From what I have gathered in my endless quest for information on AUDI based gearboxes, the O1E is based on the 083 944 turbo box. (which is a modified 016) It shares the slightly larger ring gear and front pinion bearing and has a wider 3rd gear. The later ones had a wider first gear.
One thing i haven't figured out is why they moved the differential cover to the opposite side. This now puts the differential load on the cover instead of the case. Maybe for ease of assembly?
The early O1e''s had a problem with pinion bearings and it seems to be the concensis that this was caused by improperly set preload at the factory. (although the factory hasn't admitted it)
The O1e should be comperable to the 944 turbo (083) outside of ratios. The 944 turbo (083) has been used successfully in many v8 powered 944's. One of which has an LS1 with a Magnason supercharger and over 500 lbs. ft. of torque at the rear wheels. This car is a part time track car with no transaxle problems. There is another with a highly modified Buick Grand National turbo v6 with just under 600 lbs. ft. of torque at the flywheel which also has no problems. This car isn't a track car. Neither of these guys do drag race starts but do drive hard. These are just two examples.
My pinion is that the O1e is stronger than the 016 but does not have good ratios.
