View Full Version : Can someone help me identify this Motorset combo? S14 sr

so with all my trouble with this motorset i got to realize that it doesnt seem as if my ecu and motor really match. i read up that the WC ecu is zenki along with the 69F00 is also a zenki code. and the cooling fins on the head are Kouki.... well i have both. any ideas if i have the wrong combination of the two? could that cause my car to run like shit.

and the kouki wiring harness shouldnt plug into the zenki ecu either should it?

heres a pic of the head and the ecu.

Google is a awesome search feature ( search { WC nissan ecu } )

WC is from a 94-98 S14 Silvia

you might need an s15 ecu, the head has fins so it might be a late model kouki sr or an s15 sr.

thanks for the input. i did search and found out that my ecu is from a 93-95 s14 silvia. so im assuming its the wrong ecu for the motor? i also pulled the vin from the motor, can anyone help me determine the year of my motor then? it was

SR20 263365W

^^ it was like diaganol from my exhaust manifold.

what makes you think i have an s15 sr? its five speed but obviously the tranny could have been swapped out...
