Ok so I am going by this method


I bought a jdm b16 2nd gen with hydro lsd tranny, obd1, so its not a 1st gen right? But looking at the numbers like in the picture above it says 9|1 but a 91 is a 1st correct. I'm confused Is it different on jdm or something

 

Motors that are casted as 6 month or later are put into the next production year. So if the head had 91 then a 6-11, it would be from a 92 model car.

Correct, you can also tell by the: connector colors and the block series.

Yes

 

also keep in mind that the SiR ll came around in 91 so even an engine that says 8|9 still has a likelyhood of being a second gen.
