are T50's used? split case modified? bearing upgrade? straight cut gears?
or is it just a TRD close ratio upgrade?

All AE86 in Group A used the T-50 gearbox and T series rear end. I believe there were three sets of gear ratios homologated for Group A AE86.
Quaife straight cut with 1st gear 2.3ish and 5th gear 1:1. This was used in Australia by the works team and some top privateers.
There was also a TRD close ratio with 2.3ish 1st gear, 1:1 4th gear and 0.88 5th gear. This is in my car, which was rented by many privateers for the ATCC and Bathurst 1000 in Group A.
Std gearbox was also homolgated of course, but no one used it.
