Toyota Supra Converted To Off-Road Monster With Diesel Cummins Engine Swap

This Supra is certainly going to be Marmite for you, and if you really love the JDM icon, you might not want to continue… This Supra has a Cummins engine and air suspension, and has been specially built for off-roading on the desert.

Ashley Whitsey is its owner, posting the specs of this rally-ready machine onto Facebook. It’s got large wheels, air suspension, and… not a 2JZ. The Toyota straight-six has been removed and replaced with a 12V Cummins straight-six turbodiesel engine. That’s the Marmite bit, if you didn’t realise.

According to the owner, it makes a modest 250hp, but with 620 lb-ft of torque, it can move. After a few modifications planned, including a new turbo, a manifold, a new intercooler, and bigger injectors, Ashley is hoping to kick the power up to 500hp and 1000 lb-ft of torque.

As you can tell from the video, this hasn’t been the easiest of engine swaps with plenty of other alterations made to make this a respectable off-roader. And on startup, it sounds like it should be pulling a trailer.

The tyres come in at 30″ at the front and 32″ at the rear, and squeezed in behind the seats sits the Air Lift universal suspension kit paired to a pair of Airmaxx 580 compressors. This means it can run extra height if it needs to, and drop back down to the road for tarmac duty.

A few other modifications including reducing the overhangs and extra lighting have been carried out, but we love the way it looks and would be against the thought of painting it. Maintain its ratty aesthetic because it’s going to look so good in action.

Alex started racing at a young age so certainly knows his way around a car and a track. He can just about put a sentence together too, which helps. He has a great interest in the latest models, but would throw all of his money at a rusty old French classic and a 300ZX. Contact: [email protected]
