Sup everyone.
Okay my question is i am swapping my 93 integra JDM b18b1 OBD1 LS motor with a b20b. My thing is, will my OBD1, ecu and wiring harness work with the b20b. and of course i know i will have to ref. the car since I am doing a motor swap correct.
This is my first swap so i need as much info as possible since i cant find the JDM b18b1 (not b18ba1) ANYWHERE!!!
Please help.
You will not be able to ref with a B20.

call your local ref.
they’ll tell you to look in to a h22a swap which is still a compact vehicle engine.
a B20 is considered a truck / SUV engine.
a B20 is also a obd2 engine so you will have to convert you car to obd2 emissions like the evap, sensors and cat. so your lucky you don’t have.to do all that since a B20 isn’t legal. I say go big or go home so of your swapping a engine go B20v and screw the smog. I pay $150 every year to pass smog and it. easier since your still obd1 or obd0.
