    Another half day of fight, I manage to replace both bearings on diff, to replace one side you need to undone big gear

    all washed and dried, with new bearing ready for assembly

    other side bearing have to be destroyed to remove

    then you have a little lip just enough to fit bearing removal tool

    Now need to source right size shims and it will be ready to fit, hopefully this weekend

    and there's current speed/rpms pictures, so far only 5th gear

    Have a first short drive with longer 1st 2nd and 5th, didn't notice anything on first two gears, maybe cos i didn't floor it as must wear in clutch first but 5th gear its different animal now, between 3-4k rpm its going from about 70 close to 100, im worrying about my license now.

    Longer Ratios fitted - my thoughts

    Nice hear some feed back on the changes you have made. Do a few more updates on the feel and how it has change over the next few outings, maybe post up the same picture of the speedo at different rpm like before.

    Of course you car speedo is in kph. Lol.

    As you wish Dave

    20160417_131701.jpg20160417_131733.jpg20160417_131833.jpg

    Today I do 'urgently' drive from stand still and it is different now, used to be like 1st bang gone 2nd bang gone 3rd a bit of hesitation and much slower rpm climbing up to go to 4th.

    Now 123 are very 'even', drop in revs feel great in between gear changes and car is, or at least feels much more sportier through this three gears, like constantly want to GO! GO! GO!
    Very happy with this mod.
    Anyone wants VERY short e8 box?

    The thoughts on this thread are similar to my own. The car doesn't feel any slower, the gears still feel well spaced. I would still like a longer 5th/final drive though - as you can see from Adams revs vs speed photos the difference is just not enough!

    Im not sure I would like to have even longer 5th, It doesn't looks like a lot from pictures but in real life its noticeable, car feels more 'civilised' on 5th now, kind of like my daily mazda 6, cruising 'at the edge of legality' on about 3250 rpm its IMO just bang on as in my case its where my torque start to peak and im on 200HP at this revs, what I find out now Im often touching driving licence BAN limit without realising it when b4 I can feel car its going fast, it used to was an 'event' crossing 100mph.

    Will post more later as I just driven it for about 60 miles, I want to see if fuel economy changed and it will be good chance to measure on way to and from japfest this weekend, stay tuned.

    this is an awesome read, I was hoping to do something similar cheaply, however looking at the lengths you've gone to I don't think that will be the case! while you had everything open did you ever manage to have a look and see if the v6 galant box bits were any good, I currently have an evo 4 box in and the gears are rubbish to say the least, I do have a whole 24v v6 galant that ive been cutting stuff from I have the gearbox so I was hoping to harvest that as I remember the gears felt like they changed at the right point, I really don't know much about gearboxes so any help would be appreciated, also a basic question, when I open the box do the individual gear sets actually have the ratio stamped on them or do I have to try look up the gearbox, ive looked up the evo box and it has a question mark on my box number !
