    Default Putting a 5.1 final drive in. Do I keep my JDM gears are go back to stock

    Hey,

    I currently have a mfactory 5.84 final drive and JDM gears in my UK ep3

    I'm taking the 5.84 out and putting a 5.1 in instead. Question is, do I keep the JDM 4th, 5th and 6th or do I go back stock?

    UK gears 70mph is 3500rpm
    JDM 70mph is 3700rpm I think

    I got a bit sick of driving on VTEC all the time on the road. It's a road car only. What you think?

    As it's apart I'd put an accord 6th gear In and leave the others they are.

    ETA- I'm not sure of the difference between a uk EP3 6th gear and the accord but I assume it'll be longer..

    Hey,

    According to this https://www.hybrid-racing.com/blogs/...smission-guide

    They are the same.
    Interestingly the FD2 has the same ration gearbox as the uk ep3 just with a 5.1 final drive. That's a JDM car with the euro spec gearbox (plus LSD)

    I went with a 5.1 Final Drive and 4th and 5th JDM gears with a Exedy OEM clutch and Mfactory Carbon Synchros.

    Feels awesome, not a torquey as the 5.84 but quicker of you know what I mean.

    Also installed a MJC Automotive Short Shifter too. Wish I;d fitted one of these years ago.
