My answer was stuffed if I know so I said I would ask the list. Therefore can anyone tell me what changes Toyota made to my 1HZ. ???? Jon G'Day Jon, From the technical books,: Slight change in Compression Ratio. [of no real concern] Shape of the pre-combustion chamber changed/enhanced. Combustion chamber in piston and piston changed. Weight of the flywheel is increased. Injector nozzle orifice has been increased. New type glow plugs and changes to the relays and resistors that control these. Hydraulic automatic tensioner [belt] Resulting in: 96kW at 3800 instead of 4000 rpm as previous. 285 Nm at 2200 instead of 280 Nm at 2000 rpm.
