my mate is having a k24 bottom end, and k20 top end installed in his dc5r

he already has the k20a type R gear box.


question is, which box would be better for k20/24 engine? the k20 short geared box, or k24 long geared box.


Some have said, the k20 box will be too short for a higher powered/torque engine.


All feedback appreciated.
