The 996 Turbo is powered by a water-cooled twin turbocharged/intercooled 3.6L H-6 derived from the 1998 LeMans winning GT-1 car.


The engine produces 415 hp (309kW) at 6,000 rpm and 415 lb·ft (563 N·m) of torque. It features all-wheel drive and was available with either a 6-speed manual or a 5-speed Tiptronic transmission.


It has revised styling and a wider stance than the naturally aspirated 996 Carreras, along with new bi-xenon headlamps. It also came with VarioCam Plus and stability management.

In 2002, the turbo offered an X50 option package that included larger turbochargers (K24 turbos) and intercoolers, a revised ECU and exhaust which raised output to 450 hp. 

At GCAP we have designed a package to further refine the German sports car's character with a few simple modifications.


We use a Quick Silver  exhaust system on our tuning packages for this vehicle.

QuickSilver can supply a 'Sport' exhaust system inc. Race Cats for your 911 GT2 (996). 

The result is a lighter weight system that has more efficient flow and shows a noticeable improvement in throttle response whilst enhancing that sports car sound.

The system is designed to work with the engine, so at lower revs the sound remains relatively civilised and at higher revs it provides more presence and volume.


We have developed our own software to increase the cars performance. This comes in two forms. A stage 1 map (I.E. a software only calibration with no hardware changes) and a stage 2 (with our Quick Silver exhaust system).

When tuning we measure afr, ignition timing, intake temps, EGTs etc. to ensure our tune is as safe and reliable as possible whilst drawing the most out of your supercar.


We have seen gains up to 550bhp and 540lbft.


As with most Porsche, the brake system is excellent. However we can offer modified braided brakes lines. Our lines have a stronger wall density delivering a more precise and accurate brake pedal feel. This translates into more confidence in your supercar.
