Technical characteristics of Nissan Sunny B12 1986

Model range Sunny B12 1986 included several modifications, differing in body types, drivetrains and power units. Basic versions were equipped with carburetor engines of the series E15/E16, and the top ones are injection GA15i/GA16i. Particularly interesting is the version with all-wheel drive (4WD), which was supplied to the USSR in limited quantities.

Main technical parameters:

Parameter E15S (carb.) GA15i (eng.) GA16i (eng.) CA16DE (turbo)
Volume, cm³ 1 488 1 497 1 597 1 597
Power, hp 75 90 100 125
Gearbox 4 manual transmission / 3 automatic transmission 5 manual transmission / 4 automatic transmission 5 manual transmission / 4 automatic transmission 5 manual transmission
Drive FWD / 4WD FWD / 4WD FWD FWD
Max. speed, km/h 155 170 180 200

The turbocharged version deserves special attention CA16DE, which was installed on sports modifications Sunny GTi-R (although it was not yet released in 1986, prototypes were being tested). Standard versions with engines GA16i could accelerate to 180 km/h, which was an excellent indicator for a compact sedan of those years.

The transmission on most models is a 5-speed manual, but there are also automatic transmissions (3 or 4 steps). All-wheel drive versions (4WD) were equipped with a transfer case with a reduction gear, which made them universal for off-road use.

Weaknesses and typical problems

Despite the legendary reliability, Nissan Sunny B12 has a number of “diseases” that every owner should know about. Most problems are related to age of the car and quality of service. Let's look at the key components that require attention.

1. Body corrosion. The main headache for owners is rust. Particularly vulnerable:

  • 🚗Sills and wheel arches (rot from the inside)
  • 🚪 Bottoms of doors (moisture accumulation)
  • 🔧 Trunk lid (at the places where the seal is attached)
  • 🚙 Spars (safety critical)

2. Engine and power system:

  • 🔥 Carburetors Hitachi or Solex require regular cleaning (especially jets)
  • ⚡ Problems with the distributor (bearing wear, shaft play)
  • 🛢️ Oil leaks through crankshaft seals (typical for engines with mileage >200 thousand km)
  • 🔋 Generator malfunctions (the diode bridge often fails)

3. Transmission and chassis:

  • 🔄 Wear of 2nd and 3rd gear synchronizers in manual transmission
  • 🛞 Play in ball joints and steering rods
  • 🔧 Leaking drive shaft seals (especially on all-wheel drive versions)
  • 🚗 Knocks in the rear suspension (wear of the torque rod bushings)
⚠️ Attention: On all-wheel drive Sunny B12 The transfer case often fails due to lack of oil. Check the level every 10,000 km - this will extend the life of the unit.

Electrics also require attention: oxidation of contacts in the fuse box, burnt-out ignition relay, problems with the temperature sensor. It is especially difficult to diagnose faults in systems with electronic ignition (versions with injector).

💡

Before purchasing Nissan Sunny B12 Be sure to check the condition of the side members with an endoscope - rust may not be visible on the outside, but inside the metal is often eaten right through.

Maintenance and repair: what you need to know

Service Nissan Sunny 1986 has its own characteristics. The main rule is regularity. Due to the age of the car, even minor maintenance omissions can lead to serious damage. Let's look at the key points.

1. Changing oil and filters:

  • 🛢️ Motor oil: 10W-40 (semi-synthetic) or 15W-40 (mineral water for old engines)
  • 🔧 Oil filter: original Nissan 15208-65F00 or analogues Mann W67/1, Framm PH2866
  • ⚙️ Air filter: change every 15,000 km (more often on carburetor versions)
  • ⛽ Fuel filter: on injection models - every 30,000 km

2. Adjustments and settings:

  • 🔧 Valve clearances: check every 20,000 km (norm: 0.20 mm inlet, 0.30 mm release)
  • ⚡ Ignition timing: 10°±2° (for carburetor versions)
  • 🎯 Wheel alignment: check after any suspension repair
  • 🔋 Timing belt tension: critical for engines GA16i (a break leads to bending of the valves)

3. Brake system:

  • 🚗 Brake pads: front - every 30,000 km, rear - 50,000 km
  • 🛢️ Brake fluid: replace once every 2 years (regardless of mileage)
  • 🔧 Brake cylinders: check for leaks and piston play
  • 🔄 Bleeding the brakes: mandatory after any intervention in the system

Change the oil to winter oil (5W-30 or 5W-40)|

Check the condition of the battery (capacity and electrolyte level)|

Lubricate all rubber seals with silicone grease|

Check the operation of the stove and thermostat|

Inflate tires to recommended pressure (2.0-2.2 bar)|

Tuning and modernization

Often owners Nissan Sunny B12 want to improve its performance or appearance. Tuning can be divided into several areas: engine, suspension, exterior And interior. Let's look at the most popular and rational modifications.

1. Increase engine power:

  • 🔥 Installation sports camshaft (for example, from Nissan Pulsar GTi-R)
  • ⚡ Reflashing the ECU (for injection versions, requires setup on a bench)
  • 🛢️ Installation straight-through exhaust (for example, systems 4-2-1)
  • 🔋 Replacing the carburetor with an injector (requires a complete rework of the power system)

2. Suspension upgrade:

  • 🚗 Installation low profile rubber (For example, 195/50 R15)
  • 🛞 Replacing shock absorbers with gas-oil ones (for example, KYB Excel-G)
  • 🔧 Installation reinforced anti-roll bars
  • 🔄 Springs H&R or Eibach to reduce clearance

3. External and internal tuning:

  • 🎨 Full painting with corrosion protection (for example, processing ML-mastic)
  • 🚪 Installation sports bumpers (from Nissan Pulsar or Sunny GTi)
  • 💺 Replacing seats with forged (for example, from Recaro)
  • 🔊 Installation of a modern radio with support Bluetooth And USB
⚠️ Attention: When tuning the engine E15S (carburetor) it is not recommended to increase power by more than 20% — the cylinder block is not designed for high loads and may crack.

One of the most popular areas of tuning is the installation all-wheel drive for front-wheel drive versions. This requires replacing the rear beam, driveshaft, transfer case and rear axle gearbox. This modification is expensive, but makes the car truly versatile.

How to check the authenticity of the GA16i engine?

Original engine GA16i has the following distinctive features:

1. The engine number is stamped on the block on the right (flywheel side) and starts with GA16.

2. The cylinder head has 16 valves (as opposed to 8 valve versions E16).

3. There is an inscription on the valve cover Nissan GA16i or GA16DE (for turbo versions).

4. The intake manifold of injection versions has an absolute pressure sensor (MAP-sensor).

If any of these signs are missing, there is a good chance that the engine has been replaced or undergone major repairs.

Search for spare parts: where to buy and what to look for

The main problem of the owners Nissan Sunny B12 — shortage of original spare parts. Many parts are no longer produced, but there are several proven ways to find them:
