Nissan Sunny B12 - the legendary Japanese sedan, which became a symbol of reliability and practicality of the 80s. This model, produced from 1985 to 1990, is still in demand among collectors and retro car enthusiasts. But before buying, it is important to understand its features: from engines to typical “diseases”. This article contains a complete analysis technical characteristics, weak points And tuning optionsthat will help you make an informed choice.
B12 became a logical continuation of the line Sunny, offering customers improved aerodynamics, more modern design and new power units. The car was produced in sedan, hatchback and station wagon bodies, which expanded its target audience. Today original copies with mileage less than 100 thousand km are considered a rarity and are valued at 2-3 times more expensive than “tired” versions. But even worn out Sunny B12 you can bring it back to life - the main thing is to know what to pay attention to.
Technical characteristics of Nissan Sunny B12
The model was offered with three types of engines, each of which had its own characteristics. Basic 1.3-liter carburetor unit E13 developed 69 hp and was considered the most reliable, but low-power. Was more popular 1.6 liter E16 (86 hp), which combined reasonable fuel consumption (7-9 l/100 km) and acceptable dynamics. The top version was equipped 1.8 liter CA18 with fuel injection producing 103 hp. — this engine was inherited by sports modifications Sunny GTi-R.
Transmissions were offered to choose from: 4- or 5-speed manual, as well as a 3-band automatic. Suspension - classic for that time: front MacPherson, at the rear there is a semi-independent beam. The brake system is combined: discs at the front and drums at the rear (on basic versions). The maximum speed varied from 150 to 180 km/h depending on the engine.
- 🔧 Engines: E13 (1.3), E16 (1.6), CA18 (1.8)
- ⚡ Power: 69–103 hp
- 🔄 Boxes: Manual transmission-4, manual transmission-5, automatic transmission-3
- 🛣️ Drive: front or full (4WD)
| Modification | Volume, l | Power, hp | Consumption (city), l/100 km | Max. speed, km/h |
|---|---|---|---|---|
| E13 (carburetor) | 1.3 | 69 | 8.5 | 150 |
| E16 (carburetor) | 1.6 | 86 | 9.2 | 165 |
| CA18i (injector) | 1.8 | 103 | 9.8 | 180 |
| CA18ET (turbo) | 1.8 | 130 | 11.0 | 195 |
⚠️ Attention: Modifications with engine CA18ET (turbo) require special attention to the cooling system. Overheating of this engine often leads to deformation of the cylinder head.
Typical problems and weaknesses
Despite the reputation of an "indestructible" car, Sunny B12 has a number of characteristic disadvantages. The main headache for owners is body corrosion. Particularly vulnerable are the sills, wheel arches and lower parts of the doors. If traces of rust are already visible in these areas, most likely the metal is rotten through and through. The second most common defect is suspension wear: silent blocks, ball joints and shock absorbers rarely “live” to 100 thousand km.
In engines E13/E16 often fails carburetor — it has to be cleaned or replaced every 50–60 thousand km. For injection versions CA18 weak point is fuel pump and sensors (especially the throttle position sensor). Electrics are also not reliable: contacts oxidize, fuses blow, and the generator can fail without warning.
- 🚗 Body: rust on the sills, arches, bottom
- 🔩 Suspension: wear of silent blocks, balls, shock absorbers
- ⛽ Engine: problems with carburetor (E13/E16), fuel pump (CA18)
- ⚡ Electrical: contact oxidation, generator failure
- 1.3 (E13)
- 1.6 (E16)
- 1.8 (CA18)

Another common problem is seal leakage. This happens especially often with the rear crankshaft oil seal, which leads to oil getting into the clutch. If you notice oil stains under the car, check the oil level and condition of the seals. It is also worth paying attention to gearbox: In manual transmissions, synchronizers wear out over time, and automatic transmissions suffer from wear on the clutches.
⚠️ Attention: Upon purchase Sunny B12 With automatic transmission, be sure to check the oil in the box. If it is black or has a burning smell, get ready for a major overhaul.
Repair and maintenance: what to pay attention to
Service Nissan Sunny B12 does not require special skills, but there are nuances. For example, changing engine oil should be carried out every 5–7 thousand km (even if the previous owner claimed that he used “synthetics”). For carburetor engines, mineral or semi-synthetic oil with a viscosity of 10W-40, and for injection CA18 better use 5W-30 or 5W-40.
