any one who has done this pm me and i add info

S13 speed sensor
 

here is a picture of a s13 speed sensor

I have the set up too I just need help doing the wiring. I already mounter my nx cluster in my s13. =D it is awesome that you are finally going to help out do this conversion.

take some pics on how it mounted....

I followed this link on how to mount it. All you do is cut the upper retaining plastic bracket and then the whole cluster slides in. Then you use 2 self tapping screws to mount the left and right holes of the cluster. Then, everything should fall in in place =D. now how did you do the wiring hehe I am in very need of your help.
#/f/tech-talk/337755...zenki-s13.html

if it works on the ka24de, that means it should work on an SR right?

thats right as long as you have the nx temp sensor and speed sensor then you should be good. All there is left the wiring and nurvcom made this dream come true

awesome I just saw the wiring diagram. I will install mines today and see how it looks like hehe. thanks nurvcom for all the great help.

yep if works on DOHC KA24de it work on SR20 and maybe rb20

That's tight. I think I might buy an S13 just so I can do this lol

I know both the de and sr have been covered, and I know this is almost completely custom, but would it be able to adapt to the ka-e? That has to be one of the best looking clusters Ive seen. great job and great write up.

likewise lol Nice write up

nice write up dude, big thanks to you guys!! but how about for s14?

if some get a cluster and harness and s14 cluster harness yes i would do one i did one for a guy for had s13 for 80

we could try anyone got a s13 sohc ka24e so i can test in Sacramento ca

I used a KA24E digital dash sub-harness to splice it into the NX one, it worked perfectly, so I don't see why not. I have a twin cam in my car, it used to be a single cam, but the speed sensor from a single cam tranny will make the speed read properly, and I did not have any problems using the twin cam temp sensor either.

Since this works with KA24DE and SR20, I assume the tachometer will not work with a KA24E. Am I right? Has anyone installed this on a KA24E?

Nice write up!

Your getting the tach signal from the dash wiring and the signal is not much different between the two so I assume it will work on both E and DE signal. My car was a E originally so all my wiring is single cam dash wiring. It should work.

hey
 

so now that I got the NX cluster hooked up in my car I am now going to try to wire up the HUD so it can work with the nx cluster. how to start. I saw that there are 3 wires that the hud uses. one gorund, one power and one signal from the mph gauge. I will try to hook it up this weekend and see if it worked.

If that was the case, then why doesn't SOHC tachs work with DOHC or SR motors? The interior harness is identical to both SOHC and DOHC. The signal however, is different. Do you think the signal is generated in the wiring? Something is sending the signal through the wires to the tach.. (duh). To my understanding, the signal comes from the CAS at the base of the distributor (i think).

Maybe this will help make the NX1600 cluster work for SOHC KA24

Tried this out using your write up and it didn't work. The two wire white plug green/white and red/black. The green is hooked up but where does the red/black one go? Also on the black nx plug it has two yellow/green wires and both are used so which goes where?

Depends on the year of the NX you got the cluster out of, you need to check on the back of the cluster where each pin goes because almost all of them are labeled on the printed board/flat wire on the back of the cluster. I think after 91 they are slightly different in the pin out.

yeh
 

hehe it is so funny how many people did this upgrade. This is awesome. :fart:

Your retarded and should stop posting.

Not much? Signal from wiring? Assume?

You do not get your signal from wiring... try again.

You know where I could find the pigtail. I've had my gauges from my nx2000 from a while back but didn't get the wires.

Would any other pigtails work?

ok this maybe a truly dumb question but how would you get this to work since Im doing a 1jz swap

this is pretty cool. too bad its not for s14 though..

Did any one else get this done? PM me please.

My bad, I could have worded that a bit better, I meant to say distributor wiring. But I do think your being a bit too harsh. Would you like to give us some insight on how to make it work for a singe cam?

Has anyone done this with a 92 nx? If so pm me please

I did it and I love the swap it is awesome. =D I also installed the heads up display rev gauge on my nx cluster
best swap ever =D

I'm still trying to get this thing in haha. Hit me up.

I looked on the back of the cluster but for the Black NX plug.. it doesn't show where it goes.. its just pins.. so can someone please let me know where each of the yellow/green wires from the Black NX plug goes.. as well as the red/black wire from the 2 wire NX plug.

