Sport Ka ratio's are just like XR3i ones, nice and close! The 1.3 Ka is loooong like a diesel box......... but it's what you prefer really.
The gearing in the none turbo diesel box's are not long they are shorter than a standard rst. mine soon whips throu them at faster than it did with the turbo box. and is quickly maxed at the limiter in 5th
