The Nissan Skyline GTS25 sedan and coupe versions were the first to use the RB25 family of engines. Nissan Variable Cam System (NVCS) for the intake cam was also a feature of RB25DE (Naturally Aspirated) and DET (Turbocharged) engines built starting in August 1993. The new RB25DE has more power and torque at lower rpms than the outgoing model as a result. Both the RB25DE and RB25DET have updated electrical systems starting in 1995 (Series 2 Engines), while the RB25DET(S2turbocharger )’s had a ceramic turbine.
wheel as opposed to aluminum. The ignition coil ignitor that was utilized in earlier models was not employed because ignition coils with built-in ignitors were introduced, which was the most noticeable alteration to the system. A new air flow meter, engine ECU, cam angle sensor, and throttle position sensor were also included. The only mechanical change between Series 1 and Series 2 is in the camshafts because the shaft that the Series 2 Cam Angle Sensor inserts into the exhaust cam is slightly different. The standard Mitsubishi CAS was used in the early Series 2, however due to a positioning tooth that occasionally came off, the Black CAS was eventually substituted.
A NEO head was installed in the engine in May 1998, allowing it to be labeled as a low emission vehicle (LEV) engine because of its lower fuel consumption and pollution output. The NEO head had solid lifters in place of hydraulic ones, revised camshafts with on/off solenoid Variable VCT, a hotter 82 degC (180 degF) thermostat, model-specific coil packs, and a revised inlet manifold (the runner diameter is reduced from 50 to 45 mm (2.0 to 1.8 in) to increase air velocity and low end torque), with the RB25DE NEO having two inlets into the inlet manifold. Due to the head’s smaller combustion chamber, model-specific pistons are used to make up the difference. The turbo received the larger OP6 turbine; some models featured nylon plastic compressor wheels and ceramic turbine wheels, while others had steel compressor and turbine wheels. Connecting rods designed for the GT-R were improved for turbo engines. Some also employed a N1 type oil pump and modified the oil pump drive collar on the crank to address the breakage issues brought on by rapid, high revolutions.
Overall, they represent the culmination of 20 years of Nissan RB engine development and are quite a unique engine in their own right.
The R32 Skyline was equipped with the non-VCT, non-turbo RB25DE, while the R33 Skylines and the WNC34 Stagea were equipped with the VCT turbo and non-turbo RB25DE. Later Skyline and Stagea (WGNC34) models utilize the NEO version, while early R34 Skylines use the non-NEO RB.

What does the acronym RB26DETT mean?
I can remember something about a twin turbo at the end that I know is dohc electronic. Thank you to those with experience.
Here is the key:
Nissan used the moniker RB for its engine blocks and series, although despite widespread claims to the contrary, it has no significance.
ECCS, or “Electronically Concentrated Engine Control System,” is denoted by the letter E. In essence, the ECU controls the engine and its operation by using all of the sensors.
What exactly do DE and DET mean?
Off-topic, but in some engines, like the SR20 DET, the T stands for Turbo and the TT for Twin Turbo.
as in RB26DETT
The same engine powers the VQ30 and VQ30DE.
While the engine code is VQ30DE, it is more commonly referred to as VQ30.
GTES-t
The first two letters of the engine code are only manufacturer-used designators; they do not represent a real code. Everyone uses the term “race breed” to emphasize the already strong message that an RB26DETT makes.
Please provide a list of all the good Nissan engines starting with the first two letters if someone can provide evidence to the contrary. the SR, VG, new VQ, and the CA.
The 26 or whatever number represents the engine’s displacement size in cubic centimeters, rounded to the closest hundred cubic centimeters, sans the last two digits. Therefore, the 26 is approximately 2600cc or 2.6 L. Following words are the letters:
Regarding claims that the Japanese don’t code their engines in English, etc. Inquire as to why all Japanese automobiles have English names and part and body numbers (R32, etc.). On the dash (KPH, RPM, etc.) and control panels, English names and lettering are frequently used.
