FAQ Section

Q1: Why is upgrading the fuel pump important for an R32 GTR’s performance and reliability?
A1: The stock fuel pump in an R32 GTR was designed for the factory horsepower levels. When you start adding modifications like more boost, larger turbos, or tuning for more power, the original pump can’t supply enough fuel. This leads to lean conditions, which are very dangerous for your engine and can cause severe damage. An upgraded R32 GTR fuel pump ensures your engine gets the consistent, adequate fuel flow it needs for safe and reliable performance under increased demands.

Q2: What flow rate (LPH) should I look for in an R32 GTR fuel pump?
A2: For moderately modified R32 GTRs (targeting around 350-450whp), a 255LPH (liters per hour) fuel pump is generally sufficient and a very popular upgrade. If you’re planning on pushing more power (500-600+ whp), running larger turbos, or using E85 fuel, a 340LPH or even higher flow rate pump would be a safer and more future-proof choice for your R32 GTR fuel pump to maintain adequate supply.

Q3: Can I install a new fuel pump in my R32 GTR myself?
A3: Installing an R32 GTR fuel pump can be a DIY job if you’re comfortable working with fuel systems, have the right tools, and understand safety procedures. It often involves removing the back seat, accessing the fuel tank, and disconnecting fuel lines and electrical connectors. However, because it deals with flammable fuel and critical engine components, professional installation is highly recommended if you’re unsure, to ensure proper sealing, wiring, and safety.

Q4: Do I need to upgrade other fuel system components when installing a high-performance R32 GTR fuel pump?
A4: Often, yes. While the fuel pump is key, a complete fuel system upgrade might include a new, high-quality fuel filter (to protect your new pump and injectors), larger fuel lines (for very high horsepower), an adjustable fuel pressure regulator, and potentially bigger fuel injectors. It’s also crucial to ensure your wiring and the fuel pump relay are adequate for the higher current draw of an upgraded R32 GTR fuel pump to prevent voltage drop and pump damage.

Q5: What’s the difference between an in-tank and an in-line fuel pump, and which is best for my R32 GTR?
A5: An in-tank fuel pump is located inside the fuel tank, submerged in fuel. This helps keep it cool and quiet. Most R32 GTRs come with an in-tank pump, and most performance upgrades are also in-tank replacements. An in-line fuel pump is mounted outside the fuel tank, along the fuel line. In-line pumps are often used as secondary pumps in very high horsepower setups or when an extremely high-flowing pump can’t fit in the tank. For most R32 GTR performance and reliability upgrades, an in-tank pump is the preferred and simpler solution.

Q6: How do fuel filters and relays affect the performance and reliability of an R32 GTR fuel pump?
A6: Fuel filters are critical for reliability; they prevent dirt, rust, and debris from reaching and damaging your R32 GTR fuel pump and injectors. A clogged filter can restrict fuel flow, causing your pump to work harder and potentially lead to fuel starvation. Fuel pump relays control the electrical current to your pump. An old or weak relay can cause a voltage drop, reducing the power reaching your pump. This means your high-performance pump won’t operate at its full capacity, leading to reduced fuel flow and potential reliability issues. Upgrading both when you install a new R32 GTR fuel pump is highly recommended.
