Quick Question on motor swapping
I have a 97 civic DX HBK. I want to swap it w/a B18B. I'm a little confused as to the whole re-wiring thing. I wanted to eliminate that. So, would getting a obd2-1 conversion harness do? This means I can get an OBD2 engine, and OBD1 ECU and not have it throw any codes? Or should I just get the conversion harness and both OBD1 ECU and Motor? Or, am I just making it seem harder than it really is if I wanted to go OBD2 (B18B) and OBD2 ECU, what are the technicalities?

Ok, I want to stay legal so that eliminates that. I've done tons of searches for this swap there's some useful info out there, but I'm still confused. I plan on using the DX harness, is it all PnP with OBD2 B18B and ECU? Does it matter what year engine and ecu I get? If I get lets say a 98 B18b and 96 p75 ECU, would it matter?

No the years don't matter as long as the motor is 96+ and the ecu is 96-98. You will need to use your stock DX harness because that gen of civic has a one peice harness that loops trough the engine bay, you will have to lengthen a few plugs and change a few plug ends to accomodate the integras sensors like IACV I think it is a three wire on the DX, but only a two wire on the LS, you just color match the wires. There are a lot of small things you have to do but this specific swap is very straight forward. You will need the engine and transmission of course, and any b-series shift linkage, also you will need the 99-00 civic Si rear transmission bracket along with the cast iron mount that mounts near the timing belt on the driverside directly to the block. Do a lot of searches and you will find a lot of answers, hope that helped.

Re: (zerovandez)
You can run an obd1 ecu, but you are still going to need an obd2 to pass emissions in most if not all states, because they will use a scan tool in your diagnostics port and won't get a return signal with an obd1 ecu, I would wire everything up obd2 make sure it passes on obd2 then throw on the jumper harness and tune with the chipped obd1 ecu.
