R33 Speedo inaccurate after gearbox conversion

Hi,

I converted my R33 from auto to manual a while ago, and since I did it, my speedo has been reading just under half of what it should be, ie at 80 it says around 40 etc.. I am guessing this is because the senders are different? Obviously the auto sender wont fit in the manual gearbox, so I am screwed there...

I have been asking a few of the local gearbox shops around town, but I have had no luck as yet, because frankly, they seem to be a bunch of w@nkers who just dont want to know about it. Out of frustration I have bought a speedo corrector from here (see link below)

however hooking it up to either of the 2 wires that come from the sender on the gearbox does not work... I am guessing I will need to install the speedo corrector on the wire that goes from the ECU to the gauge, but then my HICAS etc will still be out as the ECU will think I am doing half my actual speed even though the gauge is reading correctly. I would prefer not to do this if at all possible.

Can anyone shed some light on this, or has anyone done this before? I am at my wits end and I'm about to go kick the neighbours dog out of sheer frustration, or possibly cos I am too stupid to work this out....

Any ideas would be greatly appreciated....

If you can find out the correct point in the cluster, it should be a matter of changing the voltage, which will change the speed shown.

In the older R31 it's a matter of installing a potentiometer to replace a certain resistor in the cluster. That way you can adjust the calibration however you like. .. http://wiki.r31skylineclub.com/tiki-index....ter+calibration

I am not sure whether it will be so easy in R33, but you could look into it.

I just got a manual cluster put into my car and now the speedo is alot more like the real speed. Its only out by around 8 kms at 110kph. I just rang a place in perth that can adjust speedos and because it is a electronically spent unit then they are gonna have to change to gearbox speedo gear and the cheapest is $150 and going up to around $350 depends on which one is required. So the question is wether to put up with the slight variation or find another cheaper way to adjust it slightly :cheers:

anyone got any other ideas ?

I now have the r33 manual ecu too. that didn't seem to change anything though.

      Turn signal wiring question

      Convert to dual filament bulb   FWIW, it will look odd - I dare say a bit dumb as it looks like your flasher relay has shit the bed.

      Possible swap on R34 RB20DE NEO?

      If the RB20 box in the car is a push clutch, then yes, you will need to deal with the pull clutch on the turbo box. You either buy a pull clutch and don't use the old one, or you do the things needed to convert the turbo box's clutch arrangement over to push. Which is a bit of a f**karound. "Making" a custom tailshaft is the easy part. But you will need to source the front clip yoke - the bit that goes into the output of the gearbox. These are not as easy to find. They are out there, but they don't grow on trees the way that they used to.

      Indicator bulbs are way too bright to use as a "corner marker" (we call them parking lights too). Sure. Go ahead and do it. But realise that you wil need to come up with all your own wiring to do it, as no-one will have a standard howto worked out for Skylines. It's just a matter of abandoning everything that Nissan have done and starting from scratch. You'd probably be better off retrofitting tailght/brakelight globe bases into the front indicator housings and using the taillight circuit for your corner marker and the brake light as the indicator. You'd need to work out how to kill the marker circuit while the indicator is flashing, otherwise it won't flash on-off, just bright-less bright.

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance
