hey, i'm swapping a b20 into my 1990 hatch. i'm using a b18a intake manifold. does anyone have a diagram for all these freaking coolant lines.

 

simple. plug up all the small ones on the block, you can leave the intake ones open. my b16 is like this it also keeps all the warm coolant from heating the intake

 

Hi, i swap a B20 in my 91 civic hatch si. .. and would like to covert into OBD1 does anyone know what kind of wire harness will fit?

 

on all swaps use the harness that comes with the car.......just change the injector plugs and dizzy plug .......look for the write ups.....both dizzys use the same wire colors....just remember that theres two white wires one is by its self .....then but a jumper harness for the computer.......ive got a b20 in one of my crxs thats running obd0 ....with a pr4 computer...and runs fine

 

on ur b20 ....run a 94-up intake(flows better than 93-older) acura integra....

 

yes.. i run a 95 integra intake.flow... now i am running a obd0 integra distributor...and integra obd0 ecu.. ... the run okay but when it hot sometime the car have hard time to start... .. do u think is better covert everything to obd1? please help
