Rover V8 EFI Conversion Systems

The Regal Rover Classics EFI range modernises the Rover V8 with reliable cold starts, smooth idle and the flexibility of Haltech management. Choose from three build stages — from entry-level EFI conversion to our fully engineered Stage 3 Plug & Play System that arrives bench-tested and ready to run.

Build time: Each system is built to order. Standard lead times are 3–6 weeks depending on stage and component availability.

Customer Must Supply

3.5 L engines: Must be upgraded with a 3.9 L Rover V8 plenum and intake manifold — the 3.5 L version does not have injector bosses. Customer to supply.
O₂ sensor bung: Your exhaust must include a weld-in or clamp-on bung for the wideband sensor.
