Guntherwerks can turn your 993-generation Porsche 911 into a 400R

Article by Christian A., on August 20, 2017

A lot of us know Singer Vehicle Design and their signature work of reimagining Porsche 911s, and making them look like hot rods from the 70s. They are not alone as a company called Guntherwerks has recently been applying the same style to Porsche’s iconic coupe from the 1990s - the 993 generation.

During the Monterey Car Week, Guntherwerks decided to showcase one of their works, the 400R at The Quail, a Motorsports event. They revealed that this unique model costs half a million, or $525,000 to be precise. And the company plans to build only 25 examples of this beginning this year, where they will deliver the models in 2018.

A standard 993 is equipped with a 3.6 liter flat six. But Guntherwerks will replace this with a naturally aspirated 4.0 liter engine instead paired with a six-speed manual, with an output of around 400 horsepower (298 kilowatts) and 330 pound-feet (447 Newton-metres) of torque. Whereas with the old engine, the 993 only produced 270 horsepower (201 kilowatts).

Of course, there are a lot of noticeable changes on the outside, starting with the new bodykit that has been made wider, evoking the broad shape of the 993-spec Porsche 911 GT2. The tuned version will now have carbon fiber bumpers, fenders, and roof. It will be given a set of 315/30 18-inch rear tires, thanks to the more muscular flares. These Pirelli P Zero Rosso tires will work hand in hand with a set of KW Clubsport coilovers too. To finish off the exterior design, Guntherwerks gives it a pair of LED headlights up front, and an adjustable wing at the rear.

A makeover will never be complete if the cabin has not been touched, so the tuner adds a bit of sportiness and luxury to it, by combining leather and Alcantara racing seats finished in black, with red stitching. The tachometer now gets a red backdrop to make it stand out from the instrument panel. The rear seats have now been replaced by a carbon-fiber panel, as well as a half roll cage that will be important for the driver’s safety for track use. The 400R will definitely have a comfortable interior with proper air conditioning and heating. The keys are now custom made by Belgian company Conid Pens.

Guntherwerks will have to get donors for the cars they will be customizing. However, if you are an owner of the 993-generation 911, and you want an upgrade to turn it into a 400R, the company will be more than willing to take your car in to give it some tweaks, just be ready to shell out a considerable amount of cash.

GUNTHERWERKS UNVEILS BESPOKE 400R CONCEPT AT THE QUAIL, A MOTORSPORTS GATHERING

Guntherwerks, a company dedicated to remastering the iconic
Porsche® 993, held the global reveal of its highly-anticipated concept, the 400R, at The Quail, A Motorsports
Gathering on August 18. The company will begin producing a limited run of the concept later this year.

Hand-built and re-engineered from the ground up for the most discerning clientele, the 400R is built on a
Porsche® 993 platform, which is considered by many to be the pinnacle of the 911®. The 400R incorporates
modern technology, while still maintaining the essential components of the original car that inspired so
many enthusiasts. The body has been widened extensively with the bumpers massaged to blend seamlessly
to produce a unique silhouette, while still remaining instantly recognizable as a 993.

Each 400R is equipped with a 4.0L naturally aspirated air-cooled engine, hand-built and meticulously tested
by Rothsport Racing to produce over 400hp and 330lb/ft. No stone has been left unturned with the 400R.
From its top-of-the-line coilovers, massive 315/30/18 rear tires and adjustable aerodynamic capabilities,
the 400R is truly a performance-built machine.

The 400R’s interior is customizable, but fastidiously upgraded with leather and Alcantara options, fixed
bucket seats that pay homage to the vintage 993 race cars, a carbon fiber rear seat delete, a half cage
behind the driver’s head and a classic 5-dial dashboard with a rev counter in the middle.

“Aesthetically and technologically, the 993 is considered by many multiple decade Porsche aficionados as
the last real Porsche,” said car collector and Porsche enthusiast, Peter Nam, CEO of Guntherwerks. “With
the 400R, we set out to build a car that incorporated modern technology while still appealing to the
enthusiasts who covet these cars today. In essence, the 400R is the car we imagine Porsche would have
built if the advanced technology within the 400R was available.”

Only 25 examples will be made, with first customer deliveries expected by early 2018. Customers can supply
their own road-legal 1994-1999 993 Series Porsche® 911® Coupe for the basis of the Guntherwerks 400R
conversion. Alternatively, Guntherwerks can source a suitable donor car that can be used as the basis of
their 400R remanufacture.
