engine year?

im looking into gettting a apexi power and i need to know how i can tell what year my engine is ? im sure when i got it from autodream i was told it was a zenki s14 black top which means 95-96 but on the apexi site there are 2 different apexi units 1 for zenki and 1 for kouki …i called the apexi distro place and he said he was sure i would need the kouki but i dont want to mess up a big item like this

i have a 95 240sx with a sr20 black top ( s14)

apexi power who??? What are you talking about?

I’m guessing Power FC (ecu)? I could be wrong, I only know about the Power FC’s for the skylines.

A two second search on any american site will give you your answear.
