For those looking to squeeze even more performance out of their 2005 Nissan Frontier NISMO, there are several modifications and upgrades available for the VQ40DE engine. These upgrades can improve horsepower, torque, and overall driving experience. However, it’s essential to choose modifications wisely and ensure they are installed correctly to avoid damaging the engine.

Some popular modifications and upgrades include:

• Cold Air Intake: A cold air intake replaces the factory air intake system with a less restrictive design, allowing the engine to draw in more air. This can improve horsepower and throttle response.
• Performance Exhaust System: Upgrading to a performance exhaust system can reduce backpressure and improve exhaust flow, resulting in increased horsepower and torque. A cat-back exhaust system is a common choice for its balance of performance and affordability.
• Engine Tuning: Custom engine tuning can optimize the engine's performance by adjusting parameters such as fuel injection, ignition timing, and air-fuel ratio. A professional tuner can tailor the engine's settings to your specific needs and driving style.
• Supercharger or Turbocharger: Adding a supercharger or turbocharger can significantly increase horsepower and torque. However, these modifications are more complex and expensive, and they may require additional supporting modifications such as upgraded fuel injectors and a stronger transmission.
• Headers: Upgrading to aftermarket headers can improve exhaust flow and increase horsepower. Long tube headers are generally more effective than shorty headers, but they may require modifications to the exhaust system.

When considering engine modifications, it’s crucial to do your research and choose reputable brands. Read reviews, consult with experienced mechanics, and ensure that the modifications are compatible with your vehicle. Improperly installed or mismatched components can lead to poor performance and even engine damage.

Before making any significant modifications, consider the potential impact on your vehicle's warranty and emissions compliance. Some modifications may void your warranty or make your vehicle fail emissions tests. It’s also essential to ensure that the modifications are legal in your area.
