Obd0 or obd2? and harness questions
So I just bought my first ever Ef/ed hatchback std model and I got a 2000 b20z I’m trying to put into the hatchback. I’m going to convert it to obd0 to get it bard but what intake manifold,cat,and etc do I use? Do I use the obd2 B18b stuff since the motor is obd2 or do I use the obd0 b18b stuff since I’m going to go obd0? Or does it even matter what year stuff I use? And the last question, are the std and dx harness the same? If not could I still do the mpfi conversion on the std harness. Thanks.

Re: Obd0 or obd2? and harness questions
you are not going to convert it to OBD0 to get it barred.
The BAR ref is going to look at the codes on the engine and see that it is a B20.
Then they are going to do their job and look it up and find that it was not offered with OBD0 electronics.
He may even be a bit more cautious because the engine is from an SUV and not a small passenger vehicle.
He will then send you home.
For BAR, need all the emission system and electronics to match the year of the engine.
Changing the manifold? Wow... you really don't want to pass BAR inspection.

OP
what you need to do to keep it obd0 is ref it as a replacement engine for a b18a1
basically put the obd0 intake manifold, exhaust manifold and cat converter for the year Integra you want to bar it as.
Get the correct ecu for the engine. Aka pr4.
Swap it all in, make sure there are no cel codes and your timing is set.
Pass ref and enjoy.

Re: Obd0 or obd2? and harness questions
Yes they do since like 2013. Reason being is because it is harder to acquire b18a/b supposedly, and due to the similarity of the motor, it is alike enough that they finally allowed it.
