An Australian-built Porsche 911 has abandoned the model’s signature rear-mounted flat-six for a front-mounted, twin-turbocharged V8 producing more than 1,200 horsepower. Known as the ShowTime Repco 933, the heavily modified car began life as a 996-generation 911 before being transformed by car builder Gary Reid.

The centerpiece of the conversion is a 7.0-liter GM LSX V8, replacing the original 996 engine with a powerplant more than twice its displacement. Reid’s team added a pair of large Turbosmart turbochargers, with exhaust outlets that direct flames through the hood.

Extensive chassis and transmission modifications

Installing the substantially larger engine required a new firewall, floor, and transmission tunnel. Even after those changes, the V8 extended several inches beyond the engine bay, leading to the installation of a heavily modified hood with a large opening.

The original Porsche transmission was not considered suitable for the engine’s output. In its place, the 933 uses an eight-speed Bentley transmission modified with sequential-shifting functionality. All of the engine’s power is sent to the rear wheels.

With more than 1,200 hp, the 933 exceeds the output of any regular 911 and is rated more than 200 hp above the Porsche 918 Spyder’s 4.6-liter plug-in hybrid powertrain.

Built for straight-line speed and drifting

The modifications extend beyond the powertrain. A heavy-duty cooling system has been fitted inside the passenger compartment, while the cabin receives a custom dashboard, a new infotainment display, and an aftermarket digital instrument cluster.

A multifunction Haltech steering wheel provides buttons and toggles for drive-mode changes and on-the-fly adjustments. Carbon-fiber Recaro seats add to the revised interior, which also includes a bespoke transmission tunnel containing a carbon-fiber sequential shifter and a hydraulic rear handbrake.

Those components reflect the car’s intended use beyond acceleration. The 933 was also built with drifting in mind, combining its rear-wheel-drive layout with controls designed to help manage the car during sideways driving.

Hand-built exterior and custom wheels

Reid’s team created a bespoke body kit featuring flared wheel arches, a carbon-fiber hood, and a large rear wing. The rear decklid also incorporates a shark fin influenced by Le Mans Prototype race cars.

Custom Rotiform wheels complete the build, measuring 18×9.5 inches at the front and 18×10 inches at the rear. The result is a 996-based 911 that retains its rear-wheel-drive layout while replacing Porsche’s traditional flat-six configuration with a front-mounted, twin-turbocharged V8.
