Bugeye/Frogeye and 3.7:1 Differential

Got a pumpkin problem? Want to change gear ratios? This is where to go.

Bugeye/Frogeye and 3.7:1 Differential

Postby bbob » Tue Sep 13, 2005 9:33 am

Hi all,

I'm currently running a standard 948cc frogeye with the standard 4.2:1 differential. I want to change the differential to improve the cruising but don't think that a 3.9:1 diff will give much improvement so am considering a 3.7:1 diff. I am concerned that the car won't have the enough power for this diff. Does anyone have any experience of such a change or of any other differential ratio changes.

Thanks for your help.

I run a standard 948cc and have recentlyadded the 3.9 diff gears. As I also have a Datsun 5 spd trans, the performance is still a little bit spritely.
I worried about that a bit before the change but I'm good with it now. As to 3.7 gears with a 4 speed? ?
Let us know how it comes out.
