how can i tell if a distributor is an obd2a or an obd2b distributor? http://www.hondaautomotiveparts has them listed as different stock numbers. any pointers?

Robzible

it all depends , i know all of the 96+ integras are the same , but as far as sohc's go , the obd2a and obd2b , the difference is the plug

Civiclx

so how can i tell the difference, how tdoes the plug of an a look different than a b

I believe its all the same. I know for sure the only thing different is the plugs for the ECU between OBD-2 A and B. I never heard of something like that before. I dont know why they have different part numbers but they both should be the same. Sorry I cant be much help.

Civiclx

its ok, thanks can anyone confirm this? going once...

Robzible

umm basically the 96-98 obd2a civics use one large plug , the obd2b civic uses a smaller but still yet only one plug distributor , that plug is actually the same plug as the 92-95 obd 1 plug , the big side , but however all 96+ b series in del sols , si's , and integras use the one large plug whether it is obd2a or obd2b , sorry if i confused you , let me know if this doesnt make sense and i will try and explain it better

so can i use a 99 obd2b plug on my 97obd2a?

Robzible

i have a d16y7 block (1997) with a d16y8 head (1999) i am having timing/ rich issues and i was wondering if maybe i used the wrong distributor... should i use my dx obd2a distributor or the ex obd2b distributor, i know they are the same between the ex and dx but im not sure between the obd2a and obd2b years

Robzible

hmm now that i dont know , what ecu and injectors are you running , also what intake manifold; just curious

Civiclx
