The Nissan 350Z is a popular sports car known for its sleek design and impressive performance. For enthusiasts looking to push the limits of their vehicle, building a 350Z with a VQ35DE engine to achieve 500 horsepower is an exciting challenge. This article will explore the necessary turbo kits, fuel system upgrades, and supporting modifications required to reach this ambitious power goal.
Understanding the VQ35DE Engine
The VQ35DE engine is a 3.5-liter V6 that offers a solid foundation for performance modifications. It features an aluminum alloy block and DOHC design, which contributes to its lightweight and efficient performance. To achieve 500 horsepower, significant upgrades will be necessary.
Turbo Kits for the VQ35DE
One of the most effective ways to increase horsepower in the VQ35DE is by installing a turbo kit. Several options are available, each with its own benefits and considerations.
- Greddy Twin Turbo Kit: Known for its reliability and power output, this kit is a popular choice among enthusiasts.
- JWT Twin Turbo Kit: This kit offers a balance of performance and price, making it a solid option for those looking to upgrade.
- HKS GT2835 Turbo Kit: This kit is designed for those who want to maximize their power potential with larger turbos.
Fuel System Upgrades
To support the increased power from a turbocharged VQ35DE, upgrading the fuel system is crucial. This includes larger fuel injectors, a high-flow fuel pump, and an upgraded fuel pressure regulator.
- Fuel Injectors: Consider 750cc or larger injectors to ensure adequate fuel delivery at high power levels.
- Fuel Pump: An upgraded fuel pump, such as the Walbro 255, can provide the necessary fuel flow for turbo applications.
- Fuel Pressure Regulator: A high-performance regulator will help maintain consistent fuel pressure under boost.
Supporting Mods for 500 HP
In addition to turbo kits and fuel system upgrades, several supporting modifications are essential for achieving 500 horsepower safely and reliably.
- Upgraded Intercooler: A larger intercooler will help reduce intake temperatures, improving performance and reliability.
- Exhaust System: A high-flow exhaust system will reduce back pressure and improve turbo spool time.
- Engine Management: A standalone ECU or reflash is necessary to optimize fuel and timing maps for the new setup.
- Stronger Clutch: Upgrading to a performance clutch will handle the increased power without slipping.
- Suspension Upgrades: Improved suspension components will enhance handling and stability at higher speeds.
Conclusion
Building a 350Z VQ35DE to 500 horsepower is an ambitious yet rewarding project. By selecting the right turbo kit, upgrading the fuel system, and incorporating supporting modifications, enthusiasts can achieve impressive performance. Always ensure that modifications are performed with care and consider professional installation for complex components.