Nissan RB26DETT Engine Information
- RB26DETT is the engine code.
- Format: Inline Twin-turbo DOHC, 6 cylinders, 24 volts
- the 2.6L displacement (2,568 cc)
- Electronic fuel injection is the fueling system.
- 3.42″ Cylinder Bore: 86.9 mm
- 73.7 mm (2.90 in) is the piston’s stroke.
- 8.5:1 compression ratio
- 276 horsepower at 6,800 rpm
- 260 lb-ft of torque @ 4,400 rpm.
- Order of Fire: 1-5-3-6-2-4
The 1989 introduction of the RB26 engine led to its use up until 2002. This RB25DET variant engine, in contrast to its before, makes use of a cylinder block without an oil port. With a cylinder bore of 86.9 mm, a piston stroke of 73.7 mm, and an 8.5 compression ratio, it has an inline-six arrangement.
Contrary to popular belief, RB is merely the name of the engine series and not “Rhythm and Balance” or “Race Bred.” “2600-cc DOHC Electronic Twin Turbo” refers to the 26DETT.
The RB26DETT is one of the interference engines of the RB series that are all produced in Yokohama, Japan. Nissan used the RB26 in the R32 and R33 Skyline GT-Rs, while the R34 model featured a modified version of the engine. Yes, all of these magnificent Skylines were essentially prohibited in the United States.
The RB26 was created with performance in mind and is exceptionally durable. The block is made of cast iron and offers a reliable base for future improvements. The valvetrain includes two overhead camshafts with a total of 24 valves, and the cylinder head is made of aluminum. The exhaust valves are 30 mm in diameter, while the intake valves are 34.5 mm.
In addition, the intake has six 45mm throttle bodies installed rather of one, providing a better response.
Forced induction is handled by two ceramic impeller Garrett T25 turbochargers (T28s in R34). The RB26DETT produces 276 horsepower at 6,800 rpm and 260 lb-ft of torque at 4,400 rpm with a boost pressure of 10 psi (0.69 bar).
Later models, however, have 316 horsepower and 289 lb-ft more torque. The RB26DETT carries four quarts of oil with a viscosity of 7W-30 and weighs around 273 kilograms, or 601 pounds.
Solid lifters, belt-driven cams, piston squirters, and water-cooled, oil-lubricated turbos were features of the RB26DETT engines used in the R32 and R33 GT-Rs. The RB26 receives dual-mass flywheels, stainless steel dump pipes, and ball-bearing turbochargers in the R34.
The Nismo-tuned RB26DETT N1 was essentially a version that had been improved for racing. Additionally, it received stronger rods, pistons, a redesigned manifold, a better cooling system, and turbochargers with steel impellers.
Additionally, the engine’s internal water and oil channels were upgraded. The camshafts were improved, along with the pistons and rings. If you desire to change, the N1 block is compatible with all GT-R engine bays.
Both blocks are plainly distinguishable one from the other. The regular RB26DETT block is marked with 05U, while the N1 is cast with the identification mark 24U.
What does Nissan mean by DETT?
Response Balance 2600cc DOHC Electronic Twin Turbo is referred as as RB26DETT. It is a 2.6-liter inline-six engine with two cams and parallel twin turbos that may be used in the Nissan Skyline GT-R from 1989 to 2002.
What does engine mean by DETT?
DET is an acronym for double (dual) cam, electronic fuel injection, and turbo. I believe VET stands for variable cam as opposed to double. That is how I interpret it. #3 Mar 17, 2011
What does the acronym Nissan SR mean?
Sport Rally refers to the Nissan Altima SR trim level, which is essentially a sportier variant of the base model trim. The 2.0 L turbocharged engine that powers the SR generates 182 HP and 180 ft. lbs. of torque. Additionally, a sports-tuned suspension and the Xtronic CVT transmission will be included.
