If you remember the GZ, RZ and SZ, then the new Japanese spec trim levels on the A90 GR Supra will be familiar: RZ, SZ-R and SZ. Previously, the GZ was the full optioned version of the RZ twin turbo model while the SZ-R was the fully optioned version of the naturally aspirated 6 variant. With the A90 the RZ represents the 3 liter turbo 6 engine and the SZ-R and SZ carry the 2 liter turbo 4 motor. Without further details we would assume these engines would be some variant of the B58 and B48 power plants all coupled to the ZF 8HP automatic transmission.At the bottom of the page it also hints that the US market will only be getting the SZ, and the RZ and SZ-R trims will be exclusive to Japan.
