A rather unusual Porsche hotrod that is bound to leave fans of the brand shaking their heads has been listed up for sale in the UK.

The car has come to life thanks to custom builder Alexandre Danton and started out as a 1971 Porsche 911T, although very little of that original car remains.

Gone is the rear-mounted flat-six of the 911T; instead, the hotrod is powered by a turbocharged, front-mounted 6.75-liter V8 pumping out over 300 hp that was sourced from a Bentley Mulsanne Turbo. Coupled to this engine is an automatic transmission driving the rear wheels through a live axle. Like any good hot rod, the engine is completely exposed to the elements and one of the headlights has been replaced with a cold air intake to feed the V8.

Unsurprisingly, the car isn’t street legal but Danton did go to the trouble of equipping it with coilovers that allow the ride height to be adjusted.

There’s very little going on in the cabin. In fact, all the car features are a set of thin alloy seats, a flat-bottomed Sparco steering wheel, simple switches and gauges, and a prominent shifter.

Bonhams, who is auctioning the car off, expects it to sell for between £5,000 ($6,965) and £10,000 ($13,930).
