Injector 095000-8981; injector 095000-1550; gasket set CGK6UZ1; starter M009T62371; piston and liner kit; cylinder head; common rail pump; VGS turbocharger; water pump; oil pump; overhaul kit.
Capacity stayed the same at 9,839 cc. The change is in the fuel and air system: high-pressure common rail injection with a VGS turbocharger and charge air cooling replaces the mechanically governed pump used before.
Because the machine family spans two generations. Headings for this class pair the larger six-cylinder engine with the earlier ZX450-3 and ZX470LC-5, while a used unit identified as 6UZ1-XASA-11 is recorded out of a ZX470LC-6. The generation decides which engine is under the hood.
Two references are traded: 095000-8981 with 095000-8982 and 8-98167556-1 alongside, and 095000-1550 with 8-98259287-0. The units taken out of the machine carry the answer, and the neighbouring number for the larger engine differs in the closing digits only.
Published figures are 362 hp at 2000 rpm with maximum torque of 1436 Nm at 1500 rpm.
