The torque from a zetec turbo kill even cts boxes when driven in anger

I've heard using a frs box is harder than a nomal mtx

I heard it's the speedo drive being digital and it has a rear starter motor.
also has cable shift
I know someone that had the internals from a frs box put in a mtx so he could use selector, speedo cable and front starter

Ring OddKidd mate because he sells the shafts and mount kits
