I want to do a b16a2 obd1 in my 94 civic hatch, but there isnt much out there on it. Is it the same wiring mods have to be done for the b16 as the b18? there both vtec.

 

I think the B18 is considerably different... but don't quote me on that.

 

B16A2's are OBD-II, bud. It wires in like any other OBD-II B16A.

 

he said b16a2 obd1, which I'm guessing he really meant a b16a second gen, but most online shops just label the second gen b16a as b16a2...

but to answer his question, the second gen b16a has the exact same wiring as the obd1 b18c except you do not have to do the butterfly valve wiring, and also the evap purge wiring isn't nessecery

 

thank you. that helps a lot.
