The Nissan 370Z equipped with the VQ37VHR engine has become a popular choice for DIY turbo builds among car enthusiasts. Turbocharging this engine can significantly increase power output, but to achieve optimal performance, it’s essential to consider supporting modifications that enhance reliability and efficiency. In this article, we will explore the top supporting mods for 370Z VQ37VHR DIY turbo builds, focusing on intercoolers, fuel systems, and more.
Intercoolers
Intercoolers play a crucial role in turbocharged engines by cooling the air compressed by the turbocharger before it enters the engine. This cooling process increases air density, allowing for more efficient combustion and improved performance. Here are some top intercooler options for the 370Z VQ37VHR:
- Greddy Front Mount Intercooler: Known for its large core size and efficient cooling capabilities, this intercooler is a popular choice among 370Z owners.
- AMS Performance Intercooler: This intercooler features a lightweight design and excellent cooling efficiency, making it ideal for high-performance builds.
- Stillen Intercooler: Designed specifically for the 370Z, this option provides a perfect fit and significant performance gains.
Fuel Systems
Upgrading the fuel system is essential for turbo builds to ensure that the engine receives adequate fuel to match the increased air intake. Here are some recommended fuel system upgrades:
- Upgraded Fuel Pump: Consider installing a high-flow fuel pump, such as the Walbro 255, to ensure sufficient fuel delivery under boost.
- Fuel Injectors: Upgrading to larger fuel injectors, like the 750cc or 1000cc options, can help meet the increased fuel demands of a turbocharged setup.
- Fuel Pressure Regulator: A quality adjustable fuel pressure regulator can help maintain optimal fuel pressure, especially under boost conditions.
Exhaust Systems
An efficient exhaust system is vital for a turbocharged engine to minimize back pressure and maximize power output. Here are some exhaust system upgrades to consider:
- High-Flow Downpipes: Upgrading to high-flow downpipes can significantly improve exhaust flow and turbo response.
- Cat-Back Exhaust System: A quality cat-back exhaust system, such as those from Stillen or Borla, can enhance sound and performance.
- Test Pipes: Replacing catalytic converters with test pipes can further reduce exhaust restrictions, although this may not be legal in all areas.
Engine Management
Proper engine management is crucial for tuning a turbocharged engine. Here are some options for engine management systems:
- ECU Tune: A custom ECU tune is essential to optimize fuel maps and ignition timing for turbocharged applications.
- Standalone ECU: For those looking for maximum control, a standalone ECU like the AEM Infinity or Haltech Elite can provide advanced tuning options.
- Piggyback ECU: Options like the Nismo or UpRev piggyback systems can be a more affordable way to enhance tuning without replacing the entire ECU.
Intake Systems
Improving the intake system is another critical step in maximizing performance. Here are some intake upgrades to consider:
- Cold Air Intake: A high-quality cold air intake can help increase airflow to the engine, improving throttle response and power.
- Intake Manifold: Upgrading to a performance intake manifold can enhance airflow and distribution to each cylinder.
- Throttle Body Upgrade: A larger throttle body can improve airflow, allowing for better engine performance at higher RPMs.
Cooling Systems
Maintaining optimal engine temperatures is vital for performance and reliability. Here are some cooling system upgrades:
- Upgraded Radiator: A high-performance radiator can help keep engine temperatures in check, especially during aggressive driving.
- Oil Cooler: An oil cooler can prevent oil temperatures from rising too high, ensuring proper lubrication under boost.
- Thermostat Upgrade: A lower temperature thermostat can help maintain optimal engine temperatures during high-performance driving.
Conclusion
Building a DIY turbo setup for the 370Z VQ37VHR can be an exciting and rewarding project. By investing in the right supporting mods, such as intercoolers, fuel systems, exhaust upgrades, engine management, intake systems, and cooling upgrades, you can ensure that your turbocharged engine performs at its best. Always remember to research and choose components that fit your specific goals and driving style for the ultimate driving experience.
