What engines are on the Nissan Skyline: a complete guide to models and generations

When it comes to Nissan Skyline, most car enthusiasts immediately imagine the legendary RB26DETT or VR38DETT — engines that have become symbols of Japanese tuning and drifting. But the history of this model goes back decades, and the list of engines installed in different generations is much wider. From humble inline-fours to monstrous twin-turbocharged V6s, the choice depends on the generation, market, and owner's goals.

In this article we will look at all Nissan Skyline engines, from classic models from the 1960s to modern ones Infiniti Q50/Q60 (which are essentially the successors to Skyline). You will learn which engines are considered the most reliable, which ones are best avoided when buying a used car, and how to choose an engine for specific tasks - be it everyday driving, drag racing or drifting. We will also touch upon questions engine swap, legalization in Russia and service features.

1. History of Nissan Skyline engines: from G15 to VR38DETT

First generation Skyline (1957–1963) equipped with a simple engine G15 with a volume of 1.5 liters and a power of only 60 hp. It was a typical representative of the post-war Japanese automobile industry - reliable, but far from sporting ambitions. Everything changed in 1964 with the release Skyline 2000 GT (S50), which received 2.0-liter G7 inline-six engine - the first in the line with an overhead valve (OHV) mechanism.

The real breakthrough came in 1969 with the debut Skyline GT-R (KPGC10), nicknamed "Hakuosha" ("White Devil"). Under its hood stood the legendary S20 - 2.0-liter inline six with double camshaft (DOHC) and 160 hp. This engine became the basis for the Skyline's future racing victories in the Japanese championships and laid the foundation for the model's reputation as a "Porsche killer".

In the 1980s, Nissan switched to a series RB, which became famous thanks to turbocharged versions:

• 🔧 RB20E - naturally aspirated 2.0 l (130–155 hp), installed on the basic versions of the R30/R31.
• 💨 RB20DET — turbocharged version (180–210 hp), popular among drifters.
• 🏁 RB26DETT — 2.6 l, twin turbocharged, 280 hp. (officially, in reality - up to 320+ hp), heart Skyline GT-R R32/R33/R34.

In the 2000s, Nissan abandoned the RB series in favor of VQ And VR. The latter became the pinnacle of engineering - VR38DETT (3.8 l, V6, twin turbo) produced 480–600 hp. depending on generation GT-R R35.

2. Legendary motors: RB26DETT and VR38DETT in detail

RB26DETT The most iconic engine in Skyline history. Developed in the late 1980s, it became the basis for racing and tuning projects. Here are its key features:

• 🔥 Construction: Cast iron block, aluminum heads, 24 valves, DOHC.
• 💨 Turbines: two Garrett T25 (on R32) or T28 (on R33/R34), sequential arrangement.
• ⚙️ Limiter: Japanese versions were artificially limited to 280 hp. (gentleman's agreement), but real power is 320+ hp.
• 🛠️ Weaknesses: oil pump, turbines (lifespan ~100 thousand km), cylinder head gasket when overheated.

The RB26DETT can handle up to 500-600 hp. on a stock block with proper tuning, but requires strengthening of the transmission and suspension.

VR38DETT (installed on GT-R R35 since 2007) is a modern approach:

• 🔥 Materials: aluminum block with cast iron liners, forged pistons and connecting rods.
• 💨 Turbines: two IHI with variable geometry, boost pressure up to 1.2 bar.
• 📊 Power: 480 hp in the basic version, 600 hp. in Nismo and special versions.
• ⚠️ Problems: high cost of repairs, sensitivity to oil quality, complexity of chip tuning due to closed ECU firmware.

Why is the RB26DETT still popular?

Despite its age, the RB26DETT remains in demand due to its simple design (compared to the VR38), huge spare parts database and tuning potential. For example, a stock block can withstand up to 1.5 bar of boost without major repairs, and the cost of a swap in Skyline R32/R33 starts from 300 thousand rubles (versus 1.5 million+ for VR38).

Parameter	RB26DETT (R32/R33/R34)	VR38DETT (R35)
Volume, l	2.6	3.8
Power (stock), hp	280 (actually 320+)	480–600
Turbines	Garrett T25/T28	IHI variable geometry
Resource before overhaul, km	200–250 thousand	150–200 thousand
Swap cost (used), rub.	300–800 thousand	1.5–3 million

⚠️ Attention: Upon purchase Skyline GT-R R35 with a mileage of more than 100 thousand km, be sure to check the compression in the cylinders and the condition of the turbines. VR38DETT is sensitive to overheating - even one temperature increase can lead to deformation of the block heads.

