Engine Power Specifications

This list started when I was researching engines for the 1999 Green Rover engine swap.  Since then I've just updated the page as I come across engines that would be potential donors for Land Rover transplants. These numbers were taken from multiple sources and I do not testify to their accuracy. I do think that they are interesting though. Note power levels should be thought of as stock average.  These numbers varied from year to year of production and go up with the addition of goodies.

When considering an engine transplant, weight should be considerd to be an important factor.  It affects how well the suspension works and how the vehicle handles in off road conditions.  Picking an engine close in weight to the Land Rover 2.25 engine means you affect the suspension and handing the least.

Note #1:  Rover 6 cyl engines  From Dr James Taylor  "The 3-litre version was designed FIRST, for the 1958 (1959 MY) Rover P5 3-litre. They needed 3 litres because the car was competing higher up the market than the P4, and they needed 7 bearings to improve smoothness for that market. So the bore centres were repositioned and it ended up as very different from the original 2.6 IOE engine (2638cc) in the P4.

The short-stroke engine (2625cc) was developed from the 3-litre as an improvement (smoothness, also manufacturing cost) over the earlier 2.6. Rover did try the 3-litre in Land Rovers but found that the high torque could cause transmission problems and that the fuel consumption was higher than they wanted. So they went for the 2.6.

The original 3-litre and 2.6-litre engines were upgraded with a water-heated inlet manifold and other modifications in 1962. These are known as the Weslake-head versions because tuning expert Harry Weslake was consulted­ although Rover engineers insist that most of the design changes were their own. All the 3-litre saloons went to the Weslake-head engine because they needed the extra performance. The Rover 95 (P4) kept the 100 engine (give or take a few tweaks) and the new 110 took on the Weslake-head 2.6. There were also very small numbers of 2.6-litre (and even 2.4-litre) versions of the Weslake-head engine used in the 3-litre body for overseas markets.

The NADA 109 Station Wagon was the ONLY Land Rover to use the Weslake-head 2.6 engine. All other six-cylinder models used the earlier (Rover 100) engine, although improvements were made to this over the years until production ended in 1979-80. The Weslake-head engine was fitted for the US because Rover North America's head, Bruce McWilliams, insisted that Americans wanted the extra performance."

Some conversions:

1.00lb-ft = 1.35 NM

1.00 HP = 0.746 KW

1.00 sq. inch = 6.452 sq. cm

1 mile = 1.61 KM

1 KM = 0.621 Mile

1 US gallon = 3.78 L = 0.833 British gallon

1 L = 0.264 US gallon
