Nissan Sunny B12 1985 is not just a car, but an entire era in the history of the Japanese automobile industry. The compact sedan, which has gained popularity due to its reliability, efficiency and unpretentiousness, is still in demand among connoisseurs of retro cars and practical drivers. In this article we will look at everything you need to know about Second generation Sunny in the back of B12: from technical features to the nuances of repair and tuning.
Released at the height of the 80s, when Japanese manufacturers were actively exploring world markets, Sunny B12 has become a symbol of accessibility and quality. Its ease of maintenance, cheap spare parts and durable engines made the model an ideal choice for those looking for a reliable car with history. But even such legends have weaknesses - we will also tell you about them.
Technical specifications Nissan Sunny B12 1985
Under the hood Sunny B12 1985, two main types of engines were installed: gasoline E15 (1.5 l) and E16 (1.6 l). Both units belonged to the series Nissan E, known for its unpretentiousness and resource. Power varied from 75 hp to 90 hp depending on modification and market. Transmissions were offered as either manual (4- or 5-speed) or automatic (3-speed).
Drive Sunny B12 was exclusively front-wheel drive - this was an innovative solution for the time when many competitors were still producing rear-wheel drive models. Front independent suspension (type MacPherson), at the rear there is a semi-independent beam. The brake system is combined: front discs and rear drums. The body was produced in several versions: sedan, hatchback and station wagon (in some countries known as Nissan Pulsar).
- 🔧 Engines: E15 (1.5 l, 75–80 hp), E16 (1.6 l, 85–90 hp)
- ⚙️ Gearboxes: Manual transmission-4, manual transmission-5, automatic transmission-3
- 🚗 Body: sedan (B12), hatchback (N12), station wagon (VB12)
- ⛽ Fuel consumption: 7–9 l/100 km (city), 5–6 l/100 km (highway)
| Parameter | E15 (1.5 l) | E16 (1.6 l) |
|---|---|---|
| Power, hp | 75–80 | 85–90 |
| Torque, Nm | 112–118 | 125–130 |
| Max. speed, km/h | 160–165 | 170–175 |
| Acceleration 0–100 km/h, s | 13–14 | 11–12 |
Feature of the model: in some markets (for example, in Europe) the Sunny B12 was equipped with a fuel injection system instead of a carburetor, which improved dynamics and efficiency. However, carburetor versions are still easier to repair and cheaper to maintain.
Weaknesses and typical malfunctions
Despite the legendary reliability, Nissan Sunny B12 has a number of “diseases” that you should know about before purchasing. The main problem is body corrosion. The sills, wheel arches and underbody are especially vulnerable. If the car has not been treated with anticorrosive, rust can completely “eat” the metal in 10–15 years. The second weak point is rubber seals: Over time, they become tanned and begin to let water into the interior.
In series engines E Most often they fail:
- 🔥 Cylinder head gasket - if it overheats, it can “lead”, which leads to mixing of oil and antifreeze.
- 🛢️ Oil pump - gear wear leads to a drop in oil pressure, especially on engines with mileage over
200,000 km. - ⚡ Ignition system — coils and distributors require regular checking.
⚠️ Attention: If you hear a metallic knock when starting the engine, this may be a sign of wear on the main or connecting rod bearings. In this case, operating the car without repair is fraught with engine jamming.
Transmission Sunny B12 usually lasts a long time, but automatic transmission (if there is one) may begin to “kick” when running for 150,000 km. Most often, worn clutches or solenoids are to blame. In manual transmissions the weak point is input shaft bearing — its hum can easily be confused with the noise of the clutch.

Repair and maintenance: what the owner needs to know
Service Nissan Sunny B12 does not require special skills, but there are nuances that will help save time and money. For example, changing engine oil should be carried out every 5,000–7,000 km, if mineral or semi-synthetic oil is used. For motors E15/E16 Suitable oil viscosity 10W-40 or 15W-40 (depending on climate).
