haha you got me, never raced my sentra because it was the base model version, cough cough... and yes asking how to switch a tach and speedo to make yourself feel like you have a wrx is stupid, because you dont even need a tach in your car its an AUTOMATIC.... give up kid, you bought every wrong option on an impreza if you wanted it to be fast, I mean this in the nicest possible way. Just do suspension mods and you will love it, you will probably beat WRX's all day at autox because you have a free hand for the hand break, dont have to worry about shifting, and your mad skillz will be shown.
