thanks for response, looking for obd1 teg.

That makes my life so much easier/happier/better. B20 is the right price per potential to me. As long as I can use all the obd1 emissions parts to pass I think my swap will be pretty straightforward.

Yea the reason this thread was talking about OBD2 stuff was because his car was an OBD2 car. Basically, you're just swapping you Integra intake manifold/throttle body/air intakearm and everything that's plugged into them such as all of the vacuum lines, hoses, sensors and all of that. You put all of that onto the rest of the B20 engine and there you go. And of course if you're trying to pass emissions and such, make sure your O2 sensor is working right, catalytic converter's good, and charcoal canister as well. Pay attention to how the vacuum lines are hooked up and redo them exactly as they were once you put it all back together on the B20 engine.

I've seen and heard this working for some, but never in person, only online. Whenever we had this issue in NJ we kept a stock ls computer, ebay ueader, stock injectors off to the side ... Swapped everything out every two years and back .Took two of us but we got it done in 2 days more than once on a few cars...Gl

It is possible but you have to have your ecu in ready mode before they could scan. Which means driving around
