Stage 1 — Core EFI Conversion

Modern Haltech EFI built for Rover V8s. Reliable cold starts, smoother idle, and no more distributor headaches. A clean replacement for 14CUX and carb setups with better drivability and fuel economy.

Haltech Elite 1500 ECU with unterminated loom (professionally terminated in-house)
Plug-and-play wiring harness for Rover V8
Bosch fuel injectors – 2025 tech, not outdated 4-hole units
Crank trigger kit: 36-1 wheel, custom bracket, Hall sensor
2× Discovery 2-style wasted-spark coils + mounts
Idle air control valve (Bosch style)
Coolant temp, IAT, oil pressure sensors
Haltech WB1 Wideband + Bosch LSU 4.9 O2
3D-printed MAF replacement adaptor (clean IAT mount)
Base map included + PDF wiring diagram

Stage 2 — Performance Pack

Everything in Stage 1, pushed further. Sequential fuel injection, full trigger sync, and a higher-end setup that unlocks torque, throttle response and fuelling precision.

Haltech Elite 1500 ECU with unterminated loom (professionally terminated in-house)
Sequential injector harness — full sequential delivery
Bosch EV6 injectors for cleaner atomisation
Crank & cam sync: 36-1 crank, cam sync pin, twin Hall sensors
2× Discovery 2-style coil packs + brackets
Idle air control valve for cold-start stability
MAP, IAT, coolant temp, oil pressure sensors
Haltech WB1 Wideband + Bosch LSU 4.9 O2
3D-printed MAF replacement adaptor
Refined base map for sequential + PDF wiring diagram

Why Stage 2? Sequential injection, crank+cam sync, future-ready (CAN, DBW, digital dash), stronger transitions under load.

Stage 3 — Complete Plug & Play System

This is not just “more parts”. It’s a finished system. Built around the Haltech Nexus R3 with an OEM-style labelled loom, pre-installed sensors, validated trigger setup, and a street/dyno-tested base map. It’s engineered to save major install time and remove wiring risk.

Why Stage 3 costs more — and what you get for it

Nexus R3 hardware jump: Integrated wideband, robust CAN hub, DBW-ready, advanced I/O — no add-on boxes.
Premium loom: Vehicle-style, labelled, plug-and-play routing with factory-look finish.
Pre-installed sensors & triggers: Twin-wheel crank/cam sync, MAP/IAT/CLT/oil/TPS all terminated and tested.
Bench-tested assembly: ECU + loom + key sensors validated together before it leaves our shop.
Proven calibration: Street tuned and 4WD dyno-validated base map.
Time saved: Typically 30–50 hours vs building a loom from scratch.
Risk removed: Less chance of wiring mistakes that kill ECUs or waste weekends.

Factory-style engine loom — routed & labelled for classic Range Rover bays
Haltech Nexus R3 ECU — CAN-ready, built-in wideband, DBW-ready, 8-speed compatible
Bosch modern injectors + plugs
LS coil packs + brackets
Crank & cam trigger kit — CNC bracket, twin sensors
Wideband O2 with plug-in loom
All key sensors pre-installed: MAP, IAT, CLT, oil pressure/temp, TPS, crank/cam sync
3D-printed routing aids for a clean install
Pre-mapped: Street tuned & 4WD dyno tested

Factory-style Loom — plug-and-play

Bosch Injectors — clean spray pattern

Crank & Cam sync — precise timing

LS Coils — reliable spark

Additional Notes

O2 sensor: Requires a bung in your exhaust. Clamp-on or weld-in kits are readily available.
Carburetted V8s: Works with non-EFI Rover V8s; you’ll need an EFI intake (e.g. from a 3.9L).
Tuning: A final tune is recommended for best results on your particular engine and mods.
