* "Biggest" is subjective: Biggest can refer to the turbo's overall size (housing diameter, impeller size), or the amount of boost it can generate. Larger turbos generally produce more boost at lower RPMs, but are less responsive and can create lag. Smaller turbos are more responsive, but can struggle to make high boost at higher RPMs.
* Engine modifications: The 300ZX's VG30DETT engine has limitations. A bigger turbo will require supporting modifications to handle the increased boost and power. This includes upgrades to the intake, exhaust, fuel system, intercooler, and potentially the engine internals.
* Desired power output: How much power are you aiming for? A larger turbo is needed to make significant power gains.
* Driving experience: A larger turbo will alter the car's driving characteristics. You may experience more lag and slower throttle response, which may not be desirable.
Instead of focusing on "biggest," consider these factors when choosing a turbo for your 300ZX:
* Your budget: Turbos and supporting modifications can be expensive.
* Your driving style: Do you prefer a more responsive car, or one with more power at higher RPMs?
* Your power goals: How much horsepower are you aiming for?
* Reliability: Ensure the turbo and related upgrades are compatible with your engine and will provide a reliable power increase.
Popular turbo options for the 300ZX include:
* Garrett GT28RS: A popular choice for moderate power gains with good responsiveness.
* Garrett GT3076R: A larger turbo that can handle significant power, but may create more lag.
* BorgWarner S200: Known for its efficiency and ability to make significant power.
It's crucial to research and consult with experienced mechanics or tuners to choose the right turbo and supporting modifications for your 300ZX based on your specific needs and goals.
