What Tomei Powered does

Tomei Powered Inc. (東名パワード) is a Japanese specialty manufacturer founded in 1968 by Seiichi Suzuki, a Nissan Works Team Driver, alongside fellow members of the JOHOKU RIDERS car club. The company designs, engineers, and produces precision high-performance internal combustion engine components and exhaust systems, with deep specialization across Japanese engine families including Nissan RB26/SR20/VQ, Toyota 1JZ/2JZ, Subaru EJ/FA, Mitsubishi 4G63, and Honda platforms. Core technology spans forged crankshafts, pistons, H-beam connecting rods, camshafts (PONCAM/PROCAM series), multi-layer steel head gaskets, turbocharger kits (ARMS series including T400M and T440M), high-flow cast turbo outlet pipes, and proprietary titanium exhaust systems (Ti RACING, Ti SPORTS, EXTRACK Ti) with in-house titanium material sourcing and processing from raw material through finished product. The company also offers complete engine assembly and tuning services including engine overhaul, head combination, and valve work.

The business model is multi-stream and primarily hardware-based: one-time unit sales of performance parts at price points ranging from ¥2,500 for small accessories to over ¥1,000,000 for complete stroker kits, plus professional tuning services and branded merchandise. Revenue is generated through three complementary go-to-market motions: (1) direct-to-consumer e-commerce via the tomei-p.stores.jp online storefront, (2) an extensive authorized dealer network across Japan including specialized tuning shops (Project Fine, TOP SECRET, Zeigen) and the Super Autobacs retail chain, and (3) a network of international distributors spanning 25+ countries across Asia-Pacific, Europe, the Middle East, and Africa. The company also distributes third-party performance brands including ARP fasteners, DW/DEUTSCHWERKS fuel components, HOLINGER drivetrain parts, and PLX data acquisition equipment as part of a bundled offering. Pricing is publicly disclosed in Japanese Yen, with a broad price revision implemented in July 2026 due to increased costs.

Customer segments span professional racing teams and constructors, professional tuning shops, automotive parts retailers, and individual automotive enthusiasts engaged in performance modifications and motorsports. The company operates under sub-brands including PONCAM, PROCAM, EXPREME, EXPREME Ti, Ti RACING, Ti SPORTS, EXTRACK Ti, ARMS, and TECHNICAL TRAX ADVANCE, with corporate branding identifying Tomei as "The Engine Specialist." The company is privately held with no external funding rounds and no public listing, affiliated with GLION Group through recruitment channels.
