SHOWA Co.,Ltd. List of Products and Services

At Showa Co., Ltd., we provide maintenance and sales of turbochargers across a wide range of fields, from passenger cars to trucks, industrial machinery, and marine applications. As an authorized dealer for BorgWarner and Garrett, we deliver reliable maintenance services. Since our establishment, we have specialized in the repair and rebuilding of fuel injection pumps and turbochargers. If you have any concerns, please feel free to consult us. 【Manufacturers We Handle】 ■ BorgWarner ■ Garrett ■ IHI (Clover Turbo) ■ MHI (Mitsubishi Heavy Industries) ■ HITACHI ■ Cummins Turbo Technologies (HOLSET) 【What is Rebuilt?】 Rebuilt parts refer to machine components that have been regenerated. Utilizing specialized regeneration technology, rebuilt products can be restored to performance levels comparable to new ones. In recent years, there has been a growing commitment to promoting recycling on a global scale, and "turbochargers and injection pumps as rebuilt products" has already become a new norm. *For more details, please refer to the PDF materials or feel free to contact us.

A turbocharger is a type of air pump that reuses the energy from engine exhaust gases that would normally be wasted. The exhaust gases first drive the turbine wheel assembly. This part is connected to the compressor wheel. As the connected compressor wheel rotates, it is possible to send a large amount of air into the engine's combustion chamber in a compressed state. Since the compressed air has increased density, it allows for more fuel to be injected, which is why a turbocharged engine can produce greater horsepower than a non-turbo engine of the same size. *For more details, please refer to the PDF document or feel free to contact us.*

Turbocharger failures are mostly caused by external factors. Despite failures caused by reasons other than the turbocharger, if the abnormalities are not detected and there are no countermeasures, replacing the unit will lead to similar failures. 【Examples of Turbo Failure Causes】 ■ Troubles related to lubricating oil ■ Damage due to foreign object intrusion on the intake or exhaust side ■ Contamination of lubricating oil with foreign substances ■ Poor engine compression and blow-by ■ Excessive rise in engine exhaust temperature ■ Troubles due to installation errors ■ Malfunction of the actuator 【About Us】 At Showa Co., Ltd., we provide "rebuilt technology" that utilizes specialized regeneration techniques as an authorized dealer for turbo manufacturers worldwide, regenerating mechanical parts to a quality comparable to new. We cater to a wide range of needs from light vehicles to imported cars, trucks, construction machinery, and ships. *If you have any issues with turbos or injection pumps, please consult us first!

The turbo of a turbocharger spins at high speeds of about 100,000 to 250,000 RPM. What happens if the balance is off? Unbalanced tires cause vibrations and result in a very uncomfortable ride. In the case of a turbo, if it is unbalanced, not only will it fail to perform at its best, but in the worst case, it can lead to damage issues. Our company uses two types of balance testers to perform balance corrections with higher precision than new ones. Please feel free to consult us. *For more details, please refer to the PDF document or feel free to contact us.

Our company also supports three components of the common rail system: "high-pressure pump," "accumulator rail," and "injector." The high-pressure pump is responsible for pressurizing the fuel and sending it to the rail. If it fails, it cannot create the proper pressure, leading to issues such as engine starting difficulties. Some repairs may be possible, so please contact us. The accumulator rail acts like a tank that stores high-pressure fuel. Easy repairs are dangerous and generally not possible. It is common to replace it with a new one. The injector is the most critical component of the common rail system, performing the complex task of injecting fuel into the cylinder. Typically, the only option is to replace it with a new part, but we will provide suggestions using all possible methods. If you are in need, please feel free to consult with us. *For more details, please refer to the PDF materials or feel free to contact us.*

At Showa Corporation, we provide maintenance and sales of turbochargers across a wide range of fields, including passenger cars, trucks, industrial machinery, and marine vessels. We are pleased to announce that we have signed a contract with Continental as an after-sales agent in Japan in 2020. We have become a domestic agent responsible for selling turbochargers manufactured and supplied by Continental as OEMs for the aftermarket! 【Compatible Vehicle Manufacturers】 BMW / MINI / VW / AUDI Since we import directly from Continental, we can offer new genuine products at competitive prices. *For more details, please refer to the PDF document or feel free to contact us.

At Showa Co., Ltd., we provide maintenance and sales of turbochargers across a wide range of fields, from passenger cars to trucks, industrial machinery, and marine applications. We would like to introduce the overseas manufacturers of turbochargers for which we serve as the official distributor. 【Official Distributors of Overseas Manufacturers: Turbochargers】 ■ BorgWarner (KKK, Schwitzer) / BorgWarner ■ GARRETT / Garrett ■ Continental / Continental Our company is the only one in Japan that offers a multi-brand lineup from the above three companies. *For more details, please refer to the PDF materials or feel free to contact us.

Continental, well-known for its tires, also produces turbochargers as OEM. Here, we would like to introduce the features of the "Continental Turbocharger." Our company signed a contract with Continental in 2020 as the after-sales agent in Japan and is recognized as an official distributor in the country. The exhaust side housing, which is typically made of heat-resistant alloy (with iron as the main component), is made of "aluminum" in the Continental turbocharger model. Although the exhaust temperature exceeds 700 degrees, using a water-cooling system resolves the thermal issues associated with aluminum. Additionally, it allows for the cooling water to be heated in a short time. ★ We also provide OEM turbochargers for small gasoline vehicles, including BMW, AUDI, and FORD. 【Product Features】 ■ Cost reduction ■ Weight reduction ■ Accelerates the rise in engine oil and cooling water temperature ■ Suppresses oil sludge generation *For more details, please refer to the PDF materials or feel free to contact us.

At Showa Corporation, we provide maintenance and sales of turbochargers across a wide range of fields, including imported cars, trucks, industrial machinery, generators, agricultural machinery, and marine applications. * We do not discriminate between domestic and overseas products! < Introduction of our hiring achievements > Engines for passenger cars, trucks, and buses / Various generators, overseas biomass generator engines Marine (ship) engines / Agricultural machinery engines / Imported special machinery, etc... < Inquiries related to imported engines > ◎ Unable to find a domestic maintenance company because it’s an overseas product... ◎ No company can handle repairs due to the old model of the engine... ◎ Considering purchasing an overseas engine, but the price does not match with the vendor... ◎ Would like to request "rebuilt" machinery parts instead of repairs... ◎ Looking for new parts but struggling with high prices... ◎ Searching for a vendor that can handle regular maintenance ⇒ We may be able to solve such concerns for you! * Start with a consultation!
