Describe an RB engine.
You’ve probably heard of the term “RB engine” if you’re into JDM automobiles. The designation RB, which serves as the engine code for the RB-engine series, is considered to stand for “Race-bred” or “Rhythm & Balance.” Nissan debuted the RB series in 1985, and it was improved upon until 2004. Despite the fact that RB26 version manufacture resumed in 2019,
RB engines came in straight-6, four-stroke, 2.0–3.0 liter sizes. The L20a six-cylinder Nissan engine, which shared a bore and stroke size with the RB20, the first RB engine, served as the basis for the actual engine. RBs have a cast-iron block, belt-driven cams, and an aluminum head. With the exception of the RB20ET and RB30ET versions, the turbo models have an inter-cooled turbo.
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 distinguishes an RB26 from an RB30DET?
Despite having a larger displacement than the RB26DETT, the RB30 block’s maximum theoretical horsepower is lower because it lacks the internal cast-in bracing of the RB26 block and thus cannot rev as high due to harmonic problems at around 7500 rpm. Due to its longer stroke, the RB30DET makes up for this by producing higher torque at lower rpm.
Beginning in August 1985, the HR31 Skyline and Nissan Fairlady 200ZR (Z31 chassis) were built and equipped with the first RB20ET/DE/DET engines. The Nissan Induction Control System (NICS) injection system was present in early twin cam engines, whereas ECCS was used in later twin cam engines (Electronic Concentrated Control System).

An RB in an automobile is what?
Nissan’s oversquare 2.0-3.0 L straight-6 four-stroke gasoline engine, known as the RB engine, was manufactured from 1985 to 2004 and will resume production in 2019 following a 15-year break. The RB offered a comprehensive, contemporary variety in both straight and V layouts after the 1983 VG-series V6 engines.
What models of Nissan have RB engines?
The demand for period-correct, original parts is exploding as Skyline GT-Rs establish themselves as one of the hottest collector vehicles on the rise. At the end of 2017, Nissan’s NISMO Heritage program moved up with a preliminary list of new factory-refurbished parts, but now things are serious as the RB26 engine from Godzila is returning to production.
The 2.6-liter engine’s block and heads are currently cited as being on the manufacturing schedule on the NISMO Heritage website in Japanese, with shipping starting on April 1. The block and head cost 170,000 and 187,000 yen, or roughly $1536 and $1690, respectively. It’s unclear whether that fee includes shipping, which may significantly increase the price for users outside of Japan.
For Skyline fans, who are typically ready to spend top dollar for an original engine or specialized parts, this news will undoubtedly come as a blessing.
The Nissan Skyline GT-R versions R32 (1989–94), R33 (1995–98), and R34 (1999–2002) are most recognized for using the RB26. With an aluminum head, six separate throttle bodies, oil-cooled pistons, dual turbocharging, and more, it produced 276 horsepower at 6800 rpm and 266 lb-ft of torque at 4400 rpm in the R32 Skyline. Even by today’s standards, it is smooth and elegant while being a technological marvel.
Nissan followed up with additional parts for the R33 and R34 models in late 2018, however they were primarily tiny hoses, trim pieces, wiring harnesses, and the like. NISMO Heritage started supporting R32 parts in late 2017. For the R33 and R34, wiper motors and reservoirs for the windshield washer fluid are now available; nevertheless, in addition to the key engine parts for the R32, there are also fuel pumps, muffler assemblies, and body items such fenders, roofs, and front spoilers.
We have contacted NISMO in Yokohama for more information, and we will update this article as we learn more. JDM lovers currently have every reason to rejoice, and we anticipate Nissan’s list of Heritage goods to grow over time.
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.
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.
What does RB26’s RB stand for?
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.
Which is superior, RB25 or RB26?
The RB engines stand out from other engines and have always been the greatest in terms of both their technical features and appearance. The superb quality, usability, longevity, and low fuel consumption of RB engines are well known. Well, two RB engines with even more power and economy are the RB 25 and RB 26.
There are many differences between the RB 25 and RB 26 engines. The RB 25 is a 2.5 L, 2498 cc engine with an 86.00 mm bore and 71.7 mm stroke. The RB 26 is a 2.6 L, 2568 cc engine with an 86.0 mm bore and 73.7 mm stroke.
The RB 26 engines’ superior power over the RB 25 engines is another distinction. Additionally, the RB 26 features solid lifters while the RB 25 has hydraulic lifters. The RB 25 engine is less expensive than the RB 26 engine when their prices are contrasted.
There are three different varieties of RB 25 engines: RB 25 DE, RB 25 DET, and NEO RB 25 DET. The RB 25 DE and RB 25 DET engines were first produced in 1993. The RB 25 DET was given a NEO head in 1998.
From 1998 through 2002, RB 26 engines were largely employed. The RB 26 engines also come with six separate throttle bodies, which is an additional function. The engines also include a parallel twin turbo system. Among all Nissan RB engines, the RB 26 DETT engine is referred to as the king. The RB 26 engine is capable of producing 1400 hp.
The capacity of the RB 25 and RB 26 also varies. The RB 26 has a capacity of 2566 cc, compared to the RB 25’s capacity of 2498 cc. The RB 25 DE and RB 25 DET both have 190 and 250 horsepower, respectively, at 5600 rpm. The RB 26 has 280 horsepower at 5600 rpm, in contrast.
RB 26 engines are more potent than RB 25 engines, to start with.
2. The RB 25 engines had a 2.5 L, 2498 cc displacement and a bore and stroke of 86.00 mm and 71.7 mm, respectively. The RB 26 engine, on the other hand, is a 2.6 L, 2568 cc engine with an 86.0 mm bore and a 73.7 mm stroke.
3. RB 26 engines have solid lifters, while RB 25 engines have hydraulic lifters.
4. The price difference between the RB 25 and RB 26 engines.
5. The RB 26 engine has six separate throttle bodies, which is an added function.
How trustworthy are RB engines?
In general, RBs are renowned for their dependability and longevity. But ultimately, every car develops problems, and given the age of these engines right now, that shouldn’t really be a surprise.
There are no complaints of any significant design problems, which would have definitely surfaced by now, if they were properly maintained utilizing the recommended service intervals and high-quality lubricants.
One of the most worrying problems is with RB25s used for circuit, drag, or drifting, which are frequently pushed to, or past, their limitations for extended periods of time. Owners in this instance discover too much oil in the cylinder head and catch can but insufficient oil in the sump.
Fitting an external oil return from the back of the cylinder head to the sump is one of several potential fixes. However, if you’re having these issues, it would be wise to review all of the suggestions to see which ones apply to your particular situation.
Overfilling can result in bearing failure due to oil rush. This frequently occurs when owners have filled up to the “H” mark on the dipstick, which is around 10 mm above the “full” line, during track use.
We strongly advise against exceeding 0.9 bar of boost because doing so will surely result in an early turbo failure.
Installing an oil cooler is advised, especially in hotter climates or for drivers who enjoy pushing their vehicles. In either case, it’s advised that you pay particular attention to the oil temperatures when driving aggressively.
Failure of the ignition coils, which can result in misfires, is a minor issue. However, replacing the coils is a simple fix, and it is advised to do it every 60,000 miles anyhow.
Additionally, there is a tendency for the cam angle sensors to occasionally cause problems. There are several internet solutions to the issue, however switching it out is usually the best option.
In addition, like with other cars, we have heard several stories of technical problems. However, it hardly comes as a surprise and might come down to anything considering their advanced age and how some of them are treated.
In general, RB engines are very dependable, and a healthy engine will be delighted to give you durability all the way up to 400 horsepower using factory internals.
