These are then converted to read in mph on import.There are a number of ways to do this.
You can simply fit a new clock face overlay going up to the equivalent speed in mph, ie 110mph.The speedometer mechanism is therefore unchanged, which means the odometer will continue to show the km traveled not the miles.
Alternatively you can fit a converter to electronically modify the speedo so that what was 180kph now becomes 180 mph, and simply put a mph sticker over the kph sticker on the speedo face.In this case the odometer will now read in miles.
Converters are usually fitted to the rear of the speedo cluster.
Either bolted on, or attached by wires.
If your original 180mph speedo was reading your speed correctly, it almost certainly had a converter fitted.
The 160 mph speedo you have now purchased most likely came from a UK na, and therefore should read in mph without the need for a converter.
But..
.
What you've not made clear is whether you have purchased the entire cluster and want to know if you can just swap this for your broken cluster, or whether you just want to swap the speedo unit over.
The na and turbo clusters arenot
interchangeable, but the individual instruments are.
So you should be able to just swap the speedo unit over, but will need to remove any existing converter for it to read correctly in mph.
I've not done this myself as I've always fitted JDM 180kph with an overlay or converter, but that is my understanding of the situation

1.Rev2 onwards as mentioned electronic
- above info on overlays, etc.
fit with what I've done on other Japanese imports.
2.I'm thinking of a genuine UK speedo
(as mentioned would need to change speedo clock in cluster as I'm told some of the converters upset the power steering
- urban legend?)

3.Turbo and NA use a different electronic speedo sender in the gearbox.
4.Speedo sender plug is 3 core into wiring loom
- trying to find out if the same on turbo or NA.

Based on part 2 I'm thinking of a UK speedo but think this means I still need to de-limit the speedo which can be done iirc.
