I have a 1999 honda civic but an obd1 gsr motor. I would like to pass emissions. Is there a way to convert the motor to obd2b through new wire harness, ecu, sensors??? I alredy have obd2 Distributor,alternator, i need fuel injectors but is there anything else i need. Please if anyone can help, this is my last option before starting over with my swap

 

yes you can convert to obd2 but I think you're gonna need a crankshaft position sensor and a few others.

Sucks to have emissions. It'd be much much easier to throw it in your car and run an obd1 ecu

 

I already had the motor in the car running the obd1 ecu with the obd2 parts on the motor but it wouldn't pass inspection in NC. The car is not running right now anyway so I'm just gonna go ahead with the conversion, but i don't know of all the different sensors.

 

I believe your sensors are going to have to match up with your ecu. i.e. obd1 ecu will need obd1 sensors on the engine

 

I think the primary differences in sensors are the second O2 sensor and the Crank Position sensor. I've heard of people trying to swap the oil pump for an OBD II piece (the sensor physically mounts it) and installing the geared wheel on the crank pulley. I have not however heard of it working successfully. I'm sure it has but nobody I know has made it work and ended up with an OBD I ECU or check engine lights.

 

I am going to use obd2 ecu.

 

if u have a obd 1 ill take the harness off ur hands let me know asap bigvcreations@aol.com

 

I don't think you are talking about the Crank Position Sensor, you are talking about the Crank Fluctuation Sensor.

If you are savvy, you could navigate the DMV regulations and see what it would cost to get the OBD2 put on the rollers (assuming you would pass that way.) Also some states have a waiver for emissions altogether if you spend XX amount of money on the car and don't get it to pass emissions.

You might be able to buy a shiny new exhaust and have that count towards the money,
