Obd1, Obd2
Is the difference between OBD1 and 2 only in the ECU?
By what I've heard I'm assuming that you could have a 96 civic, get a b16 motor and have an OBD2 ecu. That ecu would wire up to the place where the DEQ plugs into your computer....?
Now if you have a 94 car, could you get an OBD2 ecu and actually hook up that shiznit? I know the DEQ wouldn't plug since the car is a 94, and I've heard that OBD2 is not the desired type because of all the sensors and bull****.
Fill me in here...

OBD = On Board Diagnostics
Think of it as a "generation" of ECU. '92-'95 cars use OBD1, '96 or newer are OBD2.
If you have a '94 car you can get a '94 B16 ECU from a del Sol VTEC. If the car was not already wired for VTEC you'll have to add a couple of wires.

how difficult would it be to take a 96 or newer integra ls motor, which i know is obd2 and put it in a 92 si hatch. The newer motor has lesser miles, slightly better effeciency, and slightly superior power, that is why i want to know

Yes, OBD2 has another oxygen sensor. That's not where the name comes from though.
An OBD2 B18B (LS motor) will bolt in without much fuss to the hatch. You can either rewire the car to OBD2, or get a '94-'95 Integra ECU and plug it right in. Check out http://tech.hybridgarage.com/ for more detailed info on what is involved in doing the swap.
