Hi there guys, I have an EM1 with a B16A SiR-II swap in it from a same-gen JDM Civic SiR. I need to order a new VTEC Solenoid gasket for my little leak and was wondering what OBD my B16A SiR-II is. Looking on Wikipedia, the specs say it's an OBD1, but on some this other thread here on Honda-Tech, the guy says that it's an OBD0 and that I should use the gaskets from a 90-91 NSX (Part #36172-PR3-005). Which is correct and which part do I buy?

 

u have an obd0 motor i have the same one that i pull out of my ef si to put in my eg 4 door. not sure about gasket though.good luck.

 

Thanks for the tip, but are you sure though? I'm still quite confused and I looked at this website over here http://www.jdmenginedepot.com/jdm_en...mission,_&_ECU and there are specifications indicating that it's an OBD1 motor. Everyone I've seen on the forums have been saying it's OBD0, but on specs from other websites, I've seen it as OBD1. I mean I can always buy two gaskets and just return one, just to see, so maybe that's what I'll end up doing.

 

Well, there are ways to tell if a motor is OBD0 vs. OBD1, aren't there? I mean, even the connectors are different, are they not? What ECU are you running? And ... what do you mean by "same-gen JDM Civic SiR"? If your EM1 is a 6th Gen Civic, wouldn't that mean OBD2a/b?

 

Yeah I know there are ways to tell them by the connector, but I don't exactly have the car with me right now and I won't be able to see it for a few days. And I'm not exactly sure what ECU I'm running at the moment, haven't checked that either. And yeah my EM1 is a 6th Gen Civic, which was supposed to come with the OBD2B on the B16A2, but that's been swapped out.

 

Nevermind, thanks a lot for the help guys. I just figured this out. Ended up asking the mechanic to check up on it and it is an OBD0. /closed

 

W O W!!!!!!!! HEY GOOD LUCKY.
