Jaguar F-Pace 400 SportENGINE OPTIONS

Every F-Pace 400 Sport is different. That's why we offer the right solution for your engine, your car and your budget.

01MOST POPULAR

REBUILDING YOUR F-PACE 400 SPORT ENGINE

Most engine suppliers sell you a used engine of unknown history and hope it matches. We rebuild the engine your F-Pace 400 Sport already has instead - strip it down, pressure-test it, and replace every worn or damaged component (timing chains, bearings and 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 F-Pace 400 Sport owners choose, and it's the one we'd recommend for most situations.

From £3,600
02

RECONDITIONED F-PACE 400 SPORT 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 F-PACE 400 SPORT 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 F-PACE 400 SPORT 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 AJ300P.

Learn more
05

REPLACEMENT F-PACE 400 SPORT 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 F-PACE 400 SPORT 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 F-Pace 400 Sport ENGINE

Jaguar E-Pace and Ingenium engine

The F-Pace 400 Sport was launched in 2022 as a special edition, distinguished by its use of the Ingenium AJ300P - a 3.0-litre inline-six petrol engine with mild-hybrid assistance. This is the same engine family as the standard F-Pace P400, but the 400 Sport carries the badge as a separate, high-spec variant. It's part of Jaguar's newer-generation six-cylinder Ingenium range, paired with a 48V mild-hybrid system for improved responsiveness and efficiency.

We continue to rebuild and replace engine engines for every F-Pace 400 Sport on the road.

Jaguar F-Pace 400 Sport ENGINE CODES

AJ300P

AJ300P

A 3.0-litre inline-six petrol MHEV fitted to the F-Pace 400 Sport from 2022 onwards (X761). The same Ingenium 6-cylinder pattern shared with the F-Pace D300 diesel and P400 petrol variants - we service it to the same standard as our other F-Pace rebuilds, replacing timing chains, bearings and gaskets as standard.

Jaguar F-Pace 400 Sport ENGINE COMPATIBILITY

Black Jaguar E-Pace in a workshop

The F-Pace 400 Sport's AJ300P is a specifically-tuned version of the 3.0-litre Ingenium six-cylinder. While it shares its core architecture with other Ingenium six-cylinder engines in the F-Pace range, its ECU calibration, power output (400PS) and mild-hybrid setup are unique to the 400 Sport badge. Before we quote or supply anything, we confirm:

Your exact engine code (AJ300P) via registration or VIN

Your generation (X761)

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