What comes with your EFI kit
A complete engine-management hardware package for your agreed Rover V8 configuration. The kit brings the electronics, engine hardware, sensors and prepared wiring together, including the matching mounts, connectors, adapters and fittings for the supplied components.
Haltech Nexus R3 & prepared engine harness: a terminated loom and ECU configuration prepared by Alan Butler.
Modern fuel injection: Bosch injectors, matching connectors and injector adapters.
Intake installation components: air-temperature sensor intake section and the relevant breather fittings and adapters.
Installation support: documentation, pin-outs and fitment support for your chosen Haltech specialist.
Cable throttle configuration
Includes throttle-position sensing, idle-air control and the relevant plenum fittings for the cable-throttle arrangement. Your existing compatible cable-throttle intake is retained; this configuration does not include the DBW plenum, electronic throttle or pedal package.
Drive-by-wire configuration
Includes a modified, powder-coated Rover V8 intake plenum, electronic throttle body, electronic accelerator pedal and mounting hardware, together with the required connections. The supplied plenum is prepared from a used core. Intake and pedal mounting suitability are confirmed for your vehicle before assembly. Cruise control requires suitable controls, inputs and specialist configuration.
Optional vehicle integration
Air-conditioning integration and charcoal-canister purge control add the relevant harness connections and ECU configuration. Select these separately above. They do not supply an air-conditioning system, charcoal canister, purge valve or hoses.
What your installer still needs to do: fit and check the system, complete the vehicle-side wiring and fully tune your exact engine on your local fuel. Installation labour and final tuning are additional. Fuel-system upgrades and other work outside the agreed kit configuration may also be required.
What’s involved in fitting it?Tap to expand installation guideTap to close installation guide⌄
A prepared engine harness, matched components and installation guidance. The engine harness arrives with its component connectors fitted. The overview below shows the main stages for a typical 14CUX-equipped Classic; it does not replace the supplied installation guide, crank-trigger guide or customer pinout book. Vehicle condition, previous modifications and your selected configuration affect the work required.
1. Remove the old system and fit the new components
Start by removing the factory engine-management loom from the engine bay back to the ECU. Remove the redundant factory sensors, distributor and ignition coil components, then fit the new injectors, sensors, coils, cam-sync hardware and crank-trigger assembly. Complete the trigger alignment and clearance checks. If selected, fit the drive-by-wire plenum, throttle and pedal package. Fit the wideband oxygen sensor into a suitable exhaust bung; an exhaust technician may need to fit one.
2. Route the harness and plug it in
Lay the new harness over the engine and plug in the labelled component connections. Pass it through the factory firewall opening and run it back to the ECU, mounted in the factory location or another dry, protected location clear of interference. Secure the loom clear of heat and moving parts, then refit and seal the original harness grommet as instructed; replace it if unsuitable.
3. Complete the vehicle connections
Complete the switched-ignition and fuel-pump connections, plus A/C request/control and purge where selected. Route the main battery cables, trim them to suit and crimp the battery-end terminals. The main fuse and fuse holder, and any grommet or bulkhead fitting needed for a new power-cable penetration, must be supplied by the installer. Retained circuits must be identified and tested against your pinout book. Fuel-system work may also be required for your application.
4. Check, configure and tune
The installer or owner is responsible for checking the mechanical installation, wiring, connections and fuel system for leaks. An experienced Haltech specialist must complete the ECU setup before the first start attempt, including sensor and output configuration, trigger synchronisation and setting and verifying base ignition timing with a timing light. Oil pressure must be confirmed before the first start. A full tune for your exact engine and local fuel is required before driving. Installation labour, ECU setup, final tuning and additional vehicle-specific work are not included in the kit price.
Much of the component selection and harness preparation is already done. Owners can complete the mechanical installation and wiring by following the supplied guides and pinout book. We strongly recommend having a workshop carry out the installation, or inspect your completed work before ECU setup and the first start. ECU configuration and tuning must be completed by an experienced Haltech specialist familiar with Nexus R3 and NSP.
