Here's the engine number location:

However, that's not really going to tell you much. The easiest way to know what you have is to look for the "rats nest" under the UIM. Look to see if it has the "black box" solenoids as pictured in this thread:

rats nest will not tell you 265 vs 280 PS Hp engine, as it is used in both. 280PS engine has updated parts designated N3G1, however it stillused a number of parts from '96 JDM engine N3F1 and all the way back to our N3A1's
