"More than one year after the regular Porsche 911 migrated to Phase II of the 997 architecture, the Turbo follows. The most important change: A new twin-turbocharged, direct-injection flat-six engine with higher compression (9.8:1, from 9.0:1), a displacement of 3.8 liters (up from 3.6) and 20 more horsepower—the new 911 Turbo makes 500 hp at 6000 rpm, versus the previous model's 480 hp. Maximum torque for the new car is 479 lb-ft at 1950 rpm (516 lb-ft at 2100 rpm with the optional Sport Chrono package), while its predecessor delivered 460 lb-ft (505 lb-ft with Sport Chrono).
Porsche says the revisions improve the Turbo's already stellar performance, with the company claiming the run to 60 mph now takes 3.2 seconds"

2003 Turbo. Professionally modified by Prototech: larger Garrett double ball bearing turbos, ECU map, 5 bar fuel regulator & custom rear spoiler for forced air induction. F/R K40 radar, Tubi exhaust, sport shifter, champion rims, racing suspension, Michelin Pilot Sport Ps2 tires, Apline voice activated NAV w/amp. dyno'd at 625 in 2005, per Gary Hart.
Sounds like a monster. I also read the PDK on the Turbo has proper paddles finally (not the rockers). One for up shift and one for down - and they are paddles.

Man does it suck to spend a lot of money on something and already be pining to upgrade it.

To what speed? If to 60, then highly unlikely as the 996TT is a pain to launch. But should be walking it down fast after that.

The new motor has yet to be vetted. Higher compression will work against heavy modding.
We KNOW the GT1 block is durable. Let's face it, the TT would not be relevant today if it wasn't for the almost limitless modding potential. That, and the bulletproof reliability is what makes a 911 turbo so desirable.
Personally, I wouldn't touch one of the new engined cars for at least a few years.

I agree that the new engine may take some time to get fully sorted. GT1 engine has proven to be a real gem. No doubt Porsche will get this one right also eventually.
I'll bet this motor will not be an issue, there are MANY manufacturer that have built reliable small displacement turbo motors. To think that Porsche wouldn't build and excellent quality one is naive. When they have to replace the NA GT1 block, then there will be reason to doubt, but a turbo engine isn't hard with today's technology from a quality manufacturer like Porsche.
