Land Rover owners can transform their vehicle into a truly wild V8 Defender by bringing in their existing vehicle for conversion or letting us find the perfect Defender and installing the LS V8 for them. Our years of experience in tuning has yielded the highest-ever performance levels from a Defender. Our technical abilities along with attention to each and every detail, has seen us develop cutting-edge components that are technically innovative and ultimately faster and stronger than the competition. The Nene Overland Wild Defender programme replaces the stock diesel engine and gearbox, with a GM derived 6.2L petrol V8 and 6 speed automatic gearbox providing 430bhp and more than 540 NM of Torque at 4,700 RPM. Additional power upgrades are available for power increases, providing over 550bhp.

Thanks to our longstanding experience installing all manner of diesel and petrol engines since the late 1980s, and our ability to understand and overcome some of the immense electrical and engineering challenges, we are confident that the inventory of parts – unique to Nene Overland – will enable remote specialist installers to carry out fitment worldwide without the need for any chassis welding or fabrication of one off brackets.

You will retain existing Land Rover Defender front and rear prop shafts, allowing the engine to fit at a far more natural, shallow angle rather than the excessive pitch of the engine offered by some other companies, which results in exaggerated stress to front prop shaft and unacceptable vibration at higher road speeds.

Nene Overland’s own unique heavy duty engine mounts simply bolt into place and are of a design that will give long life in the field to withstand the huge stress, power and torque produced by the 6.2 V8 LS and extreme potential engine shift from high speed cornering, braking and off road clatter.

A stainless steel exhaust system has been developed in-house at Nene Overland, again to enable simple fitment and long term reliability providing great performance with some V8 attitude without unacceptable droning while on long motorway drives. Further, bespoke twin pipe, quad pipe or side exit exhausts can also be offered to special order.

We have developed a correct, full width, deep core, alloy cooling radiator with full size, twin electric cooling fans and alloy ducting that has top and bottom inlet and outlets in the correct place to allow coolant to flow through the whole radiator core. This provides maximum cooling while in heavy city traffic or out in extreme hot climates whilst pushing the vehicle hard, off or on road.

We have spent many months developing a totally unique Dash-Driver ECU which is simply plugged into the vehicle, eliminating the need to spend a huge amount of time trying – and failing – to hardwire all the Defender dashboard functions.

The Driver ECU ensures that all the original Defender dash warning lights work and, most importantly, the temperature gauge actually reads correctly rather than only ever showing ‘normal’. The Land Rover factory-fitted alarm and immobiliser also works as intended. This might all sound straightforward, but if you speak to other installers other than Nene Overland, please ask them if they can match this functionality and note their vague response.

A bespoke wiring harness will also be provided as part of the kit that is made to exactly fit your Defender, automatic gearbox and engine installation in a tidy, OEM standard way. This ensures that should you ever need to investigate electrical issues with your vehicle in years to come you will not be stumped by the jumble of wires that we’ve seen on some other vehicles built by so-called ‘specialists’.
