I don't think there is a way just by looking at it. Do you know who did the swap? You could try to get the vin off the block and call a dealer and ask what the year is, that might work.

 

Well if it's a swap I would assume they put the higher horsepower engine in. The 1990 RS comes stock with a B18A1 doesn't it?

 

Yeah thats correct,90 and 91 have the 130 hp B18A1 and the 92 and 93 (with the exception of the GS-R) have the 140 Hp engine.Where does that extra 10 hp come from...ECU map,intake,higher comp?

 

and more aggressive cams

 

If the head is original to the block, you can read the date on it.

 

i dont think that the engines make a difference cause they are both B18A1 90-93 the 10 hp comes from the ecu going ODB0 to ODB1
here is the specs for integra motor

and they have the same specs so u will have 2 see if there is a conversion harness to see if it is the 130hp of the 140hp
