S14 SR20DET Help! To go Kouki or Zenki? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Yesterday i picked up my new motor, a s14 Kouki blacktop minus the ecu and harness. I have a source for the ecu and harness, but i need some input before i get them.

1) Ive heard that as long as you have a matching harness/ecu combo (zenki or kouki) that you can mate it to any s14 sr20det, is this true?

2) If so, then which route should i take? My motor is a Kouki, but should i pick up the Kouki harness/ecu or the Zenki harness/ecu?

Any input would be greatly appreciated.

Thanks!

a couple of the pins on the ecu are different. That only thing that is pretty crucial on harness's is the maf plug for the zenki and kouki is different. Motor wise they are indentical except for the cooling fins on the head found in the kouki models.

#1 you are correct
#2 i'd try to find a kouki set, but whichever is easier to find. I would take that route.

u need kouki harness and mafs and ecu

so the kouki motor MUST have the kouki harness/ecu/mafs?

Can i use a Zenki mafs if i splice the plug on the kouki harness?

is this why i might have a maf problem? i have a zenki s14sr20det in a kouki....if i let me my car idle for more then like 3 minutes it will choke once i give it gas at 1500 rpms....

motor was fine when it was in my zenki....

also my reverse lights dont work either.
