Installed inside forged crankshaft with piston stroke 103 mm, and also steel connecting rods with bronze liners. The pistons are made of aluminum alloy with oil scraper rings improved design.

2. Cylinder head (cylinder head)

The cylinder head is made of aluminum and equipped two camshafts (DOHC) with 16 valves. A special feature is the presence hydraulic compensators, which eliminate the need to adjust the gaps. However, over time, they may begin to “knock”, which requires replacement.

3. Common Rail injection system

The fuel system was developed by the company Denso and works under pressure up to 1600 bar. It includes:

• 🔋 Fuel injection pump (high pressure fuel pump) with electronic control;
• 💉 Injectors with 6-hole nozzles;
• 🖥️ ECU (electronic control unit), which adjusts the fuel supply depending on the load.

4. Turbocharging and intercooler

Most versions had a turbine installed Garrett GT2056V with variable geometry (VGT), which provides good traction already with 1200 rpm. To cool the charge air it is used air-to-air intercooler, located in front of the radiator.

One of the weaknesses of the system is EGR valve clogged, which over time becomes covered with soot and requires cleaning or jamming. It can also wear out at high mileage. turbine vacuum drive, which leads to loss of power.

Typical problems and malfunctions of DTR 35

Despite its high reliability, the engine Nissan DTR 35 has several “diseases” that manifest themselves at high mileage. Knowing these problems will help you avoid costly repairs.

1. Problems with the turbine

The most common malfunction is turbine bearing wear, which appears as:

• 🔊 Whistling or howling when picking up speed;
• 💨 Power loss and black smoke from the exhaust pipe;
• 🛢️ Increased oil consumption (due to leakage through the turbine).

The reasons are often contaminated oil or untimely replacement of the oil filter. Average turbine resource - 150–200 thousand km, but with careful use it can last longer.

2. Fuel system malfunctions

System common rail sensitive to fuel quality. Typical problems:

• 🔧 Clogged injectors (leads to uneven operation of the cylinders);
• 💧 Wear of fuel injection pump (manifested by difficulties with starting);
• ⚡ Open injector power supply circuit (a common problem on runs beyond 300 thousand km).

For prevention it is recommended to use only high-quality diesel fuel and every 60–80 thousand km flush the fuel system.

3. Problems with EGR and particulate filter

Valve EGR (exhaust gas recirculation system) Over time it becomes clogged with carbon deposits, which leads to:

• 🔥 Engine overheating;
• 🚗 Jerking when moving;
• 💨 Increased fuel consumption.

Many owners prefer turn off EGR or install decoy, but this requires flashing the ECU. Particulate filter (DPF) can also become clogged, especially during urban use.

4. Oil and antifreeze leaks

On runs for 200 thousand km Leaks often appear:

• 🛢️ From under the valve cover (gasket wear);
• 🔥 From under the thermostat;
• 🚰 From the radiator or pipes.

Regular inspection and replacement of gaskets will help avoid serious problems.

What happens if you ignore a turbine malfunction?

If the turbine malfunction is not corrected in time, this can lead to:

1. **Oil getting into the intercooler and intake manifold**, which will cause the valves to become oily and reduce compression.

2. **Destruction of turbine bearings** and metal shavings entering the engine, which will require major repairs.

3. **Engine overheating** due to a lack of air supply, which can cause cylinder head deformation.

Maintenance and routine maintenance

Timely maintenance is the key to long engine life Nissan DTR 35. Below is maintenance regulations taking into account difficult operating conditions (for example, off-road driving or in hot climates).

Type of work	Frequency (thousand km)	Notes
Changing the oil and oil filter	7–10	Oil recommended 5W-40 or 10W-40 with permission API CF-4.
Replacing the air filter	20–30	In dusty conditions (desert, off-road) - every 10–15 thousand km.
Replacing the fuel filter	20–25	Critical to the longevity of the injection pump and injectors.
Checking and replacing the timing belt	100–120	If the valve belt breaks doesn't bend, but it's not worth the risk.
Cleaning the EGR valve	50–60	In case of heavy contamination, damping is recommended.

Particular attention should be paid cooling system. It is recommended to change antifreeze every 60–80 thousand km, and also regularly check the condition of the pipes and radiator. In hot climates (for example, in the UAE or Saudi Arabia), it is better to update the coolant more often - every 40–50 thousand km.

Also don't forget about compression check (norm - 28–32 bar in each cylinder) and turbine diagnostics when the first signs of trouble appear. Timely maintenance allows you to extend the engine life up to 500 thousand km and more.

🔹 Check oil and coolant levels

🔹 Inspect the pipes for cracks and leaks

🔹 Diagnose the turbine for play

🔹 Clean the air filter (or replace)

🔹 Check the operation of the EGR valve (clean if necessary)

• 🚀 Up to 220–240 hp (Stage 1, without mechanical modifications);
• 💪 Up to 260–280 hp (Stage 2, with reinforced injection pump and injectors);
• 🔥 More than 300 hp (Stage 3, with replacement of the turbine and intercooler).

However, it is worth remembering that increasing power leads to increased load on the gearbox and transmission, so the clutch and transfer case may need to be strengthened.

2. Installing a larger turbine

Standard turbine Garrett GT2056V limits engine potential. For serious tuning install:

• 🌀 GT2260V (improved version with variable geometry);
• 💨 GT2560 (for high speeds, but with more noticeable turbo lag);
• 🔥 Hybrid turbines (for example, from BorgWarner).

When replacing a turbine, it is necessary exhaust system modification (removing the catalyst, installing direct flow) and setting up a fuel map.

3. Strengthening the fuel system

For power over 250 hp standard injectors and injection pumps become a bottleneck. In such cases, set:

• 💉 Injectors from Denso or Bosch with increased productivity;
• 🔋 Injection pump with a reinforced plunger mechanism;
• 🛢️ Additional low pressure fuel pump.

4. Off-road modifications

The following improvements are relevant for off-road enthusiasts:

• 🏜️ Installation of crankcase and transmission protection;
• 🚗 Modernization of the cooling system (additional radiator);
• 🔧 Replacing a standard intercooler with a more efficient one (for example, from PWR).

⚠️ Attention: When tuning DTR 35 higher 250 hp Reinforcement of the gearbox (especially automatic) and transfer case is required. Otherwise, the risk of transmission failure increases several times.

💡

Before tuning, be sure to check the condition of the engine! If the compression in the cylinders is lower 28 bar or there is play in the turbine, first carry out a major overhaul. Increasing power on a worn-out engine will lead to its rapid failure.
