Jaguar XJ 3.0 V6 SuperchargedENGINE OPTIONS

Every XJ 3.0 V6 Supercharged is different. That's why we offer the right solution for your engine, your car and your budget.

01MOST POPULAR

REBUILDING YOUR XJ 3.0 V6 ENGINE

Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your XJ 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 owners choose, and it's the one we'd recommend for most situations.

From £3,200
02

RECONDITIONED XJ 3.0 V6 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 more
03

REFURBISHED XJ 3.0 V6 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 more
04

REMANUFACTURED XJ 3.0 V6 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 AJ126.

Learn more
05

REPLACEMENT XJ 3.0 V6 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 more
06

USED XJ 3.0 V6 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 3.0 V6 Supercharged ENGINE

Jaguar E-Pace and Ingenium engine

The XJ 3.0 V6 Supercharged uses the AJ126 - a 3.0-litre supercharged V6 petrol engine. It was fitted from 2013 to 2019 across the X351 generation of the XJ, which ran from 2009 to 2019. The AJ126 is a derivative of the AJ133 V8, effectively a V8 with two cylinders removed, and shares much of its architecture. The XJ 3.0 V6 was introduced as a more efficient alternative to the V8, offering strong performance with lower running costs. The XJ 3.0 V6 is no longer in production, but we continue to rebuild and replace engines for every one still on the road.

Jaguar XJ 3.0 V6 Supercharged ENGINE COMPATIBILITY

Black Jaguar E-Pace in a workshop

Because the AJ126 is a specific engine code used only in certain XJ models, fitting the wrong replacement - or assuming a V8 part will work - risks a compatibility problem. Before we quote or supply anything, we confirm:

Your exact engine code (AJ126) via registration or VIN

Your generation (X351)

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 quote - it protects you from paying for parts that don't fit your actual car.
