Toyota GZ engine

The Toyota GZ engine family consists of a single model, the 1GZ-FE, which Toyota used as the powerplant of the second generation Century limousine from 1997 to 2017. The 1GZ-FE is a 4,996 cc (5.0 L) 48-valve DOHC V12 with variable valve timing, a bore of 81 mm, a stroke of 80.8 mm and a 10.5:1 compression ratio. The official output advertised in Japan under the gentlemen's agreement is 206 kW at 5,200 rpm, though export markets advertised 220 kW, and peak torque is 481 N m at 4,000 rpm. The electronic fuel injection is run by two ECUs, one for each bank of six cylinders, and the engine can keep running on either bank if there is a malfunction. A 1GZ-FNE version runs on compressed natural gas. It replaced the V8 in the Century.
