Jaguar XJ Super V8ENGINE OPTIONS
Every XJ Super V8 is different. That's why we offer the right solution for your engine, your car and your budget.
REBUILDING YOUR XJ SUPER V8 ENGINE
Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your XJ Super V8 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 XJ Super V8 owners choose, and it's the one we'd recommend for most situations.
From £5,500RECONDITIONED XJ SUPER V8 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 XJ SUPER V8 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 XJ SUPER V8 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.
Learn moreREPLACEMENT XJ SUPER V8 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 XJ SUPER V8 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 XJ Super V8 ENGINE

The XJ Super V8 was the flagship petrol model of the X350 generation, produced from 2002 to 2009. It used the supercharged 4.0-litre AJ-V8 - the same engine family that powered the XJR of the same era, tuned for the XJ's more refined character. The X350 was the first XJ to use an aluminium monocoque chassis, significantly lighter than previous steel-bodied XJs. The XJ Super V8 is no longer in production, but we continue to rebuild and replace engines for every one still on the road.

The XJ Super V8 uses a single engine family across the X350 generation - the supercharged 4.0-litre AJ-V8. Before we quote or supply anything, we confirm:
Your exact generation (X350)
Drivetrain and ancillary specification
Any electronics or ECU considerations specific to your exact build
This is why we always start with your registration rather than a generic XJ Super V8 quote - it protects you from paying for parts that don't fit your actual car.
