History of Nissan Skyline engines: from L-series to VR38DETT

First Skyline (1957–1960s) were equipped with modest in-line fours of the series G And L, but the real revolution occurred in 1969 with the advent of the model KPGC10 and its engine S20 - the first production engine with DOHC in Japan. This unit developed 160 hp (by Japanese standards of the time) and became the basis for racing versions.

In the 1980s Nissan presented the legendary RB-series, who became famous thanks to the model R32 Skyline GT-R with RB26DETT. This engine became a symbol of the era: twin-turbo, cast iron block, forged pistons and the potential to boost up to 500+ hp. without major repairs. At the same time, atmospheric versions were produced RB20/25DE for civil modifications.

In the 2000s Skyline moved to the platform V35/V36where they debuted VQ motors (For example, VQ35DE), and later - VR38DETT in GT-R R35. The latter, despite belonging to a different model, is often associated with Skyline due to historical continuity.

  • 🔧 1960–1970s: S20 (KPGC10), L20/L24/L28 (atmospheric and turbo).
  • 🚀 1980–1990s: RB20DET, RB25DET, RB26DETT (GT-R R32/R33/R34).
  • ⚡ 2000s: VQ30DD, VQ35DE, VQ37VHR (V35/V36).
  • 💥 2007–present time: VR38DETT (R35 GT-R, indirectly related to Skyline).

RB26DETT: the legendary GT-R R32/R33/R34 engine

RB26DETT - the most famous engine Skyline GT-R, produced from 1989 to 2002. This 2.6-liter inline six-cylinder unit was equipped with two turbines Garrett T25, system NICS (Nissan Induction Control System) and forged internals.

  • ❌ Problems with the injection system (injectors and fuel injection pumps require cleaning every 50 thousand km).
⚠️ Attention: During operation GT-R R35 or Skyline with VR38DETT be sure to use oil 5W-40 or 0W-40 with permission Nissan. Cheap analogues lead to premature wear of turbines and piston groups.

Which Skyline engine to choose: comparison for different tasks

The choice of engine depends on your goals:

  • 🏁 For track and drift: RB26DETT (potential 500+ hp, reliable block) or SR20DET (cheaper in tuning).
  • 🚗 For daily driving: VQ35DE (atmospheric, resource) or RB25DET (if you need a turbo engine with a balance of power and reliability).
  • 💰 Budget option: SR20DE (atmospheric version SR20DET, 150–160 hp).
  • 🔥 For maximum power: VR38DETT (but be prepared for high maintenance costs).

Upon purchase Skyline with mileage, be sure to check:

Diagnostic scanner for errors (especially for oxygen and detonation sensors)|Compression in cylinders (for turbo engines)|Condition of turbines (play, oil in the intercooler)|Oil leaks (cylinder head gasket, oil seals)|Service history (oil change, timing belt/chain)-->

If you are planning tuning, budget for:

  • 🔧 Reinforced gearbox (for power over 400 hp. stock Getrag can't stand it).
  • 🛑 Brakes (standard calipers Skyline designed for 300–350 hp).
  • 🌀 Intercooler and pipes (for turbo engines, replacement with aluminum ones is required).

Tuning Skyline engines: from chip tuning to complete overhaul

Tuning potential Skyline depends on the engine:

  • 🔧 RB26DETT:
    • 📈 Stage 1 (350–400 hp): firmware, downpipe, boost controller.
    • 📈 Stage 2 (450–500 hp): turbines Garrett GT2860, fuel system, intercooler.
    • 📈 Stage 3 (600+ hp): forged pistons, reinforced connecting rods, large turbines (GTX3582R).
  • 🔧 SR20DET:
    • 📈 Stage 1 (250–280 hp): firmware, 3" exhaust, boost 1.2 bar.
    • 📈 Stage 2 (300–350 hp): turbine T28, injectors 550cc, fuel pump Walbro 255.

For VQ35DE popular compressor kits Stillen (+100–150 hp) or turbo kits GReddy (+200–250 hp), but they require strengthening the transmission.

What happens if you fill the Skyline GT-R with 92-octane gasoline?

Using 92 gasoline instead of 98 gasoline on the RB26DETT or VR38DETT leads to detonation, overheating and destruction of the pistons. This is especially dangerous for engines with a high compression ratio or turbocharging. At best, you will get a drop in power and errors in the knock sensor; at worst, a major overhaul.

Maintenance and operation: how to extend the life of the Skyline engine

Engine life Skyline depends on compliance with the maintenance regulations:

  • 🛢️ Oil change: every 5–7 thousand km (for turbo engines - only synthetics 5W-40 or 0W-40).
  • ⚙️ Timing Belt/Chain:
    • RB-series: belt - every 80–100 thousand km.
    • SR20DET: chain - check every 150 thousand km.
    • VQ35DE: chain - resource 200+ thousand km (but requires monitoring of tensioners).
  • 🔥 Turbines: checking the play every 50 thousand km, changing the oil in the turbine when changing the engine oil.
  • ❄️ Cooling system: replace antifreeze every 2 years, check the thermostat and pump.

For turbo engines Skyline It is critical to follow the “warm up and cool down” rule:

  • 🔥 Before driving, let the engine warm up until 40–50°C (1-2 minutes at idle).
  • ❄️ After active driving, let it idle 1–2 minutes before shutting down (to cool the turbines).
💡

Ignoring warming up the turbo engine leads to premature wear of the turbines and oil starvation. This is especially true for the RB26DETT and VR38DETT, where the turbines operate under high loads.

FAQ: Frequently asked questions about Nissan Skyline engines

Which Skyline engine is the most reliable?

Among turbo engines, the leader in reliability is RB25DET (less forced version RB26DETT). Among the atmospherics - VQ35DE (resource 300–400 thousand km).

Is it possible to install VR38DETT in Skyline R34?

Technically possible, but it would require a complete overhaul of the suspension, transmission and electronics. The budget for such a swap is from $20,000. It is much easier and cheaper to boost the stock one RB26DETT.

How much oil does the RB26DETT consume?

Normal consumption - up to 0.5 l per 1000 km. If the engine "eats" more, check the oil rings and valve seals. On turbo engines, oil consumption is always higher than on atmospheric ones.

What kind of gasoline should I put in the Skyline GT-R?

Minimum octane number - 98. For forced engines (400+ hp) it is recommended 100+ or racing fuel (eg VP Racing). The use of 95 gasoline leads to detonation and destruction of the pistons.

Which is better: RB26DETT or 2JZ-GTE?

Both engines are legendary, but RB26DETT lighter (50+ kg), more compact and better balanced for a front-wheel drive/all-wheel drive platform Skyline. 2JZ-GTE more powerful in stock and easier to tune, but heavier and requires modifications to the chassis.
