Can't wait to follow this the next nine months!

What's the difference between the GT2 style 6-speed and a 996 Turbo's G96.50 besides AWD? I selfishly ask because I'll be running the latter with LSD in my build. I've seen 996T's with stock transmission/transaxle running 1,000rwhp.

its a g96/88 gt2 gearbox. its gt2 specific/taller gears. im sure the turbo box is fine for your application.

Check out the more recent videos on "Project Nasty". Joey shares quite a but about aerodynamic improvements to his Carrera

It'll be interesting how you address the radiators on the car. When Porsche went water-cooled, they took advantage of the normally turbulent air that leaves radiators and harnessed it to create air curtains around the normally very turbulent air from the front wheels.

ill go check out those videos. i have a renegade hybrid radiator setup. i plan to take the oem steel hood and hang it on the wall of the shop. but have a carbon fiber hood i made as a replacement and going to try to tastefully vent the radiator up and out over the hood.... but we will see how well that works
