Porsche considering turbo for new GT3 RS [w/poll]

Some automakers make one hardcore version of a sports car and are done with it. Or at least they make one at a time. Think Ferrari 458 Speciale, Lamborghini Gallardo Superleggera (or Super Trofeo Stradale or Squadra Corse) or Maserati GranTurismo MC. But not Porsche. It transforms the 911 into the hard-core GT3, the even harder-core GT3 RS, the you've-got-to-be-psychotic GT2 and the do-you-have-a-death-wish GT2 RS. The RS models take things to a further extreme, but what separates GT3 from GT2 models has traditionally been the use of foced induction: GT3s are naturally aspirated, while GT2s go turbo. But that could all be about to change.
According to the rumors making their round of the webosphere, Porsche is considering using a turbocharged engine for the next GT3 RS. The reason is that, as we all know, Porsche has already pushed the 3.8-liter flat-six in the existing GT3 about as far as it can go, and then some. And buyers expect not only a more bare-bones package with the GT3 RS, but also a bit of extra power.
Given that everything seems to be going turbo these days, the move might make some measure of sense, especially if Porsche wants to avoid with the GT3 RS the spontaneous combustion issues it faced with the GT3. But we can't help but wonder why, at that point, it wouldn't just skip the GT3 RS and go straight for the GT2.

911 beware! Porsche testing new top-trim Boxster

The Boxster and Cayman are like the scrappy siblings compared to their star brother – the Porsche 911. And now it looks like the rivalry is about to get even more serious, as our spies have captured this hotted-up Boxster doing some winter testing. We've already seen Porsche evaluating a higher-performance version of the Cayman, rumored to be called the GT4. It would reportedly offer a taste of the thrills of the 911 GT3, but at a lower price. The coupe appears to have a convertible twin in this Boxster prototype. The biggest giveaway of their possible relationship is the shared front bumper with larger intakes and an extra opening at the tip of the hood. Although, this one lacks the Cayman's big, rear spoiler in favor of a smaller decklid unit. The good news for fans of shifting for themselves is that this tester is fitted with a manual transmission, according to our spies. Being a prototype, though, there's no guarantee that the gearbox makes it to production. At least in Cayman trim, these higher performance models might use a tuned version of the 3.4-liter flat-six with between 370 and 400 horsepower. Though, an earlier rumor suggested that a turbocharged four-cylinder could sit behind the driver. Until we know for sure, glance at the gallery to see a Porsche that might try to challenge its big brother.

Ruf Turbo Florio is the Turbo Targa Porsche won't sell you

Porsche offers a staggering array of 911 variants. You can get the Carrera, Carrera S, Carrera GTS, Carrera 4, Carrera 4S, Carrera 4 GTS and Turbo and Turbo S (to say nothing of the GT3 and new GT3 RS). And with few exceptions, you can get each as a coupe, cabrio or Targa. Except you can't get a Turbo Targa. The partial-convertible model tops out at the GTS. But if the one thing you really wanted was a Targa with a turbo engine, the folks over at Ruf will be glad to hook you up with the tuned version you see here. It's called the Ruf Turbo Florio, taking the latter part of its handle from the second part of the Sicilian road race where Porsche got the name for its lift-top in the first place. But Ruf's take doesn't just match the factory Turbo's output – it far exceeds it: with 621 horsepower and 608 pound-feet of torque on tap, it'll put even the 911 Turbo S (on Sport Plus overboost, no less) to shame. Plus you can get it with a six-speed manual or seven-speed DCT, driving all four wheels like the factory Turbo or just the rear set like the GT2 that Porsche doesn't even make any more. It'll top out at 205 miles per hour, and all the while with the wind in your hair – but not too much of it. Related Video:
