difference between OBD0 and 0BD1
I just bought a B16 swap for my 90 civic.... everyone keeps asking is it a OBD0 OR OBD1... Hmotorsonline says its an OBD0 but what is the difference between the two?

Re: difference between OBD0 and 0BD1
OBD0 (or more correctly non-OBD) is 91 and before. OBD1 is 92-95. If you got an ECU with the swap, the ECU can easily be identified as OBD0 or OBD1. They have to be visually inspected though, the same ECU numbers (usually either PW0 or PR3 for B16s) were used for both OBD0 and OBD1, even though the ECUs looks completely different.
There are ways to identify the engine also, but it's not as straightforward.
