Autocar has learned that Porsche will fit the forthcoming facelifted versions of the 911 Turbo, 911 GT2 and 911 GT3 with its new-generation of direct injection petrol engines. It’s part of Stuttgart’s plan to improve the performance of its harder-edged 911s, while also making them more economical and reducing their CO2 emissions.

In a move that spells an end to the company’s legendary horizontally opposed six-cylinder M97 powerplant – the so-called Metzger engine - all three models will adopt the new A91 direct injection engine. This was first unveiled in the facelifted 911 Carrera that has just gone on sale in the UK.
Both the 911 Turbo and 911 GT2 are will get the new 3.6-litre version of the horizontally-opposed, six-cylinder A91, with a 97.0mm bore and 81.5mm stroke (compared with the old engine’s 100mm x 76.4mm). This ultra-modern direct injection unit also gets twin turbochargers and intercoolers.
Official power figures are yet to be revealed, but Autocar sources suggest a 20bhp increase over the old cars, taking the four-wheel drive 911 Turbo up to 500bhp and the rear-wheel drive 911 GT2 to around 550bhp.

The updated rear-wheel drive 911 GT3 will get a naturally-aspirated 3.8-litre version of the A91 engine with 102mm bore and 77.5mm stroke. It will receive a number of internal revisions over the engine used in the 911 Carrera S, including lightweight pistons. This should push power from today's 415bhp to nearer 430bhp.

As well as increasing performance, the decision to offer the 911 Turbo, 911 GT2 and 911 GT3 with direct injection engines further streamlines production at Porsche’s Zuffenhausen engine plant. At the moment, the old Metzger engine is built on a separate line to the A91.

 

Interesting. This will be good.

 

The end of an era boys.

 

2009 models? As in coming later this year? Giving a power boost before the 998 (or whatever they're going to call it) sure is a good way to **** off current 997 owners and destroy their resale value

 

Sorry, not sure if this is for 2009 - maybe not.

 

Sad to hear especially since those motors are garbage.It May be the end of big power Porsches.I wonder if they will give you a garage matt free with the car to catch oil from the leaky RMS'S.

 

They can jack up the power all they want, it's still a pos wet sump motor. If true for '09, the values of the '07-'08 should go up as they are truly the last of a breed.

 

NOT!!!!

 

This is for 2009 models guys

 

Just like the 997 did to the 996

 

2009 Carrera gets new block.

2009 TT gets the GT1 block.

2010 TT gets the new block.

And it all makes me puke. I'd love to get into a new TT, but a) it does bother me they are moving from GT1 to something lesser for '10 and b) the car just does not have enough 'wow' factor to warrant moving from my pristine C4S Cab that I really enjoy. If it did, I'd line up now. I can build an '09 TT Cab if I want, but at 160-170 large, at least give me WOW factor. Oh yeah, and PAG, how about a decent steering wheel too?

So far, eh.

 

Yeah, but we're not talking the successor; it's still the 997.

 

So my sept build tt is a gt1 block??

 

This only helps current 997tt values, just like the 993-996 effect.
Yeah, you can have a pdk, but it comes mated to a line engine.

 

This is Porsche we are talking about here. They arent going to put out junk. And if the motors proove durable, which I'd bet money they will (at some point) the current non DI engines will be obsolete, but if you mod, you'll just have to build more of the motor at high power levels.
