The Gemballa GTR 8XX EvoR retains the 911 Turbo's 3.8-liter flat six but pushes the output to 807 horsepower (602 kilowatts) and 810 pound-feet (1,098 Newton-meters). This is quite an upgrade over the Turbo S' stock 572 hp (427 kW) and 516 lb-ft (700 Nm), and it even puts the GT2 RS' 690 hp (515 kW) and 553 lb-ft (750 Nm) to shame. The EVO-R can hit 0-62 mph in 2.38 seconds and go from 0-124 mph in only 7.5 seconds. It has a top speed of 230 mph.
