Both SOHC and DOHC versions have an aluminum head. The SOHC versions have 2 valves per cylinder and the DOHC versions have 4 valves per cylinder, all cam lobes move only one valve. All RB engines have belt driven cams and a cast iron block. All turbo models have an intercooled turbo (except the single cam RB20ET & RB30ET engines), and most have a recirculating factory blow off valve (except when fitted to Laurels and Cefiros) to reduce boost surge when the throttle is closed. Single overhead cam (also SOHC) refers to the internal combustion engine design where one camshaft is located above the valves. ...
A double overhead cam (also called a dual overhead cam, DOHC, or twincam) engine is a type of internal combustion engine where the camshafts that operate the intake and exhaust valves are mounted above the cylinders, and where there are separate camshafts for inlet and exhaust valves. ...

The first RB20E/ET/DE/DET engines were fitted to the R31 Skyline. The early twin cam engines are generally referred to as 'Red Top' engines because they have red cam covers. The early twin cam engines featured the NICS (Nissan Induction Control System) injection system, while the single cam engines always used ECCS (Electronically Concentrated Control System). The RB20E was also fitted to some Holden Commodores sold in New Zealand, and to the A31 Cefiro. The Z31 200ZR was fitted with an intercooled RB20DET.

RB24S This is a relatively unknown engine, as it was not produced for the Japanese domestic market. These were fitted to some left hand drive Nissan Cefiros exported from Japan new. Mechanically it is made from an RB30E head, RB25DE/DET block and RB20DE/DET crank with 34 mm height pistons. This engine used carburretors instead of the Nissan ECCS fuel injection system. It is able to rev harder than the RB25DE/DET (as it has the same stroke as the RB20DE/DET) as well as being almost the same displacement as the RB25DE/DET. A common modification is to fit a twin cam head from other RB series motors while retaining the carburreted set-up. The standard single cam form produced 141 PS @ 5000 rpm and 20.1 kgf·m (197 N·m) of torque @ 4400 rpm. Torque applied via an adjustable end wrench Relationship between force, torque, and momentum vectors in a rotating system In physics, torque (or often called a moment) can informally be thought of as rotational force or angular force which causes a change in rotational motion. ...

- RB25DE - twin-cam 140 kW/190 PS and 147 kW/200 PS (with VCT) @ 6000 rpm, 255 N·m (26.0 kgf·m) @ 4000 rpm)
- RB25DET - twin-cam turbo (T28 Turbo) (245 to 250 hp and 319 N·m)
- NEO RB25DET - twin-cam turbo (206 kW (280 PS) @ 6400 rpm, 362 N·m (37.0 kgf·m) @ 3200 rpm)
RB25DE and DET engines produced from August 1993 also featured NVCS (Nissan Variable Cam System) for the intake cam. This gave the new RB25DE more power and torque at lower rpm than the previous model. Nissan Variable Cam Timing (commonly known as N-VCT or VCT or NVCS) is an automobile variable valve timing technology developed by Nissan. ...
In automotive engineering, an intake manifold or inlet manifold is a part of an engine that supplies the fuel/air mixture to the cylinders. ...
In May 1998 a NEO head was fitted, which enabled the engine to be classified as a low emission vehicle engine (LEV). The non-VCT and non-turbo was fitted to the R32 Skyline, the VCT turbo and non-turbo was fitted to R33 Skylines and Stageas. R34 Skylines also use these engines, but they are fitted with a NEO head.
RB26DETT The first 2.6 L RB26DETT featured twin-turbochargers and produced around 280 HP (206 kW) @ 6800 rpm and 260 ft·lb (353 N·m) @ 4400 rpm. The last series of the RB26DETT produced 280 PS (206 kW) @ 6800 rpm and 289 ft·lb (392 N·m) @ 4400 rpm. However, several stock (unmodified) engines have been dyno tested and reported to obtain around 330 HP mark. The reason some RB26DETTs put out 330HP, is because of a now defunct Gentlemen's Agreement with the Japanese government, every car was restricted to 276HP. It is commonly accepted that Nissan chose to not advertise the RB26's true power for this reason. It is widely known for its strength and extreme power potential. It is not uncommon for 600 hp to be achieved on the standard bottom end. With regular maintenance, many of these engines have been driven way past the 100,000 mile mark with a few heading toward 200,000 miles.

Originally the R32 GT-R was planned to have a 2.4L RB24DET, and compete in the 4000 cc class (in Group A rules, the displacement is multiplied by 1.7 if the engine is turbocharged). This was when Nismo was going through the process of designing the R32 GT-R to be a Group A race car. But when the engineers added the AWD system, it would make the car heavy and less competitive. Nismo made the decision to make the engine a 2.6L twin turbo, and compete in the 4500 cc class, resulting in the RB26DETT known today.[5] The Nissan Skyline GT-R is an iconic Japanese sports coupé in the Nissan Skyline range. ...

RB26DETT Z2 This is the engine used in the Nissan Skyline GT-R Z-Tune. It is basically the RB26 block, modified with Nismo parts, bored and stroked to 2.8 L (87.0 x 77.7 mm). The end result was the RB26 Z2, which puts out 500 hp (368 kW) and 540 N·m of torque [6]. They originally aimed for 630 hp, but the engine had to be de-tuned after problems were encountered with high emission values.

