I have a 88 civic lx and a OBD2 ls swap. Is it possible to convert that or can I or should I change it to an OBD1 set up. And is one better than the other.

Thanks

 

obd-1

 

OBD-1 is the #1

 

How do i change it to Obd1

You above statement tells me that you have an OBD0 car and you have an OBD2 swap right? But you can decide between OBD1 or 2?

I would go for the OBD-1 since it is less wiring, its cheaper, less sensors and Its just cleaner.

 

can the obd2 motor be changed to obd1 or should i sell it and get an obd1 set up

 

I am sure that there is a Jumper Harness to suit your application.

Check this out.
I am running a P28 (OBD1) ecu with a obd2 engine and a OBD0toOBD1 jumper.

 

Just look at a OBD1 motor, see what sensors you need and plug as necessary, thats what we did on my car, OBD2 motor but running OBD0 still, just had to get sensors off the old motor and plug one or two sensor holes on the block...or something like that, dont remember since it was like 5 years ago.

 

the few things about an obd2 engine that makes it obd2 is the dizzy, injectors, ckf sensor, and evap equipment. now the obd2 dizzy has the same internals as an obd1 unit, and the injectors, although they have slightly different clips, are both saturated and of the same flow rate. so if you so choose you could wire up obd1 plugs on the obd2 distributor. if it happens to be obd2b then you will also need to run a wire out of the dizzy for an rpm lead. obd2b vehicles don't get the rpm info from the dizzy so the terminal is still in the distributor, it just isn't used. also you can use whatever type injectors you want. obd0 and keep the resistor box, or obd1/2 and delete it. lastly for the obd1 and obd2 blocks you will need to extend the coolant fan switch wires from the back of the block over to the side of the cylinder head on the thermostat housing. so either get an obd0 pr4 and keep it obd0 (which means you will need a new distributor) or go the obd1 route and use an obd1 pr4 or p75.
