does anyone know what the internal is on the mi2ec if i'm using the 20t pulley?

The EC only has only one pulley size and the internal is 1.8:1, which you can see on page 28 of the EC instruction manual here.

Seaball, when you mentioned it is "20T", is that something different then the typical Mi2EC..? All my Mi2EC were 20T center pully (U3010) and in that case, the internal is 1.8 same as Mi3 and Mi3.5.

The Mi2 had an option of putting a 17t pulley and giving you a larger ratio.
Not an option on the EC because the pulley system changed(front and back belts unite at this point).
The Mi2 you took the pulley support and reversed it, the length away from the back diff would change, therefore the geometry of the pulley changed.
Hope that helps, and clears anything up....

Internal is as everyone has said 1.8.
