Hi all, been a long time since I had an import (or a Subaru for that matter!), so a bit out of the loop now!

Considering a Twin Scroll BP5 Legacy, and wanted to get a bit more info around how they are typically converted when imported.

If the speedo has been adjusted to read in mph (so same clock, but a bit of tape over the k and a converter behind the dash), does this mean the odometer will also read in miles or is that a separate conversion?

If the converters convert both speedo and odometer at the same time, would standard practice be to adjust the odo from km to miles (i.e. adjust 100k km to 62k miles) or does it depend on the importer/individual?

I imagine this is a case of 'it depends' but got anyone who is more familiar with imports of this era what would you say is typical?

Just trying to understand if a car with say 100,000km on the clock is likely to be on 100,000 miles, 62,000 miles, or anywhere in between!

Thanks smile

I have a solder in chip in all three of mine , can be wired in behind the dash or off the gearbox speed sensor , the chips are around 40£ or so and come with instructions , ebay job as that's were I bought mine from , once it's plumbed in the speedo and odometer will read in miles from then on , and in effect the speed limiter of 112 mph is effectively cancelled out as you would have to go at 180 mph for it to cut in , clearly a non realistic speed , the clocks can be changed to show mph reading say if it was 100 k kph then it can be changed to 60 k miles , but I have never done that , I just write the kph down as the time it was changed
Thanks for the info - I guess unless you have the auction/import documentation, then it will always be a bit of an unknown.