RB30 Three models of 3.0 L RB30 were produced: - RB30S - carbureted single-cam
- RB30E - fuel-injected single-cam (114 kW @ 5200 rpm, 247 N·m (25.2 kgf·m) @ 3600 rpm)
- RB30ET - fuel-injected single-cam turbo (150 kW)
This motor was produced because the Holden 202 (3.3 L) powering the Holden Commodore could no longer satisfy emissions requirements, and with all new cars required to run on unleaded petrol by 1986, a quick replacement was needed. Nissan Motor Co. teamed up with GM to build their biggest displacement RB, the 3-litre RB30E. The RB30ET was only found in the VL Commodore. The RB30E suffered issues with the cylinder head cracking due to the radiator being fitted lower in the engine bay that the cylinder head causing air locks in the water galleries in the head. This issue was mosly related to being fitted to the Commodore although the Skyline did suffer this issue to a lesser extent also. The engine proved to be very reliable other than this issue. The RB30S was found in some Middle Eastern R31 Skylines and in some Nissan Patrols. The RB30E was found in R31 Skylines and VL Commodores in Australia as well as in South African R31 Skylines (with 126 kW @ 5000 rpm and 260 Nm @ 3500 rpm) The Holden Commodore is an automobile produced by the Holden division of General Motors (GM) in Australia. ...

The turbocharged RB30ET (producing 150 kW) was found only in the VL Commodore (available in all trim and specification levels from SL to Calais) and consisted of a lower compression RB30E bottom end, more powerful oil pump, T3 Garrett turbocharger, 250 cc injectors and a different intake manifold. The motor itself is still popular today (albeit in highly modified form) on the Australian Drag Racing circuit. Nissan Special Vehicles Division Australia produced two limited runs of 200 R31 Skylines, the GTS1 and GTS2. These contained slightly more powerful RB30E engines. - GTS1 RB30E - injected single-cam (130 kW @ 5500 rpm, 255 Nm (26.0 kgf·m) @ 3500 rpm) - special cam profile, special exhaust[7]
- GTS2 RB30E - injected single-cam (140 kW @ 5600 rpm, 270 N·m (27.5 kgf·m) @ 4400 rpm) - special cam profile, special exhaust, piggy back computer, valve porting[8]
RB30DE These rare engines were used in the Tommy Kaira M30 based on the R31 Skyline GTS-R. It delivered 177 kW (240 PS) @ 7000 rpm and 294 N·m (30.0 kgf·m) @ 4800 rpm. Apparently the engine was made up of a RB30 bottom end mated to a modified RB20DE head. These engines also exist as a hybrid conversion using a RB30 bottom end and a RB25DE head.
RB30DET
RB30DET - R31 RB30E block, R32 RB25DE head. Nissan did not produce this engine, but it refers to a turbocharged engine featuring an RB30E block with a twin-cam head conversion. Common hybrid in Australasia using a RB30E bottom end mated to a RB25DE,RB25DET or RB26DETT cylinder head and turbo (RB20DE and DET heads are generally not used as there's little or no flow improvement). The RB25DE cylinder head from the R32 Skyline, A31 Cefiro or C33 Laurel can be used, and fits almost directly on (although better valve springs are required to prevent valve float when running any more than stock boost). The RB25DET (from the R33 Skyline or C34 Laurel or Stagea) head is also used, however an external oil feed must be fabricated for the variable cam timing on the RB25DET, and the galleries at the front of the engine do not line up. The variable cam timing may be disconnected altogether.

The fitment of a twin cam head from any of these engines onto a standard compression RB30E bottom end gives an ideal compression ratio for a mild to moderately modified street turbo engine, making the conversion popular amongst those who would otherwise convert their RB30E to a high compression RB30ET using original ET bolt on externals. Although it has a larger displacement than the RB26DETT, maximum possible horsepower is less, as the RB30 block lacks the RB26 block's internal cast-in bracing, and consequently cannot rev as high due to harmonic issues at ~7500 rpm. To compensate, the RB30DET produces more torque at lower revs. There is also an 'RB30DETT' kit manufactured by OS Giken of Japan, which bolts an extension on top of the RB26 engine block, and fits liners, to give an 86 mm bore x 86 mm stroke. It is available as an assembled short block, containing billet chrome-molybdenum crank, billet chrome-molybdenum H-beam connecting rods, forged pistons, and costs ¥1,500,000.[9]
RB-X GT2 The RB-X GT2 (also called REINIK) is an engine specially made for the Nismo 400R. The difference between this engine and a RB26DETT is that the engine is bored and stroked (87.0 × 77.7 mm) which results in 2771 cc. Engine gives out 400 PS (331 kW) at 6800 rpm and 47.8 kgf·m (469 N·m or 347 lbf·ft) at 4400 rpm [10]. This engine comes with a reinforced cylinder block and cylinder head, metal head gasket, pistons with cooling channels, forged crank shaft, forged connecting rods, N1 turbine with reinforced actuator, high flow air cleaner, stainless down pipe, and low air resistance sport catalizer, most of which were not offered for the RB26DETT. The Nissan Skyline GT-R is an iconic Japanese sports coupé in the Nissan Skyline range. ...
