- | # Different size tires than original, changed diff ratio or transmission | + | |

- | <blockquote><hr>I think you'll find this is caused by poor/dirty ground strap from the engine to the body inside the engine bay. | + | It is normal for the speedometer '''to read fast'''. The specified tolerance is +5% -10%. So at actual 60mph it can read 57 to 66 and still be acceptable. But you can blueprint the speedometer to be closer to the actual speed. |
- | It only takes once, and the cable it screwed, as it melts the nice polyethylene coating on the inside. | + | {{Main|Speedometer Calibration}} |

- | * If speedo reads too slow, fit a smaller cog | + | |
- | Given that stock is a 17 tooth pinion, moving to one more or less tooth is about 6% change. So by changing the pinion you can only get it to ±3 mph accurate. For example, at 100 mph, within 3 mph. Or at the standard 50 mph rating, a reading between 1½ mph (48½ to 51½) is the best you can hope for. For finer tuning the speedometer itself needs calibration. Or you could fit different diameter rear tires. | + | = Alternatives = |
+ | Possible fit: [{{Post|132123}} Smith's guage from a Triumph] | ||
+ | <br>{{Album|10754}} | ||
- | EXAMPLE: If you are reading say 60 when you are really going 50 then the speedo cable needs to slow down by about 20% to read more accurately. If the speedo drive has a 17 tooth cog in it try to find a cog that reduces by 20%. 17 X .20 = 3.4 teeth... 17 + 3.4 = 20.4 teeth, the closest is a 20 tooth cog. | + | VDO |

Current revision
Speedometers were either in kilometers or miles. Australia started with mph and then switched to kph via sticker overlays. Some speedometers had a trip meter.

The odometer has five digits as shown by this 2006 unit:
When the count exceeds 99999 it turns back to 00000.

Metric-Imperial Conversion
Sometimes on eBay Australia you can get the vintage conversion stickers.
OR
print this on plain paper at 125%, for a test fit. If you like it, print on sticker stock then apply to the speedometer
OR
Take the face plate and scan it on the flatbad scanner, then modify it. Finally, print a new one out with the photo printer. You can modify the font, colors, etc. You might think you can simply bolt it to the speedo using the standard screws, but it will not lay flat. Adhesive paper (sticker paper) will work
Speedometer Calibration
It is normal for the speedometer to read fast. The specified tolerance is +5% -10%. So at actual 60mph it can read 57 to 66 and still be acceptable. But you can blueprint the speedometer to be closer to the actual speed.
Speed Buzzer
Starting in 1972, all JDM speedometer came with speed switch for warning of excess velocity.
Amplifier Speed Switch
1972 Japan, Australia late utes and 1973 USA used a speed switch.
Alternatives
Possible fit: POST Smith's guage from a Triumph
220km/h coversion from Matsuoka-M
Custom Faces
Z Speedometer
280Z speedometer fits in the 1200 dash cluster.
- Swap the mounting cups as the 280Z unit is deeper
- Drill a hole for the trip meter shaft through the back
- The face is to large for the opening in the 1200 housing, so carefully reduce the diameter by 1/8 inch
350Z speedometer looks a similar size.
Electronic Speedometer
Yes, you can fit an electronic speedometer into a 1200.
