Prior to 2012, engines of up to 2,000 cubic centimetres (120 cu in) were allowed, with only limited modifications from standard engines. This was both to reduce running costs, and give a level playing field to every team. Variable valve timing, variable intake geometry, anti-lock braking systems and traction control are all forbidden.
From the 2012 season, Radical Performance Engines will provide 2.7 litres (160 cu in) RPE TCX V8 engines (a front-wheel-drive variant of the RPX, originally found in the Radical SR8), capable of producing 430 brake horsepower (320 kW), in place of the previous 2 litres (120 cu in) engines. The series was renamed to Súper TC 2000. Meanwhile, cars with the old regulation continue competing as a second-tier championship with the name TC 2000, currently with an independent calendar.
