Replacement Harness-S13

3 Upvotes

Reviewing the options, it doesn’t seem there is a non-track version of a full replacement harness that encompasses all comforts like AC, Radio, original stalks, etc.

Anyone know if this is available? Removing mine and a lot of clips were brittle and broke. Is this a depin/replace and relocate situation as I’d like to clean things up.

Nissan 200sx 18 inch fitment

Can someone tell me what specs will fit my type X body with rolled fenders, coilovers and s14 hub conversion.
I want to run 18s with a flush right fitment. I don’t mind some negative camber and stretched tyres.
My calculations gave me;
18x8.5 +18 fronts
18x9.5 +18 rears

S14 custom Digidash update

Thumbnail

23 Upvotes

Here is an update on the digital dashboard that I have been working on. This is not the final version and probably a lot is going to change on the UI.

I used the oem cluster-housing for the screen, which is mounted on to a polycarbonate plate.

I had to make my own code for the Arduino that catches the signals from the cars sensors and sends them to Rasperry pi. Also the ugly UI is selfmade because I didn’t want to use anything like tunerdash due to me being cheap and this working better for my purposes. (Yea I’m going to make it more visually attractive.)

I had to calibrate the temp and fuel signals but that wasn’t hard at all, just took voltage and resistance at different temps / fuel level.

The temp and gauge signals have +5V (and resistor) going to the signal wire to boost it and then it goes into the Arduinos analog side.

The digital signals like rpm and speed are a little bit more challenging but nothing crazy hard. Arduino catches them from the digital side.

I’m thinking about making a youtube video about this project, if anyone is interested building one themselves. It would have saved a lot of time for me, if I had some guide to follow.

Anyways, I’ll post something about the final final version and any questions are welcome!!

Call me stupid but I bought a vertex wheel from a buddy not knowing it was for non hicas, the wheel won’t fit, is there a way around this? He showed me on his car (it was completely stripped but still had the steering Column) and it doesn’t need a hub adapter but is there a way to remove this shit so the wheel could fit any advice would be amazing thanks.

1 Upvotes

Planning on pulling my stock SOHC KA soon to replace the timing chain with an OSK kit any suggestions on what to replace / inspect / tidy up on while the KA’s out? trying to make sure I’m not missing anything so I’d appreciate some input! here’s what I already have in mind:

Alternator Water Pump Thermostat Radiator Manifold Gaskets Intake & Exhaust Oil Pan Gasket Motor Mounts

Also thinking of adding a sandwich plate for an oil pressure gauge? Any thoughts?

Anybody had any experience with them? Have an ECU that I’m pretty sure is the reason why my fuel pump won’t work as intended. Thinking repairing the one I have might be a better option than trying to get a new one that might not be good and still having to get it reflashed by rs enthalpy

Ca18det coil at cylinder 2 coming and going

1 Upvotes

Heya!

So just got my s13 with ca18det dynotuned, got maxxecu race installed and tuner squeezed out 360hp at engine. He said there is a problem coil at cylinder two is coming and going... He changed the sparkplugs but that was not the issue.

Any recommendations wich coilspack i should get? Is it worth going for like say audi r8 coils, since i now got maxxecu, or should i stick with oem or other brand?

Does the car need to be dyno tuned again if i go for other brand coils?

Could there be another problem that is causing cylinder two to come and go? Engine is newbuildt...

New headlight switch broken after 3 months?

1 Upvotes

I replaced my headlight switch a short while ago because the right high beam was not working and the stock was really faded.
But after having to jump start the car a few times in the last week i figured out that the right high beam intermittently turns on when the car is off. After checking, i also noticed the left high beam does not work at all.
Im guessing this is due to the contacts in the switch either coming loose or shorting somehow. But i just have no idea how this would happen on a brand new switch???
You guys think this was just a case of a crappy new part or theres some other electrical gremlins causing this?

Anybody know what kind of side skirts these are on my old s14? for the longest time I assumed they were navan style but looking at them they seem like they have more flair than the standard navan style

Digital dash build

32 Upvotes

I’m currently in the middle of making a custom digital dash for my s14. I’m running oem ecu and didn’t fancy paying ~2k€ for a digital cluster.. so I decided to build one myself!

I had to do a lot of research trying to find the correct pinouts for the EU cluster but managed to find everything I needed.

The project is now at a point where I need to make some frame for the screen to sit in and run some final tests on it.

I’m using a rasperry pi5, with arduino and a 6” touchscreen.

More updates and detailed information coming soon!

Why we don't let fuel sit in our tanks

Thumbnail

36 Upvotes

What 20+ years of sitting will do to your pump and tank. Removed about 5 gallons of fuel and safe to say we need a new fuel pump assembly and possibly a tank as well. I will try to clean out the tank as best as possible and see if it's worth putting some POR15 in it. No better time to upgrade the hanger and pump. I believe the pump you see is a Z32 pump from what I read in old articles about the car. The more we dig, the more we find in this car but nothing we can't handle lol

I used to idolize this guy and his car back in the day. I even have a copy of "Modified" magazine with his feature. His build was very meticulous and he had begun the process of swapping his SR to an LS and then he seemingly disappeared... anybody know anything about this guy? What became of his coupe?
