New engine? To lessen costs chances are it's going to be less stout than a racing engine. Will be okay during the warranty period. OTOH, in the years ahead, if a used Turbo didn't have a "bulletproof" GT1 engine my confidence in buying it might become be very low. As it stands now, as far as reliability, buying a used GT1 Turbo is a "safer" investment enginewise than a NA one.

Wait a minute, you guys don't have NOS in your TTs???? I thought that was a reliabilty mod. So I guess I have that 200 shot for nothing. Ahh well...

On a serious note, do all 07-09 TTs have the GT1 block then? Or just the 09?

If the 911 Turbo loses the GT1 block, then Porsche will exclusively be a poseur car manufacturer. Sorry but I will never buy that wet sump garbage.

all 997s have gt1, turbo that is

doc-

As in the GT1 supercar from the 90's? Is the 997 TT block related to that great supercar / race car engine? Or is it a designation from something else?

docjackson1

that i don't know-but i know that the recent turbos have been based on a more hearty engine than the regular normally aspirated 997-the concern on the new turbos is that the engine will change, and will be based on the regular 997. there is also a wet vs dry sump issue.

The current 99xTT, like the 99x GT2, 99xGT3, all share the same lump in the back.
The M64/GT1 derived lump. Same lump in the 993 and 964 as well. A true dry sump (not an "integrated dry sump" which is how PAG/PCNA describes the system in the NA 99x motors).

The last remaining link back to the 'proper 911' days. One of the greatest bits of engineering to be put into the Porsche roadcars.

Hey Pcar, where have you been?

I think he has been over on the Cayman Forum, literally over there. He started a poll thread titled: It really IS the Gayman...

That's good to hear. I hope Porsche doesn't take any signficant steps towards mainstreaming their road cars. To be quite honest, from 1997-2005, I was quite disappointed with Porsches in general. I was not a fan of the 996 until the later years of the C4S and later model Turbos. Then the 997 came out. When I first drove the 997 S, I called it the greatest car I've ever driven. Being fortunate enough to drive or own many different sports cars over the years, I thought the 997 S was a must have.

The biggest problem most car companies are having right now, imho, is that they are spreading themselves too thin. Porsche is walking that fine line right now. First there was the Cayenne. Now the Panamera, which is a sweet car that I will drive before making any real comment on. But I just realized the other day that there are about 17 911 models alone! This includes all 4, S, Convertible, Turbo, Targa and GT3 and GT2 variants. With all these different kinds of models and new ones on the way, I too sometimes worry that Porsche will cut some corners here or there. It's not in their nature to do so and every car company makes the occasional mistake, but with the economy so rough right now who knows? The 997, however, showed no signs of that threat as it truly is one special car.

The GT1 derived block is great. I don't car about that YouTube video supposedly showing the G forces associated with driving the Nurburgring using the new engine. It's the long term reliability, and ability to cope with high G's over time that makes the GT1 derived block a great engine.

Only time will tell how good the new engine/block is, and if the motorsports group adopts it.
The only thing for certain is that it has a hard act to follow.

I come around once in a while to stir the pot.

Did you get your 993 fixed?

pcar964

993 fixed, and now sold. Have a 930 now, finally!