Modern EFI for Range Rover Classic & Discovery 1.
Made to order | Estimated lead time: 3–10 weeks
Required: full tuning by a Haltech specialist.
The supplied base configuration requires specialist setup and verification before the first start attempt. It is not a finished tune or a drive-ready calibration. Your vehicle must receive a full tune from a Haltech specialist in your country, using your local fuel and exact engine setup. Owners can install the kit by following the supplied guides. We strongly recommend workshop installation, or a workshop inspection of owner-completed work before ECU setup and the first start. ECU setup and tuning require an experienced Haltech specialist familiar with Nexus R3 and NSP. Arrange installation and tuning before ordering.
Keep the character of your Range Rover Classic or Discovery 1’s Rover V8 with modern Haltech fuel and ignition control. Developed through our own Classic build, this kit replaces ageing engine management with a system configured for your engine and vehicle.
We have installed our systems in early and late Classics, in both left-hand and right-hand drive. Tell us your year, engine capacity and intake setup so we can match the configuration to your build.
The Difference
Ageing fuel and ignition components can make a great engine frustrating to live with. Modern control allows precise management of fuelling and ignition, with tuning to improve cold starting, idle stability, throttle response and everyday drivability.
Whether your car is a weekend classic, a touring vehicle or a restored sports car, the aim is simple: make your Rover V8 easier to start, smoother to drive and more enjoyable to use.
Installed Across the Rover V8 Community
Our EFI systems have been installed in:
Early and late Range Rover Classics, in both left-hand-drive and right-hand-drive configurations.
A fully restored 1986 Morgan Plus 8.
A TVR Wedge 390.
These installations build on the same approach: modern engine management configured around the Rover V8 and the vehicle it lives in.
John’s Morgan Plus 8
John Turnbull · 1986 Morgan Plus 8 · 4.6-litre Rover V8
“Overall, driveability is so improved that I just want to keep driving it.”
John wanted easy starting, a consistent idle, clean running and a broad torque band from his Morgan’s Rover V8. He fitted our Haltech Nexus R3 EFI package, with the harness prepared to work with his chosen electronic throttle body and accelerator pedal, then had the engine professionally tuned at Madoc Performance.
In his written account, John reports that the starting and idling problems became a thing of the past and that engine responsiveness was elevated to another level. He also describes the wiring lengths to the engine sensors as very accurate and the installation as reasonably straightforward.
These are John’s results from his individual installation and specialist tune. Every engine and installation requires its own setup and tuning.
Excerpt from John’s customer article, supplied ahead of its planned publication in the global Morgan magazine. Photos used with his permission.
On our recent trip to Brisbane, our EFI-equipped Range Rover Classic with an 8-speed automatic was showing fuel consumption around 9–11 L/100 km while cruising at 110 km/h.
This is our observed highway cruising result with the combined EFI and 8-speed setup, rather than a tank-to-tank fuel economy test. Consumption varies with engine specification, tuning, gearing, tyres, load and driving conditions.
Harness & ECU Preparation by Alan Butler
Alan Butler, known as Turbo Yoda from Mighty Car Mods and The Skid Factory, prepares the kit’s wiring harness and ECU configuration.
That specialist preparation is paired with Regal Rover Classics’ Rover V8 development, vehicle-specific components and fitment support. It gives your installer a prepared foundation for the conversion.
The base configuration is a starting point for specialist setup. Your local Haltech specialist must complete commissioning before the first start attempt and fully tune your exact vehicle on your local fuel before driving.
A Complete Engine Management System
The Stage 3 system is built around the Haltech Nexus R3, bringing engine management and integrated power distribution together. Modern injectors, individual ignition coils, crank and cam timing inputs and a terminated engine loom form the foundation of the conversion.
Integrated power control and circuit protection simplify the engine management installation and reduce reliance on external fuse boxes and mechanical relays for the circuits managed by the system.
Kit configuration is matched to your engine and installation. Intake arrangement, throttle type, component mounting and vehicle-side connections are confirmed for your application.
