Nissan Silvia S12 (1983-1988): the legendary sports car with a turbo engine

Nissan Silvia S12 - an iconic Japanese sports car of the 80s, which became a bridge between classic S110 and revolutionary S13/S14. This model, released in 1983, was remembered not only for its aggressive design, but also for its innovative solutions for its time: turbocharged engines, rear-wheel drive and the possibility of deep customization. Today S12 - A rare example on the secondary market, prized by both collectors and drifters.

In this article we will look at all key aspects models: from technical specifications to typical problems that haunt owners 30+ years after release. You will find out what modifications Silvia S12 are considered the most reliable, how to properly tune a turbo engine CA18DET, and why this car is still relevant in the drift community. And if you are planning a purchase, at the end of the article you will find a checklist for inspection before the transaction.

History of creation and generation of Nissan Silvia S12

Model S12 debuted in 1983 as successor Silvia S110 (known in the US as Datsun 200SX). The main task of engineers Nissan was to create a car that would combine sportiness with everyday practicality. The result was a coupe with aerodynamics unique for that time (Cx coefficient = 0.34) and a wide selection of engines - from atmospheric to turbocharged.

Production S12 lasted until 1988, during which time the model underwent several updates:

• 📅 1983–1985 - first generation with rectangular headlights, engines CA18E (atmo) and CA18ET (turbo).
• 🔄 1986 (facelift) — new bumpers, a modified radiator grille and engine appeared CA18DET with intercooler.
• 🌍 Export versions — for the USA and Europe they were produced under the brand Datsun/Nissan 200SX with naturally aspirated engines CA20E.

Interesting fact: Silvia S12 became the first model Nissan, on which it was installed electronic engine control unit (ECU) with the possibility of chip tuning. This opened up wide possibilities for modifications that are still actively used today.

Technical characteristics: engines, transmissions, suspension

With my heart Silvia S12 steel series engines CA, which were distinguished by their reliability and potential for tuning. Below is a comparative table of the main modifications:

Engine model	Volume	Power (hp)	Torque (Nm)	Features
CA18E	1.8 l	105–115	147–152	Atmospheric, 2 valves per cylinder, carburetor/injector
CA18ET	1.8 l	130–140	186–190	Turbo, no intercooler, T3 hot turbo
CA18DET	1.8 l	165–175	226–231	Turbo with intercooler, 370 cc injectors, ECU with chip tuning
CA20E	2.0 l	110–120	167–172	Atmospheric, export version for USA/Europe

Transmission on S12 was offered in three versions:

• 🔧 5-speed manual transmission — the most reliable and desirable for tuning.
• 🔄 4-speed automatic - rare, weak point - torque converter.
• 🚗 3-speed automatic — installed on earlier versions, not recommended for purchase.

Suspension Silvia S12 built according to the classical scheme: in front - MacPherson struts, behind - multi-lever. This ensured good handling, but also had weaknesses: the silent blocks of the rear levers and wheel bearings wore out quickly. Often installed for drifting adjustable shock absorbers (For example, Tein or Koni) and reinforced stabilizers.

Weaknesses and typical problems of the Nissan Silvia S12

Nissan Silvia S12 - a car with a considerable age, and even with careful care it has “diseases” that every potential owner should be aware of. Here are the main ones:

• 🔥 Engine overheating - everyone's weak point CA-motors. Causes: clogged radiator, faulty thermostat or cooling fan. At temperatures above 105°C, the aluminum cylinder head may fail, leading to expensive repairs.
• 🛢️ Oil leaks — crankshaft and camshaft seals, valve cover gasket. On turbo engines CA18DET/ET Oil often flows through the turbine (a sign of worn seals).
• ⚡ Electrics - oxidation of contacts in the fuse box, problems with the generator (especially on cars with air conditioning). The throttle position sensor often fails (TPS).
• 🔩 Suspension — wear of ball joints, silent blocks of rear levers, wheel bearings. On cars that drive hard, springs often crack.

