No Surprise: Porsche 911 Turbo, GT2 and GT3 getting direct-injection
Click above for a high-res gallery of the 2008 Porsche 911 GT2.
Porsche's commitment to the KISS philosophy of exterior design won't extend to the engine of the facelifted 911 Turbo, GT2 and GT3 when they're released early next year. All three models will dispatch with the legendary M97 powerplant in favor of the new, direct-injected A91 flat-six that's equipped on the recently updated 911 Carrera.
The two turbocharged 911s will be packing 3.6-liters of displacement, with a 97 mm bore and an 81.5 mm stroke (the outgoing engine was sized 100 mm x 76.4 mm), along with revised turbochargers and intercoolers. Autocar's sources suggest that output on both models will rise by around 20 hp, with the Turbo producing 500 hp and the GT2 pushing out approximately 550 hp. Torque figures should also increase by around four percent.
The GT3 will remain naturally aspirated, with a 3.8-liter version of the A91 with a 102 mm bore and a 77.5 mm stroke. The same internal changes from the Carrera S will carry over to the GT3, including lightweight pistons, valves and springs. Output should increase from around 415 to 430 hp. And all of these changes will also increase fuel efficiency and decrease C02 output. 'Cause that's what really matters... right?

why not the LS2LS7? 2:29PM (7/30/2008)
Very nice.
I'm not really a Porsche guy, but they are seriously dedicated to advancing their engines.

Yeah, between the addition of DI and the introduction of PDK, I think these Porsche's are going to pack quite a whallop in the marketplace.
As if they needed it.

I agree with you guys. The addition of PDK and DI can only mean good things for Porsche.

I'd say they're generally pretty dedicated to advancing their cars as a whole. The fact that they are so involved in racing gets my loyalty, and this technology heads back to their road cars quicker than possibly any other manufacturer out there. Only quicker company I can think of is Ferrari, and they're in another league entirely in terms of price/exclusivity.

PDK is the one advance that will help taking the GT-R off their shoulders.

Yeah, I was holding off on getting a GT3 until the CO2 emissions got a little better. Looks like I'll be able to live with myself after going to pick one up now :).
430HP with 6 N/A cylinders... gotta love that.

No kidding. 113hp per liter of displacement is pretty darn amazing for a non-forced flat 6.
And forced induction pushing ~153hp per liter is pretty amazing, as well.
really makes me wonder what a Cayman with a DI GT3 engine would be like... holy smokes. That much lag-free horsepower, with the weight planted low and amidships, driving the rear wheels in a relatively modest weight little sports car with a hard roof and a stable chassis, and proper brakes...
What is not to be enthused about? Wow. Already amazing enough in rear-engined format.

mk, your Cayman GT3 just blew my mind.

glad to see them catch up with GM and Ford on the DI front.

I mean if this beats my ZR1 I will have to trade it in and get this. I need to make sure I have the fastest thing money can buy, and not even worry that the next genereation is bound to be faster, because I will just trade that in. I wont even have to pay anything because it will be a straight trade. I may even just trade in all of my cars and get my own car company, and then I will build the fastest car known to man, and then have that car, unless this porsche beats it, then I will just trade the company in and get a porsche.

somebody else comes to mind. "Farva"

I may be wrong but current Turbo, GT2, GT3 and GT3RS have the Porsche GT1 derived powerplant, not the M97. The latter powered the pre-DI Carrera, Carrera S, Targas and C4 cars.

The current Turbo, GT2 and GT3 do not use the M97 powerplant, and it is more infamous than legendary.
