Turbocharging for Any Application

From small-displacement street cars to high-horsepower race machines, Summit Racing turbochargers are engineered to fit a wide range of builds. Choose from various compressor and turbine sizes to match your power goals, driving style, and engine setup.

Efficient Power Delivery

Our turbos are designed with high-efficiency compressor wheels and advanced turbine housing geometry to move more air with less lag, giving you quick throttle response and a strong, sustained pull through the powerband.

Built to Handle the Pressure

Summit Racing turbochargers are manufactured from premium materials, with heat-resistant turbine housings and precision-balanced rotating assemblies to ensure smooth, reliable operation under extreme boost pressures.

Options for Every Build

Choose from journal bearing designs for cost-effective durability or ball bearing setups for lightning-fast spool and reduced friction. Many models are available with your choice of an internal or external wastegate housing for easy boost control.

Engineered for Reliability

Each turbo is rigorously tested to ensure it meets strict performance and quality standards. From the compressor housing to the turbine wheel, every component is optimized for long life and consistent performance—so you can spend more time driving and less time wrenching.

FAQ Section:

Q. How does a turbo work?

A. A turbocharger uses exhaust gases from your engine to spin a turbine wheel, which is connected by a shaft to a compressor wheel. The compressor draws in and compresses fresh air before sending it into the engine’s intake manifold. By forcing more air into the cylinders, the engine can burn more fuel, creating significantly more power compared to natural aspiration—all without requiring additional engine displacement.

Q. Can a turbo damage your engine?

A. A properly matched and installed turbo will not harm your engine, but excessive boost pressure or poor tuning can cause detonation, overheating, or bearing failure, and inadequate fuel delivery or insufficient cooling can lead to problems. Running too much boost for your engine’s compression ratio, ignoring proper oiling requirements, or using low-quality components can lead to parts failure. Correct tuning, high-quality parts, and regular maintenance are key to turbo reliability.

Q. How much horsepower will a turbocharger add?

A. It depends on the size of the turbo, your engine’s displacement, compression ratio, fuel system, and tuning. A mild street setup might add 30–70% more horsepower, while a well-built performance engine with a larger turbo can see gains of 100% or more. The goal is to choose a turbo sized for your power target without sacrificing drivability.

Q. How often do turbos need to be serviced?

A. Most modern turbos are designed to last well over 100,000 miles with proper care. Regular oil changes with high-quality oil, ensuring your air filter is clean, and allowing the turbo to cool down after hard driving will greatly extend its life. If you notice excessive smoke, whining noises, or a drop in boost pressure, it may be time for inspection or rebuilding.
