The 5.0-litre supercharged V8 is one of the highest-performance engines fitted to Range Rover and Range Rover Sport models. In the current engine catalogue, the supercharged 5.0-litre unit is represented by engine code 508PS, while 508PN identifies a naturally aspirated 5.0-litre V8. Because both share the same nominal capacity, engine code and vehicle specification must be confirmed before a replacement is ordered.
Our Ilford workshop handles diagnosis, rebuild and replacement enquiries for 5.0 V8 Range Rover engines. Cooling-system faults, timing noise, misfire, oil-pressure concerns, compression loss and supercharger-related symptoms should be assessed before deciding whether the engine needs targeted repair, cylinder-head work, a full rebuild or replacement.
The 5.0-litre capacity alone does not identify the correct engine. Send the registration and engine code so the supercharged and naturally aspirated specifications are not confused.
The Range Rover 5.0 V8 supercharged petrol engine is an all-aluminium V8 used in high-performance Range Rover applications. Land Rover literature documents the supercharged 5.0-litre V8 at outputs including 510PS in earlier Range Rover models and 550PS in Range Rover Sport SVR and SVAutobiography Dynamic applications. Our engine catalogue lists the 508PS engine as a 4,999cc V8 petrol unit.
| Engine code | Fuel | Capacity | Catalogue description |
|---|---|---|---|
| 508PS | Petrol | 4999 cc | 5.0-litre V8 supercharged petrol; our catalogue lists 372 kW / 506 hp |
| 508PN | Petrol | 4999 cc | 5.0-litre naturally aspirated V8; our catalogue lists 276 kW / 375 hp |
Output and calibration vary by model and year. The engine code, VIN/registration and vehicle generation should be checked together before a replacement is supplied.
Range Rover Sport applications include both naturally aspirated and supercharged 5.0-litre V8 derivatives, depending on model year and trim. The current catalogue lists 508PN and 508PS. High-performance SVR versions also use a supercharged 5.0-litre V8, but calibration and supporting components differ from lower-output versions.
Range Rover and Vogue models were also offered with 5.0-litre V8 petrol engines. The current rebuild page lists both 508PN and 508PS among Vogue applications. Registration-based matching is essential because cooling, supercharger, intake and electronic configurations vary across generations.
Higher-output performance models can use the same basic 5.0-litre supercharged architecture with different calibration and hardware. Do not assume interchangeability from engine capacity alone.
Rattle from the front of the engine, correlation fault codes or unstable timing can indicate wear in the chain, guides, tensioners or cam-phasing system. Timing noise should be investigated before it progresses into more serious internal damage.
The 5.0 V8 is sensitive to overheating. Coolant loss, pressure problems, water-pump issues, leaks from cooling components or repeated temperature warnings should be addressed quickly because cylinder-head and gasket damage can follow severe overheating.
Persistent misfire may be caused by ignition or fuel faults, but it can also indicate compression loss, valve damage, bore wear or head-gasket problems. Compression and leak-down testing help separate external faults from internal engine damage.
Oil-pressure warnings, bearing noise or metal contamination justify immediate investigation. Oil level, pressure, pump condition and bearing clearances should be checked before the engine is condemned.
Noise, reduced boost, belt-related problems or intake faults can affect performance without always requiring engine replacement. Supercharger operation and the intake system should be assessed separately from the engine’s mechanical condition.
The current Range Rover rebuild content identifies piston-ring replacement and cylinder-head skimming as typical high-mileage work on 5.0 V8 supercharged applications. The need for either should be based on measurement, compression results and strip-down findings.
| Route | Suitable when | What to confirm |
|---|---|---|
| Targeted repair | Fault is limited to cooling, ignition, supercharger, sensors or timing components without major internal damage | Engine mechanical condition and cause of fault |
| Engine rebuild | Original block and major components are serviceable but internal wear requires machining and new components | Measurements, cylinder condition, heads, crankshaft and oil pressure |
| Reconditioned replacement | Original engine has severe damage or replacement is more practical | Exact 508PS/508PN specification and vehicle compatibility |
| Used engine | A suitable verified unit is available and budget is a priority | History, mileage, compression, warranty and exact engine code |
Record overheating history, misfires, oil pressure, timing noise, cooling faults and supercharger symptoms.
Inspect pistons, rings, bores, crankshaft, bearings, cylinder heads, timing components, oil pump and sealing surfaces.
Check bore wear, head flatness, crankshaft condition and bearing clearances. Machine only where measurements support it.
Replace worn bearings, piston rings, gaskets, seals, timing-chain parts and other components according to the rebuild scope.
Reassemble to the correct 5.0 V8 specification, with timing and fastener procedures checked carefully.
Check compression, oil pressure, cooling integrity, fault codes and running behaviour before final handover.
Our workshop at 36-A Fowler Road, Ilford IG6 3UT can handle 5.0 V8 engine replacement enquiries from initial identification through to fitting and post-installation checks. This is useful on a complex supercharged engine because the original failure, cooling system and supporting components can be reviewed as part of one job.
If your Range Rover is already with another specialist, a correctly matched 5.0 V8 engine can be discussed on a supply-only basis, subject to availability and specification.
Where we manage the complete replacement, engine matching, removal, associated repairs, installation and final checks can be coordinated together.
We offer collection and delivery support across the UK. Send the registration, postcode and current diagnosis so transport and engine options can be included in the quotation.
A 5.0 V8 replacement is a high-value repair and cannot be priced accurately from engine size alone. Cost depends on whether the engine is 508PS or 508PN, the extent of internal damage, the availability of a replacement unit, supercharger and cooling-system condition, machining requirements and whether the job is supply only or fully fitted.
Rebuilt engines come with a 6-month warranty, and the exact terms vary by engine and work carried out. The exact parts, labour, duration and aftercare requirements should be confirmed in writing on the quotation or job sheet.
The 5.0 supercharged V8 is not a generic engine swap. Correct identification, cooling-system diagnosis, timing work, supercharger checks and post-fit testing all matter. Our JLR-focused workshop uses the vehicle registration and engine code as the starting point before recommending repair, rebuild or replacement.
Our engine catalogue lists 508PS for the 5.0-litre supercharged petrol V8 and 508PN for a 5.0-litre naturally aspirated petrol V8. Always confirm the exact vehicle specification before ordering.
The engine appears in Range Rover and Range Rover Sport applications, including higher-performance derivatives such as SVR and SVAutobiography versions. Output and supporting hardware vary by model year.
Yes, if the problem is identified before major internal damage occurs. A specialist should confirm whether the fault is limited to timing components or whether compression, oil pressure or internal contact has been affected.
Not automatically. The cooling fault, compression, cylinder heads and sealing surfaces need to be assessed first. Severe overheating can justify a rebuild or replacement, but some vehicles only need targeted cooling-system and head-related work.
Yes. Supply-and-fit enquiries can be handled through the Ilford workshop, subject to vehicle identification, engine availability and an agreed quotation.
Supply-only can be discussed where a correctly matched engine is available. The receiving garage should follow the required installation, cooling, oil and commissioning procedures.
Send the registration, mileage, current symptoms, diagnosis and engine code if known. That allows the workshop to identify the correct specification and quote the appropriate route.
