The owner of this 427 ci LSx powered Infiniti G35 brought it to D3 Performance in Houston, Texas for more power, a lot more power. The goal was to create a twin-turbo setup capable of 1,500+ whp to compete in roll-racing events and TX2K. To meet that goal D3 Performance installed a pair of Precision 7175 turbos, a 4L80E automatic transmission for quick shifts, and a Pro EFI 128 system to control it all. If you are fan of pretty TIG welds you will enjoy going through the images on the this build.
