90-93 are all stamped B18A, 94+ is B18B. Look on the head above the exhaust port for cyl. #4 and you’ll see a little circle with 2 numbers in it. Those two numbers will tell you the year of the engine. It’ll look something like 9|2 for a '92 and so forth.
90-93 are all stamped b18a? thats just dumb. =) I didn’t know.
90=100xxx
91=200xxx
92=300xxx gsr=100xxx
93=400xxx gsr=200xxx
this is the # under b18a1
Leftcorners way is easier tho., but it works also
