Someone Crammed a Viper V10 Under the Hood of a BMW Z4

It’s not cheap, but is cheaper than any current M model

In the universe of coaching (or any other area that involves engine-swapping), the “standard” unit is GM’s 6.2-liter V8 LS. Accessible, user-friendly, massive yet small enough to fit under an M2’s bonnet.

Then are those cases where the focus is shifted towards Chrysler’s 8.3-liter V10, like this one right here. A BMW Z4 Coupe died and was respawned into this world with a gigantic heart collected from a Dodge Viper.

It wasn’t easy to dope a small BMW Z4 with an 8.3-liter engine drive – the exhaust pipes coming from the engine and through the engine bay weren’t a walk in the park to install, as you can easily figure.

The result is a brutal BMW Z4, packing some 540+ horsepower (550 PS) and 553.17 pounds-foot of torque (that’s 750 Nm) of which 90% are available at 1,500 rpm because there’s no replacement for displacement.

But wait, there’s more! Its creators mentioned that through a force-feeding process, the same engine can deliver 700 hp and 663 lb-ft of torque (900 Nm). We’d say that’s more than enough for a 3,000-pound (1,400 kg) car, right.

It looks fierce, but mind you, it’s not just a pumped-up small coupe. Everything was made with safety in mind, also: it features an FIA-certified cage, Audi R8’s 6-piston Brembo brakes, 6-point harnesses.

It’s road legal. It’s €49,500 ($55,600). It is a one-off. Is it a deal?
