So guys i have 2 of the Precision Converters that TEP sells, one is the standard converter and one has the Billet back cover. They are both 3000 Stall but one is made for a SC application and the other is made for a Turbo Application.
Anyway thought not too many people have the opportunity to have these next to each other to take the pics.
all of the pics the Billet cover is on the left
i can say the one with the Billet Cover is heavier and looks much different than the regular or the stock unit.