Particular attention should be paid turbocharged versions. Turbine T3 on CA18ET has a resource of about 150–200 thousand km, after which it requires replacement. On CA18DET The intercooler often rusts from the inside, resulting in a loss of pressure. Also check the condition fuel pump - on older cars it may not provide enough pressure for the turbo engine.

How to check the turbine on S12 without removing it?

1. Start the engine and let it warm up.

2. Pinch the hose going from the turbine to the intercooler - if the turbine is working properly, you will feel pressure 2-3 seconds after pressing the gas.

3. Look at the exhaust: bluish smoke during over-gassing is a sign of wear on the turbine seals.

4. Check the turbine shaft play: if there is any play, the turbine has “died”.

⚠️ Attention: On Silvia S12 with engine CA18DET Often they fake power by increasing the boost without upgrading the fuel system. If the seller claims more than 200 hp. on a stock engine - ask for a dyno test!

Tuning Nissan Silvia S12: from chip tuning to engine swap

Silvia S12 — one of the most “tuning-resistant” cars of its time. Even stock CA18DET can be safely overclocked to 220–250 hp without major modifications. Let's consider the main directions of modernization:

1. Engine and turbo

• 🔧 Chip tuning - ECU firmware (for example, Haltech or Nistune) allows you to increase power by 20–30 hp. without mechanical modifications.
• 💨 Turbine upgrade - replacement of stock T3 on T25 or T28 gives an increase of up to 280–300 hp, but will require strengthening the fuel system (550 cc injectors, fuel pump Walbro 255).
• ⚙️ Strengthening the insides - for power above 300 hp. you need forged pistons, connecting rods and a lightweight crankshaft.

2. Transmission

Stock box S12 withstands up to 250–280 hp, but for greater power it is recommended:

• 🔗 Install enhanced grip (For example, Nismo or Spec).
• 🔄 Replace the box with 5-speed from S13/S14 — it is more reliable and has better gear ratios.
• 🛠️ Strengthening axle shafts and CV joints is a weak point during aggressive driving.

3. Suspension and brakes

For drifting or track, the following are required:

• 🔩 Adjustable suspension - for example, BC Racing or Stance with the ability to adjust ground clearance and rigidity.
• 🚗 Reinforced stabilizers - from Cusco or Nismo.
• 🛑 Brake system — replacing stock calipers with 4-piston ones (for example, from S13) and installation of ventilated discs.

Popular for those who want radical changes engine swap. Most often installed:

• 🔥 SR20DET — reliable and powerful (up to 300+ hp on a stock unit).
• ⚡ RB20DET - for extreme buildings (400+ hp), but will require modification of the engine compartment.
• 💣 1JZ-GTE or 2JZ-GTE - rare, but found among enthusiasts.

Nissan Silvia S12 in drifting: why is it still relevant?

Despite his venerable age, Silvia S12 remains a popular car in the drift community. Reasons:

1. Light weight - about 1000–1100 kg (depending on modification), which makes it very responsive to gas and steering.
2. Rear wheel drive with good weight distribution (52/48), which is ideal for controlled drifting.
3. Low price compared to S13/S14, which allows novice drifters not to be afraid of damage.
4. Easy to repair - details CA-motors are cheaper and more accessible than those SR or RB.

Famous drifters such as Keiichi Tsuchiya (founder Option Magazine), began their careers precisely on S12. Today the machine is often used in grassroots-drift (amateur competitions) and as a base for buildings in the style kaido racer (Japanese street racing from the 80s and 90s).

For drifting S12 usually modified as follows:

• 🔧 Install hydraulic handbrake for better control of skidding.
• 🔄 Change differential ratios at 4.11 or 4.375 for better acceleration.
• 🛠️ Strengthen subframe and install safety cage.

⚠️ Attention: In preparation S12 for drifting, be sure to check the condition rear axle bearings - they often wear out due to lateral loads. Also make sure that fuel tank securely fastened (on old cars the fastenings rust).

How to choose a Nissan Silvia S12 on the secondary market?
