The engine is a twin turboed VH45DE, a 4.5 liter DOHC V8 found in the U.S. in the infiniti Q45. It is stated to develop 740hp but unfortunately there has been no 1/4 mile times to back it up. Here about all the info that I have found on the car:
Yuki Komiya was the designer and builder of the entire dual turbo, VH-45 V8 car project, including engine upgrades, suspension, body mods and interior. He had some backup help from his 2 car business fellow workers with some of the welding and paint, but he claims that he was "the man" that did virtually all the work. He said his project took 5 years to complete.
Mr. Komiya is 30 years old. His profession is "building custom cars" He and two others run a "tuning shop" in Japan called "RISING" which appears to me, from what he says, to be very active in campaigning super dooper modified, older Nissan based "drag cars" at the main tracks in Japan.
He claims the following for his 450Z HP = 720 hp
Torque = 100 kgm
weight of car = 1080 kg
estimated 1/4 mile time = aproximately 10 sec
"goal drag time: 9 sec flat!!"
