I have a 1997 Honda Civic DX. I want to put a B16A2 engine in it. The problem is, I've figured out that my car is OBD2, and if you put an OBD1 engine in it, it won't pass emissions tests. I need to pass this test with my car. My question is, if I get a 92-95 B16 engine with an OBD1 ECU, but then go out and buy an OBD2 ECU and switch them, will this be emissions legal? If this will work, does anyone have any good websites that sell ECUs at reasonable prices? I could really use some help on this one.
