The performance stats and info for the kit:

"The optic of the car will be the same like before, there are no changes necessary. The nice result is that nobody will know how powerful your car is.
The warranty for the conversion is 2 years, the car is also fully serviceable at your local Porsche Dealer, service can be done like at a 997 Turbo after the conversion.
Both Biturbo conversions for the GT3 are constructed for an “every day use” of the car, in case you have any questions don´t hesitate to contact me.
You are always´s welcome to visit us and also for a testdrive.


Performance - the facts Gturbo 750
0-100 kmph - 3.5 sec.
0-200 kmph - 8.4 sec.
0-300 kmph - 20.6 sec."
I like the testdrive bit!
