I've gone quite the opposite direction, actually. My car turns 3500 rpms (more or less) at 70mph. But I didn't build it for the highway.
i mean that most people are using early imprezas that came with low power motors originally. because of the low power they had pretty short gear ratios that kept the rpms up so that it had the power to move properly. a high torque eg33 doesnt need to run at 4000 rpm on the highway, probably like 2500. i know that at least one of the 5spd swaps for svx's comes with a longer 5th gear so that it can run those low rpms on the highway.
so i was wondering if anyone had used a gear like that in place of their 5th gear so that they can have good cruising gas mileage.
