Rover V8 EFI Kit – Complete Plug & Play Solution

Modern EFI performance for classic Range Rover and Discovery V8s – Haltech-powered, CAN-ready, and street-tuned in Australia.

This is a complete plug-and-play Rover V8 EFI conversion kit, engineered for Range Rover Classic, Discovery, and other vehicles running the 3.5L, 3.9L, 4.0L or 4.6L Rover V8. Built around the cutting-edge Haltech Nexus R3, this system replaces outdated 14CUX or carburetted setups with modern fuel injection, better drivability, proper diagnostics, and full CAN integration for 8-speed autos and digital dashes. Pre-mapped and dyno-tested, it’s a complete solution – no tuning or wiring guesswork required.
