ABOUT THE
JAGUAR AJ133 (AJ-V8 Gen III) ENGINE
The AJ133 - also known as the AJ-V8 Gen III - is Jaguar Land Rover's 5.0-litre V8 petrol engine, produced from 2009 to 2024. It's one of the most significant engines in Jaguar's modern history, appearing across six model lines from the XF and XJ through to the F-Type and F-Pace SVR. The engine is available in both naturally aspirated and supercharged forms, with the supercharged version delivering between 470 and 575 horsepower depending on application. The naturally aspirated variant, used in earlier XF, XJ and XK models, produces 385-470 hp. The highest-output variant, the AJ133S, is found in the F-Pace SVR and XFR-S, producing 550-575 hp.
JAGUAR AJ133 (AJ-V8 GEN III)
APPLICATIONS BY MODEL
Across the F-Pace, the AJ133 appears exclusively in the SVR variant (X761, 2016-2024) with a supercharged tune producing 550 hp. The F-Type uses the AJ133 in both R and SVR variants (X152, 2013-2024), with the same supercharged V8 delivering between 550 and 575 hp. The XE saw the AJ133 only in the limited-production Project 8 (X760, 2018-2020), the most extreme application of this engine. The XF uses the AJ133 in the XFR and XFR-S (X250, 2009-2015), with the XFR-S receiving the higher-output AJ133S tune. The XJ carries the engine in Supersport and XJR variants (X351, 2009-2019), while the XK uses it in the XKR and XKR-S (X150, 2009-2014).
JAGUAR AJ133 (AJ-V8 GEN III)
ENGINE COMPATIBILITY
Because the AJ133 spans six different models and multiple generations - and because it exists in naturally aspirated, supercharged, and high-output SVR tunes - compatibility comes down to confirming your exact model, generation, and powertrain spec, which we do by registration. A supercharged AJ133 from an F-Pace SVR isn't a drop-in match for a naturally aspirated AJ133 from an earlier XJ, even though the base engine code is the same. Ancillaries, mounting, ECU calibration, and supercharger tune all vary by model and year. Before we quote or supply anything, we confirm your exact vehicle.

OUR WORKSHOP VIEW OF
THE JAGUAR AJ133 (AJ-V8 GEN III)
Built, rebuilt and tested by engineers who work on Jaguar engines every day.
Here's our practical view of the AJ133 (AJ-V8 Gen III) across its F-Pace X761, F-Type X152, XE X760, XF X250, XJ X351, XK X150 applications.
APPLICATIONS WE SEE:
The AJ133 is one of the highest-performance engines we work on - spanning six model lines from the XF and XJ through to the F-Type and F-Pace SVR, in both naturally aspirated and supercharged forms.
WHAT WE REPLACE:
Timing chain components, bearings, and gaskets as standard on every rebuild, with supercharger coupler replacement included on supercharged applications. Cooling system components are inspected and replaced where required.
KNOWN ISSUES:
Early AJ133 engines (2009-2012) are known for timing chain tensioner failure - the tensioners and guide rails were not strong enough, and early engines with 15,000-mile oil change intervals are most affected. Cooling system leaks are also common, with pipes, hoses, connectors, and water pumps all documented failure points. Supercharger coupler wear is a known source of rattling noise. These are confirmed issues we inspect for on every AJ133 rebuild.
AJ133 (AJ-V8 GEN III) REBUILD INFORMATION
Typical rebuild scope:
A TYPICAL
JAGUAR AJ133 (AJ-V8 GEN III) REBUILD
The following describes a typical rebuild scope for this engine - illustrative of the work involved, not a specific customer job. Real case studies from our own completed work will replace this section once available.
The AJ133's timing chain system is a known critical wear point, particularly on early engines (2009-2012). We inspect it thoroughly on every rebuild. The supercharger sits on top of the engine and must be removed to access the valley where the oil cooler, timing chain, and other critical components reside. Plastic coolant pipes and heat exchangers are known failure points and are inspected during strip-down. Full engine replacements require DME software matching.
01INSPECTION & STRIP-DOWN
Careful inspection of the crankshaft, cylinder head, and timing chain components during strip-down.
02COMPONENT REPLACEMENT
Main bearings, connecting rod bearings, gaskets, seals, and timing chain components replaced as required.
03QUALITY CHECKS
All major rotating assemblies, oil pump, and cooling system components inspected for long-term reliability.
Typical Scope:
Timing chain components, bearings, gaskets, supercharger coupler (where applicable), cooling system inspection, DME software matching

JAGUAR AJ133 (AJ-V8 GEN III) REBUILD VS REPLACEMENT VS USED
Rebuilding Your AJ133 Engine
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your Jaguar already has instead - strip it down, pressure-test it, and replace every worn or damaged component with updated OEM parts. You get a near-new engine with a 12-month unlimited-mileage warranty, without the compatibility risk of an unknown used unit. This is the option most AJ133 owners choose, and it's the one we'd recommend for most situations.
- Strip down & inspect
- Pressure-test
- Replace worn components
- 12-month unlimited-mileage warranty
Replacement AJ133 Engines
If your existing engine is beyond economical repair, we also offer full engine replacement and fitting - sourced and fitted by our team, with the same 12-month unlimited-mileage warranty.
- Supplied & fitted by our team
- OEM quality
- 12-month unlimited-mileage warranty
Used AJ133 Engines
In some cases, a matched low-mileage used engine is the right call - particularly if you need your car back on the road quickly and your existing engine's damage is extensive. We can source and fit these too, though most owners who ask about used engines end up choosing a rebuild once they understand the compatibility risk a used unit carries, especially given how many different AJ133 applications exist across the Jaguar range. Enter your reg below and we'll talk you through both options honestly.

Reconditioned, Refurbished or Remanufactured?
JAGUAR AJ133 (AJ-V8 GEN III) RECONDITIONED ENGINES
"Reconditioned" is the term many owners search for when they mean the same thing as a rebuild - a full strip-down, inspection, and replacement of worn parts rather than a straight swap. If that's what you're after, our rebuild service is exactly that.
→ Our rebuild service is exactly that.
JAGUAR AJ133 (AJ-V8 GEN III) REFURBISHED ENGINES
"Refurbished" often describes the same process from a different angle - restoring your existing engine to full working condition rather than replacing it outright. Our rebuild covers this.
→ Our rebuild service covers this.
JAGUAR AJ133 (AJ-V8 GEN III) REMANUFACTURED ENGINES
Some owners specifically search for a "remanufactured" engine, expecting a unit rebuilt to original specification with updated components. That's consistent with what our rebuild service delivers, regardless of which of the six AJ133-equipped models you drive. Jaguar AJ133 Reconditioned, Refurbished & Remanufactured Engines Terminology Explained: Rebuilt: Existing engine stripped, inspected and rebuilt to original specification. Reconditioned: Broad industry term; we define our rebuild as a full strip and rebuild. Remanufactured: Usually implies a defined restoration process; our rebuild meets this standard. Used: Existing engine from another vehicle; we can source and fit these. What Jaguar Garage Means by "Rebuild": Full strip-down, inspection, measurement, machining where required, replacement of worn components, reassembly, testing, and refit - with a 12-month unlimited-mileage warranty.
→ That’s consistent with what our rebuild service delivers.
