When I was looking for a new speedo for my GTR a lot of people told me that I MUST buy the correct year speedo that fits my car. (89 mdl.) I found a full Nismo 320km/h cluster set on Yahoo Japan going cheap so I bought it. I was told it would fit an 89mdl. It didnt....

There is little difference in the speedo itself from what I can see. Just a revised version. Apart from the speed sensor. This little sucker controls how strong the power steering is VS the speed you are travelling.

If you got caught out with the different year speedo like me, this is how to swap the sensors around.

Tools needed:

A small phillips head screwdriver. (magnetic tipped would be a great help)

Yep thats it!

Now the fun part...

I'd recommend a really clean workbench or desk, a steady clean set of hands and a lot of patience.

Don't touch the speedo face as it leaves fingermarks on it and it's damn near impossible to remove them. There's clear plastic 'handles' on the sides of the speedo. I used them.

1 The 89 mdl speed sensor has 3 screws holding it onto the speedo. Undoing the top screw (closest to the face) will allow the trip meter to fall out. It doesnt matter if it comes off as its easy to put back on later. I removed mine on purpose so i didnt accidently drop and damage it.

Undo all 3 screws and carefully remove the sensor.

The 3 screws must stay with the sensor as they are longer then the other sensor's screws.

2 With the newer 90+mdl speedo, there is only 1 screw holding on the sensor.

You will need to remove the screw that holds on the trip meter to screw on the older sensor. The screw that holds on the trip meter will need to go with the newer sensor as its too short to hold the older sensor on.

3 Now it's just a matter of carefully putting the older sensor onto the newer speedo. I found it easier to put the single screw on the side opposite of the sensor on first, to hold the sensor while I was doing the fiddly screws on the other side.

The trip meter goes on first, then the sensor and finally the longer screw. When fitting the old sensor, you need to have 1 copper arm on each side of the tall gearing stalk.

Fit all 3 screws to the sensor and speedo and your finished.

I fitted the newer sensor to the older speedo and boxed it away in case i need it 1 day. The sensor wont get damaged like that.

Easy enough? If anybody has any questions or wanna add to this, feel free to PM me.

Cheers, Ron

do you think the sensor itself it repairable?

just a little bit of a late reply.

it would depend on what is damaged on the sensor. if things like the wiring is faulty, you could remove the faulty wire and resolder a new 1.

Since I wrote this, i've changed over a few more speedos. If people are worried about damaging their speedos but need to change over the sensors, feel free to PM me and i'll help you out.

any info on how to get the speed signal back to the ecu from the speedo on a r33 gtst ?

speedo is working but ecu is not getting a speed reading SO power steering pressure switch not working and also cannot use launch control on the VSS.

might have to open it up and have a look and wire it manually to the ecu?

    • Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.  
    • I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.
    • The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?
    • I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.
    • I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
