Just got a 2000 GSR motor into my 2000 Civic. I'm using the stock harness on the civic. The car came with a 1999 b16a SIRII. The dizzy off the GSR I just swapped in had a different dizzy plug on the harness, so I ended up using the 99 b16a distributor instead and the GSR seems to run fine.

Does anyone know if the 99 b16 SIR2 dizzy and overall motor is obd2a or obd2b? Any way to tell the difference between an obd2a vs an obd2b dizzy? Need to know due to BAR related issues.

I know in general in USDM motors, 99-00 Civic is obd2b and integra is 00-01, but was not sure if this is also the same for JDM engines.

 

OBDIIB are all Honda's from 1998 or 99, can't recall the exact cross over. The B16 dizzy should work just fine.

 

I drove around and the car sputters. I got CEL 8, which is top dead center sensor, so something is up with the distributor. The dizzy worked fine on the 99 b16a SIR2, but it's throwing a code now. Any suggestions?

 

bump because i want to know the difference.
