Im trying to determine which version of the B16A I have. I know its not an A2 or an A3, but trying to confirm whether or not its a OBD1 or OBD0.

Jdm b16..anytime u see just the letter with no number after it, its jdm..like b16a2 is usdm..b18b is jdm LS and b18b1 is usdm LS

OBD1. Radiator fan switch is on the thermostat housing not back of block. 92 head casting means 92-94 motor. I'd say it has been pieced together though, the valve cover looks to be from a GSR

The engine is a jdm 1992 (2nd gen) 170hp model

94EG8

OBD1, the intake manifold, date stamp on the head and vtec solenoid are the biggest clues (and the fan switch)

It's a SIR II I believe I know it's the same one I got JDM B16A

And is the intake OBD1 or OBD0? The only reason I ask is because the motor came with an throttle body that was considered OBD0 and I guess my question next will be, what throttle bodies will fit perfectly onto this motor?

Deetz

It's a 2nd gen intake manifold for sure, only p30's were. OBD0 were stamped pr3. Any 92-00 b series throttle should work just fine on that manifold (94+ gsr will need a reverse throttle rotor)

i have a 1999 honda civic si with a B16A (stock) the vins on motor match the vins on car . Which is jdm. so its not just a 1992. its obd1 and they are pretty snappy. if there isnt a number at the end of the stamp on block then its jdm. these motors are highly popular and very common swaps.

Deetz

^^ The poster took a picture of the cylinder head stampings......they show his engine was made in 1992. That's how we know when it was made and that it was originally an obdI designation

Pics?

A 99 SI is NOT JDM it's usdm. A real SIR is one of two either a SIR I witch is a OBD0 or a SIR II witch is a OBD1 . Your engine is a B16A2 out of a 99-2000 civic SI Coupe That makes your car a OBD2 if I'm right that's why the vins match lol

dunkingmofo

His engine is not usdm its jdm and just because its jdm doesnt mean its SIR.
b16a2 is usdm that was stock engine for 99-00 civic si. b16a is from japan but fits usdm emission standards. SIR is straight from japan with no corrections, those are kind of hard to come by. Your engine is jdm b16a and im pretty sure its OBD1

If the VIN on the block matches the VIN on the body, either A) it's actually a B16A2, B) the VIN stamp(s) have been modified, or C) there's something else guy forgot to tell us about his car.

egsleepercivic

why was it set up for a firewall mounted map , my obd1 b16 had this as well

the pressure switch on the vtec solenoid shows obd1

I dont know the history of the engine and its mountings sad to say. Previous owner didnt have much to say on it in that regard. Currently Im looking to get a trans and a starter so I can test its compression, before I move any further into the project.

Sik Eg

I'm not saying his engine is a SIR I'm just saying what his engine is lmao. His is a B16A2 not JDM spec model . That's all I'm saying he thaught his is JDM but everyone know that the 99-2000 civic SI comes with USDM spec B16A2 not the JDM spec B16A2 that's a SIR just trying to tell him what he has . Anyway back to the ORIGINAL thread lol

Sik Eg

Bump for B16's

I appreciate all the info provided here. THough not sure what the GSR reverse throttle linkage is. Im not looking for extreme performance, so would a 94/95 accord throttle body work as well?

94EG8

Wtf are you rambling on about?

JDM B16As do not comply with US emissions (not without some parts swapping anyway) The JDM B16A came in the SiR, and no they really aren't that hard to come by

dunkingmofo

Thats what im saying..JDM b16a's dont comply with US emissions which in turn when they come from japan they are basically changed back to a b16a2..SIR is just straight from japan without changing the standards..

Deetz

What???? Sorry, what do you think is being changed on the engine?

Arthas

No purge valve. Def OBD1.

Arthas

PS, put the FPR vacuum line back to its original location.

angrysmileyface

Ok, have moved the FPR as suggested. Will a TB from a 95 accord V6 work on this intake?