Range Rover Classic & Discovery 1 Compatibility
For early and late Rover V8-powered Range Rover Classics, including hard and soft dash vehicles in LHD and RHD, and Rover V8-powered Land Rover Discovery 1 vehicles. We can assist with original, rebuilt and modified engines; intake layout, throttle type and vehicle-side wiring are confirmed for each installation.
Explore our Discovery 2 Haltech Nexus R3 EFI kit, with the same kit configuration and air-conditioning/purge choices as our established EFI packages.
We know the conversion can be done, but we have not yet built one ourselves. The Discovery 2 trigger setup requires additional development, testing and validation. Allow an extended timeframe beyond our established kits’ usual production estimate, and contact us before ordering to agree your configuration and timeline.
Cable Throttle or Drive-By-Wire
We can assist with cable-throttle and electronic throttle configurations. The optional drive-by-wire (DBW) upgrade adds electronic throttle control and allows features such as cruise control when the required inputs, controls and calibration are fitted and configured.
We will help establish the appropriate configuration for your vehicle, its intake setup and how you intend to use it.
Optional Vehicle Integration
These options add wiring, connections and ECU configuration to work with compatible equipment already fitted to your vehicle.
Air Conditioning Integration (+A$200)
Choose this if you want the Haltech ECU to work with your existing air conditioning. The ECU recognises when air conditioning is requested and can compensate for the compressor load to help maintain a steady idle.
Includes additional harness wiring, Deutsch connections and ECU configuration for compatible air conditioning request and compressor control circuits. Your existing air conditioning hardware and safety controls must be retained and checked by your installer.
Charcoal Canister Purge Control (+A$150)
The charcoal canister captures fuel vapour from your petrol tank. An electrically controlled purge valve allows that vapour to be drawn into the engine and burnt at suitable operating conditions.
Choose this to retain ECU control of a compatible existing purge valve. Includes the additional harness wiring, connection and ECU configuration. The charcoal canister, purge valve and hoses are not supplied with this option.
Vehicle integration options: Standard (no additional integration), Air conditioning integration (+A$200), Charcoal canister purge control (+A$150), or Air conditioning + purge control (+A$350).
Unsure which option you need? Email photos of your current setup before ordering. We confirm the requirements before harness assembly. Additional spare circuits for planned upgrades can be quoted separately.
Installation and Tuning: Read Before Ordering
A full vehicle-specific tune by a Haltech specialist is required. The supplied ECU configuration is a starting point only. The installer or owner is responsible for mechanical, wiring and fuel-leak checks. An experienced Haltech specialist must complete ECU setup, trigger synchronisation and base-timing setup and verification before the first start attempt. Oil pressure must also be confirmed before the first start. A full tune is required before driving.
Your chosen Haltech specialist must fully tune the vehicle for your exact engine specification, modifications, injectors, intake, throttle arrangement and the local fuel you will use in your country. The supplied base map does not replace this work. Do not drive the vehicle on the base map; arrange with your specialist how it will be transported for tuning.
You can install the kit by following the supplied guides and customer pinout book. We strongly recommend having a workshop complete the installation, or inspect owner-completed work before ECU setup and the first start. The ECU configuration and tuning must be handled by an experienced Haltech specialist familiar with Nexus R3 and NSP (Nexus Software Programmer).
Mechanical installation and wiring are separate from ECU configuration and tuning. Your installer or owner completes the installation checks; your Haltech specialist configures and verifies the ECU, trigger synchronisation and base timing before the first start, then completes the full tune before driving.
Installation labour and the required full tune are not included in the kit price. Arrange these services and their costs with your chosen Haltech specialist before ordering. Documentation, pin-outs and software references are provided to support the installation.
Vehicle-side wiring and application-specific fitting are required. Your fuel system must provide the pressure and flow required for EFI; carburettor installations and modified engines may require additional fuel system work.
Before ordering, email us with your vehicle make, model and year, engine capacity, left-hand or right-hand drive configuration, current intake and throttle arrangement, relevant modifications and engine bay photos.
