Legendary Nissan Silvia S15 - the latest generation of the iconic line of rear-wheel drive coupes, which has become an icon of the Japanese tuning movement. But few people know that in addition to standard coupes and hatchbacks, there was also a **convertible version** - a rare incarnation S15, released in limited quantities. This model, officially known as Nissan Silvia S15 Varietta, combines an aggressive coupe design with an open top, making it one of the most desirable cars among collectors and enthusiasts JDM.

Unlike serial S15, the convertible was not produced by ourselves Nissan - it was created by the company Autech (subsidiary Nissan), specializing in exclusive modifications. Total released less than 600 copies, which makes this car a real rarity. In the article we will analyze technical features, weak points, tuning options and purchase nuances - everything you need to know before purchasing or modifying Silvia S15 Convertible.

Technical specifications Nissan Silvia S15 Convertible

Under the hood S15 Varietta hiding the same time-tested engine SR20DET — 2.0-liter turbocharged unit, which has become a legend due to its reliability and tuning potential. However, due to the design features of the convertible, some parameters differ from the standard coupe.

Basic version develops 250 hp (by Japanese standards), but actual power at the wheels is often lower due to transmission losses and additional weight. The gearbox is a 6-speed manual (optional 4-speed automatic), and the drive, like all Silvia, exclusively rear. Convertible weight: 100–150 kg morethan the coupe, which affects the dynamics: acceleration to 100 km/h takes about 6.5–7.0 sec against 5.8–6.2 sec for the standard version.

  • 🔧 Engine: SR20DET (2.0L, turbo, 250 hp according to JDM standard)
  • 🔗 Transmission: 6 manual transmission or 4 automatic transmission (optional)
  • ⚖️ Weight: ~1,350 kg (100–150 kg heavier than coupe)
  • ⚡ Acceleration 0–100 km/h: 6.5–7.0 sec (depending on transmission)
  • 🛣️ Max. speed: ~230 km/h (electronically limited)

A special feature of the convertible is a reinforced frame and additional stiffening ribs that compensate for the lack of a hard roof. However, body torsional rigidity is lowerthan the coupe, which is noticeable at high speeds and during aggressive driving. The suspension remained the same (Multi-link behind and MacPherson front), but the shock absorbers and springs are often softer to compensate for the extra weight.

  • SR20DET (stock)
  • SR20VE (atmo, VTC)
  • CA18DET (swap)
  • 2JZ-GTE (swap)

Differences between the convertible and the standard Silvia S15

Main difference S15 Varietta from the coupe is, of course, a soft top. The roof is electrically controlled and folds behind 20–25 seconds, but only at speeds up to 5 km/h. The mechanism is reliable, but requires regular maintenance: lubrication of the guides and checking the hydraulic cylinders. When folded, the roof occupies part of the trunk, reducing its volume by 250 l to 120 l.

Externally, a convertible can be easily recognized by:

  • 🚗 Reinforced sills and rear arches (to compensate for the loss of rigidity)
  • 🔄 Unique taillights (slightly narrower than the coupe)
  • 🔺No rear spoiler (as standard)
  • 🔒 Additional reinforcements in doors and side members

The changes in the interior are minimal: the same seats Recaro (in top versions), steering wheel Nismo and an instrument panel with white dials. However, the soft top means noise levels are higher and the cabin can be cooler in winter. The climate control in the convertible is more efficient than in the coupe, but its capabilities are limited when the roof is open.

Why is the Silvia S15 Convertible so rare?

Production was limited due to the high cost of reworking the body (strengthening, roof mechanism) and low demand in the Japanese market. Most copies remained in Japan, and export versions (for example, to Australia) are even rarer.

Weaknesses and typical problems

Despite its legendary status, Silvia S15 Convertible has a number of “diseases” that you should know about before purchasing. The main problem is corrosion. Due to the open design and additional welds, rust often appears:

  • 🛠️ At the places where the roof mechanism is attached
  • 🚪 On thresholds and lower parts of doors
  • 🔧 Under the rear arch seals

Second Achilles' heel - electrician. The roof mechanism, climate control units and airbags (if equipped) often fail. Particularly vulnerable:

  • 🔌 Wiring in doorways (grinds when opening/closing)
  • 💡 Roof position sensors (may give false positives)
  • 🔋 Battery (discharges faster due to additional consumers)
⚠️ Attention: Before purchasing, be sure to check the operation of the roof mechanism manually (in case of an electrical failure). If the roof does not open/close using the remote control, this may indicate wear on the hydraulic cylinders or problems with the control unit.

The third common problem is suspension. The extra weight causes the shock absorbers and bushings to wear out faster. Original racks Kayaba or Tokico serve about 80–100 thousand km, after which they require replacement. Also, the silent blocks of the rear suspension often “get tired”, which is manifested by knocking noises on uneven surfaces.

Knot Typical problem Service life (thousand km) Repair cost (approx.)
Roof mechanism Worn hydraulic cylinders, leaking seals 100–150 150–400 thousand rubles.
Electrical wiring Short circuit in door harnesses 120–150 50–200 thousand rubles.
Suspension Wear of shock absorbers and bushings 80–100 80–150 thousand rubles.
Body Corrosion of thresholds and arches Depends on care 100–500 thousand rubles.

Tuning and modifications: what can be done with a convertible

Tuning Silvia S15 Convertible has its own nuances. The main limitation is body rigidity. Installing a powerful motor (for example, RB26DETT or 2JZ-GTE) requires serious strengthening of the subframes and side members, otherwise the body will simply “fall apart” under high loads. However, moderate tuning is quite possible.

Popular modification directions:

  • 🔥 Engine:
    • Stock SR20DET with turbine upgrade (Garrett GT28 or Tomei)
    • Swap on SR20VE (atmo, 200+ hp with VTC)
    • Installation CA18DET (for lovers of the classics)
  • 🛞 Suspension:
    • Coilovers Tein or BC Racing (adjustable hardness)
    • Reinforced stabilizers Cusco or Nismo
    • Polyurethane bushings Whiteline
  • 🎨 Exterior:
    • Installing a rear spoiler (eg Nismo or Mine’s)
    • Carbon mirrors and diffuser
    • Vintage alloy wheels Work Equip or Rays TE37

Particular attention should be paid when tuning a convertible security. Due to the open roof it is recommended:

  • 🚨 Install a roll bar (for example, Cusco or Sparco)
  • 🔄 Replace standard belts with 4-point ones (for example, Takata)
  • 🛡️ Strengthen the side members with welded plates

How much does a Nissan Silvia S15 Convertible cost in 2026?

Prices for S15 Varietta vary greatly depending on condition, mileage and ownership history. In Japan, clean copies with mileage up to 80 thousand km cost from 3.5 to 5 million yen (~1.8–2.5 million rubles). In Russia and the CIS countries prices start from 2.5 million rub. for project cars and reach 5–7 million rubles. for perfect copies with documentation.

Factors influencing cost:

  • 📄 Availability of complete service history (plus 20–30% to the price)
  • 🔧 Roof mechanism condition (repairs cost 150–300 thousand rubles)
  • 🎨 Original body and interior (tuned cars are cheaper)
  • 🚗 Availability of swap or forced engine (can either increase or decrease the price)

When purchasing, pay attention to:

  • 🔍 Condition of the side members (often rot from the inside)
  • 🔋 Electronics operation (especially the roof and climate control mechanisms)
  • 🛢️ Oil leaks (typical for SR20DET after 150 thousand km)
⚠️ Attention: There are often “converted” convertibles on the market - coupes that have been artificially fitted with a soft roof. They can be distinguished by the absence of factory body reinforcements and non-standard mechanism fastenings. Please inquire before purchasing VIN and check the history through Japanese auctions (USS, TCV).
💡

When inspecting, pay attention to the body number under the hood - for original convertibles it starts with RS15-100*** (for Varietta).

Operation and care: tips for owners

Service Silvia S15 Convertible requires more attention than a standard coupe. Here are the key points:

1. Care of the soft roof:

  • 🧴 Clean the roof with special means (for example, Renovo Soft Top Cleaner) every 3 months.
  • 🚿 Do not wash your car in a high-pressure car wash - the jet of water can damage the mechanism.
  • 🔧 Once a year, lubricate the roof guides with silicone grease.

2. Corrosion prevention:

  • 🛡️ Treat thresholds and arches with anticorrosive (Dinitrol or Tectyl) every 2 years.
  • 🔍 Check the drainage holes in the doors and trunk - their blockage leads to moisture accumulation.

3. Engine Maintenance:

  • 🛢️ Change the oil every 5–7 thousand km (synthetic 5W-40 or 10W-40).
  • 🔥 Check the turbine for play every 50 thousand km.
  • 🔧 Once every 100 thousand km change the timing belt and rollers (a break leads to bending of the valves).

4. Winter operation:

  • ❄️ Avoid long trips with the roof open in temperatures below +5°C — the roof fabric becomes fragile.
  • 🚗 Store the car in a heated garage or use a roof cover.
💡

Regular maintenance of the roof mechanism and anti-corrosion treatment is the key to the longevity of the Silvia S15 Cabriolet. Neglecting these procedures leads to expensive repairs within 3–5 years.
