For those who track their cars or participate in spirited driving events, the added power is obviously a huge advantage, allowing for faster lap times and more dynamic handling. It's about taking a sophisticated luxury sport sedan and elevating it to supercar-rivaling levels of performance, all while retaining the comfort and practicality that make the G37 Sedan such a great car in the first place. It’s a journey into boosting your ride’s capabilities and truly making it your own.

Choosing the Right Turbo Kit: What to Look For

Alright guys, let's talk turkey about picking the perfect turbo kit for your 2012 Infiniti G37 Sedan. This is probably the most crucial step, as the quality and design of the kit will directly impact your car's performance, reliability, and the overall installation experience. You can't just grab any old turbo kit off the shelf; you need one specifically designed for the G37's VQ37VHR engine. Look for kits that are known for their high-quality components. This means reputable turbocharger brands like Garrett, BorgWarner, or Precision Turbo. The manifold and downpipes should be made from durable materials like stainless steel to withstand the heat and stress. Don't skimp on intercooler piping either; it should be robust and well-fitted. Consider the kit's design and configuration. Are you looking for a single turbo setup or a twin-turbo setup? The G37 already comes with twin turbos from the factory on some models, but aftermarket kits might offer different arrangements or larger turbos. A single turbo setup can sometimes be simpler and more cost-effective, while twin turbos can offer quicker spool times and a more balanced power delivery. Think about your power goals. Are you aiming for a mild, street-friendly boost of, say, 50-75 horsepower, or are you going for a more aggressive build aiming for 100+ horsepower? Different kits are designed for different power levels. A kit designed for moderate gains will likely use smaller turbos and require fewer supporting modifications than a kit built for extreme horsepower. Supporting modifications are also key. Most turbo kits will require upgrades to the fuel system (injectors, fuel pump) and exhaust system. Some might even necessitate engine internals upgrades if you're pushing serious power. Make sure the kit you choose accounts for these necessary additions or that you budget for them separately. Lastly, research the manufacturer and read reviews. Look for companies with a solid reputation in the performance automotive market, especially those specializing in Nissan/Infiniti platforms. Online forums and enthusiast communities are your best friend here. See what other G37 owners are saying about specific kits, their ease of installation, and their long-term performance. A kit with good customer support and a clear installation manual will save you a lot of headaches. Remember, investing in a quality kit upfront will save you money and frustration in the long run, ensuring your turbocharged G37 Sedan is a reliable powerhouse.

Installation Process: What to Expect

Alright folks, let's talk about the nitty-gritty: the installation process for a turbo kit on your 2012 Infiniti G37 Sedan. Now, I won't lie to you, guys, this isn't a weekend garage job for the faint of heart. It's a complex procedure that requires a good understanding of automotive mechanics, specialized tools, and a fair amount of patience. However, with the right preparation and maybe a helping hand from a knowledgeable friend or a professional shop, it's definitely achievable. The first thing you need is a clean, well-equipped workspace. A lift is highly recommended, but if you don't have one, sturdy jack stands and plenty of clearance are essential. You'll need a comprehensive set of tools, including metric sockets and wrenches, torque wrenches, exhaust bending tools (sometimes), and potentially a welder if any custom fabrication is needed, though most good kits aim to minimize this. The installation typically involves removing many of the stock components to make way for the new turbo system. This often includes the stock exhaust manifolds, intake piping, and potentially some parts of the cooling system to reroute lines. Then comes the mounting of the turbocharger(s), exhaust manifolds, and wastegates. This is where precise fitment is critical. Next, you'll install the intercooler and its associated piping. Proper routing of the intercooler piping is crucial to avoid kinks, leaks, and interference with other engine components. Don't forget the oil and coolant lines for the turbo. These need to be tapped into the engine's lubrication and cooling systems correctly to ensure the turbo stays properly cooled and lubricated. This is a vital step for the longevity of your turbo. The downpipes connect the turbo(s) to the rest of your exhaust system. Depending on your kit, this might involve some custom fitting or modification to your existing exhaust. Finally, you'll reinstall the intake system, connecting it to the turbo's compressor outlet. Don't forget the fuel system upgrades and engine management/tuning. These are not optional! You'll need larger fuel injectors and often a higher-flow fuel pump to deliver the extra fuel required for the increased air volume. The most critical part is the tuning. Your car's ECU (Engine Control Unit) needs to be reprogrammed to manage the air-fuel ratios, ignition timing, and boost levels correctly. This is where a professional tuner comes in. A custom dyno tune is essential to maximize performance and prevent engine damage. Without proper tuning, your expensive turbo kit could quickly turn into an expensive paperweight, or worse, a blown engine. So, while the installation itself is a significant undertaking, the tuning is equally, if not more, important. Plan for at least a full weekend, possibly more, depending on your skill level and the complexity of the kit. If you're not comfortable with any of these steps, seriously consider professional installation. It's an investment in getting it done right the first time.

Tuning and ECU Management: The Key to Performance and Reliability

Okay, guys, let's get serious about the absolute most critical part of putting a turbo kit on your 2012 Infiniti G37 Sedan: the tuning. You've invested in a quality turbo kit, you've possibly spent days installing it, and you're dreaming of that boosted power. But without proper ECU management and tuning, all of that could go south real fast. Think of your car's Engine Control Unit (ECU) as the brain of the operation. It constantly monitors everything – air intake, fuel delivery, ignition timing, engine temperature – and makes adjustments to keep things running smoothly and efficiently. When you add a turbocharger, you're fundamentally changing how the engine breathes. You're forcing in significantly more air, which means you must deliver significantly more fuel to maintain the correct air-fuel ratio. If the ratio is too lean (too much air, not enough fuel), you risk detonation, which is essentially the fuel-air mixture exploding prematurely in the cylinder. This can cause catastrophic engine damage, like cracked pistons or blown head gaskets, in a hurry. On the flip side, if it's too rich (too much fuel), you'll lose power, get poor fuel economy, and potentially foul your spark plugs. ECU tuning is the process of recalibrating the ECU's maps and parameters to account for the added boost pressure, larger injectors, and altered airflow. This involves adjusting fuel tables, ignition timing curves, and boost control strategies. Modern ECUs are complex, and simply uploading a generic
