The VR38DETT engine found in the Nissan GT-R R35 is a high-performance twin-turbocharged engine that requires careful and regular maintenance to ensure reliable operation and long life. Here are the key aspects of VR38DETT engine maintenance:

1. Engine Oil and Filter Change

Frequency: Change the engine oil every 5,000-7,000 km or every 6 months, whichever comes first. If the car is used on the track, reduce the change interval to 3,000 km.

Oil: Use only high-quality synthetic motor oil recommended by the manufacturer (usually 5W-30 or 0W-40 viscosity oils).

Filter: Change the oil filter every time the oil is changed. Use genuine or recommended filters to ensure proper oil filtration.

2. Coolant

Checking the level: Check the coolant level regularly and top up as needed.

Replacement: Change the coolant every 2-3 years or every 50,000 km. Use only genuine coolant suitable for the VR38DETT.

Additional Cooling: For track use, consider installing an additional radiator to improve engine cooling.

3. Turbochargers

Check condition: Regularly check turbochargers for oil leaks and signs of wear. Listen to the engine for unusual noises that may indicate problems with the turbochargers.

Oil change: Keep engine oil clean and of good quality, as turbochargers depend on effective lubrication. Clean oil will help prevent wear and damage to turbochargers.

4. Spark plugs

Change interval: Change spark plugs every 40,000-50,000 km or more often if the vehicle is used hard.

Spark plug type: Use only high-quality iridium or platinum spark plugs recommended by the manufacturer. They provide consistent ignition and durability.

5. Fuel system

Injector cleaning: Regularly use fuel additives to clean injectors and maintain their efficiency. Have injectors professionally cleaned every 60,000-80,000 km.

Filter: Change the fuel filter every 40,000-60,000 km to prevent fuel system clogging.

6. Intake System

Filter: Change the air filter every 20,000-30,000 km, or more often if operating in dusty conditions.

Intake System Cleaning: Periodically clean the intake system of carbon deposits, especially if you notice a loss of power or poor engine performance.

7. Exhaust System

Exhaust System Inspection: Regularly inspect the exhaust system for leaks and damage. Make sure the catalytic converters and oxygen sensors are functioning properly.

Sensor Replacement: It is recommended to replace oxygen sensors every 100,000 km or at the first sign of malfunction.

8. Belt and Hoses Inspection

Visual Inspection: Periodically inspect belts, hoses, and other components for wear, cracks, or leaks.

Replacement: Replace the drive belts every 80,000-100,000 km or when signs of wear appear.

9. Diagnostics and Flashing

Periodic Diagnostics: Use diagnostic equipment to check the condition of the engine and control systems. Monitor error codes and resolve them as soon as possible.

Flashing: Update the ECU (Engine Control Unit) firmware according to the manufacturer's recommendations to improve performance and eliminate potential problems.

10. Boost Control

Routine Checks: Monitor the boost pressure and ensure it is within factory specifications. Deviations may indicate problems with the turbochargers or intake system.

Installing a Pressure Gauge: Consider installing an additional pressure gauge to monitor the boost pressure, especially if you plan to tune the engine.
