Work continues apace on the forthcoming GT2 RS, which "should be ready by the end of the year", our source said.
Initially Porsche engineers were looking for a massive power gain, even compared with the 612bhp of the original 2010 GT2 RS, but a plan to realise 700bhp was sidelined when it became clear the engine would need a water injection system to keep internal temperatures under control.
Instead, engineers are believed to have settled on an output of around 650bhp, almost 90bhp more than the engine produces in the current 911 Turbo S. That would provide for a specific output of more than 170bhp per litre.
Another source confirmed that this would be the last outing for the engine, which is based on previous-generation technology, and that the next Turbo would be based on the new flat sixes seen in the current 911 Carrera, S and GTS, but with an enlarged capacity.

A mule for the hotly anticipated Porsche 911 GT2 RS has been spotted testing at the Nürburgring again, but this time the car has gained covers over its GT3 RS wheel arch vents.
The model, which looks set to become the most extreme production 911 yet, still appears to be wearing a mixture of other GT3 and GT3 RS bodywork, while benefiting from a larger rear wing and race-style winglets on the front bumper.
But since it was last sighted in June, the mule's wheel arches have received extensive modification. The changes to the latest mule can be seen in the pictures above and immediately below, and the original mule is shown in the bottom image.
Although these modifications might only be used as part of testing, they suggest the GT2 RS could do away with the GT3 RS's vents and adopt a completely different aerodynamic design.
One thing that hasn't changed since the last sighting is the fitment of a pair of enlarged rear intakes. These have convinced our sources that the car is running the most powerful flat six engine to make production in a Porsche.
Porsche's latest limited-run 911 models, including the 911 R, have been based on the first generation of the 991-series of the 911. But the earlier sighting of this mule showed it was running second-generation rear lights, which backs up comments made last year by Porsche's high performance boss, Andreas Preuninger, that the GT2 RS would be based on the second-generation 991 and arrive at the end of the 911's production life.
