so here's the deal, my extra B17A1 and my 92 GSR are both in different states than where i live so i can not confirm anything for myself... i know the GSR's came with the P61 computer, atleast i could have swore so? and the P61 is OBD1, but on my GSR i know for sure there is what i thought was an injector box on the passenger side fenderwell. which if it is an injector box that makes it an OBD0... i thought it was an OBD0 car up until a few weeks ago where i was readin otherwise... i never had any need to repace anything that would have told me which OBD it was... never had any dist. or ignitor problems, only threw a hard code once and when i did i just pulled the motor out and put in my other B17A with out checking it HAHA but i'm sure it was from fueling cause that was when i snapped 2 studs off theturbo manifold and the turbo damn near fell off... (when we were griding the block to make the turbo fit i didn't grind enough and the turbo never really did fit right...)

 

all integras thru 1991 = obd0 92-95 = obd1 96+ = obd2

well as i do not disagree with that, i ask then this, fellow DA/DB2 owners, what is that box on the passenger fenderwell? it has a plastic lid by the way...

 

OBD series computers follow the civic model years IIRC.

89-91 OBD0
92-95 OBD1
96-00 OBD2

i'm not sure anymore where the switch from OBD2a to OBD2b is though.....

My 00 is OBD2b where my buddy's 98 is OBD2a
both GSR's if that helps any.

I think it went to B in 00 but not for sure.

 

OBD2a is 96-99
OBDb is 00+ (not sure of end date on that)

 

i have had two DB2 and i'm not sure what box you're refering to. but they are obd1.