What does the acronym Nissan RB mean?
It’s a Nissan Patrol that has had an RB25DET rammed up it. Race Bred is referred to as RB. 25 denotes displacement (2.5-litres, in this case). double overhead cam, or D. the fuel injection code E. A turbocharged vehicle. It is also the engine found in the sexiest Skylines, the ancestor of the Nissan GT-R.
As you can see, it revs fairly quickly. Additionally, the driver is eager to locate the limiter. But in a really ridiculous manner, it’s still amazing.
Nissan still produces the RB26, right?
The storied RB26 straight-six engine that propelled the Skyline GT-R32, R’s R33, and R34 generations is now being rebuilt. Well, some of it—Nissan has added another 24 pieces to its collection of Nismo Heritage Parts, which includes important 2.6-liter engine parts.
The program has recently added the block, cylinder head, harness, and exhaust system from the RB26 in addition to a large selection of brand-new parts for the R32/33/34. According to the price list, the block will cost 170,000 yen (PS1180), while the head will cost 187,000 yen (PS1300).
Jalopnik noticed that the RB26DETT N1 block with the stronger part number A1000-RHR30 is also an option. It’s considerably more expensive, though; to get one, you’ll have to fork over 425,000 yen (almost PS3000).
Do you need some R32 body parts? You’re in luck since Nismo will once more produce roof panels, rear wings, and other exterior components for the car that were previously mentioned as part of the plan.
A few of the new parts will arrive later in the year, but the majority of them will be delivered starting on 1 April.
Which Nissan model has an SR20 engine?
It is a well-liked inline four-cylinder engine that is typically seen in the Nissan Silvia and 180SX. Additionally, it was available for the Nissan Bluebird, Nissan NX Coupe, and Pulsar GTI-R. The 180SX and Silvia’s original CA18DE and CA18DET engines were swapped out for this one. The SR20 took the place of the CA18, which was thought to be too expensive to produce and no longer complied with Japanese emission regulations. The SR was a turbocharged intercooled engine in top shape, just like the outgoing CA. Nissan also created the SR20DE, a less expensive normally aspirated variant. The Silvia and 180SX are both marketed as the 240SX in the US and Canada. The SOHCKA24E or DOHCKA24DE were standard equipment on USDM and Canada 240SXs for previous versions. Both engines are naturally aspirated engines and have respective outputs of 155 horsepower (116 kW) and 140 hp (100 kW). The forced induction aftermarket accessories for the SR20DET are making SR20DET engine swaps increasingly frequent. Many businesses only perform SR20DET exchanges.
Which Nissan RB engine is the best?
Nissan’s Skyline GT-R was originally made available in 1989 with the BNR32. Nissan engineers fitted the Skyline with the biggest and most potent variant of its RB engine series, the RB26DETT, with the goal of racing in Group A competition as its primary purpose. Iron serves as the engine block and aluminum serves as the cylinder head in an inline six-cylinder engine. High engine speeds were made possible by the RB26DETT’s 73.7mm stroke, which was relatively short. For N1 endurance competition, the robust RB26 block was also offered in a N1 variation that had more ribbing for strength. The GT block was the third and most valuable variant. Only 1,000 GT blocks were produced for racing teams, and they had the most strengthening of any RB26 ever made available. The only clue that the block is a GT block is three raised “R”s on the side. Shim under bucket direct-actuation valvetrain was used in the dual overhead cam aluminum cylinder head for increased dependability at high RPM. The RB engine, which can produce over 1,400 horsepower, has dominated sports competitions on the drag strip and in racing circuits. With a 3-liter limit, it provides fantastic specific output. The aftermarket has embraced the RB26, creating overboring techniques that can increase the RB’s displacement to over 3-liters as well as stroker kits, deck plates, and other accessories. Unfortunately, America was excluded from all of this excellence, which caused it to plummet to number four on the list.
