I think the silver GTR is running the HKS GT570, and the white one is the Switzer P800....
Regardless, each of these kits cost $25,000+ without tuning. It just comes to show the GTR is beyond anothing I have seen when some good money has been spent on it. Even in stock form its very impressive....
If I had money I think I would go this route....It's just the gear box that scares me shitless. But then again if you can afford the car and the mods then the gear should be the least of your worries!!
