ROHMY HEMI 5.7 V8 + ZF 8-Speed Smart Automatic Conversion

For Defender 2.4 / 2.2 PUMA (2007–2016)

Introducing the most refined, most compatible, and most intelligent V8 conversion ever developed for the Defender platform. The ROHMY HEMI 5.7 V8 with ZF 8-Speed Smart Automatic Conversion transforms the 2.4 / 2.2 PUMA Defender into a modern high-performance machine—while preserving the Defender’s mechanical soul and off-road capability.

This system was engineered from the ground up to be fully plug-and-play, with zero cutting, zero welding, and no custom wiring required. Our proprietary wiring harness and ECU are designed to integrate directly with the vehicle’s original Land Rover harness, eliminating the need for any aftermarket electrical modification.

The result is a V8 conversion that behaves like a factory-installed powertrain—smooth, predictable, and exceptionally intelligent.

Factory-Level Integration

• Brand-new HEMI 5.7 V8 paired with a ZF 8-speed smart automatic gearbox

• Clean, intuitive shift logic following Land Rover’s OEM behaviour

• Fully compatible with the ROHMY Digital Cluster

 – Real-time gearbox temperature

 – Accurate gear position display (manual & automatic modes)

• Uses the Land Rover factory gear selector for a seamless cabin experience

• Low-range transfer case retained — full off-road capability is preserved

Perfect Parts Availability & Long-Term Serviceability

Every supporting component is carefully selected to ensure future maintenance is simple and reliable:

• 90% service-related accessories and secondary parts are available directly from GM, solving long-term parts sourcing issues

• No custom or one-off components that create future maintenance risk

Cooling & Intake Optimised for V8 Performance

• High-capacity full aluminium radiator designed for Australian climate and heavy-duty use

• ROHMY Dry Carbon Air Intake engineered for the HEMI — lighter, stronger, and allowing the engine to breathe more efficiently under all conditions

True Bolt-On Design

 

• All mounting points are engineered to factory alignment

• No welding required anywhere on the chassis or drivetrain

• Built to preserve the Defender’s structure while elevating performance

This is not just a V8 swap — it is the first smart, service-friendly, plug-and-play V8 ecosystem ever made for the PUMA Defender.

Powerful, smooth, reliable, and unmistakably ROHMY.
