Well i put a b20 in the hatch today and everything went pretty smoothly...I just want to know what I should do about my O2 sensor placement and my lack of a cat! Will i need to have the 2nd O2 after a cat? Will i have a CEL still on even if both O2's are in the exhaust? This is my first OBD-2 swap, i was a HUGE EF/DA fan so...i am moving on up and learning as i go! Thanks in advance! Also is there any draw back to extending O2 sensor wiring? I will heat shrink and solder them if that makes a diffrence!
I am done!

you need to wire in the o2 sensor/plug to the harness.

 

i this lawrence? This is dutch man. I have the O2 sensors but i just need to get the O2 sensor bungs welded in before i head back home! I have no cat and i just want to know if i will keep throwing a CEL if i dont have a cat? I also got all your stuff no one in town had the valve cover grommet things on top...dont knwo what there called. It was like 55bucks and some change just hit me back with 50 since you got my in n' out that one night! I will hit you up when i get back to check out the swap! Also what throttle cable do i need?
