The engine conversion kits come in four different flavors, offering power upgrades ranging from 600hp (450kW) in the ‘Stage 1’ kit to the full-blown 750hp in the ‘Stage 4’ range topper. For its most powerful upgrade, engineers reprogrammed the car’s ECU, added a pair of Sportec’s own turbochargers, new titanium connect-rods, sports camshafts, high flow exhaust kit, a sports air-filter and an upgraded clutch.
To further improve dynamics, the developers added a high-performance braking system with six-piston callipers and brake discs ranging from 350 to 380mm. A sports suspension kit is then fitted, including firmer springs and new shock absorbers. Visually, the Sportec 911 GT2 remains much the same as the original but features a new front spoiler and rear wing to aid downforce at high speeds plus 20in alloys.