Lead Time
Each kit is made to order. Estimated lead time is 3–10 weeks, depending on component availability from Haltech and Al’s availability to finalise the wiring harness and ECU configuration. Al, also known as Turbo Yoda from Mighty Car Mods and The Skid Factory, prepares these elements of the kit.
Complete the Build
Add a Haltech digital dash. Bring engine data, warnings and configurable displays together through the Nexus R3’s CAN connection. We offer a Range Rover Classic digital dash package for hard and soft dash vehicles. For Morgan, TVR and other Rover V8 builds, contact us about a suitable Haltech display and mounting requirements.

8-speed development. We are developing and validating our Rover V8 8-speed solutions in our own test vehicle before release. This includes work around Land Rover ZF 8HP70 installations and LT230 transfer case adapters. We also welcome enquiries about future rear-wheel-drive Rover V8 applications.
These transmission products are not yet available to order. Email us with your vehicle and gearbox details to discuss your plans and register your interest.
8-speed development in our Range Rover Classic test vehicle. Transmission products are undergoing testing before release and are separate from the EFI kit.
We assess your engine, intake, throttle, fuel system and vehicle wiring before harness assembly. We can assist with 3.5, 3.9, 4.0, 4.2 and 4.6-litre engines, modified builds and other capacities. Engine size alone does not confirm fitment. Send your vehicle details and engine-bay photos before ordering if requirements are unclear.
Is this only for Range Rover Classics?
No. Our systems have been installed in early and late Classics in LHD and RHD, a restored 1986 Morgan Plus 8 and a TVR Wedge 390. We also welcome enquiries for Rover V8-powered Discovery 1, Defender, Rover, MG V8 and custom applications. Each installation is assessed individually.
Can I install it and drive on the supplied map?
No. Specialist commissioning, including trigger and base-timing verification, is required before the first start attempt. A Haltech specialist in your country must then fully tune your exact vehicle on your local fuel before driving. Owners can install the kit using the supplied guides; workshop installation or inspection is strongly recommended before ECU setup and the first start. ECU setup and tuning require an experienced Haltech specialist familiar with Nexus R3 and NSP.
What should I budget for beyond the kit?
Installation labour and the required full tune are additional. Your application may also need fuel-system work, mounting or vehicle-side wiring. Ask your Haltech specialist to assess these costs before ordering. Supplied parts are those agreed for your selected configuration.
Should I choose cable throttle or drive-by-wire?
We can assist with either. Drive-by-wire can support cruise control when the required controls, inputs and calibration are fitted. Tell us your intake layout and whether you want cruise control so we can confirm the configuration.
What do the A/C and purge options do?
A/C integration lets the ECU recognise air-conditioning demand and compensate for compressor load at idle, with compatible request/control wiring. Purge control operates a compatible existing valve so fuel vapour captured by the charcoal canister can be burnt in the engine. A/C is +A$200, purge is +A$150, or both are +A$350. These do not supply an A/C system, charcoal canister, purge valve or hoses.
Will it improve fuel economy?
Correct tuning can improve how an ageing system runs, but there is no guaranteed figure. Our EFI-equipped Classic with an 8-speed showed approximately 9–11 L/100 km cruising at 110 km/h on a Brisbane trip. That was an observed highway result with both upgrades, not a tank-to-tank test or a result every vehicle will achieve.
Can I add a digital dash or 8-speed later?
A compatible digital display can connect through CAN. Our Range Rover Classic UC-10 dash is available separately; enquire about other vehicles. Our 8-speed products remain in development and testing and are not available to order. Tell us about future plans before your harness is built.
How long will my kit take?
Estimated production lead time is 3–10 weeks, depending on Haltech component availability and Alan’s availability to finalise the harness and ECU configuration. Freight is additional to production time.
Can you help customers outside Australia?
Yes. We support overseas Rover V8 enquiries and ship to supported destinations. Check your country and freight at checkout or email us. Arrange a local Haltech specialist and confirm local vehicle and emissions requirements before ordering.
Installation & tuning: A full tune by a Haltech specialist in your country, using your local fuel and exact engine setup, is required.