When replacing timing belt on engines E16 And CA18 be sure to check the condition of the pump - its service life rarely exceeds 80 thousand km. If the pump begins to “leak” or make strange sounds, it needs to be replaced urgently. Otherwise, the risk of the timing belt breaking and the valves meeting the pistons increases significantly. Also don't forget about valve adjustment - on these engines it is required every 20-30 thousand km.
Check the body for rust (especially sills and arches)|
Start the engine when cold - there should be no knocking or vibrations |
Make sure all electrical equipment works (lights, windows, heater)|
Check the oil in the gearbox and axle (if the drive is 4WD)|
Assess the condition of the suspension - there should be no play or extraneous sounds -->
If your Sunny equipped all-wheel drive (4WD), pay special attention to the transfer case and rear axle. The oil in them needs to be changed every 40 thousand km, and the seals - at the first sign of a leak. Also check the condition of the cardan shafts and crosspieces. In winter, all-wheel drive versions require more frequent maintenance, as salt and reagents accelerate corrosion of transmission elements.
When purchasing spare parts for Sunny B12, pay attention to the catalog numbers. Many parts from the B11 (previous generation) do not fit, despite the external similarity.
Tuning and modernization
Thanks to its simple design, Sunny B12 lends itself well to tuning. The most popular destinations are power increase, improved handling And exterior restyling. For engines E16 And CA18 Sports camshafts, direct-flow exhaust systems and tuning chip boxes are available. Turbocharged CA18ET you can boost it to 160–180 hp, but this will require a reinforced gearbox and clutch.
In terms of suspension, many owners install sports shock absorbers (For example, KYB or Tokico), springs lowered by 30–50 mm and reinforced anti-roll bars. To improve braking performance, ventilated discs from Nissan Pulsar or Silvia. External tuning is usually limited to installing body kits, spoilers and alloy wheels 14–15 inches.
- 🔥 Engine: sports camshafts, direct-flow exhaust, chip tuning
- 🚗 Suspension: lowering, reinforced shock absorbers, polyurethane silent blocks
- 🛡️ Brakes: ventilated discs, sports pads
- 🎨 Exterior: body kits, spoilers, tinting, LED optics
How to increase the power of CA18 without a turbine?
Install sports camshafts with 264/264 timing, 4-2-1 direct-flow exhaust, cold air intake and a tuning chip. This will allow you to remove an additional 15–20 hp. without major modifications to the cylinder block.
Popular for lovers of retro style interior restoration: upholstery of seats in leather or Alcantara, installation of a sports steering wheel Nardi or Momo, replacing the standard radio with a modern one with support Apple CarPlay. Some enthusiasts install a digital instrument panel from Nissan 300ZX, but this requires serious modification of the electrical wiring.
Cost and where to buy
Prices for Nissan Sunny B12 vary greatly depending on condition, mileage and rarity of modification. "Tired" copies with a mileage of over 200 thousand km can be found for 80–150 thousand rubles, but their restoration will cost another 100–200 thousand. More well-maintained cars with mileage up to 100 thousand km cost 250–400 thousand rubles. Rare versions such as Sunny GTi-R or all-wheel drive 4WD, can reach 600–800 thousand rubles.
Where to look:
- 🌍 Avito/Drom: the largest selection, but many “killed” copies
- 🏆 Retro car clubs: well-maintained cars with history are often sold
- 🇯🇵 Japanese auctions: you can find original copies, but with delivery the price will increase by 30–50%
- 🔧 Service station for Japanese cars: sometimes workshops sell restored cars
Be sure to check when purchasing car history: presence of an accident, replacement of body panels, condition of the engine and gearbox. If the seller refuses to provide the car for lifting, this is a reason to be wary. It is also worth checking the car through services Autocode or CarVerticalto ensure there are no restrictions or collateral.
⚠️ Attention: Upon purchase Sunny B12 with a mileage of more than 150 thousand km, be prepared to replace all rubber seals (oil seals, boots, pipes). After 30+ years, rubber loses its elasticity and begins to crack.
Alternatives and analogues
If Nissan Sunny B12 seemed too rare or expensive to repair, consider analogues of that period:
- 🚗 Toyota Corolla E80: more reliable, but less dynamic
- 🚗 Honda Civic 3/4 generation: better handling, but more difficult to repair
- 🚗 Mazda Familia BG: similar dimensions, but more modern suspension
- 🚗 Mitsubishi Lancer A170: cheaper to maintain, but less comfortable