Nurvcom I had another question regarding the wiring. you stated that in the s13 harness.. the center white plug has a white/black wire but i can not seem to find that in my sohc harness or dohc harness.. and that it goes to the red/black wire.. but then later later you put that you have to connect the red/black wire from the black s13 plug to the red/black wire from the white nx plug.. so do i connect all three of these together? sorry i'm just really confused here. would that be the pink/black wire (instead of the white/black as you stated) from the center s13 plug to the black/red wire (instead of red/black) from the white nx plug?

do i just guess which yellow wire from the yellow nx plug haha? there are 3 of them. there are alse 2 yellow green wires on the nx black plug.

if any one can get me the nx digital cluster and knows how to install in i will pay just say how much ..im in ontario cali.91761.....text me at 9098370134

Has anyone figured out how well it reads 3 digit speeds?

Is this accurate all around (gas levels, temp, speed, & tach?)
Is the tach much more responsive than the speedo?
Anyone try it with single cam temp sensor yet?

I am thinking of doing this for my s13 ka24e-t and figuring out the hud at the same time.

Also how is it backlit? I'm wondering if I can the bulbs with colored bulbs. I want to match my gauges

the gas level tach and temp are accurate on mine. i have a dohc temp sensor. the speed isn't because i still have a dohc speed sensor, i'm changing it out soon.

Hotness!!!

mad props that cluster looks dope

So, this CAN'T be done to an S14? I skimmed through and saw the post 'to bad not for an S14', thats about it. I have a spare S14 cluster/sub-harness and would just need to get the NX stuff. Would the SOHC speed sensor trip the CEL on OBDII models? I'd love to do this if possible without setting off a CEL for a P0500.

I just did it on mine as well and i love it. I had problems with the wires as well since i have a newer cluster with different color wires but i went through the wireing diagrams on both the 240sx and NX1600 and figured it out... pics and vid yo.....

http://i100.photobucket.com/albums/m...d/1e6edb58.jpg

the vid is not that great because its off my phone

Why is the cluster tripping out? lol

Its just its demo mode... you can put it like that to see if all the lighting woks
on mine, 2 of the RPM sections is out

Not a bad looking piece, but not fond of it enough to do it on my car.

Good job either way.

yeah... not for everyone but its a nice peace

I think i have the same newer cluster cuz i tried out the few write ups and they didnt work. Would you happen to have some of your notes you used to wire it together?

I still need to clean them up, but yeah... what do u need to know?

Basically what wire controls illumination on the nx cluster and what wire it connects to on the 240 cluster.

Basically what color wires get used on the nx and what they plug into on the s13.

Any info is greatly appreciated.

If you mean the onefor the dimmer swich on the nx cluster then its the red with blue stripe and it connects to the same red with blue stripe on the 240 center white plug... i belive its pin 42 on 240sx plug

Is the lighting Green or White?

They look white on the 1st page but green in your video and pix?

Its actualy green but it has a filter that aperantly turns it to white but i took it off so it would look a little brighter

im getting mine tomoorow wooo hopefully i can do it

Rev guage???

Do post pix!!!

I tackled this project over the weekend..

the wiring posted is close, but not exact, each NX cluster is wired the same, but the colors are different varying if its auto/manual, and year of production. my S13 wiring harness was also slightly differently colored (1991 240sx) I used the s13 FSM, and the NX fsm, compared wires, and then got both clusters, and both harnesses, and took it one wire at a time.

:::Notes of interest :::

-DOHC temp sending unit works perfectly (although cold is 2 notches above the c when cold, instead of right on the C), and the digital temp gauge reads much more accurately.
-DOHC Speed sensor reads DOUBLE, and if wired perfectly, will still maintain a 115mph speed cut, so that means you can go 56 mph, before the engine cuts.. which SUCKS. definatley need the sohc sending unit.
-Gas gauge is accurate
-tach is accurate


Ill let the pictures speak for themselves.

also, for any interested parties, this is a VERY accurate gauge of how bright it is during the day.

So can you use a SOHC Speed sensor on this cluster?

depends on what cluster u get
if im not mistaken the sohc sensor worx only for the 91-92...mine is from a 93 and it was reading doble with both the sohc KA and s13 SR sensor but fixed it and now reads right or 1.5 miles under what the cluster says

i would like to see someone take time out of their life to wire them up and put em up for sale... i wonder how much they would go for... nice shit though

i wouldnt mind doing it, its just they are getting harder to come by and to sell it with the wireing all done and proper speed sensor would probably cost upwards of $200 and not a lot of people are willing to pay that for a used cluster

