Trust GReddy Performance Tuning Parts: Japan's Aftermarket Benchmark
Trust Co., Ltd., operating under the GReddy brand, is one of Japan's most respected performance parts manufacturers. Founded in 1977 in Higashiosaka, Japan, GReddy has supplied turbocharger systems, exhaust components, suspension parts, and engine management solutions to enthusiasts and professional racing teams worldwide. For buyers sourcing JDM performance parts in 2025-2026, GReddy remains a top-tier choice for both factory-fresh components shipped from Japan and used parts from auction vehicles.
Core GReddy Product Lines
Turbocharger Systems
GReddy turbo kits are engineered for bolt-on installation on popular JDM platforms. The TD06SH-25G suits Nissan SR20DET and RB engines supporting 400-450 whp, retailing at approximately 180,000-220,000 yen (USD 1,200-1,500). The T518Z targets Mitsubishi 4G63 builds at 350-400 whp for around 150,000 yen. GReddy also offers a complete turbo kit for the GR86 and BRZ FA24 engine, pushing the 2.4L flat-four to over 350 hp on 93 octane fuel.
Exhaust Systems
The Revolution RS and Evo3 exhaust lines are GReddy's most widely exported products globally. Both feature stainless steel construction and are popular in the Middle East, Southeast Asia, and Australia. The Revolution RS cat-back is available for over 80 vehicle applications starting at 55,000 yen (approx. USD 370), while the Evo3 titanium-finish variant runs 75,000-90,000 yen.
Suspension: Type-S Coilover System
The Type-S coilover kit offers street-focused adjustable suspension for most JDM platforms from 2000 onwards. Spring rates run front 6-8 kg/mm, rear 5-7 kg/mm depending on application. A full set retails at approximately 120,000-160,000 yen from Japanese distributors — significantly cheaper than buying through overseas resellers.
Intercoolers and Intake Systems
GReddy front-mount intercoolers (FMIC) are widely used on Supra, Skyline GT-R, and Evo builds exported from Japan. The bar-and-plate core design offers excellent heat dissipation for tropical and high-ambient-temperature markets common in export destinations.
Buying From Japan vs. Local Market
Sourcing GReddy parts directly from Japan offers a 25-40% price advantage over regional distributor pricing in the UK, US, or Australia — even after factoring in shipping. As of 2026, shipping GReddy coilovers (approx. 20 kg) from Japan via sea freight to the UK costs around USD 80-120 in a consolidated shipment. Yahoo Auctions Japan and Japanese wholesalers are the best channels for both new and lightly used GReddy components.
Identifying Genuine GReddy Parts
Counterfeit GReddy products, particularly exhaust tips and intercoolers, circulate on third-party marketplaces. When purchasing, verify the GReddy holographic authentication sticker on the product box, confirm the part number against the official catalogue at trust-power.com, and check TIG weld quality on exhaust components. Counterfeit intercoolers are typically noticeably lighter due to thinner core construction.
2026 Market Context
Japan's stricter shaken emissions inspections introduced in 2024 have pushed more lightly used GReddy components onto the secondhand market via auctions and Yahoo Auctions Japan. The GR86, GR Yaris, and Nissan Z (RZ34) have revitalized the sport compact tuning segment, and GReddy has dedicated product lines for all three platforms. The weak yen (148-155 per USD through 2025-2026) also enhances the value proposition for overseas buyers purchasing in strong currencies.