Particular attention should be paid cooling system. It is recommended to change antifreeze once every 2 years, and check the thermostat at the first sign of overheating. If the engine temperature rises above 100°C, this may indicate:
- 🔥 Clogged radiator
- 💦 Faulty cooling fan
- 🚰 Air lock in the system
☑️ Maintenance of Nissan Sunny B12 before winter
The braking system also requires regular monitoring. Rear wheel drum brakes are prone to souring, so they need to be cleaned and the guides lubricated every 30,000–40,000 km. Front brake discs last longer, but they should be replaced if they develop runout or deep grooves.
⚠️ Attention: If the pedal becomes soft after replacing the brake pads, this may indicate air entering the system. In this case, bleeding of the brakes is required.
Tuning and modernization: how to improve Sunny B12
Despite his venerable age, Nissan Sunny B12 has great potential for tuning. Most popular destinations:
- 🚀 Power increase — installation of a turbine (for example, from Nissan SR20), sports camshafts or chip tuning (for injection versions).
- 🎨 External tuning — body kits, spoilers, tinting and replacement of optics with LED ones.
- 🛞 Suspension and wheels — installation of lowered springs and shock absorbers KYB or Tokico, as well as alloy wheels
R14–R15. - 🔊 Audio system — replacement of the standard radio with a modern one with support Bluetooth and installation of a subwoofer.
One of the most effective ways to improve dynamics is replacing the carburetor with an injector. For this purpose, kits from Nissan GA16DE or SR20DE. However, such tuning requires modification of the electrical wiring and installation of a new ECU. A more budget-friendly option is installation sports camshaft (for example, from Nissan B13) and direct-flow exhaust.
What engine can be swapped in the Sunny B12?
The most popular swap options for Nissan Sunny B12:
- SR20DE (2.0 l, 150+ hp) - requires modification of pallets and fastenings.
- CA18DET (1.8 l, turbo, 170+ hp) — the gearbox and attachment need to be replaced.
- GA16DE (1.6 l, 105 hp) - easier to install, but less powerful.
- KA24E (2.4 l, 140 hp) - reliable, but heavy for the B12 body.
Any swap will require modifications to the wiring, fuel system, and possibly engine mount.
External tuning often begins with installation body kits from Nismo (if you find original ones) or universal kits. Also popular restyled bumpers from later versions B13. To improve handling, many install anti-roll bars and reinforced silent blocks.
Where to buy spare parts and how much they cost
One of the main advantages Nissan Sunny B12 is the availability of spare parts. Most parts are interchangeable with other models Nissan 80–90s, such as Pulsar N13, Sentra B13 and even Almera N15. Main sources of spare parts:

FAQ: Frequently asked questions about Nissan Sunny B12
Which engine is better: E15 or E16?
E16 (1.6 l) more powerful and dynamic, but E15 (1.5 l) more economical and easier to repair. If reliability and low fuel consumption are important to you, choose E15. Better for tuning or driving on the highway E16.
Is it possible to put diesel in Sunny B12?
Theoretically yes, but it is a complex and expensive project. Most often, diesel engines are swapped from Nissan LD20 (2.0 l), but will require replacement of the gearbox, fuel system and modification of the fasteners. This is not economically feasible - it’s easier to buy Sunny with a gasoline engine.
What kind of oil to pour into an E16 engine?
For E16 semi-synthetic oil is suitable 10W-40 or 15W-40 (For example, Lukoil Lux, Castrol GTX). If the engine is worn out (mileage > 200,000 km), it is better to use oil with high viscosity, for example, 20W-50.
How to deal with rust on thresholds?
The only effective way is cutting out rusty areas and welding new inserts. Cosmetic repairs (putty, anticorrosive) will give a temporary effect. For prevention, treat thresholds Movilem or Tektile every 2 years.
Where can I find a wiring diagram for Sunny B12?
Official diagrams can be downloaded from the forums (Nissan-Club.ru, Drive2.ru) or buy a paper repair manual (for example, Haynes Manual for Nissan Sentra B12). Resources like Nicoclub.com (section FSM — Factory Service Manuals).
