Trynna get my b20 bard, I was wondering if I can use a stock Ed/ef catalytic converter instead of having to find and buy a DA integra one. Was told the cats are the same

Do Not listen to anyone. Make an appt with a REF and ask them all the questions. I am currently attempting to BAR a 1994 GSR in my 91 Si and I need to use the Catalytic converter for the same year 1994 engine you are attempting to swap in.

Yes you can. It's considered a replacement motor for a b18a/b.

Caoboy

This is correct. The CC needs to match the motor. OP you can try getting away with the stock one but you may be wasting your time at the ref if they fail it for not matching the motor.

B00STD

Let me save you some time, a I already made the Ref appointment. The only thing I didnt ask them was about B20s, but I e never seen a BARd B20 and heard you cant.

Here are my notes from my Ref meeting from February, please schedule one yourself so we can compare notes:

CARB Bar’d - Notes


New Appendix E from Q4 2018 - New Rules Standards

Must use OBD1 same year or newer.

Burden of proof on you to prove where car came from.

You need to provide donor VIN from car (not receipt) to match up the engine to ensure its an OBD1 motor.

You need to use GSR wiring harness (for example), you can’t use spliced harness.

Need to place emission sticker underhood of your car from donor car. *Not a huge deal but preferred.

No longer taking JDM engines

Install a new catalytic converter:

1. Can only use passenger car cats labeled with “PC1” on their PDFs below. The OBD1 list is safer to use, the OBD2 list also works but they have dual stage cats (2 cats inline) which aren’t approved):

1. You can use any size cat that meets this requirement so 3” is fine but it must come from passenger car and meet the requirements of PC1.
   Note here: I tried searching for a legal 3" cat and came up empty handed, if anybody knows of 1 that would be awesome to find out.
2. Searching for legal performance parts:

Wow this is great information ! Thank you so much

Scotty23ef9

And by GSR Harness, do you mean engine harness or chassis harness?

Not sure the ref is 100% on that harness. I know several people that passed with an ECU jumper harness and a modified stock engine harness

B00STD

The guy I spoke to was pretty hard core. I would imagine this is your worst case scenario but if you want to do it once and be done this is your road map. He said that they are getting much tougher as of end of 2018. He said essentially you need to take the entire engine bay from the donor car and dump it into the new car. Depending upon the ref you may get away with spliced engine bay harness, but they can fail you for that. O2 sensir orientation and distance is also evaluated.

You should really stop spreading false information especially when you don't have a clue what you're talking about. Yes YOU CAN BAR a b20 into any 2001 and older Honda since as far back as 2013. Period.

Timothy just suck it up and buy a new cat for the engine.
