    Faulty Speedo Reading

    My speedo is off by about 10kph. When I allegedly travel at 120kph at 3700 RPM, I am actually going 110. Anyone else have this issue?

    comparison of Canadian manual gear ratios to U.K./Euro ratios

    5-speed manual transmission ratios

    Canada
    1.6L, 4-cyl, 109 hp
    UK
    1.2L, 3-cyl, 80 PS
    naturally aspirated
    UK
    1.2L, 3-cyl, 98 PS

    supercharged
    1st 3.727 3.727 3.727
    2nd 2.048 2.048 2.048
    3rd
    1.393 1.393 1.393
    4th 1.029 1.097 1.029
    5th 0.821 0.892 0.821
    Reverse 3.545 3.455 3.545
    Final drive ratio 4.055 3.438 (14 in. wheel)
    3.563 (16 in. wheel)
    3.438

    Source: UK Micra brochure from http://www.nissan.co.uk/GB/en/tool/b...new-micra.html

    So the Euro version gets the lowest gearing for best fuel economy, even with smaller engines.

    People interested in the fastest acceleration in all gears should combine the Canadian final drive with the gear ratios from the UK's 1.2L naturally aspirated Micra.

    Even the lowest power 1.2L UK Micra revs lower in top gear than the Canadian Micra.

    People interested in the best fuel economy should combine the Canadian (or UK supercharged) gears with the 3.438 f.d. from the 1.2L naturally aspirated Micra.

    Interesting information.

    So, this means that the Micra at 100 kmh is ~2930 rpm. If you'd go to the UK final drive, it would drop down to 2485 rpm while cruising.

    That would be a big gain! At the expense of acceleration in all gears, of course.

    So does anyone know the transmission model code?
    Is it the same as the versa? Im trying to figure out if theres a LSD we can use.
    Can I assume based on the post above that we share the same tranny as the UK 1.2supercharged ?
    That could mean we could use the nismo one.

    I never did find a code anywhere. If you look up the ratios of the Versa Note / sedan though, I'm pretty sure you'll find they're a match. Maybe that info can be found on the Versa forums.

    EDIT: I don't think the Euro tranny necessarily matches ours. I just posted that to compare the ratios of the Canadian car vs. theirs. For one thing, our Micras don't even have any shared engines (only 3-cylinder engines in the Euro K13).
