I also like the idea of running a EVO final drive for acceleration. Especially if you plan to rev higher to hold a gear longer on the track. Hard part would be finding an EVO rear ring and pinion.


You can't match a DSM 2nd gear to an Evo1 input shaft. If you want to do this you will lose the evo1 1st gear as well. The evo1 1st and 2nd gear match the evo1 input shaft. Since the evo1 2nd gear is 0.5% taller, you won't even notice the difference between this and a DSM 2nd gear.

If the car was an evo it would make sense to change the final drive, but since we have the leisure of changing the gear ratios without changing the final drive, it's pointless. Both the evo3 3rd and 4th gear and USDM spec 3rd and 4th gear drop right into the trans to match the 91+ center diff without making any other changes.
