Increased Horsepower

Who doesn't want more horsepower? A supercharger kit can boost your 370Z's horsepower by a significant margin, making your car not just faster, but also more responsive when you need that extra oomph.

Improved Torque

More torque means better acceleration and a more enjoyable driving experience. With a supercharger, you'll feel the difference every time you step on the gas, whether you're overtaking traffic on the freeway or carving up your local canyon roads.

Incredible Driving Experience

Let's be real; driving a supercharged 370Z is like having your own personal roller coaster. The incredible speed and performance will make every drive an experience you won't want to end.

The Basics of Supercharging

What is a Supercharger?

A supercharger is essentially an air compressor for your engine. It forces more air into the combustion chamber, allowing your engine to burn more fuel and generate more power. It's like upgrading your car's lungs so it can breathe better and make more power.

Types of Superchargers

There are mainly three types of superchargers: Roots, Twin-Screw, and Centrifugal. Each has its own pros and cons, affecting factors like efficiency, noise level, and power curve. Most 370Z kits on the market use a centrifugal supercharger due to the cramped engine bay and design of the V6 engine.

How Does a Supercharger Work?

In simple terms, a supercharger spins at high speeds to draw air into its compressor. This compressed air then gets pushed into the engine's intake manifold, creating a richer air-fuel mixture. The result? More power at your disposal.

Factors to Consider Before Buying a Supercharger Kit

Not all supercharger kits are created equal. Make sure the one you're eyeing is compatible with your specific 370Z model. The last thing you want is to drop cash on a kit that doesn't fit.


Supercharger kits generally cost several thousand dollars. Know your budget and what you're willing to spend for adding performance that a supercharger kit can give your Z.

Installation Complexity

Some kits are plug-and-play, while others may require a bit more mechanical know-how. Consider whether you'll be doing the installation yourself or if you'll need professional help.

Warranty and Support

Always check the warranty and customer support options. A good warranty can save you a lot of headaches down the line, and solid customer support can be a lifesaver if you run into any issues.

Installing Your New Supercharger Kit

Steps for DIY Installation

If you're a hands-on car enthusiast, installing a supercharger kit yourself can be a rewarding experience. You'll need a decent set of tools, a well-lit workspace, and a weekend to get it done. Always start by reading the instruction manual thoroughly. Then, proceed with removing the necessary parts like the front bumper and fender liners, depending on the kit. Make sure to torque all bolts to the specifications given in the manual.

Finding a Qualified Mechanic

If DIY isn't your thing, no worries! Look for a reputable shop that has experience modifying Nissan 370Zs. Check reviews, ask for references, and maybe even visit the shop to get a feel for their expertise. We also recommend having the shop that installs your kit be your tuner as well. ensuring a seamless experience when having your SC kit installed.

Cost Comparison

DIY can save you labor costs, which can range from several hundred to a $1K or more depending on the complexity of the kit. However, if you're not confident in your mechanical skills, the peace of mind from a professional installation could be priceless.

Servicing Your Supercharged Nissan 370Z

Routine Checks

Regularly check the supercharger belt tension and listen for any unusual noises. Keep an eye on your temperature gauges and make sure the intercooler piping is secure.

Common Issues and Solutions

Some common issues include belt slippage and overheating. For belt issues, a simple adjustment or replacement is usually enough. Overheating can often be solved by cleaning the intercooler or upgrading to a more efficient one.

Longevity Tips

Regular oil changes and using high-quality fuel can go a long way in extending the life of your supercharger. Also, consider installing a performance oil cooler if your kit doesn't include one.

Other Nissan 370Z Performance Upgrades

Nissan 370Z Turbo Kits

If supercharging isn't your jam, turbochargers offer another route to high-octane thrills for your 370Z. Unlike superchargers that provide instant power gains, turbo kits can deliver higher peak power but come with their own set of challenges. They're generally more complex to install, requiring additional modifications like a new exhaust manifold and downpipe, and they demand more intricate tuning to get everything just right. So, if you're up for a bit more of a project and are chasing those higher horsepower numbers, a turbo kit could be the way to go.

Nissan 370Z Full Bolt On (FBO) Setups

If you're not quite ready to take the supercharging plunge, Full Bolt-Ons (FBOs) are a killer alternative to level up your 370Z's performance.
