Dual-clutch gearbox, new flat-six could in the the cards.
That may be due to change, however. Reportedly, the 991-generation 911 GT3 will offer Porsche's PDK dual-clutch transmission as an option when the car arrives in a couple years. The information comes from a Rennlist user named "rosenbergendo," a current 911 GT3 owner who claims he heard it straight from a higher-up at Porsche when they were both attending the Rolex 24 At Daytona race.
In addition, the source supposedly disclosed a few other tidbits about the next GT3: it'll use the 911's new direct-injection flat-six making around 480 horsepower; it'll be around 180-200 pounds lighter than the current model thanks to more extensive use of composite parts; the car will not use hybrid technology; and the engine has been moved forward slightly to give the new GT3 balance similar to a mid-engined car. Now, we're taking a couple of those disposable fast-food packets of salt with these rumors for now, but nothing rosenbergendo wrote stands out to us as particularly unlikely, uncharacteristic of Porsche or impossible. A lighter, more powerful GT3? Bring it on. Just be sure we can still have a stick shift. [via Rennlist, AutoGuide]

Update: An earlier version of this article said the new GT3 would use a 4.0 liter engine; however, it appears the 4.0 liter RSR motor is destined for the 997-model GT3 RS LE, not the 991-era GT3.
