Understanding the Twin Turbo Powerhouse
The concept of twin turbocharging is elegant in its simplicity and devastating in its power delivery. It leverages the exhaust gasses from the engine to spin turbines, which in turn force more air into the engine’s cylinders. The result? A substantial increase in horsepower and torque. The beauty of a twin turbo setup, as opposed to a single turbo, is often more immediate power delivery and potentially better engine balance.
APS, standing for Australian Performance Solutions, has been a respected name in the performance car scene. They’ve made their mark crafting high-quality kits and components for a range of vehicles. Their reputation is built on creating reliable, well-engineered solutions. The 350z APS twin turbo kit specifically caters to the unique needs of the Z’s VQ35DE engine, designed to maximize its potential for performance gains.
Core Components of the Kit: The Building Blocks of Power
The heart of any turbo kit is the components that make it all function. Understanding each element of the 350z APS twin turbo kit is critical.
The choice of turbos is paramount, acting as the lungs of the beast. APS typically selects turbos that are carefully matched to the engine’s characteristics. These turbochargers are often selected for their balance of response and top-end power, meaning the driver gets a thrilling and powerful experience throughout the rev range. The specific turbo model will influence how the engine builds power, affecting the power curve and overall driving feel.
Controlling boost pressure is vital for both performance and engine longevity, and this is where wastegates step in. These valves bypass exhaust gasses away from the turbocharger’s turbine, limiting the boost pressure to a safe level. The APS kit usually includes high-quality wastegates. These components work in tandem with the turbos to ensure consistent power output without damaging the engine.
The intercooler is the unsung hero of the system. It’s responsible for cooling the compressed air from the turbos before it enters the engine. The hotter the air, the less dense it becomes, and less power is generated. A well-designed intercooler, like the one often included in the 350z APS twin turbo kit, can dramatically increase efficiency and power. The intercooler type and size will influence how effectively the engine can make power.
Connecting all these components, the piping and hoses are essential. The APS kit uses high-quality materials that can withstand the heat and pressure generated by the turbo system. This helps ensure the air flows efficiently to the engine. The routing and diameter of these pipes are carefully designed to optimize airflow.
The manifolds and downpipes are crucial components for directing the exhaust gases. The design of these components plays a critical role in how quickly the turbos spool up and how efficiently exhaust gases are evacuated. Typically, the APS kit has manifolds and downpipes that are designed to flow well and promote quick turbo response.
Upgrading the fuel system is a must for a turbo setup to ensure that the engine has an adequate supply of fuel. The APS kit may require upgrading the fuel injectors and the fuel pump or may make recommendations to the type of injectors to use. This ensures that the engine gets the correct amount of fuel to match the increased airflow from the turbos.
Finally, a proper tune is an absolute necessity when installing a turbo kit. The engine’s ECU (Engine Control Unit) must be reprogrammed or a standalone management system must be used to manage the extra air and fuel that is now being introduced into the engine. Without a proper tune, the engine is likely to run poorly, and damage can result. A skilled tuner will adjust various parameters.
