It's Porsche. Here's some info swiped from the Ultima GTR site:

In 1987, the G50 gearbox was installed into the Carrera 3.2 911. This
transmission used Borg-Warner syncromesh instead of the Porsche-
design balk-ring system to improve the shift quality and lessen the
effort required to change gears, especially from a stop. These
gearboxes were rated at 221 ft/lbs of torque. The G50’s have been
utilized with several variations of gearing and speeds. The 993
series was the first 911 offered with a 6-speed version of the G50
design. These later units also introduced significantly improved
clutch cooling.

Other versions of the basic design, called the G50/52 series, were
used in the 3.3 C2 Turbo and 3.6 C2 Turbo cars. These transmissions
also have stronger differentials and cases and a type of Limited Slip
differential that locks 20% under power and near 100 % on the overrun
to minimize trailing-throttle oversteer. All of the G50 cars use the
240mm clutch size introduced on the earlier Turbo cars and they are
now hydraulically actuated.