3. Atmospheric and turbo engines for everyday use

Not all Skyline owners race on the track. Many people choose this model for style, comfort and reliability. For such tasks, naturally aspirated or moderately boosted engines are suitable:

• 🚗 RB25DE (2.5 l, 190–200 hp) - naturally aspirated version of the RB-series, installed on Skyline R33/R34 in basic configurations. Pros: reliability, low fuel consumption (10–12 l/100 km), ease of maintenance. Cons: weak dynamics compared to turbo versions.
• 💨 VQ35DE (3.5 l, V6, 280–300 hp) - engine from Skyline V35/V36 (2001–2007). Aspirated with variable phase control, known for its “indestructible” reputation. Resource before overhaul - 300+ thousand km.
• 🔥 SR20DET (2.0 l, turbo, 205–250 hp) - four-cylinder engine, installed on Skyline R32/R33 in versions GTS-t. Popular among drifters for its light weight and responsiveness to tuning.

VQ35DE — the best choice for those who value reliability and comfort. This motor does not require frequent maintenance, is easy to repair and has a huge spare parts database. For example, the timing chain is designed for 200 thousand km, and the variable phase system VVEL (in later versions) improves traction at low speeds.

If you're looking for a balance between performance and practicality, look no further than VQ37VHR (3.7 l, 330 hp) from Skyline V36 (2007–2013). This engine combines high power with relatively low consumption (13–15 l/100 km) and a service life of 250+ thousand km.

4. Which engine should I choose for tuning?

If your goal is maximum power, the choice of engine depends on the budget and type of tuning:

1. Drift/time attack:
   • 🏁 SR20DET — light weight, good balancing, cheap tuning (turbine TD05-18G + intercooler = +100 hp).
   • 💥 RB25DET — 2.5-liter RB version with a turbine, potential up to 400–500 hp. on the stock block.
2. Drag racing:
   • 🚀 RB26DETT with boost to 600–800 hp. (reinforced block, turbine Garrett GTX42, fuel system ID2000).
   • 🔥 VR38DETT - for those who are willing to pay for modern technologies (potential 800–1000 hp on a prepared block).
3. Budget project:
   • 💰 CA18DET (1.8 l, turbo) - cheap, but requires improvements (weak block, oil pump).
   • 🔧 SR20DE (aspirated) - you can turbo for 200-300 thousand rubles.

RB26DETT remains a favorite among tuners thanks to:

• 🔧 Ease of modifications (open ECU, many ready-made solutions).
• 💰 Availability of spare parts (including used ones from Japan).
• 🏆 Time-tested reliability (with proper maintenance).

For Skyline R35 tuning VR38DETT is much more expensive. For example, replacing turbines with GReddy or HKS will cost 500–700 thousand rubles, and chip tuning with firmware Cobb Accessport - another 150-200 thousand.

Heavy Duty Oil Pump (N1)|Garrett GT3582R Turbo or equivalent|Larger Intercooler|1000cc+ Fuel Injectors|Heavy Transmission (OS Giken or PPG)|Control System (Haltech or Link ECU)-->

⚠️ Attention: When boosting the RB26DETT to 500+ hp. be sure to strengthen crankshaft And connecting rods. Stock parts can handle up to 450 hp, but the risk of connecting rod breakage increases dramatically at 6000+ rpm.

5. Engine swap: what can be installed in Skyline?

One of the main advantages Skyline — possibility of installing engines from other Nissan models. Here are the most popular options:

Engine	Where from	Power (drain)	Swap difficulty	Notes
RB20DET	Skyline R31/R32	210 hp	Low	Direct replacement for RB20DE, requires mounting and wiring.
1JZ-GTE	Toyota Chaser/Mark II	280 hp	Average	Requires gearbox and ECU adaptation, but gives +100 hp. to RB20.
2JZ-GTE	Toyota Supra	320 hp	High	Expensive (motor ~1 million rubles), but potential 800+ hp.
VQ35DE	Skyline V35/350Z	280–300 hp	Average	Reliable aspirated, but 50+ kg heavier than the RB.
LS1/LS3	Chevrolet Corvette	350–430 hp	Very high	Requires a complete overhaul of the suspension and transmission.

The simplest and most cost-effective swap - RB20DET in Skyline R32/R33. The engine is installed almost “like original”, and the power grows to 250–300 hp. after chip tuning. For Skyline V35/V36 swap is popular VQ35DE to VQ37VHR - this gives an increase of 50 hp. without major modifications.

1JZ-GTE And 2JZ-GTE - options for those who want to get the most out of it. For example, 2JZ with turbine Garrett GT42 produces 600–700 hp. on a stock unit, but the swap will cost 1.5–2 million rubles (including the box, wiring and ECU settings).

6. Problems and reliability: what to look for when buying?

Each engine Skyline has its own “diseases”. Here's what to check first:

• 🔧 RB-series (RB20/25/26):
  • 🛢️ Oil pump - wears out after 150 thousand km, leading to a drop in oil pressure.
  • 🔥 Cylinder head gasket — burns out when overheated (especially on RB26).
  • 💨 Turbines - resource Garrett T25/T28 — 80–100 thousand km.
• 🔧 VQ-series (VQ35/VQ37):
  • 🔌 Ignition coils - fail after 100–150 thousand km.
  • 🛢️ Oil leaks - through the valve cover and rear crankshaft oil seal.
  • ⚙️ Timing chain — stretches to 200 thousand km (control is needed).
• 🔧 VR38DETT:
  • 💻 ECU - closed firmware, difficult to chip without specialized equipment.
  • 💰 Turbines — replacement costs 300–500 thousand rubles.
  • 🔥 Overheating — leads to deformation of the heads (repair ~500 thousand rubles).

