My dirt track ep3 needs alittle more speed in second gear. It needs to reach 77 in 2nd gear to be hitting rev right before the turn. Currently it will hit 65 and bigger tires won’t increase it enough to help. My plan is to change the 4.764 final drive in the 5 speed to a 4.0-4.2 aftermarket final drive. The internet has them but they seem to all be marketed towards the RSX-S 6 speed. My question is, will an aftermarket final drive for the 6 speed work in my ep3 trans? One marketed towards the ep3 are much more rare.