Even with the proper vss I think it would cost closer to 300-350. 200 without the vss. Typical cluster can go for 60-100 then people charge 80-100 for the wiring. I did this cluster swap and really like it.
Alohaworld- check FOrumshawaii I had one for sale on there. No one wanted it so it's just collecting dust now

exactly my point, it gets expensive and no one wants to spend the money but it its a great cluster I love mine and everyone is always asking bout it and giving complements because its rare

i noticed that on the nx white plug the red/black wire is posted twice. it says

center white plug s13
s13 ~ nx
white/ blk ~ red/blk white plug



black s13 plug right side

s13 ~ NX
red/blk ~ red/blk white plug

so how does that work? do i do a triple solder?

any more close up pics of the fitment? looks like there's gaps on both sides. other than that, its definitely interesting.

Anyone have a better wiring thingy for this? There are three yellow wires on the yellow plug but which one is suppost to be used? LMK Thanks!

Is there s14 support for this or no?

Anyone know where I can find the NX1600 FSM?

my third s13 plug has 10 wires coming out of it, and this write-up only shows 6???

So the NX vss is plug and play? More info needed please...
I have my '90 tranny/harness ect. and it still reads double. Anyone tried just swapping the NX pinion onto the s13 speed sensor? $40 on Courtesy Parts.

I am going to pick up my cluster today and installing it into my RB26 Vert. I will be using my Dakota Digital converters tha I already have installed in the car to convert the Speed and Tach signal. I will try and post up the Dakota Digital settings once I have them all set up.

Time to bump this up! I've done all the research possible, except looking at the nx1600 fsm. I've got mine all wired up accordingly, but the clock is not working and my oil light stays on so I must have a crossed a wire somewhere. I'm using a single cam cluster harness which I'm thinking may have been the problem and if so I have a dual cam harness and a digi harness that i will wire in instead. My nx1600 cluster is from a 92. Does anyone have any info they would like to share to help me find out what I may need to do? Thanks


Sean.

sohc and dohc s13 cluster harnesses should be the same... the HUD harness is not the same.

what he ^ said...u just have a crossed wire

I figured. If the s13 harness is the same for kae and kade, then the nx1600 cluster wiring is a bit different? Something is not colored right, cus i've looked over it about 15 times trying to figure it out. Have any of you got one out of a 92 working properly?

I have... and you need to go by pinout not wire colors...
there are 4 different clusters and the wires do vary in color somewhat depending on model and year...
just go over your fsm wireing diagrams and you will find it

Ive been using both pinouts and colors. Either way I'm gonna take it back out soon and go over everything one last time. Thanks.

update: everything on the cluster functions properly, besides the speed still reading double. I've tried the single cam VSS and the nx1600 VSS but they do not fit in the hole where the dohc speed sensor sits. Ive tried taking the pinion off and swapping it, but that one is much bigger too. What VSS's are you guys using?

phuc
 

yeah i have the same problem..im lost let me know if anyone figures it out thanks

Would it be possible to use a dakota digital speed translator to get the speed right?

Universal Speedometer Signal Interface

on my current 240sx I using the nx1600 on ka24de auto and it reading good

I have the sohc vss and works perfect... I dunno

are u sure u dont have it in kilometers cuz it has kilo and mph? check that out cuz i have the same custer with the stock speed sensor and works perfect

guys, it all depends on the NX cluster you get, 91-94 there were 2 gens of clusters, and of those, there were 5 spd, and auto. only 1 of the clusters will work with the stock speedo.

nx1600
 

Ok here's what I'm.wondering... I just got the nx1600 cluster, I want to wire it into my 93 240.. its obviously dohc but it used to be auto and I got it swapped.. I would also like to know if wiring a hud would be possible.. hit me up with any info you got on my setup.. also I'm not sure what year or type the nx1600 is from yet so ill update when it gets to me... My email is [email protected] ..

(update)
 

The nx cluster i got is a 92.. so any updates on how the plugs are different from the original write up will help out.. thanks

I know this is a old thread but i'm so confused. You said green wire goes to blue and yellow wire from black and yellow plug. On my nx1600 cluster it has 3 yellow wires one from each plug and the yellow wires are connected into 1 yellow wire. So do I eliminate the other 2 yellow wires from the other plugs?

how high the mph can go? can it reach 180 mph ? Thanks....Omar

Ive taken it to 140 on my Sr with this cluster If that helps

cool thanks ,i guess it won't be a problem reading in the 180mph plus
last question you think is accurate? cause i don't like to be going around town with a gps also the gps is slow updating your speed
