The facelifted version of the 997 Turbo was unveiled at the 2009 Frankfurt Motor Show. It received a completely new 6-cylinder, 3.8 litre boxer engine generating a maximum power output of and of torque ( of torque at overboost) with revised BorgWarner variable turbine geometry (VTG) turbochargers. The new engine used the same construction as other 997 Gen II DFI engines. The previous engine's Nikasil cylinder liners were replaced with an Alusil block that combined the cylinders and crankcase into an integrated casting for each bank, thus reducing weight (in contrast to a separate cylinder block and crankcase for each bank). The dry sump lubrication system in the Turbo is different from other 911 models in that it uses integrated oil reservoirs at the bottom of the engine, separate from the crank case and utilises six oil pumps due to the forced induction nature of the engine. The engine gets the direct fuel injection and a compression ratio of 9.8:1. The intake manifold is a slightly larger unit, adopted from the outgoing GT2 along with slightly larger intake valves, wheels for the Turbochargers and intercoolers. The exhaust system is also more refined and aids in the power increase while improving fuel economy. The overall result is an engine that is lighter than the previous engine and has a peak turbo-boost of 11.6 psi (a decrease from the outgoing model).
