I am doing the same thing except i'm putting a d16z6 engine in a 96 civic
Will the process below be the same for me. The example below the guy was putting in a obd1 b series vtec I'm putting in an obd1 d series vtec?

I have a 98 civic dx and I was wondering what I would need to do as far as wiring, to put and obd1 motor into it. I have tired to search but I can't really find anything. thanks

funny, about 3 people emailed me this same exact question at the beginning of this week and here's the info I relayed back to them:

"If you want to use an OBD1 B16A engine in an OBD2 equipped vehicle (such as yours), then you'll have to:

1) Reuse your existing OBD2 engine harness and add the respective VTEC wiring and Knock sensor if you own a non-vtec 96-00 civic...OR... find a 96-98 EX engine harness which already has the vtec wiring & knock sensor embedded into it.

2) Find a set of B-series OBD2 injectors...OR... or cut & splice the OBD1 injector plugs and adapt them to your OBD2 engine harness.

3) Find a 96-00/OBD2 B-series alternator ...OR... sell/trade the OBD1 B-series alternator for a 96-00/OBD2 B-series alternator. The plug is a square type on the 96-00 alternators and has 1-2 more wires leading to it, whereas the OBD1 alternator plug is a bigger round plug and has less wiring going to it. So there might be an issue if you try to rewire it...your best off fnding an OBD2 B-series alternator though.

4) Find a 96-98/OBD2 B-series distributor which will plug n' play w/your DX engine harness....OR...they say you can convert your OBD2 distributor plug to OBD1 spec by repin it to a dual OBD1 plugs and will accept & utilize an OBD1 distributor. I've never done this myself and I find a big pain in the *** (I personally hate rewiring stuff)....I suggest you find a 96-98 B-series distributor to make life easy on yourself.

5) ECU.
If youd like to go OBD1 ecu, purchase a 96-98/OBD2-->OBD1 ecu jumper and simply use an OBD1 ecu. JDM OBD2 ecu's programming is similiar to OBD1 programming as far as looking at sensors. It looks at the same exact sensors an OBD1 ecu does.......but for the US version of OBD2 ecu's programming, they look for a few more sensors which makes OBD2 a hassle.
US OBD2 ecu's look for these additional sensors:

 

bump for a yes no or maybe
