We focus on what really matters to owners Terrano R20 with a diesel engine - from the nuances of the fuel system to the features of the transmission and suspension.
Technical characteristics of Nissan Terrano 1993 diesel
Under the hood Nissan Terrano 1993 with a diesel engine a naturally aspirated engine was installed TD27 volume 2.7 liters. This engine, developed back in the 1980s, was famous for its simplicity and reliability, but it also had a number of features that are worth knowing about.
Basic version developed 95 hp at 4200 rpm and torque 205 Nm at 2000 rpm. The engine was paired with a 5-speed manual transmission, and in some modifications - a 4-speed automatic. The drive could be either rear-wheel drive or all-wheel drive (4WD), with the possibility of connecting the front axle.
- 🔧 Engine: TD27 (2.7 l, 95 hp, naturally aspirated)
- ⚙️ Gearbox: Manual transmission-5 or automatic transmission-4
- 🚗 Drive: rear or full (
4WD) - 💨 Maximum speed: 145 km/h (with manual transmission)
- ⛽ Fuel consumption: 9-11 l/100 km (depending on conditions)
Feature TD27 was its design with one-piece cylinder block and a cast iron head. This made the engine heavy (about 220 kg), but at the same time extremely resistant to overheating. However, due to the lack of turbocharging, the acceleration dynamics left much to be desired - the car accelerated to 100 km/h in 20-22 seconds.

Weaknesses and typical malfunctions
Despite the legendary reliability, Nissan Terrano 1993 with a diesel engine had several vulnerabilities. One of the most common problems was fuel tank corrosion. Due to the poor quality of the metal and the lack of anti-corrosion treatment, the tanks often rusted from the inside, which led to clogging of the fuel system.
Another "disease" - camshaft wear and pushers. With a mileage of over 200,000 km, a characteristic knocking sound often appeared, which over time developed into a serious problem. It is also worth paying attention to:
- 🔥 Fuel injection pump (high pressure fuel pump): wear of plunger pairs after 150,000 km
- 🔗 Timing chain: stretching after 100,000 km (requires replacement)
- 💧 Cooling system: radiator and pump leaks
- 🔩 Suspension: wear of silent blocks and ball joints
⚠️ Attention: If the engine TD27 started to "trouble" at idle speed, check the condition injectors And air filter. Often the problem lies in a clogged air supply system.
Deserves special attention electrical wiring. Over time, the insulation of the wires becomes brittle, leading to short circuits. The wires going to the temperature sensor and fuel pump are especially vulnerable.
Maintenance and repair: what the owner needs to know
Operation Nissan Terrano 1993 with a diesel engine requires regular maintenance. Here are the key points to pay attention to:
- Oil change: every 7,000–10,000 km (use oil with a viscosity
15W-40for diesel engines). - Filters: Change the fuel filter every 20,000 km, the air filter every 15,000 km.
- Valve adjustment: every 40,000 km (intake valve clearance -
0.25 mm, graduations -0.30 mm). - Checking the timing chain: every 50,000 km for stretching.
During repairs injection pump It is recommended to use original spare parts or analogues from Bosch. Cheap Chinese components often fail after 10,000–15,000 km. Also pay attention to the condition fuel lines - Over time, they can crack and leak air, which leads to problems with starting the engine.
Change the oil to winter oil (5W-40)
Check the battery condition
Add antigel additive to fuel
Check the operation of the glow plugs
Clean the injectors from deposits -->
If you are planning engine overhaul, please note that the cylinder block TD27 cannot be bored to repair dimensions. If there is severe wear, the sleeves or the block itself will need to be replaced.
Tuning and modernization: how to improve Nissan Terrano 1993
Many owners Nissan Terrano strive to modernize their cars. The most popular tuning areas:
- 🚀 Turbine installation: you can adapt the turbo kit from TD27T (replacement of pistons and connecting rods will be required).
- 🔋 Fuel system upgrade: replacing injectors with more efficient ones (for example, from Isuzu 4JG2).
- 🛡️ Suspension reinforcement: installation of springs and shock absorbers from Nissan Patrol to increase cross-country ability.
- 🔌 Electronics: replacing standard wiring with a more reliable one, installing a modern ECU.
One of the most effective ways to improve dynamics is chip tuning. Reflashing the control unit allows you to increase power by 15–20 hp. without major modifications. However, before doing this, you need to make sure that injection pump And turbines (if installed).
What does installing an intercooler do?
Installing an intercooler allows you to reduce the charge air temperature by 20–30°, which increases air density and improves cylinder filling. As a result, engine power can increase by 10–15 hp, and fuel consumption will decrease by 0.5–1 l/100 km.
When tuning transmissions, they often install differential lock (for example, from ARB), which significantly improves off-road performance. It is also popular to replace the standard transfer case with a model with a reduction gear.
Search for spare parts: where and what to buy
The main problem of the owners Nissan Terrano 1993 — shortage of original spare parts. However, many parts are interchangeable with other models Nissan And Isuzu. For example:
| Detail | Analogue (model) | Note |
|---|---|---|
| injection pump | Isuzu 4JB1, Mitsubishi 4D56 | Requires modification of fastenings |
| Clutch | Nissan Patrol Y60 | Full compatibility |
| Wheel bearings | Toyota Land Cruiser 80 | Fits front and rear |
| Radiator | Nissan Navara D22 | Requires adjustment to fasteners |
When purchasing spare parts, pay attention to catalog numbers. For example, the original fuel filter for TD27 has a number 16400-4M500, but an analogue from Mann (WK 820/2). To find rare parts, it is recommended to use Japanese auctions or specialized forums such as Club-Terrano.ru.
⚠️ Attention: When purchasing used spare parts from disassembly sites, be sure to check them for hidden defects. For example, used cylinder heads often have microcracks that are difficult to detect without special equipment.
If you are looking for parts for transmissions, pay attention to handouts from Nissan Pathfinder R50 — they fit without modifications. Gearboxes from Nissan Hardbody (model FS5R30A).
Operation in winter conditions: tips and life hacks
Winter operation Nissan Terrano with a diesel engine has its own nuances. The main problem is fuel freezing. To avoid this, use winter diesel fuel with additives or add antigel (For example, Liqui Moly Diesel Fliess-Fit).
Pay special attention preheating system. If your Terrano not equipped Webasto, you can install an electric heater (Defa or Eberspacher). Also recommended:
- ❄️ Check the glow plugs: their resistance should be within
0.5–6 Ohm. - 🔋 Charge the battery: the capacity must be at least
75 Ah. - 🛢️ Change oil: use synthetics with viscosity
5W-40. - 🚪 Lubricate the door seals: this will prevent them from freezing.
Critical: If the engine does not start at temperatures below -20°C, do not attempt to crank it for more than 10 seconds at a time. This may result in battery drain or damage to the bendix. Instead, use the "smoking" method or a preheater.
If the engine still does not start, try pouring 10–15 ml of kerosene into the air filter (through the pipe). This will temporarily make starting easier, but do not overuse the method - kerosene is aggressive to rubber seals.
