Nissan Skyline R28 (1972-1977): the legendary Hakosuka with L20A engine

Nissan Skyline R28 — this is not just a car, but a symbol of the era. Released in 1972 as a successor R23, he became the last of the first generation of "hakosuka" (from Japanese "box-shaped"). This Skyline is remembered not only for its angular design, but also for its revolutionary technical solutions at the time, including an independent rear suspension and powerful in-line six-cylinder engines. Today, the R28 is a rare piece treasured by collectors and tuners around the world.

Unlike later Skyline models, R28 did not have turbo engines or electronic control systems. Its strength lies in its simplicity and reliability: manual transmission, rear-wheel drive and series engines L, which, with proper tuning, produce impressive results. In this article we will analyze the technical features, weaknesses and upgrade options Nissan Skyline R28, and also tell you why it is still relevant in the drift and retro crowd.

Technical characteristics of Nissan Skyline R28

Under the hood Skyline R28 two main engines were installed: L20A (2.0 l) and L24 (2.4 l). Both units belonged to the series Nissan L, known for its reliability and tuning potential. Basic version with L20A developed 130 hp, and the top GT-R (which, however, was not officially produced in the R28 body) could boast 160+ hp after modifications. Transmissions were offered in 4- and 5-speed manuals, as well as a 3-speed automatic (optional for the US market).

The suspension deserves special attention: front - double wishbones, behind - independent multi-link (in cheaper versions - spring axle). Disc brakes at the front and drum brakes at the rear (all-round discs on top versions). Body R28 weighed about 1100 kg, which combined with rear-wheel drive made it an excellent platform for drifting and track racing.

• 🔧 Engines: L20A (2.0 l, 130 hp), L24 (2.4 l, 150 hp)
• ⚙️ Gearboxes: Manual transmission-4, manual transmission-5, automatic transmission-3
• 🚗 Drive: rear (FR)
• ⚖️ Weight: 1080–1150 kg (depending on configuration)

Differences between the Nissan Skyline R28 and previous generations

R28 became a logical continuation of the Hakosuka line, but with a number of key improvements. Unlike R23, it received a more rigid body, a modified front suspension and an increased choice of engines. For example, version 2000GT-X equipped L20A with two carburetors Hitachi, which gave an increase in power up to 140 hp without major modifications. Also in R28 For the first time, the option of air conditioning and electric windows appeared - a luxury for Japanese cars of the early 70s.

Externally R28 different from R23 a more massive radiator grille, modified rear lights and a slightly elongated body. The interior has become more comfortable: sound insulation has improved, more ergonomic seats have appeared, and the dashboard has a round speedometer and tachometer (instead of the rectangular ones on earlier models). However, the main difference lies in chassis: Nissan engineers strengthened the side members and added additional stiffening ribs, which had a positive effect on handling.

⚠️ Attention: Many body parts R28 not interchangeable with R23, especially suspension components and engine mountings. When restoring or tuning, take this into account to avoid compatibility problems.

Weaknesses and typical problems of the Nissan Skyline R28

Despite its legendary status, Skyline R28 has a number of “diseases” that you should know about before purchasing. The main problem is corrosion. Hakosuka bodies are prone to rust at the bottom of the doors, sills and rear arches. Cars operated in countries with salty roads (for example, Japan or the USA) are especially vulnerable. The second typical malfunction is suspension wear. Over 50 years of operation, rubber bushings and silent blocks almost always require replacement, and original parts are difficult to find.

Series engines L reliable, but have their own nuances:

• 🔥 Overheat: The weak point is the thermostat and water pump. When the engine boils, the block head is often deformed.
• ⚙️ Carburetors: Hitachi or Solex require regular cleaning and adjustment. Clogged jets lead to unstable operation.
• 🛢️ Maslozhor: When driving over 200 thousand km, oil seals and piston rings often wear out.

⚠️ Attention: Upon purchase Skyline R28 be sure to check the condition of the frame and side members. Many examples had accidents, after which the body was welded homemade. Use a magnet to find the putty and inspect the welds.

How to check the L20A engine before purchasing?

1. Start the engine when cold - there should be no knocking or detonation.

2. Check the compression in all cylinders (normal: 11–13 bar, variation no more than 1 bar).

3. Inspect the oil filler neck for the presence of emulsion (a sign of a broken cylinder head gasket).

4. Make sure that the carburetors are synchronized (you can check by ear or using a vacuum gauge).

Tuning Nissan Skyline R28: from aspirated to turbo kits

Thanks to its simple design and robust chassis, Skyline R28 — an ideal platform for tuning. Most popular destinations:

• 🔥 Atmospheric tuning: installation of three carburetors Mikuni Solex 44PHH, camshafts Nissan N1, increasing the compression ratio to 10:1. Such modifications make it possible to squeeze out L20A to 180–200 hp.
• 🌀 Turbo kits: turbine adaptation from RB20DET or SR20DET with intercooler and higher performance injectors. Power grows up to 250+ hp, but requires strengthening the chassis.
• 🚗 Suspension: replacing springs with coil springs, installing adjustable shock absorbers Tokico Illumina or KYB, reinforced anti-roll bars.
• 🎯 Brakes: upgrading to disc brakes all around (for example, from Skyline R32) with a vacuum booster.

Often used for drifting differential lock (For example, Nismo or Cusco) and a reinforced gearbox with a short-throw rocker. External tuning is usually limited to original parts: spoilers Nissan Motorsport, widened arches and alloy wheels Watanabe or Enkei.
