Top Secret Performance Engineering
Top Secret Performance Engineering is a Japanese motor vehicle tuning company that makes performance car parts for Wangan, Circuit, Drag, and Drift forms of racing motorsports. Top Secret has won awards and been featured in many import car tuning magazines. In recent news, Top Secret took home Best of Show honors at the 2007 Tokyo Auto Salon for their “Final Evolution” JZA80 wide body kit V12 twin turbo Toyota Supra.
Founder, owner, and active president Kazuhiko “Smoky” Nagata has been tuning and creating performance vehicles under the Top Secret name since the mid 90’s. The first tuned cars Kazuhiko Nagata created under the Top Secret name were green in color but later, after finding inspiration from the Olympics and the gold medal, Nagata decided to use gold paint to distinguish the Top Secret cars.
Aside from tuning and building incredible cars, Kazuhiko “Smoky” Nagata is known for reaching extreme top speeds, like 340 km/h (211 mph), on highways and public roads. Some of these street racing exploits have been captured by Video Option and make for some awesome street racing videos.
Top Secret specializes in car parts like body kits, electronics, engine parts, exhaust, suspension, turbo kits, and wheels for JDM import cars. They are also known for their custom tuning. If you want, you can ship your car to Japan to have Smoky Nagata tune it at Top Secret’s Shop, or, Nagata can come to you! One thing is clear when admiring Top Secret’s vehicle portfolio…these guys love fast cars!
