When Porsche’s regular offerings are not up to snuff with your discerning tastes, there are a couple of customization outfits we would gladly recommend. First is Los Angeles, California-based Singer Vehicle Design, followed by Pfaffenhausen, Germany-based Ruf. We’ve discussed several projects from the former, but it’s time we share something awesome from the latter. This is the Ruf 3.4 RSR.

If you want a masterpiece, never rush an artist’s work. We need to give them all the time they need to envision every detail and explore every nuance available. Meanwhile, anything from Ruf Automobile is as prestigious as the rarest Porsche examples out there. This is why the shop always has its hands full.

Buyers all over the world would willingly pay extra to reserve a slot in their books. This Ruf 3.4 RSR in Blau Metallic is over a decade in the making. Word is a client had the opportunity to join Alois Ruf Jr. for a drive in what might have been an unlisted one-off. It was love at first ride and an order was placed.

Transforming an E Series 911 donor to a magnificent bespoke beauty resembling a 1973 Carrera 2.8 RSR is no easy feat. Circle over to the rear and you’ll find a custom 3.4-liter inline-six with high-velocity stacks, new pistons, a reworked camshaft, and a digital fuel injection system.

Governing everything about the Ruf 3.4 RSR’s mill is a Bosch Motronic ECU. We’re now looking at an output of about 316 bhp and 254 lb-ft of torque which it delivers to the rear wheels via a five-speed Porsche G50 gearbox. It can manage a 0-62 mph run in 4.4 seconds with a top speed of 168 mph.
