One of the most proficient Porsche models on the racetrack is the 911 GT3. It is designed specifically after the GT3 RSR race cars that Porsche uses in motorsports worldwide and is built to handle fast corners with ease. But the downfall of the 911 GT3 was that it wasn’t exactly a straight-line performance car, until the German car tuning specialists at 9ff transformed it with the GTrubo 1200. The new upgrade program gives the naturally-aspirated engine a powerful twin-turbocharger upgrade to go along with a modified chassis, new Porsche wheels, and a special exhaust.
The standard engine that comes in the 911 GT3 is a naturally-aspirated 3.8-liter that was designed after the racing engines used in the 911 GT3 RSRs sold by the German automaker. The high-revving flat-six cylinder engines were given a complete makeover thanks to 9ff with a new twin-turbocharger system that drastically increases output. The engine was bored out to 3.9 liters of displacement, reinforced with new steel pistons and rods, given upgraded camshafts and a new crankshaft, and fed with a new carbon fiber air box that fits onto a refinished intake manifold. A new exhaust system with sport catalytic converters, downpipes, mufflers, and quad tips helps to reduce backpressure and ensure that the turbochargers spool up quicker. After an ECU tune, the engine sends 1,200 horsepower at 8,100 RPM and 848 lb-ft. of torque at 5,800 RPM to each of the rear custom Porsche wheels. This blistering power output allows for the 9ff GTurbo 1200 to reach 62 mph in just 3.3 seconds, 124 mph in 7.1 seconds, and a top speed of 250 mph.
The power increase also necessitated that the chassis be upgraded. The transmission, driveshafts, and differential were all replaced with stronger units to handle 1,200 horsepower. The standard Porsche wheels were removed and new forged rims were installed with a center-locking mechanism similar to those used in race cars. In addition, new carbon ceramic brakes used in more powerful Porsche models were retrofitted to the 9ff GTurbo and a special Bilstein suspension was installed to allow for variable height, bound, and rebound settings. The finishing touch is a set of Continental Vmax tires fitted to the Porsche wheels that can handle the 200+ mph top speeds.
The cockpit of the new 9ff GTurbo 1200 features a more sport-oriented atmosphere. The two front seats were removed and replaced with special bucket seats that hold passengers in place better and are outfitted with alcantara. The dashboard, door panels, and center arm rest were each trimmed in a mix of leather and alcantara.
The new 9ff GTurbo upgrade conversion that includes the twin-turbocharged engine rebuild, new suspension, custom Porsche wheels, and unique interior design is currently available worldwide.
