"Wanted a V8 conversion done right, not a bodge job. They talked me through compatibility and the ECU mapping before touching a spanner."

Custom Conversion
Full Compatibility Check
An engine swap isn't the same as a standard replacement. Rather than fitting a like-for-like unit, we fit a different or upgraded engine — a V8 conversion, a diesel-to-petrol swap, or a Defender running a different platform entirely.
Done properly, this means real compatibility work: engine mounts, wiring, ECU mapping and DVLA notification all need to be handled correctly, not assumed.
We walk you through what's legal, what's involved, and whether a swap genuinely suits your goals before any work is booked in — so the decision is an informed one.
Start with your registration number for an instant estimate, then speak with our team about the engine you have in mind and whether it's a straightforward or a more involved conversion.
Once agreed, we collect your vehicle from anywhere in the UK, remove the existing engine, fit and adapt the replacement unit, complete any necessary ECU remapping, and confirm the DVLA notification process before handing your vehicle back.

Discovery, Defender and Freelander models are assessed for TDV6, TDV8 and alternative engine options, with mounts, wiring and ECU mapping adapted properly rather than forced to fit.

Range Rover, Sport, Evoque and Velar models can be matched with V8 or diesel-to-petrol conversions across the AJ133 and Ingenium ranges, with full compatibility checked before any work begins.

Jaguar models sharing engine platforms with Land Rover and Range Rover benefit from the same sourcing knowledge and remapping expertise, including guidance on any IVA testing implications.
Our technicians carry out engine swaps regularly across Range Rover, Land Rover and Defender platforms, giving us a level of compatibility knowledge most general garages simply don't have.
That experience covers ECU remapping, engine mount adaptation and DVLA notification, meaning fewer surprises and a finished result that drives properly from the first mile.

Technical Expertise
ECU & DVLA Guidance
Wherever you're based, our nationwide collection service brings specialist engine swap and conversion work within easy reach, without needing to travel to Essex yourself. Your vehicle is collected, the swap carried out at our Grays workshop, and fully tested before being delivered back to you ready to drive.

Request A QuoteWhat is the difference between an engine swap and a replacement?
A replacement fits the same engine your vehicle originally had. A swap fits a different or upgraded engine — such as a V8 conversion or a diesel-to-petrol change — which involves extra compatibility, wiring and ECU work.
Is an engine swap legal in the UK?
Yes, provided it's carried out correctly and, where required, the DVLA is notified of the change. Some conversions may also need an IVA test. We advise on the exact requirements for your specific swap before work begins.
Do I need to notify the DVLA of an engine swap?
In most cases, yes — particularly if the swap changes the engine size, fuel type or power output. We guide you through what needs reporting so your vehicle remains correctly registered.
Can I put a different engine into my Range Rover?
In many cases, yes, but it depends on the donor engine and your specific model. We assess compatibility across mounts, wiring and ECU before confirming whether a swap is a sensible option.
How much does a Range Rover engine swap cost?
Cost depends on the engine you want fitted, the complexity of the conversion, and any ECU remapping required. We provide an instant estimate from your registration, followed by a fixed quote after inspection.
Is an engine swap cheaper than a standard replacement?
Not always — a swap can cost more than a replacement due to the extra compatibility and remapping work involved, but it can be worthwhile if you're after a specific performance or fuel-type change. We're happy to compare both options for your situation.
