Mazda 3 Turbo & Superchargers

A turbocharger is a tried-and-tested way to increase engine performance, improve volumetric efficiency, and provide high torque in a wide RPM range. There is a great variety of turbocharger models that differ by their size and performance, but the main principle remains the same. Inside, a turbocharger consists of two main sections, a turbine and a compressor, which are connected with a metal shaft. The shaft has two impeller wheels located on its ends, one in the turbine and another one in the compressor. Driven by exhaust gases, the turbine wheel makes the shaft and another wheel rotate at very high speed that often exceeds 100,000 RPM.

Creating sufficiently high pressure in the intake manifold of your Mazda 3, the turbocharger gets extremely hot and needs to be cooled by engine oil that also protects the assembly's bearings from friction. Actually, most malfunctions of turbochargers are caused by lubrication issues. These may include oil starvation, contaminated or improperly selected motor oil, etc. Whatever problems with this part you've faced, check out our catalog of Mazda 3 turbochargers, service kits, and other components you may need to restore this system.

Today, the requirements for an internal combustion engine are higher than ever: minimum emissions, maximum power, low fuel consumption, high efficacy within a wide RPM range, etc. Engineers implement lots of interesting solutions to cover all the needs, and forced induction systems belong to the most effective equipment in this regard. Pretty much any modern diesel engine has a turbocharger, and more and more gasoline motors get this tried-and-tested technology to take engine performance to a new level. Ford Focus models also have a turbocharged engine that features direct injection and a variable valve timing system.

Meanwhile, a turbocharger also has its own drawbacks. With this part under the hood, the engine gets more complex, potentially less reliable, and less forgiving if you use the wrong motor oil or don't change it timely. While the engine is running, the turbocharger's impeller spins at an extremely high speed, many times faster than the crankshaft, and it's subject to extreme temperatures and friction. Soon or late, your turbo can start malfunctioning, which results in poor performance, blue or black exhaust smoke from the tailpipe, siren noise, etc. Don't postpone the repair job; if you need quality replacement parts, browse our Ford Focus turbochargers inventory.
