Obd2 & 1 sensor question
I’m in the market for a manifold for my obd1 b20.
I was told to purchase a 94 - 95 obd1 LS intake.
Are all the sensors the same for obd2 & 1?
In ”theory”can I buy any LS intake manifold and it will plug right up to my 93 civic harness? Or does the manifold have to be obd1 specific?
I think I read somewhere while doing research that the sensors are the same but I just want to make sure so I don’t bend myself over lmao

Re: Obd2 & 1 sensor question
A '94-95 LS intake manifold will work the easiest... primarily because the IAT sensor is mounted in the #2 runner and the purge/cut solenoid is NOT mounted on the intake manifold. If you are using the fuel rail and injectors from the same intake manifold, then you should definitely use the OBD-1 manifold. You can use the newer OBD-2 manifold castings, but you will need OBD-1 injectors or modify the injector clips and purge/cut solenoid clip.
