Searching for a Land Rover Discovery 4 engine 5.0 supercharged? Here is the straight answer first: Land Rover never fitted a 5.0 supercharged V8 to the Discovery 4 at the factory. The standard 5.0 V8 is naturally aspirated. The supercharged version went into the Range Rover, Range Rover Sport and Jaguar models.
That doesn't make the idea dead. Owners do swap, rebuild and tune these engines, and some want the supercharged power in a Discovery body. This guide covers the real specs, what a swap involves, what goes wrong with the 5.0 V8, and what it costs in the UK. When you're ready for a price, enter your registration on the RR Engine Works quote page and we'll confirm what suits your car.
Does the Discovery 4 Have a 5.0 Supercharged Engine, and What Are Its Specs?
The Discovery 4 offered several engines over its life: the 2.7 TDV6 and 3.0 SDV6 diesels, a 4.0 V6 petrol, the 5.0 V8 petrol, and in some markets a 3.0 supercharged V6 petrol. The Land Rover Discovery 4 5.0 V8 arrived around 2010 and is the most powerful engine the car left the factory with.
Most people searching the supercharged keyword are after one of three things:
- The standard 5.0 V8, assuming it was supercharged
- A 5.0 supercharged swap for more power
- Tuning to add power to the existing engine
All three are covered below, so you can jump to the one that matches your plan.
What Is the Difference Between the Discovery 4 5.0 V8 and the 5.0 Supercharged?
Both are the same 5.0-litre aluminium V8 family from Jaguar Land Rover. The supercharged version adds forced induction, uprated internals and cooling, and a different engine management setup. Here is how they compare on paper:
Feature | Discovery 4 5.0 V8 (NA) | 5.0 Supercharged V8 |
| Induction | Naturally aspirated | Roots-type supercharger |
| Approx. power | 375 PS | Up to 510 PS |
| Approx. torque | 510 Nm | Up to 625 Nm |
| Factory fitment | Discovery 4 | Range Rover, Range Rover Sport, Jaguar models |
| Typical owner goal | Daily use, towing, smooth power | Maximum performance |
Figures are manufacturer approximations, so check them against JLR documentation for your exact model year before you rely on them.
The supercharged engine is not a bolt-on upgrade. The ECU, cooling, intercooling, fuel system and drivetrain all matter, which is why swap quality varies so much between workshops.
How Fast Is the Discovery 4 5.0 Supercharged From 0-60?
A standard Discovery 4 5.0 V8 gets from 0-60 in around eight seconds, which is quick for a heavy seven-seat 4x4. The Discovery 4 is also much heavier than a Range Rover Sport, so a swapped car won't match the 5.0 supercharged figures quoted for those models. Expect a clear improvement, but treat any exact time as an estimate until the car is tested.
Weight, gearing, tyres and tune all change the result. Be wary of anyone promising a precise 0-60 before the work is done.
Is a 5.0 Supercharged Engine Swap or Tuning Worth It for a Discovery 4?
For some owners, yes. For many, a well-maintained or reconditioned standard 5.0 gives better value and fewer headaches. The right answer depends on your budget, how you use the car, and how much risk you're comfortable with.
What Does a Discovery 4 5.0 Supercharged Swap Involve?
A proper swap is a project, not a quick fit. These are the main areas of work:
- Engine and ancillaries. The supercharged unit, its intercooling and supporting hardware need to fit and work together.
- ECU and wiring. The engine management must be matched to the car, or you'll chase fault codes.
- Cooling. More power makes more heat, and the Discovery's cooling system must cope.
- Gearbox and driveline. The ZF automatic and driveline must handle the extra torque.
- Brakes and suspension. Stopping and handling should match the new performance.
- Legal and insurance. Tell your insurer about the modification. If the engine type changes, update the V5C with the DVLA, and check emissions and MOT requirements.
A common mistake is buying the cheapest supercharged engine without checking its history. A tired unit with a worn supercharger or a damaged timing chain can cost more to fix than a sound engine would have cost to begin with.
Swap vs Tuning vs Reconditioned Standard 5.0: Which Is Best for You?
Option | Cost Level | Reliability | Work Involved | Best For |
| 5.0 supercharged swap | High | Depends on the donor engine and fitting quality | Extensive | Performance-focused owners |
| Tuning the standard 5.0 | Low to mid | Good if done properly | Moderate | Modest gains without a swap |
| Reconditioned standard 5.0 | Mid | Strong, with warranty | Straightforward fit | Reliability and daily driving |
Our usual advice: if your goal is a dependable Discovery that tows and travels, a reconditioned standard 5.0 is usually the sensible choice. Choose a swap only if you want the extra power and accept the extra cost.
What Are the Common 5.0 V8 Problems to Check Before You Buy or Swap?
Whichever route you take, know the weak points. The most frequent Land Rover Discovery 4 5.0 problems we see are:
- Timing chain and guide wear. Worn guides can cause rattles and, left alone, serious engine damage.
- Oil leaks. Gaskets and seals can weep as the engine ages.
- Coolant leaks. Hoses, the thermostat housing and the water pump are common culprits.
- Misfires. Often caused by ignition parts, injectors or an engine management fault.
- High fuel consumption. The V8 is thirsty, and a sudden jump can point to a fault.
These checks apply to any 5.0 you're considering, supercharged or not. Ask for service history, listen to the engine from cold, and have the car inspected before you commit.
A real-world scenario: an owner buys a cheap 5.0 supercharged engine for a swap and later finds timing chain wear. The extra strip-down means paying for labour twice. A pre-purchase inspection would have avoided it.

How Much Does a Discovery 4 5.0 Engine Cost, and Where Can You Buy One in the UK?
Price depends on whether you choose a used engine, a reconditioned unit or a full swap. Used engines are cheaper up front but carry the most risk. Reconditioned engines cost more and usually come with a warranty. A swap costs the most because of the extra parts and labour.
When you search for a Land Rover Discovery 4 5.0 V8 for sale in the UK, you'll find breakers, online listings and specialist workshops. Cheap listings often hide unknown mileage and no warranty. Always ask about testing, warranty terms and what is included before you pay.
