1983 Datsun 280ZX L28ET Borg Warner NWC T-5 Manual Transmission designated as FS5R90A
The 1983 Datsun 280ZX Turbo came with the Borg Warner NWC T-5 Manual Transmission designated as FS5R90A. This transmission is tougher than the FS5C71B.The increased horsepower with the new 2.8L Turbo motor, from 132 HP to 197 HP, required a beefier transmission. (L28ET : L28 = 2.8L E= Electronic Fuel Injection T= Turbo). The Borg Warner Non World Class transmission was designed to fit many car makes and models, by using a different bell housing. Most images leave the bell housing out.

The S30 and S31 models are different and are not compatible, the Input shaft is longer and I think a different diameter output shaft.
