As with any vehicle, there are many ways to improve the performance of a Land Rover TDI 300. Some are fairly inexpensive and straightforward; others require more expertise and expense. One consideration when reviewing options for performance enhancement of your Land Rover is the inverse relationship with engine longevity and gas mileage. Simply put, adding power and performance requires increasing the amount, and purity, of fuel to the engine. This can potentially shorten the life of the engine and will most certainly impact fuel efficiency.

Skill level:
Moderately Challenging


  1. 1

    Determine your budget for making modifications to your Land Rover TDI 300. Some performance enhancement techniques can get fairly expensive while others can be done at home for the cost of a few parts and with some mechanical know-how.

  2. 2

    Increase the pressure in the diesel injector pump to raise the level of diesel fuel and boost performance. Some installation high performance diesel injector kits claim an increase in engine output of as much as 60 horsepower.

  3. 3

    Replace the standard viscous coupled fan with a performance rated electric Kenloe fan. The viscous fan standard on the Land Rover TDI 300 requires up to 10 per cent more power to operate. Upgrading to the electric fan will result in more air passing through the engine with less power required to do so.

  4. 4

    Replace the standard air filter and intercooler system with a higher grade, performance model. Improved air circulation allows the engine to "breathe" easier and work more efficiently, improving the overall performance.

  5. 5

    Increase the compression of the cylinder heads as well as the gear ratio to boost power and acceleration. An increase to the compression may impact the reliability of your engine, so if you are not familiar with the impact of this type of modification, talking with a trusted mechanic beforehand is suggested.

  6. 6

    Swap the standard turbo for a high performance model for perhaps the most dramatic, and costly, enhancement to performance. Unless you are an SAE-certified mechanic, this is a job best left to the professionals.
