The manual gearbox is a good new, I am no fan of the SMG/DSG/F1/PDK gearboxes on a sportcar.

But 6500, that is very very soon.. Great deception. Can't call that a high-revver engine like the GT3...
First off, why do you want to rev to 8K RPM? Are you saying that all sports cars have to be high revving? Secondly, and more importantly, is the fact that the GT2 is turbo charged, so it makes a lot more power and torque at much lower RPMs. This is because the turbo chargers force extra air into the cylinder allowing the engine to burn more fuel during each cycle giving you greater power per cycle (RPM). The GT3 revs so much higher because it's trying to get attain more HP by increasing the number of power cycles (RPMs) because it can't increase the amount of oxygen in its cylinders above the ambient air pressure. The GT2 doesn't need to rev to 8K to find power. It makes more HP than a GT3 below 5k RPM. The GT2 also has almost twice the torque of the GT3 across its entire power band. It will pull hard in any gear at any engine speed. Why rev if you don't have to?
