So, you're looking to inject some serious adrenaline into your 2012 Infiniti G37 sedan? You've come to the right place, guys! A turbo kit is the way to transform your already sweet ride into an absolute rocket. But before we dive headfirst into the world of boost, let's break down what a turbo kit actually is, why it's such a game-changer for your G37, and what you need to consider before slapping one on. We will cover the basics first, the benefits, considerations, and what to look for when selecting the perfect turbo kit. By the end of this article, you'll be well-equipped to make an informed decision and get ready to experience your G37 in a whole new dimension of performance.

What is a Turbo Kit, Anyway?

At its heart, a turbo kit is all about forcing more air into your engine. Your engine runs on a mixture of air and fuel, and the more air you can pack in, the more fuel you can burn, resulting in a massive increase in power. A turbocharger is essentially an air compressor that's powered by the exhaust gases coming from your engine. These gases spin a turbine, which in turn spins a compressor that forces air into the engine's cylinders. Think of it like giving your engine a super-powered set of lungs! Now, a turbo kit isn't just the turbocharger itself. It's a comprehensive package that includes all the necessary components to make the system work seamlessly and reliably. This typically includes:

• The Turbocharger: The star of the show, responsible for compressing the air.
• Intercooler: Cools the compressed air, making it denser and further increasing power.
• Piping: Connects the turbocharger to the engine's intake manifold.
• Wastegate: Regulates the amount of exhaust gas that flows through the turbine, controlling boost pressure.
• Blow-Off Valve (BOV) or Diverter Valve: Releases excess pressure when you let off the throttle, preventing damage to the turbocharger and creating that awesome whooshing sound.
• Fuel Injectors: Larger injectors to supply the increased fuel demand.
• Engine Management System (EMS) or Piggyback ECU: To properly tune the engine for the added boost.
• Various Hoses, Clamps, and Fittings: All the necessary hardware for a complete installation.

Why Turbocharge Your 2012 Infiniti G37 Sedan?

The Infiniti G37 is already a fantastic car, boasting a potent VQ37VHR engine known for its smooth power delivery and rev-happy nature. So, why mess with a good thing? Well, the answer is simple: more power! While the G37 has a decent amount of horsepower from the factory, a turbo kit can unlock a whole new level of performance, transforming it from a sporty sedan into a true performance beast. Here's a breakdown of the benefits:

• Significant Power Increase: This is the most obvious benefit. A well-designed turbo kit can add anywhere from 100 to 200+ horsepower to your G37, depending on the boost level and supporting modifications.
• Improved Acceleration: With the added power, your G37 will accelerate much faster, making it a thrill to drive on the street or track.
• Enhanced Torque: Turbocharging not only increases horsepower but also significantly boosts torque, especially in the mid-range. This translates to better throttle response and effortless acceleration in everyday driving situations.
• Increased Fun Factor: Let's be honest, who doesn't love the sound of a turbocharger spooling up and the feeling of being pushed back in your seat as the boost kicks in? A turbo kit simply makes your G37 more exciting and engaging to drive.
• Head-Turning Appeal: A turbocharged G37 is sure to grab attention wherever you go. The subtle (or not-so-subtle) sound of the turbocharger and the added performance will let everyone know that your G37 is not your average sedan.

Considerations Before You Turbocharge

Okay, so you're probably itching to slap a turbo kit on your G37 right now, but hold your horses! Before you take the plunge, there are several important factors to consider:

• Budget: Turbo kits aren't cheap. A quality kit can cost anywhere from $4,000 to $10,000 or more, depending on the brand, features, and included components. And that's just the cost of the kit itself. You'll also need to factor in the cost of installation, tuning, and any supporting modifications.
• Installation: Unless you're a highly experienced mechanic with extensive knowledge of turbocharging systems, it's best to have a professional install the kit. Installation can be complex and time-consuming, and if not done correctly, it can lead to serious engine damage.
• Tuning: This is arguably the most critical aspect of turbocharging. Your engine's ECU needs to be properly tuned to account for the added boost. This involves adjusting fuel delivery, ignition timing, and other parameters to ensure that the engine runs safely and efficiently. A poor tune can lead to detonation, engine damage, and reduced performance. You'll need to either get a standalone ECU, or piggyback to manage the fuel/air ratio.
• Supporting Modifications: Depending on the amount of boost you plan to run, you may need to upgrade other components of your G37 to handle the added power. This may include:
  • Fuel System Upgrades: High-flow fuel pump, larger fuel injectors.
  • Exhaust System Upgrades: Higher flowing exhaust to reduce backpressure.
  • Cooling System Upgrades: Upgraded radiator, oil cooler.
  • Transmission Upgrades: Depending on how much power you are planning to make, you may need to upgrade your transmission, torque converter (for automatics) or clutch (for manuals).
  • Brake Upgrades: More power means you need more stopping power.
• Reliability: While a well-designed and properly installed turbo kit can be reliable, it's important to understand that it will put additional stress on your engine. This can potentially shorten the lifespan of certain components, especially if you're running high boost levels.
• Emissions: Turbocharging can affect your vehicle's emissions. Make sure to check your local laws and regulations to ensure that your modified G37 is still compliant.

Choosing the Right Turbo Kit for Your G37

With so many turbo kits on the market, choosing the right one for your 2012 Infiniti G37 sedan can feel overwhelming. Here are some key factors to consider:

• Quality and Reliability: Stick with reputable brands that have a proven track record of producing high-quality and reliable turbo kits. Do your research, read reviews, and talk to other G37 owners who have experience with turbocharging.
• Completeness: Make sure the kit includes all the necessary components for a complete installation. A comprehensive kit will save you time and money in the long run.
• Turbocharger Size: The size of the turbocharger will determine the amount of boost it can produce and the engine's power output. A smaller turbocharger will spool up quickly and provide good low-end torque, while a larger turbocharger will deliver more top-end power but may suffer from turbo lag (a delay in power delivery).
• Intercooler Type: The intercooler is responsible for cooling the compressed air, which is crucial for maximizing power and preventing detonation. There are two main types of intercoolers: air-to-air and air-to-water. Air-to-air intercoolers are simpler and more affordable, while air-to-water intercoolers are more efficient but also more complex and expensive.
• Engine Management System (EMS): A proper engine management system is essential for tuning your engine for the added boost. You can either use a standalone EMS or a piggyback ECU. Standalone EMS systems offer more flexibility and control, but they are also more expensive and require more expertise to tune. Piggyback ECUs are more affordable and easier to install, but they may not offer as much control.
• Your Goals: What are you hoping to achieve with your turbo kit? Are you looking for a modest power increase for everyday driving, or are you aiming for all-out performance on the track? Your goals will help you determine the right turbocharger size, boost level, and supporting modifications.
