Hey guys! Are you looking to seriously upgrade your Nissan 350Z's performance? Then you've probably heard about the legendary APS twin turbo kit. This setup is renowned for its ability to deliver massive horsepower and torque gains, transforming your Z into a true beast on the street or track. But finding the right kit for sale and knowing what to look for can be a bit of a challenge. So, let's dive into everything you need to know about the APS twin turbo kit for the 350Z, where to find them, and what to consider before you buy.

Unleashing the Power: The APS Twin Turbo Advantage

When we talk about APS twin turbo kits for the 350Z, we're talking about a serious commitment to performance. The key advantage of a twin-turbo system is its ability to provide a broad and responsive powerband. Unlike a single, larger turbo that might suffer from noticeable lag, the twin setup utilizes two smaller turbos. These smaller turbos spool up quicker, delivering boost earlier in the RPM range. This translates to improved throttle response and a more linear power delivery, making your 350Z incredibly fun and engaging to drive in various conditions.

Here's a breakdown of the benefits:

• Enhanced Horsepower and Torque: Expect significant gains, potentially pushing your 350Z well beyond the 400-500 horsepower mark, depending on supporting modifications and tuning.
• Improved Throttle Response: The quicker spooling turbos minimize lag, providing near-instantaneous power when you need it.
• Broader Powerband: Experience a more usable power curve across the entire RPM range, making your Z more versatile for both street and track.
• High-Quality Components: APS was known for using top-notch materials and construction, ensuring durability and reliability.

However, it's crucial to understand that installing a twin-turbo kit is not a simple bolt-on affair. It requires careful planning, professional installation, and supporting modifications to ensure optimal performance and longevity. We'll get into these considerations a bit later.

Hunting for the Kit: Where to Find APS Twin Turbo Kits for Sale

Now for the big question: where can you actually find these kits for sale? Since APS is no longer in operation, finding a brand-new kit is virtually impossible. Your best bet is to explore the used market. Here are some avenues to consider:

• Online Forums: 350Z enthusiast forums are goldmines for finding used parts. Check the classifieds sections on websites like My350Z, Zilvia, and other Nissan-specific forums. Be sure to use specific search terms like "APS twin turbo kit 350Z," "350Z turbo kit," and "used turbo kit." Regularly check these forums, as new listings appear frequently.
• eBay and Other Online Marketplaces: Keep an eye on eBay, Craigslist, and other online marketplaces. These platforms can sometimes yield hidden gems, but exercise caution and thoroughly vet the seller before making a purchase. Look for detailed descriptions, clear photos, and positive feedback.
• Social Media Groups: Join 350Z-specific groups on Facebook and other social media platforms. Members often post parts for sale within these groups. This can be a great way to find deals and connect with other enthusiasts who can offer advice.
• Local Performance Shops: Contact local performance shops that specialize in Nissan vehicles. They may have leads on used APS kits or know of customers who are looking to sell their setups. Building a relationship with a reputable shop can be invaluable.

Important Considerations When Buying Used:

• Condition: Carefully assess the condition of the kit. Look for signs of wear and tear, damage, or missing parts. Ask the seller for detailed photos and descriptions.
• Completeness: Ensure that the kit includes all necessary components, such as turbos, manifolds, intercooler, piping, and hardware. A missing component can be a major headache and add significant cost to the installation.
• History: Inquire about the history of the kit. How many miles has it been used for? Was it properly maintained? Knowing the history can help you gauge its reliability.
• Seller Reputation: Buy from reputable sellers with positive feedback. This will reduce the risk of scams or misrepresentation.
• Price: Research the market value of used APS twin turbo kits. Prices can vary depending on condition and completeness. Be wary of deals that seem too good to be true.

Essential Considerations Before You Buy

Before you jump on the first APS twin turbo kit you find, take a moment to consider these essential factors. Turbocharging your 350Z is a significant undertaking, and proper planning is crucial for a successful outcome.

• Supporting Modifications: An APS twin turbo kit will significantly increase your engine's power output. To handle this increased power, you'll need to invest in supporting modifications. These may include:
  • Fuel System Upgrades: Higher-flowing fuel injectors and a larger fuel pump are essential to deliver the necessary fuel to the engine.
  • Engine Management System: A standalone engine management system (EMS) or a re-tuned ECU is necessary to properly control the engine's parameters, such as fuel, timing, and boost.
  • Clutch Upgrade: The stock clutch will likely not be able to handle the increased torque. A stronger aftermarket clutch is a must.
  • Exhaust System: A high-flow exhaust system will help reduce backpressure and improve performance.
  • Cooling System: Upgrading your radiator and adding an oil cooler will help keep your engine temperatures in check.
• Installation Costs: Installing a twin-turbo kit is a complex and time-consuming process. Unless you have extensive mechanical experience, it's best to have it installed by a professional. Factor in the cost of labor when budgeting for the project.
• Tuning: After the installation, your car will need to be professionally tuned to ensure optimal performance and reliability. Tuning involves adjusting the engine's parameters to match the new hardware. A proper tune is crucial to prevent engine damage.
• Reliability: While the APS twin turbo kit is known for its performance potential, it's important to understand that forced induction can put additional stress on your engine. Regular maintenance and proper tuning are essential to maintain reliability.

Alternatives to the APS Twin Turbo Kit

If you're having trouble finding an APS kit or are looking for other options, there are alternative twin-turbo kits available for the 350Z. Some popular brands include:

These alternative kits may offer similar performance to the APS kit, but it's important to research each option and choose the one that best suits your needs and budget.

Final Thoughts: Is the APS Twin Turbo Kit Right for You?

The APS twin turbo kit for the 350Z is undoubtedly a potent upgrade that can transform your car's performance. However, it's not a decision to be taken lightly.
