We located in Bangkok , Thailand. %100 of our Manufacturing take place in house. To ensure high quality control and high quality products. Most products are made here locally by our own CNC machines. All shipments will go out from our warehouse here. Shipping worldwide is available at low costs.

Yes. Our parts are reverse engineered from OEM components using 3D scanning and CAD modeling to ensure precise fitment. Watch this short youtube video showing how we 3D scan OEM parts 3D Scanning Automotive Parts https://youtube.com/shorts/PNVXl3r3f7o?si=N_7Ni9efFV0buklj

All Ichiban clear timing covers are designed, developed, and produced in-house at our facility in Bangkok, Thailand. We are the original manufacturer behind the product — not a reseller or rebranded. Our covers are injection molded using high-quality transparent polymer, engineered to withstand engine bay temperatures while providing excellent clarity and durability. The design is reverse engineered from OEM Subaru EJ timing covers to ensure precise bolt-on fitment. Several well-known performance brands and dealers source these covers directly from us, including: • Roger Clark Motorsport (RCM) • PRE Racing • Fuji Racing If you see these clear timing covers offered through selected dealers, they originate from Ichiban Engineering manufacturing. We specialize in in-house development, 3D scanning, CAD modeling, mold design, and production — ensuring consistent quality and fitment across all EJ20 and EJ25 applications.

Our parts are used in track, drift, and high-performance builds worldwide. Our customs run some of the fastest cars on the planet, from the most powerful GR yaris in Australia running 780whp to 2000whp+ 2JZ builds in the USA.

Our turbochargers are engineered with a focus on durability, efficiency, and motorsport-level performance. Each turbocharger begins with precision-machined components and carefully selected materials designed to withstand high exhaust temperatures and boost pressures. Critical components such as the compressor housing, turbine housing, and CHRA assemblies are manufactured to strict tolerances to ensure optimal airflow and reliability. The rotating assembly is dynamically balanced to minimize vibration at high RPM and ensure long-term durability. Compressor and turbine wheels are matched according to the intended power range and application. We design our turbo systems to provide: • Efficient spool characteristics • Stable boost control • High thermal resistance • Consistent performance under track conditions Our goal is not just peak horsepower — but repeatable, reliable power. https://youtu.be/dE-2PD3ZtvI Our Turbochargers line-up is made in house here in Thailand. We have two main lines. Universal turbo line and Bolt-on turbo line. Bolt-on turbochargers are for specific cars to use as a Bolt-on / Stock Frame option which does not requires any changes to the car physically. ECU tunning is always required when upgrading a turbo. For Bolt-on turbochargers both Journal Bearning and Dual-Ball Bearing are available. Our Universal line-up has two catergories : Extreme-Series and Entry Level. The Entry Level units have a Journal bearing CHRA and the Extreme Series have a Dual or Triple Ceramic Ball Bearing CHRA. Compressor wheels are forged 2618 billet aluminium available in both Flank Milling or Point Milling options. Some are Point Milled as standard. All of our turbochargers are being balanced on a Turbo Technics Balancing machine which is made in the UK.

Our Billet Valve Covers are not just the best, they are also the most durable and they don't come with a heavy price. Ichiban makes all the covers from a solid block of 6061 T651 Billet aluminum to the highest standards. Watch the following Youtube video showing how we make our billet valve covers in house !

We test all of our Injectors prior to shipment. we use a machine from ANSU. ANSU is a British company making high standard fuel flow testing machines. All Injectors are tested at 3 Bar ( 43.5 Psi ) and are Dynamically Flow Matched to each other. You will get a spec sheet with all the concerning data for your own specific set. https://static.wixstatic.com/media/undefined

Our injectors are tested up to 10 Bar of fuel pressure ( 147 psi ).
