Finding an APS Twin Turbo Kit for Your 350Z: What to Look For

Okay, guys, let's talk about the hunt. Finding an APS twin turbo kit for your 350Z can be an adventure in itself. Since these kits are no longer in production, you'll primarily be looking at the used market. This means doing your homework is crucial. First off, assess the kit's condition. Ask for detailed photos of all components, including the turbochargers, intercooler, piping, and manifolds. Look for any signs of damage, such as cracks, dents, or corrosion. Pay close attention to the turbochargers themselves. Check the compressor and turbine wheels for any chips or wear. Also, inquire about the kit's history. How many miles are on it? What type of driving has it been subjected to? Was it professionally installed and maintained? The more information you can gather, the better equipped you'll be to make an informed decision. It's also worth researching the seller. Are they a reputable member of the 350Z community? Do they have positive feedback from previous buyers? Don't be afraid to ask questions and request additional information. A responsible seller will be happy to provide you with everything you need to feel confident in your purchase. Finally, consider the completeness of the kit. Does it include all the necessary hardware, such as hoses, clamps, and fittings? Are there any missing or damaged parts? While some components can be replaced or sourced separately, it's always best to find a complete kit in good condition. This will save you time, money, and headaches in the long run.

Key Considerations Before You Buy: Making the Right Choice

Before you jump the gun and buy the first APS twin turbo kit you see, let's pump the brakes for a minute. There are a few important things to consider to ensure you're making the right choice for your 350Z and your wallet. First, think about your goals for the car. Are you looking for a weekend track toy, a daily driver with some extra punch, or a full-blown showstopper? The APS kit can deliver impressive power, but it's essential to match the kit's capabilities to your specific needs. Also, consider your budget. While the APS kit is a fantastic upgrade, it's not the only expense you'll incur. You'll also need to factor in the cost of installation, tuning, and potentially other supporting modifications, such as fuel injectors, a fuel pump, and an upgraded clutch. It's also a good idea to have a contingency fund in case any unexpected issues arise during the installation process. Furthermore, think about your mechanical skills and experience. Installing a twin-turbo kit is not a simple bolt-on project. It requires a significant amount of technical knowledge, specialized tools, and patience.

A qualified mechanic can ensure that the kit is installed correctly and that your engine is properly tuned to maximize performance and reliability. Finally, remember that adding a turbocharger to your 350Z will likely affect its reliability and fuel economy. While the APS kit is designed to be as reliable as possible, it's still putting additional stress on the engine. Be prepared to perform regular maintenance and address any potential issues promptly to keep your Z running smoothly.

Installation and Tuning: Getting the Most Out of Your APS Kit

So, you've got your hands on an APS twin turbo kit – awesome! Now comes the crucial part: installation and tuning. This isn't just slapping on some parts; it's a delicate process that requires precision and expertise. Whether you're a seasoned mechanic or entrusting the job to a professional, understanding the process is key. Installation typically involves removing the stock exhaust manifolds, installing the turbochargers, intercooler, and associated piping, and modifying the fuel and ignition systems. It's a time-consuming process that can take several days to complete. Once the kit is installed, the next step is tuning.

Tuning is typically done using a standalone engine management system or a modified version of the factory ECU. A qualified tuner will use a dynamometer to measure the engine's output and make adjustments to the fuel and ignition maps to maximize power and efficiency. Proper tuning is essential to ensure that the engine is not running too lean or too rich, which can lead to damage. It's also important to monitor the engine's vitals, such as air/fuel ratio, boost pressure, and exhaust gas temperature, to ensure that everything is running within safe limits. A well-tuned APS twin turbo kit can deliver impressive power gains and a smooth, responsive driving experience. However, a poorly tuned kit can lead to engine damage and poor performance. That's why it's so important to choose a qualified tuner with experience working with the APS kit and the Nissan 350Z.

This is a more involved and expensive project, but it can result in a significant increase in power and performance. Finally, don't underestimate the power of naturally aspirated modifications. Upgrading the intake, exhaust, and camshafts can significantly improve the engine's breathing and increase horsepower and torque. While these modifications won't deliver the same level of power as a turbo or supercharger kit, they can be a cost-effective way to improve performance and enhance the driving experience. Ultimately, the best alternative to the APS twin turbo kit will depend on your specific goals, budget, and mechanical skills. Research your options carefully and choose the solution that best meets your needs.

Maximizing Your 350Z's Potential: Beyond the Turbo Kit

Okay, so you've got your APS twin turbo kit installed, and your 350Z is now a fire-breathing monster. But hold on, the journey doesn't end there!
