The Porsche 911 Turbo TRC 91 created by Nardo God 9ff is powered by a modified 3.6-liter biturbo boxer' engine. Not only two special turbochargers increase the performance, but also the sport air filter, larger injctors, modified cylinder heads and a stainless steel exhaust system with special manifolds as well as high-performance catalysts, and, finally, an extensive increase in engine displacement resulting in 4.0 liters. All modifications are perfectly harmonized by means of the reprogrammed engine control unit.

Help by a modified racing front grill, the engine is provided with more air while the brake cooling has been improved by - discrete - additional air intakes. The body is made of carbon roof, so the car has a weight of just 2865 lbs.

Optimum performance is brought to perfection through revised aerodynamics enhancing the powerful Porsche's driving stability while creating an atmosphere of even more dynamic elegance. The monstrous inner workings, however, do not reveal themselves that easily to a layperson. The experts at 9ff confined themselves to a slightly lower front apron and elegant 20-inch wheels with a larger braking system.

The car also features: new and shapely front spoilers, side skirts and redesigned rear wings added to the aerodynamic kit while the elegant and aerodynamically enhanced exterior mirrors are the crowning glory of the whole.
