Range Rover Classic Cylinder Head - Diesel
Diesel Engines
Diesel engines were introduced as an option for the Range Rover in April 1986.
The first diesel engine fitted was the (Italian) VM 2400 4-cyl, which was turbocharged and intercooled for the Range Rover application. This is essentially the same engine as fitted to the Rover SD1 saloon from 1982 onwards, except that the slightly lower powered SD1 engine was not fitted with an intercooler.
In October 1989, the 2400 TD engine was replaced by the 2500TD, which is a longer stroke version of its predecessor. Vehicles fitted with VM turbo diesel engines were only available with manual transmission.
In November 1992, the VM 2500TD engine was replaced by Land Rover’s own diesel unit, the 200Tdi, which was already fitted to the Discover and Defender.
In March 1994, the 200Tdi was replaced by the 300Tdi. Like the VM engines, the 200 and 300Tdi are (2500cc) 4-cyl turbocharged and intercooled diesels. Unlike the Italian diesels, however, they are direct injection engines.
Only the 300Tdi was available from Land Rover with automatic transmission.
