The BCNR33 GT-R version also had the same "RB26DETT" engine that the BNR32 was equipped with, although torque had been improved, due to changes in the turbo compressor aerodynamics, turbo dump pipe, and intercooler. The turbo core changed from a sleeve bearing to a ball bearing, but the turbine itself remained ceramic, except on N1 turbos (steel turbine, sleeve bearing). From the R33 onward, all GT-Rs received Brembo brakes. In 1995 the GT-R received an improved version of the RB26DETT, the ATTESA-ETS four-wheel-drive system, and Super HICAS 4-wheel steering.
