There are many reasons to replace the engine of your Series Land Rover and there are many engines to choose from! Some are good and some not so good. I have a 1976 Series pick-up that had a standard 2.25 petrol engine. It has fantastic 4x4 capabilities but on the road it is as slow as a donkey. To get an engine to give you a good cruising speed and have good 4x4 ability, you need a TDI or a powerful petrol engine!

Let’s look at some good and bad reasons!

Bad reasons

1. More power. Choosing the wrong engine (V6, V8, or 6-in line) will break the gearbox and diffs.
2. Fuel economy. If you fit a 300TDI you will never break even. The conversion cost versus fuel saving doesn’t make this a viable option. 300TDIs are expensive!

Good reasons

1. Better cruising speed.
2. More power, without damaging the drive train!
3. Cheaper and more available spares.
4. Diesel. No wet plugs or distributor!
5. Fuel economy!

Things to take into consideration before doing a conversion:

1. Air filter and hose. It is best to replace the Landy filter with a Donaldson! It has better airflow and filtration! You can then also fit a snorkel.
2. Radiator and hoses. Landy radiator will not do the job for some engines! You will have to fit a bigger one with an electric fan controlled by a thermo switch! This will give the engine better temperature control!
3. Intercooler. For a turbo diesel! It in not necessary to fit an intercooler, but it will give you more power and better fuel economy!
4. Engine Mountings. For some of the conversions, engine mountings will have to be manufactured to specification.
5. Exhaust. Will have to be custom made according to the conversion that has been done on the Landy.
