Alright, gearheads, let's talk about something that gets the heart racing: turbocharging your 2012 Infiniti G37 Sedan. This isn't just about adding some extra oomph to your ride; it's about transforming it into a beast. The G37 sedan is already a sweet car, known for its sleek design and spirited performance. But imagine taking that to the next level. A turbo kit can unlock a whole new dimension of power, torque, and overall driving excitement. Now, before you dive headfirst into this upgrade, let's break down everything you need to know. We'll cover the basics, the components, the considerations, and what you can expect from this exhilarating modification. This is for the 2012 Infiniti G37 Sedan Turbo Kit.

Why Turbocharge a 2012 Infiniti G37 Sedan?

So, why even bother with a turbo kit for your 2012 Infiniti G37 Sedan? The answer, in short, is performance. The VQ37VHR engine in this car is already a capable performer, but a turbocharger takes it to another level. Here's a quick rundown of the benefits:

  • Increased Horsepower and Torque: This is the most obvious benefit. A turbocharger forces more air into the engine, which allows for more fuel to be burned, resulting in significant gains in horsepower and torque. Expect a substantial increase, potentially doubling or even tripling the original output, depending on the kit and tuning.
  • Improved Acceleration: More power means quicker acceleration. Your G37 will feel noticeably faster off the line and during passing maneuvers.
  • Enhanced Driving Experience: The surge of power from a turbocharger creates an exhilarating driving experience. It's that feeling of being pushed back in your seat that makes you grin every time you hit the gas.
  • Customization and Personalization: A turbo kit is just the beginning. It opens the door to further modifications and customization, allowing you to tailor the performance to your specific preferences.

However, it's not just about raw power. A properly installed and tuned turbo kit can also improve the overall efficiency of your engine, leading to better fuel economy in certain driving conditions. Plus, the sound! The whoosh of the turbo and the growl of the exhaust are music to any car enthusiast's ears. Installing a turbo kit can create such a significant impact.

Understanding the Components of a 2012 Infiniti G37 Sedan Turbo Kit

Okay, guys, let's get into the nitty-gritty. A turbo kit isn't just one part; it's a carefully engineered system of components that work together to boost your engine's performance. Here's a breakdown of the key elements you'll find in a typical 2012 Infiniti G37 Sedan Turbo Kit:

The Turbocharger

This is the heart of the system. The turbocharger is a turbine-driven forced induction device that uses exhaust gases to spin a turbine wheel, which in turn spins a compressor wheel. The compressor wheel forces air into the engine, increasing the amount of oxygen available for combustion. Turbochargers come in various sizes and designs, each with different characteristics. The size of the turbo will impact the power band, and it will be a crucial decision when buying a turbo kit. Larger turbos typically provide more power at higher RPMs, while smaller turbos offer quicker spool-up and better response at lower RPMs.

The Intercooler

As the compressed air from the turbocharger passes through the intercooler, it cools down. Cooling the air is critical because cooler air is denser, containing more oxygen molecules per unit of volume. This allows for a more efficient combustion process and reduces the risk of engine knock. Intercoolers come in different types, including air-to-air and air-to-water. Air-to-air intercoolers are the most common type for street applications, as they are relatively simple to install and maintain.

The Exhaust Manifold

The exhaust manifold is a crucial component that directs exhaust gases from the engine to the turbocharger. The design of the manifold is important for maximizing the flow of exhaust gases, which impacts the turbocharger's efficiency and overall performance. The exhaust manifold is typically made of cast iron or stainless steel, and it's designed to withstand high temperatures and pressures.

The Wastegate

A wastegate is a valve that controls the amount of exhaust gases that flow through the turbocharger. It does this by bypassing some of the exhaust gases around the turbine wheel. The wastegate is critical for regulating boost pressure and preventing overboosting, which can damage the engine. Wastegates can be internal or external. An internal wastegate is integrated into the turbocharger housing, while an external wastegate is a separate component.

The Blow-Off Valve (BOV) or Diverter Valve (DV)

These valves release excess pressure from the intake system when the throttle closes. They prevent compressor surge, which can damage the turbocharger. A BOV releases the pressure into the atmosphere, creating the iconic
