Tuning & Builds
JDM engine builds, dyno results, ECU tuning, power mods, and complete build showcases
Cusco: The Rally and Chassis Reinforcement Specialist
Cusco built their reputation on rally-grade chassis reinforcement. Their 6-point and 8-point roll cages are Japan's most respected. Their LSDs and sway bars appear on championship cars worldwide.
Blitz: From Boost Controllers to Drift Domination
Blitz started making electronic boost controllers in 1980. They pivoted into a full tuning catalog and a dominant D1 Grand Prix drift program with drivers like Nomura Ken and Tsuchiya.
Mine's Motor Sport: The GT-R Whisperers of Yokohama
Michizo Niikura's Mine's Motor Sport in Yokohama refined rather than rebuilt. Every Mine's GT-R is balanced to 1000-km rally reliability before making a single extra horsepower.
Top Secret: Smokey Nagata's Golden Supra Empire
Smokey Nagata founded Top Secret in 1991 after leaving Veilside. His Gold Supra hit 197 mph on a British motorway, and his V12 Supra remains the wildest engine swap in JDM history.
JUN Auto Mechanic: The Big Power 2JZ Specialist
JUN Auto Mechanic in Tsuchiura has built 2JZ engines since 1990. Their Stroker 3.4 kit, valvetrain components, and hand-balanced rotating assemblies set the global 2JZ tuning standard.
Tomei Powered: The Engine Internals Specialist
Tomei has been making JDM engine internals since 1969. Every serious RB26, 2JZ, or SR20 build eventually uses a Tomei oil pump, cam set, or Expreme Ti exhaust.
Powerhouse Amuse: Titanium Art and the S2000 GT1
Powerhouse Amuse's S2000 GT1 is the definitive tuned S2000 — a Tsukuba time attack legend. Their R1 titanium exhausts are the most copied exhaust design in JDM history.
Nismo: Factory Motorsport Division Become Tuning Legend
Nismo started as Nissan's racing department in 1984. The Omori Factory became the tuning arm, producing the S-Tune/R-Tune/Z-Tune program and the legendary 400R and Z-Tune R34 GT-Rs.
Mugen: Hirotoshi Honda's Works Honda Tuner
Mugen was founded by Hirotoshi Honda, son of Honda's founder, in 1973. The company built Formula Junior cars, Formula 1 engines, and the 240-ps Mugen RR Civic Type R — the fastest factory Civic ever.
HKS: Japan's First and Largest Tuner, Founded 1973
Hiroyuki Hasegawa founded HKS in 1973 making aftermarket turbo kits out of his Shizuoka garage. Today it's Japan's biggest tuning house, with 800+ employees and benchmark drag and time-attack cars.
Spoon Sports: Ichishima's Honda Obsession
Tatsuru Ichishima's Spoon Sports has only ever tuned Hondas. Since 1988, the blue-valve-cover workshop has won Japanese N1 championships and built the Honda aftermarket.
RE Amemiya: The Rotary Whisperer
Isami Amemiya has tuned nothing but rotary engines since 1974. His RX-7 FD3S demo cars remain the global benchmarks for peripherally-ported, street-driven rotary tuning.

Found the car. Understand the handover.
Before making promises about collection, coordinate the inspection, paperwork, seller release and transport. Give each part of the purchase its own check.
