Independent tuner Indecent has unveiled a bold conversion of a Porsche 911 Carrera (991.1) into a Slantnose variant, producing 550 horsepower from a naturally aspirated 4.0L flat-six — no turbochargers. The build challenges Porsche's own attempts to revive the classic design.
In a clear challenge to Porsche, a small independent tuner named Indecent has revived the legendary Slantnose design for the 911 — on its own terms. The conversion transforms a Porsche 911 Carrera (991.1) into a 550-horsepower naturally aspirated monster, beating Porsche’s official efforts to bring back the iconic 1980s look.
What is the Slantnose design?
The Slantnose (or Flachbau) is a modified version of the Porsche 911 that debuted in the 1980s. It features pop-up headlights instead of the traditional round units, giving the car a sleeker, more aggressive profile. Porsche produced only a limited number of official Slantnose models back then and has not offered a modern factory version.
How did the tuner achieve 550 HP without a turbo?
Indecent developed a 4.0-liter flat-six engine internally, with upgrades to the intake and exhaust systems, modified cylinder heads, and an optimized fuel injection system. The result is 550 horsepower at 8,500 rpm and 460 Nm of torque, all sent to the rear wheels through a 6-speed manual gearbox.
Did this car beat Porsche’s official attempts?
Porsche itself has tried to revive the Slantnose spirit through special editions like the 911 Speedster and 911 GT3 Touring, but none feature pop-up headlights. This conversion surpasses those efforts in both power and boldness, offering performance that exceeds the 911 GT3 RS while retaining the classic design.
Key exterior modifications
- Retractable pop-up LED headlights
- New front bumper with larger air intakes
- Wider 19-inch rear wheels
- Fixed rear wing inspired by the 911 RSR race car
- Two-tone paint (white with blue stripes)
How much does the conversion cost and is it available in the Gulf?
The tuner has not announced an official price, but estimates suggest the conversion starts at $150,000 (approximately SAR 562,500) plus the cost of the base car. Currently, the conversion is only available in the United States, but Indecent is studying expansion to other markets, including the Middle East.
When will this car reach Saudi Arabia or the UAE?
No specific date is set. If the tuner expands, the UAE is likely to see it first due to its strong modified-car market. In Saudi Arabia, it may take longer due to licensing and approval processes. However, with growing demand for classic modified cars, it could appear at shows in Riyadh or Dubai within two years.
