s14 sr20det PROBLEM!!!!!!!!!

[mjr321]

ok so here it goes.today i was having a huge issue as to what maf to get for what i thought was my kouki s14 sr.so i went through hell figuring out that the the proper one was the one with the part number 22680-69F01 thats for kouki.and i thought i knew this because my ecu is labeled "NA". and through my research i saw a comment that s14 zenki sr20s are the ones with the fins on the front of the head.which i always thought indicated it was a kouki motor.so i was confused and thought hey lets try to plug the ecu in the harness to double check...and what do you fucking no.the plug is to big to attach to the ecu.so im thinking im fucked.i keep researching and find out that sometimes the motor sets are sold with the wrong harnesses attached.so people i need your help.did i even have a kouki or is it a zenki?? how can i find this out?? any codes on the motor to narrow it down?? is there another ecu made for the kouki that this plug can plug into?? or is it a zenki and now i have to find a new "WC" ecu and buy the maf labeled 22680-69F00?? what the hell have i gotten myself into here?? i need help with this one..and yesterday i bought a s14 kouki transmission.can i still use it??well zilvia these questions answered would be awesome.i really wanna get my car done.thanks

Did you not take english in high school? Why do you keep using ... instead of a freakin period. And learn how to write a proper sentence before posting. I can barely read your post before getting annoyed with it.

First, all sr20det transmissions interchange.

Second, it doesn't really matter if your engine is zenki or kouki when looking at the harness or maf. All the sensor plugs between the engines should be all pretty much the same. Basically right now if your NA ecu doesn't fit the plug, then you probably need a WC.

And I am pretty sure its the zenki that has no fins on the front and the kouki that does have fins.

ok so your sure its the zenki that doesnt have fins and the kouki that does? that makes no sense. and i fixed the periods. and yes it does have the fins. the motor is in my room. im looking at it right now.
and what do you mean it doesnt matter if it is zenki or kouki when looking at the maf and harness?
is it possible then that i have a kouki motor with the wrong harness?

[mjr321]

come on people just read it and help me out here. i really dont know how to figure out if its a kouki so i can get the correct harness. or if it is a zenki to replace both the harness and ecu and get the correct air flow meter

[garagelu]

you can interchange a kouki and zenki harness is what I mean. You just have to use the corresponding ecu. And maf is the same on all s14 sr.

And no I am not positive on the fins on the head but thats what I always thought. And I wouldn't go by that as a way to identify the engine. Another way to identify is what filter fits on the oil filter block. I know the earlier s14 sr use the same filter as the 91 sentra se-r and the later s14 sr uses the 95-up sentra se-r filter.

But keep you s14 sr engine and use the harness and maf that you have. Just find the right ecu that will plug into the ecu plug you have right now.

and fyi, I have a wc ecu for sale if you want it. PM me.

And just found out.....the only difference between kouki and zenki maf is the plug. One is a wire retainer and one is push clip. The kouki plug will go into the zenki maf and vice versa. You can interchange the maf and not model specific.

Can you not plug in your maf plug into your current maf?

[mjr321]

i do not even have the maf yet. i was doing the research as to which one to get, which is what made me stumble across this problem. i am almost positive it is a kouki sr with a zenki harness.
and how else can i identify the model of my motor without removing the oil filter in my room and having an oil war by my bed???

[mjr321]

bump.............

[garagelu]

Why are you so worried about whether you have a Zenki or kouki sr. They are the same freakin engine. I don't understand why you keep askin the same question. You have a Zenki harness so get a wc ecu and buy a s14 maf. Like I said, maf is same. Plug is different but you can interchange.

What else do you need to know?

[mjr321]

Is it that you dont really wanna help and have your way with my setup? Or you just dont know how else to identify the motor?

[garagelu]

ummm I'll just let other people help you because obviously you arn't listening to me.

[obsolete]

he's the only one trying to help. you just have your head up your ass

get a 3zx maf. and correct ecu.

[SR_Vlurs]

dude he's the only one trying to help you and he's given you some info you can use so stfu and listen

[garagelu]

Thanks for backing me up guys.

Ok here is another way of identifying the engine. Again this is still not a sure way. But on the zenki engines, the nuts that hold down the valve cover should be cap nuts. And on the kouki engines the nuts should be a regular open nut.

Again this is not a sure way because nissan does weird things. I have a ABS car and nissan put non abs calipers on my car. And sometimes the previous owner may have swapped out the nuts for different ones.

But you can take my info or forget it. And anyone that knows my info is wrong please correct me.

I know dude thanks alot man i appreciate you being the only person helping me .wish i could get more input though..i dont know bro i guess that if it realy is kouki or zenki i rather have it set up with all its corresponding parts .does anyone know if the plug on an "na" ecu is smaller that that of the "wc". I have a feeling i may already have the "wc" ecu and it might have been the "na" enclosure on it