Upon purchase Skyline with mileage required:

1. Check the compression in the cylinders (the norm for RB/VQ is 12–14 bar).
2. Inspect the oil for metal shavings (a sign of worn turbines or bearings).
3. Scan ECU errors (codes P0299 - low boost pressure, P0300 — misfires).
4. Make sure that the motor is original (on the RB26 there are often “assembled” engines from different donors).

7. Legalization and registration of swapped engines in Russia

In Russia, engine swap in Nissan Skyline requires official registration. Here are the key points:

1. Documents: The new engine must be included in the title. For this you need:
   • 📄 Declaration of Conformity (if the motor is certified for this model).
   • 🔧 Conclusion of preliminary technical examination (for non-certified swaps).
   • 🚗 Diagnostic card after refurbishment.
2. Cost: Legalization costs 50–150 thousand rubles (depending on the region and complexity of the swap).
3. Difficulties:
   • 🚫Motors 1JZ/2JZ (from Toyota) are not officially certified for Skyline - expertise will be required.
   • ✅ RB26 → RB25 or VQ35 → VQ37 are easier (one line of engines).

If you do not plan to legalize the swap, the car will not pass inspection, and the insurance may be invalidated in the event of an accident. An alternative is registration as a “homemade vehicle” (STS), but this is a long and expensive process (200–300 thousand rubles).

⚠️ Attention: Upon purchase Skyline with a non-original engine, ask the seller for documents for the swap. Without them, you will not be able to register the car, and converting it back will cost 100–200 thousand rubles.

8. Service and spare parts: where to buy and how much does it cost?

Maintenance cost Skyline depends on the engine:

Engine	Maintenance cost (oil + filters), rub.	Resource before overhaul, km	Cost of overhaul, rub.	Where to buy spare parts
RB20DE/RB25DE	8–12 thousand	250–300 thousand	150–250 thousand	Japan (Aucnet), local showdown
RB26DETT	12–18 thousand	200–250 thousand	300–500 thousand	JDM stores (RHDJapan, JDM Garage)
VQ35DE/VQ37VHR	10–15 thousand	300+ thousand	200–400 thousand	Official dealers, eBay
VR38DETT	20–30 thousand	150–200 thousand	800 thousand–1.5 million	Official channels only (Nissan)
SR20DET	6–10 thousand	200–250 thousand	120–200 thousand	Disassembly, AliExpress (Chinese analogues)

For RB-series Most spare parts can be found at Japanese auctions (Aucnet, ) or in local showdowns. For example, a contract RB26DETT costs 300–500 thousand rubles, and a set of pistons JE or Wiseco — 50–80 thousand

For VQ/VR parts are more expensive and it is better to buy them from official dealers or trusted suppliers (for example, Z1 Motorsports for VR38). Turbines for VR38DETT (IHI or GReddy) will cost 200–400 thousand rubles per set.

Cost overhaul depends on the motor:

• 🔧 RB26DETT: 300–500 thousand rubles (with replacement of turbines, pistons, connecting rods).
• 🔧 VQ35DE: 200–400 thousand rubles (most often the timing chain and oil seals need to be replaced).
• 🔧 VR38DETT: 800 thousand–1.5 million (due to the complexity of the design and the high cost of spare parts).

❓ What engines were installed on the Nissan Skyline R32?

On Skyline R32 (1989–1994) the following engines were installed:

• RB20DE — 2.0 l, naturally aspirated, 155 hp.

• RB20E — 2.0 l, naturally aspirated, 130 hp. (basic versions).
• RB26DETT — 2.6 l, twin turbocharged, 280 hp. (GT-R).
• CA18DET — 1.8 l, turbo, 170 hp. (less often, mainly for export).
• SR20DET — 2.0 l, turbo, 205 hp. (GTS-t).

The most popular - RB26DETT, but for everyday use it is better to choose RB20DET or SR20DET.

❓ Which engine is the most reliable for Skyline?

In terms of reliability, the leaders are:

1. VQ35DE — naturally aspirated V6 with a service life of 300+ thousand km, minimal problems.
2. RB25DE — an atmospheric version of the RB-series, easier to maintain than the turbo versions.
3. SR20DE - four-cylinder naturally aspirated, cheap to repair.

Turbo engines (RB26DETT, VR38DETT) are less reliable due to the complexity of the design and sensitivity to oil quality.

❓ Is it possible to install an engine from an Infiniti Q50 in a Skyline V36?

Yes, VQ37VHR (3.7 l, 330 hp) from Infiniti Q50 (2014+) compatible with Skyline V36 (2006–2013) since it is one platform (N
