OBD2--->OBD1 Harness?
I'm putting a B18C1 OBD2 engine, tranny, etc, the whole works, into my EK. But, in order to compensate for mods more efficiently, I want to get an OBD2--->OBD1 conversion harness. First of all, if what I eventually want to do is I/H/E/ and Direct port nitrous system, is it worth is to get an OBD 1 ecu and harness? Will the difference be worth it? The engine I got has a P72 ECU now (from an OBD 2 94-97 GSR). What ECU and Harness do I need to do the conversion (it's plug and play, right?) and is it worth it?

yes going obd1 is worth it because it will save you time and money during the install of the engine and to have our setup tuned for maximum power you will need to use something like hondata/uberdata etc which im 99% sure require you to be using a chipped obd1 ecu.

Re: (scarlemthug)
If you dont have to worry about emissions and and safety inspection, then I think its worth it to convert to obd1.
You have to:
-Reuse your stock harness and put it on the gsr swap.
-add the necessary wires(vtec, knock sensor, IAB)
-purchase an obd2-obd1 jumper harness
-purchase an obd1 gsr ecu
