900HP Supra 2JZ Powered Rolls-Royce Phantom

What happens when Rolls-Royce tell you that you’ll need to wait at least two years for a replacement motor for your Phantom? Well, if this Japanese owner is anything to go by, you throw the stock 6.75-litre V12 in the bin and replace it with a turbocharged & supercharged 2JZ engine.


The dignified growl of the Rolls-Royce V12 has been replaced by the ominous growl of the Supra derived 2JZ that suggests that this Rolls might be more at home drifting sideways on a skid pan than with two dignitaries in the back.

The 6.75-litre V12 found in the Phantom produces a healthy 338kW and 720Nm – enough to propel the 2.5-tonne land craft to 100km/h in less than 6-seconds and onto an electronically limited top speed of 250km/h. Impressive as these numbers may seem, they now seem rather insignificant compared to what the car is now capable of. The Rolls Royce 2JZ engine swap makes the popular Mazda RX8 JZ engine swap seem rather pedestrian.

The project was conceived and executed by J & K Power tuning who installed a 3.0 L 2JZ-GTE inline-six, strapped on a GReddy T78-33D turbocharger and a HKS GTS8555 supercharger and tuned the car to a conservative 1.6bar (23 psi) of boost. With its current tune, the 2JZ Phantom produces a monumental 445kW, with the owner insisting that it will be capable of 670kW once run in.

We’re not quite sure how to feel about this Phantom. The Rolls aficionado in us wants to condemn the owner to purgatory, but the drift enthusiast within us wants to see this monster going sideways around a wet track. Allegiances aside, I think we can all agree on one thing- it’s better than another LS-Swap.
