I have a 2000 OBS

Is there a difference between OBS MT and RS MT. I've been looking for ratio chart for OBS or even the basic Impreza:bonk:. My OBS trans is on it's the way out. Wont to upgrade, Is It worth putting RS in or just go with one like I have. I have lots of mods lined up for this car.

Cool that's what I was looking for. And my car has 4.11 LDS from factory. The RS trans doesn't look like a vary close gear ratio. But I have one lined up for a good price it well have to do for now.

Definetly seems to be a 3.90...


Although that number you provided doesn't seem to be listed, however the two closest are 3.90.
