Identifying S14 blacktops

Post by **maxpower** » Thu May 01, 2003 4:03 am

Hi, I am shopping around for a kouki blacktop and I want to be certain the motor I am to buy came from a late-model s14. Aside from reading the tag/id inside the engine bay, are there any other signs to look for on the engine itself?

..because I would rather buy a s13 blacktop over a zenki one and save a nice chunk.

s13 valve cover is black, totally flat (no slant in the back by firewall), and doesnt have a vtc lobe on the front of the motor, lol, pretty obvious

to summarize my first post: I need to know how to tell if the engine came out of a s14 kouki or a s14 zenki. thanks.

common sense would tell you why spend 3600 on a early-s14 blacktop when you could spend 1000 less and buy a s13 blacktop of teh same year. This is what i meant to say in that last bit I added at the end of my post.

ANYWAY, are there any markings on the motor that tell the year?

Im still confused.....do you want a s13 motor or a s14 motor? S13 blacktops did not come in s14 cars, they came in s13 180sx Type X.....the S13 didnt have Variable timing .....the S13 does not visually look the same as the S14...so you dont need "markings" you just need to look for the lobe for the VTC....i dont understand what your asking....

thanks for the mini faq.

There are two motor sets in front of you. Both engines pulled from a S14 Nissan Silvia. How do you tell which of the two engines was taken out of a 97-98 Silvia (kouki).

Post by **I H8 UR DSM** » Thu May 01, 2003 4:03 am

They will both be S14's...neither will be an S13 blacktop, i can gaurantee you that.....beyond that, im sorry, cant tell you how to distinguish between two s14 motors which one is newer(there is no other difference between those motors, besides milage, and month of manufacture)

sorry

you figured out how to make my head hurt, lol

MAX... you are one confusing kid.. Are you saying you want the newest S14 motor you can buy?

If you have the clips in front of you.. then just go by the headlamps.

thats what i thought, but then it said he wanted to save money by getting the s13 motor : )

You know i think he is trying to give someone a headache. lmao

You can't find out the years for them. There were no significant changes to the engines between those years.

Post by **maxpower** » Thu May 01, 2003 4:03 am

alright, here's the extended cliff's notes version of my first post.

I want the newest s14 blacktop motor to go into my car.

Since there are two types (i'll refer to them by zenki and kouki), I cannot tell if i am getting a 1995 motor with 75k miles or a 1998 motor with 25k. I will be keeping it in stock form; so, rebuild, replacement of internals or anything of that nature is VERY unlikely to happen. this is why it is important that the engine i buy is a low milliage late-model kouki engine.

What I said at the end about buying a s13 blacktop motor instead, meant that if the supplier sent me a 1995 high milliage zenki, I will be at a loss. because a s13 blacktop (1996) sells for ~1000 less and will be in the same condition (ignoring the difference in design between the two).

capiche?

Now, I know that there is atleast one difference between the two engines (back to zenki and kouki). Nissan does not sit on its *** for 3 years - they make revisions to a car based on TSBs and whatever else... for example, the cooling fluid reservoir tank is shaped differently in the usdm 96 and 98 240sx. Actually, there is even a slight difference between the 97 and 98 models.

get it out of a clip...that way u have the gauges (i.e. odometer)

Post by **I H8 UR DSM** » Thu May 01, 2003 4:03 am

:fried:

Post by **maxpower** » Thu May 01, 2003 4:03 am

i don't trust many people. Most claim all of their engines have less than 30-40k miles, yet they cannot tell me the exact milliage. If this is something that is checked at the wreckers in japan, how can i trust some of those goons, to them it's just another 300 dollar pos.

another thing ..a well known reseller sells clips with up to 70k miles on the engines, and the pricing is insane. asdfklajfh!! i'm building a wooden raft and going to import my own clip someday :/

lastly...many clips don't come with gauge clusters (I wonder why?!?!)...not everyone sells clips (like HT and AD-T) and any one with some common sense can swap the odo with another one or roll it back.

OMG all this rambling make my eyes hurt. To answer the question... There IS a difference in the Kouki and Zenki motors. The internals were upgraded from the Zenki to the Kouki, meaning they can withstand more abuse, higher output, hence longer lasting. From what i remember, the Kouki has the same internals as the s15 as well. If I were to do a stock motor swap with bolt-ons, i would def buy the Kouki. If I were to pop open the motor and do internals, i would save the $$ and go s13 motor...

To answer the rest of the question about identifying the Kouki from the Zenki motors, From what RockSco had told me, there are more verticle ridges casted into the head of the Kouki, i dont have any examples, but I am sure Rock may jump in here any time to follow up.

uhhh... because it comes with a t28! :rolleyes. I just purchased an s14 kouki clip from neishlin motors with 35k mi on it and the gauge cluster included with those miles on it. I know some people package phony low mileage clusters with their motors, but neishlin is for real. They provide pics of the ID plate on the clip with the years, VIN#, etc and multiple angles of the clip as well as close ups of the intercooler and other parts most sellers won't even include. When you buy a clip, it should have that plate on it. If it doesn't, I'd be suspiscious. That is why I chose to pop the extra coin to buy from them, because you know exactly what you're buying. Nice guys too.http://www.neishlinmotors.com

AFAIK the internals are the same in both the s14 engines.

There are a few differences between the engines but neither one is better.I could be wrong cos the european engines are not the same as the jdm ones but that is mainly because of the emissions.

You could ask this question on the UK sxoc forum.All the people there have either the ca18det or the s14 sr20det!! http://www.sxoc.com

Yea B.L.....i have no idea where that kid got that info from, lol....but i figured let them believe what they want ya know...i tried helping him for a whole page, and now its up to him to figure out what he wants to believe...lol....

And about the ridges on the front...yep my motor has those....Oh but its not even an S14!

Only way to tell between a 95-96 sr20det and a 97-98 sr20det is that

95-96 sr20det has studs on the head, so you have to use nuts to bolt down the valve cover like the redtop s13's .97-98 sr20det has bolts to bolt on the valve cover rather than nuts.

You can check the ECU tooECU code for the 95-96 is WCECU code for the 97-98 is NA

Both of these are in 5spd ecu

hey DSM... that was good...hahaha, that kid must not have a clue about these motors. Oh wait, you were refering to me... crap!

I MUST be wrong, cause Ruffles have ridges, and its not even a motor!!

Look for the "cooling fins" looks like ridges on the motor that're facing the front of the car. You'll see horizontal lines.
