Modern upgrades for your Discovery

Keep the character of your Land Rover Discovery and improve the systems you use every day. Explore Rover V8 engine management and practical cabin upgrades developed by Regal Rover Classics.

Discovery 1 Rover V8 EFI

Replace ageing engine management with our Discovery 1 & Range Rover Classic Haltech Nexus R3 EFI kit. Vehicle-specific harness preparation, modern fuel and ignition control, and optional air-conditioning and charcoal-canister purge integration help build a properly planned conversion.

Made to order: estimated 3–10 weeks. Installation labour and final tuning are additional. We strongly recommend installation by a Haltech specialist; a full tune by a Haltech specialist on your local fuel and exact engine setup is required. The supplied base map is for setup and startup only.

Discovery 2 4.0 & 4.6 EFI — available to order

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.
