is s13 red top wire harness same as s13 blacktop wire harness?

[junk240sx]

just curious in case engine is toast and have to get a new one. whether it'll just plug right back in and work regardless of year of s13 engine.

i've heard there are a few differnt wires but not sure.

[getnrowdy23]

i think there is only a couple of different wires, but not positive. call heavythrottle and ask them

i'm using a blacktop engine and harness with a redtop ecu with no problems.

Some of the colors of the wires are different, but they are still all pinned right. The Kouki blacktop S13 harness may have a couple more differences.

[junk240sx]

what years are kouki engines? I thought kouki wasn't sr20det but ca18det.

[SpeedRacer1]

1989-1990 = S13 CA18DET1991-1996 = S13 SR20DET Redtops and early model blacktops.1997-1998 = S13 SR20DET (Kouki) later model blacktops.

Zenki loosely means "early"Chuki means "middle"Kouki means "last or latest"

So on S13 chassis, 1989-1990 S13's are zenki. 1991-1996 are chuki (this depends on the country your in though). 1997-1998 S13's are kouki.

[junk240sx]

so any wiring difference between the 'chuki' 91-96 redtop or blacktops? If same, I want to buy a newer (closer to '96) chuki blacktop to replace my red top that's going to die...

speed, nice reference but how do I tell which blacktop I have? i don't have the ECU that came with the clip. I'm using a redtop ECU.

[daz1320]

i think you may have an early model blacktop.i think the later uses a j7 ecu.i have an earlier blacktop and I used to run a 62 until I got my E5.Both ecu's were run using a redtop harness.

[SpeedRacer1]

The kouki blacktop S13 SR20DET (1997-1998) runs off of a different ECU as mentioned.

If you try to run a kouki model blacktop off the #62, #63, E5, or E6 ECU's, only the first cylinder will fire. These ECU's can be used on a kouki blacktop but the wires need to be repinned.

So if your blacktop is running off a redtop ECU then its from a 1994-1996 180SX.

Here are the different ECU's for the S13 SR20DET:#62 manual redtop#63 auto redtopE5 manual early blacktopE6 auto early blacktopJ4 manual later blacktopJ? auto later blacktop

I just went tru this crap this year. I started off with a 95 blacktop and it blew due to a bad oil pump. Now running a redtop. Like they said, as long as you can verify the year of your blacktop, you can run a redtop in there with your blacktop harness and ECU. Check the ECU to verify that you have an E5. Personally id recommend you to source a redtop. Preferably and AUTOMATIC redtop. Less abuse than the 5 speed for the most part. Stay away from blacktops since if you think bout it, they all came from 180sx, whens the last time uve heard of a grandpa drive a 180sx and drift it? You have a better chance of getting ahold of a redtop thats taken care of than a blacktop.
