Jaguar XJ8ENGINE OPTIONS
Every XJ8 is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR XJ8 ENGINE
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your XJ8 already has instead - strip it down, pressure-test it, and replace every worn or damaged component (timing chain, tensioners, valve seals, gaskets) 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 XJ8 owners choose, and it's the one we'd recommend for most situations.
From £4,500RECONDITIONED XJ8 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.
Learn moreREFURBISHED XJ8 ENGINES
Similarly, "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.
Learn moreREMANUFACTURED XJ8 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 on the AJ-V8.
Learn moreREPLACEMENT XJ8 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 warranty.
Learn moreUSED XJ8 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. Enter your reg below and we'll talk you through both options honestly.

ABOUT THE Jaguar XJ8 ENGINE
The XJ8 was a key part of Jaguar's XJ range through the late 1990s and 2000s, offering V8 power in a more accessible package than the supercharged XJR. It used the naturally aspirated AJ-V8 engine across two generations - the X308 (1997-2003) and the X350 (2002-2009) - with capacities ranging from 3.2 litres to 4.0 litres depending on the market and specification. The AJ-V8 was Jaguar's first all-new V8 design, and while it's a robust engine overall, timing chain components and valve seals are common service items at higher mileage. The XJ8 is no longer in production, but we continue to rebuild and replace engines for every one still on the road.
We continue to rebuild and replace AJ-V8 (naturally aspirated) engines for every XJ8 on the road.
Jaguar XJ8 ENGINE CODES
AJ-V8 (X308, X350)
A naturally aspirated V8 fitted to the XJ8 from 1997 to 2009 across two generations. The X308 generation used the 3.2-litre and 4.0-litre versions of the AJ-V8, while the later X350 generation continued with the 4.0-litre AJ-V8 before being replaced by the 4.2-litre unit in some markets. We replace timing chains, tensioners, valve seals and gaskets as standard on every AJ-V8 rebuild.

Jaguar XJ8 ENGINE COMPATIBILITY
The XJ8 spans two chassis generations with the same engine family, but there are differences between early and later AJ-V8 units. Before we quote or supply anything, we confirm:
Your exact engine code via registration or VIN
Your generation (X308 or X350)
Your engine capacity (3.2L or 4.0L)
Any ancillary or ECU variations specific to your exact build
This is why we always start with your registration rather than a generic XJ8 quote - it protects you from paying for parts that don't fit your actual car.
