![]() Paradoxically, this was a high-maintenance engine that would withstand utter neglect. This arrangement was the norm for the time and produced a relatively quiet combustion noise, though standing next to one of these engines on tickover might convince us otherwise. This indirect injection engine featured pre-combustion chambers, one for every cylinder, fitted into recesses in the head, in which the fuel and air was mixed before reaching the real combustion chamber. It may be a throwback to the Series III and earlier, but this is the so-called 2.3 engine (actually still 2286cc), the stronger and allegedly smoother unit, thanks to having five main bearings instead of the early version’s three-bearing crankshaft. Whichever one we think is best, the choice inevitably comes down to personal experience and preferences, and what you think a Defender should be. Maybe it’s the engine that lasts the longest, the most reliable, the cheapest to repair, the easiest to work on and how do fuel consumption and emissions figure in all this? Over the next few pages we’ll take a detailed look at these engines. The old 2.25-litre petrol engine is quieter and smoother than any of the diesels, it might not have sparkling performance, but do we need that in a utility wagon? And what does ‘best engine’ mean? There’s plenty of criteria to consider: power, torque, smoothness, quietness, best noise, best puller, most tuneable, best tow engine. These early machines started out with the 2.25-litre engines from the Series III which, could only be described as agricultural, with noise, vibration and aroma being their major characteristics, so we should delete those from the running right away. Or are Tdi engines just noisy, slow, underpowered and outdated examples of exactly how bad an old diesel can be? I’m looking at 14 engines that have been fitted into the Defender range, and I’m including those fitted to the pre-Defender Ninety and One Ten models. On the other hand, surely the dependable old 300Tdi that can be fixed in the field and never breaks anyway, was the ultimate powerhouse. But is it a real Land Rover engine or is it a concocted answer to European emissions regulations with scant regard for the real needs of an off-road truck? Maybe this final TDCi is the most powerful, torquey and refined engine ever, even if it is a Ford unit. Compatible Gearboxesįits the LT77 as standard, but can fit the R380 with a shorter R380 Bell housing.It should be a no-brainer that the latest and last 2.2-litre TDCi is the best-ever Defender engine. The Defender version fits easier than the Discovery's. Convert to the 200Tdi EngineĬan be a good option for a Series Land Rover, which gives an impressive performance boost and has the same gearbox. ![]() Convert from the 200Tdi EngineĬonverting to 300Tdi or Td5 is possible without upgrading the LT77 gearbox, although doing so and replacing it with the R380 will make an easier fit. 200Tdi service kitĬheck out this list of items that are required as a "service kit" for the 200Tdi. ![]() In real terms, there is not much to separate the engines in terms of performance, whilst the parts and systems they use can vary widely. People have been known to downgrade from a 300Tdi to get the benefit of better fuel consumption. Since the 200Tdi engine can be placed in a variety of Land Rovers through the years, and fact that they were only produced for 4 years means that they are sought after engines and demand a higher price accordingly. The Discovery version also produces a bit more horsepower (111hp). The Defender and Discovery versions are different - they have different front covers, manifolds and the turbo is located differently (Defender: above inlet manifold, Discovery: below inlet manifold). Considering that the 200Tdi was only built for 4 years and the 300Tdi for 12 years, spares are harder to find on this older engine. The 200Tdi is also reputed to have better engine durability and has a lower fuel consumption than the 300Tdi. The 200Tdi is very similar in power to the 300Tdi, however the 300Tdi is a evolution of the 200Tdi so is considered more 'refined'. There was also a new cylinder head, turbocharger, intercooler and direct injection system. The Land Rover 200Tdi engine replaced the 2.5TD and 2.5NA engines of the 90/110, with a new strengthed engine block to rectify the 2.5TD's problems.
