The version stands apart Turbo Medalist with motor CA18ET — it was equipped with an intercooler, reinforced brakes and a sports suspension. Automatic boxes 4N71B on turbo versions they often fail during aggressive driving, so mechanics are considered preferable.

Weaknesses and typical problems

Despite the reputation of a reliable car, Laurel 1986 has several “diseases” that every buyer should know about:

• 🔧 Body corrosion: Particularly vulnerable are the sills, rear wheel arches and the bottom under the trunk. Check the condition of the metal using thickness gauge — rust is often hidden under a layer of putty.
• 🔥 Engine overheating: On CA18ET Most often the thermostat or radiator fails. Monitor the antifreeze level and the condition of the pipes.
• ⚙️ Automatic transmission: automatic transmission 4N71B afraid of overheating and requires regular oil changes (every 40,000 km). If there is any slipping or jerking when switching, get ready for a major overhaul.
• 💡 Electrics: Oxidation of contacts in the fuse box and alternator malfunctions are common problems. Check the operation of all instruments on the panel.

⚠️ Attention: If during inspection you find oil in the coolant expansion tank, this is a sign broken cylinder head gasket. On CA18ET such a malfunction often leads to antifreeze entering the cylinders and causing water hammer.

One more nuance - suspension. Silent blocks of levers and stabilizer bushings wear out to 100,000 km, and the shock absorbers leak after 80,000 km. When purchasing, be sure to check the play in the steering and the condition of the ball joints.

How to choose a Nissan Laurel 1986: buyer's checklist

Upon examination Laurel C31 Please pay attention to the following points:

Originality of the body (check the VIN with the plate on the dashboard)

Condition of sills and arches (tap with a hammer)

Turbine operation (at CA18ET there should be no oil smoke from the exhaust)

Automatic transmission oil level (should be red, without a burning smell)

Integrity of electrical wiring (check all lamps and devices)

-->

Pay special attention documentation. Japanese cars were often imported to Russia through USS auctions or TSK, so check the history by VIN on sites like CarVertical. If the vehicle title indicates mileage less than 50,000 km, but the condition of the interior and body indicates the opposite - most likely, the odometer is “twisted”.

Prices for Laurel 1986 in Russia vary from 200,000 to 600,000 rubles, depending on condition and configuration. Turbo versions with mechanics cost 30–50% more expensive atmospheric. Instances with mileage up to 100,000 km in original condition - very rare and usually sold to collectors.

Tuning and modifications: what can be done with Laurel C31

Thanks to its simple design and availability of spare parts, Laurel 1986 - an excellent base for tuning. Here are some popular destinations:

• 🚀 Power increase: On CA18ET turbine is often installed Garrett T25, larger intercooler and ECU chip tuning. This allows you to increase power up to 180–200 hp without major modifications to the block.
• 🎨 External tuning: Installation of body kits from Nissan Silvia S12, LED optics and xenon headlights. Wide tires are also popular (up to 225/50 R15) and alloy wheels Work Equip.
• 🔊 Audio system: A subwoofer can be easily placed in the cabin, and the acoustics in the doors are replaced with component ones (for example, Pioneer TS-A1676F).
• 🛠️ Suspension: Installation of springs Tein or Tanabe and shock absorbers KYB improves handling. Differential locking is often used for drifting. Nismo.

What happens if you install a turbine from a Silvia S13 on a CA18ET?

It is possible, but you will need to replace the manifold, intercooler and adjust the fuel system. Standard turbine T25 from Silvia S13 produces more pressure, so it is necessary to strengthen the piston group (forged pistons, connecting rods) and update the ECU firmware. Without modifications, the engine runs the risk of “breaking apart” due to detonation.

For daily use it is better to limit soft tuning: replacing the exhaust system with straight pipe, installation of cold intake and chip tuning. This will add 20–30 hp without damaging the resource.

Restoration and care: how to keep Laurel in perfect condition

If you purchased Laurel 1986 for restoration, start with anti-corrosion treatment. Best to use ML-mastic or Dinitrol for hidden cavities. Body panels can be restored using welding or fiberglass, but original spare parts are difficult to find - most often they use analogues from Nissan Bluebird or Stanza.

For engine CA18ET critical regular oil changes (every 5,000 km) and monitoring the antifreeze level. Turbine requires semi-synthetic oil (For example, Liqui Moly 10W-40) and a mandatory “run” before stopping the engine (let it idle 1–2 minutes).

Pay special attention in the salon leather trim (if it is preserved) - it can be restored using leather conditioner (For example, Leather Honey). Clean plastic panels without aggressive agents so as not to damage the original texture.

Comparison with competitors: why Laurel is better than Bluebird and Stanza

In 1986 Nissan offered several middle class sedans, but Laurel C31 stood out against their background in several ways:

Characteristics	Nissan Laurel C31	Nissan Bluebird U12	Nissan Stanza T11
Body length, mm	4 620	4 530	4 490
Trunk volume, l	520	480	460
Availability of turbo version	Yes (CA18ET)	No	No
Drive type	Rear	Front/Full	Front

Laurel was positioned as a more premium model: better sound insulation, rich equipment (electrical accessories, climate control) and more powerful engines. Unlike Bluebird, y Laurel there was an independent rear suspension, which improved handling. And compared to Stanza, it offered greater comfort and status.

⚠️ Attention: If you need a reliable car for your daily commute, Bluebird U12 with motor CA20E It will be more practical - cheaper to maintain and easier to repair. Laurel more suitable for enthusiasts willing to invest in restoration.

FAQ: Frequently asked questions about Nissan Laurel 1986

Which engine is the most reliable?

Among naturally aspirated engines CA20E is considered the most durable - with proper maintenance it can easily pass 300,000+ km. Turbo version CA18ET requires more attention, but with timely replacement of oil and coolant it also lasts a long time. The main thing is to avoid overheating and use high-quality fuel (at least AI-95).

Is it possible to install the engine from a Silvia S13?

Yes, CA18DET from Silvia S13 installed on Laurel C31 with minimal modifications: the flywheel, clutch basket and, possibly, the pan will need to be replaced. You will also need to adapt the wiring to a different ECU. Such a swap adds 50–70 hp and improves dynamics.

How much does a complete restoration cost?

The cost depends on the condition of the car. Basic restoration (body + engine) will cost 300,000–500,000 rubles. A complete rebuild with painting, interior replacement and tuning can achieve 1,000,000+ rubles. The most expensive elements are body work and original interior parts.

What kind of oil should I pour into the engine?

For naturally aspirated engines (CA18S, CA20E) semi-synthetic is suitable 10W-40 (For example, Mobil Super 2000). For turbo version (CA18ET) it is better to use synthetics 5W-40 or 10W-40 with permission API SG/SH (For example, Liqui Moly Optimal). Important: the oil in the turbine must be heat resistant!

Where can I find the original documentation?

Original manuals Nissan Laurel C31 can be downloaded from sites like NicoClub or ManualsLib. Repair books from the publisher are also useful "Behind the Wheel" (series “Foreign Cars”). For electrical diagrams, we recommend searching FSM (Factory Service Manual) at Japanese auctions.
