difference between turbo and non-turbo 5-spds?

Of what I know is that the turbo trans has a four gear forward planetary gear
set versus 3 gears for the non turbo.  It has a different valve assembly, torque
converter and flex plate.  Different plex plate because the turbo converter bolts
up to it in four places instead of three like the (NA box).   You might want to
check Bently of other differences.

Hope this helps.
