The RB26DETT engine, which was also used in the R32 and R33 GTR Skylines, is found in the Nissan Skyline GTR R34.
A 2.6 liter (2568cc, to be exact) twin-turbocharged inline-six engine is the RB26DETT.
The cylinder head is made of an aluminum alloy and has a total of 24 valves. The engine block is made of cast iron (DOHC, 4 valves per cylinder)
The RB26DETT was originally rated at 276bhp, but as you may know, historically there was a “gentleman’s agreement” in the Japanese auto industry that manufacturers would limit the stated output of their cars to 276bhp (sometimes the figure is reported as 280PS, but the precise number is less important than the fact that manufacturers did comply on paper with this limit).
Nissan merely understated the figure on technical and sales documents to comply with the agreement; the original RB26DETT is thought to have actually had an output closer to 316bhp.
Although several contemporaneous reviews continued to refer to the 276bhp power output, by the time the R34 GTR’s production was complete, the advertised power output was the higher 316bhp amount.
It’s also important to remember that Nismo created a version of the RB26DETT N1 engine specifically for Group A and Group N racing. Upgraded pistons and piston rings, updated camshafts, and upgraded turbochargers were just a few of the differences (in particular, the turbine wheels in the Garrett GT25 turbochargers are made from steel as opposed to ceramic used in the regular engine).
To create your ideal Skyline GTR, it is possible to buy an upgraded N1 block, however it is very pricey.
In fact, if you Google “GTR N1 block,” you’ll find a ton of forum and blog results where GTR owners—both existing and potential—provide information and ask and answer questions on changing an ordinary RB26DETT to a N1 block.
Since the upgraded block is thought to have a higher nickel content and thicker cylinder walls, making it more appropriate for significant power boosts, enthusiasts frequently advise utilizing it.
There are a variety of potential sources for a N1 block (or other N1 parts) upgrade depending on where you reside, including specialized importers and perhaps even your local authorized Nissan representative. Remember that supply can be difficult, especially given the present Covid climate!

Specifications
All of the Nissan Skylines built for the movie were R34s (the model itself was introduced back in 1998). The RB26DETT 2.6-liter, DOHC, 24-valve straight six that powers the R34s in the movies is force-fed by twin turbos and is officially rated at 280 horsepower. It is positioned longitudinally in the engine bay. The R34’s engine drives an ATTESA all-wheel-drive system, which electronically adjusts the torque split, through a six-speed Getrag gearbox.
Additionally, there is Super HICAS four-wheel steering with an electrical feedback control system that ensures exact wheel positioning even in the most difficult conditions. But the R34’s strengthened body shell and new aerodynamic design marked a significant departure from earlier Skylines. This vehicle has new rear wings and under-car diffusers made of carbon fiber.
The R34 also has HRE rims, a C-West spoiler wing, a blue long striped vinyl, and a C-West body kit. The 2.6 liter RB26DETT Twin turbocharger in Brian’s Nissan Skyline GT-R can produce about 330 HP (stock).
Not Only Did the Nissan Skyline R34 GT-R Have All-Wheel Drive, however
The ATTESA E-TS all-wheel-drive system, which has active torque vectoring and can alternately transmit power between the two axles, is another distinguishing characteristic of the Nissan Skyline R34 GT-R. Having said that, many people overlook the Nissan Skyline 25GT-Four, another Skyline R34 with all-wheel drive, because the GT-R is so much wanted.
The Skyline 25GT-Four has an RB25 DE even though it has the same looks as the R34 GT-T. This results in 197 horsepower and 188 pound-feet of torque and no forced induction (255 Nm). It has a four-speed automatic or a five-speed manual transmission. If you’re intending to purchase an R34 GT-R, bear in mind that the Skyline 25GT-Four is a fantastic base for many GT-R-inspired builds and some fake GT-Rs because it comes with all-wheel drive as standard.
A true JDM icon is the Nissan Skyline R34 GT-R V-Spec II.
One of the company’s best designs, the Nissan Skyline R34 GT-R is a true JDM icon in V Spec II form. Recently, Throttle House had the chance to test one that was painted Bayside Blue and compared it to the brand-new Nissan GT-R 50th Anniversary model that was also covered in the same color.
The fifth-generation Nissan Skyline went on sale in January 1999, and Nissan continued to produce it through August 2002. Owners and tuners alike enjoy its 2.6-liter twin-turbocharged RB26DETT inline-six engine, which provides the vehicle’s power. The critics point out that despite the engine’s age, it has been so carefully constructed and tuned that the car barely exhibits turbo lag.
Over the original V Spec, the V Spec II has a few improvements, such as a firmer suspension, bigger rear brake rotors, a carbon fiber hood, aluminum pedals, and a few other changes. It also looks beautiful and is difficult to resist falling head over heals for.
A twin-turbocharged 3.8-liter V6 engine with 562 HP and 466 lb-ft (632 Nm) of torque is present in the most recent GT-R 50th Anniversary Edition. When traveling straight, it is a beast, and when turning, the R34-gen is left for dead. You are reminded that this is a special edition by unique features like the white exterior highlights and “50th Anniversary” emblems.
Which would you choose, a used Bayside Blue R34 GT-R V Spec II or a brand-new GT-R 50th Anniversary, if money were no object? Choosing, choosing…
If history had unfolded a little differently, the RB26DETT legend would not have gained the fame it does today.
2007 saw a worldwide uprising among JDM fans. By installing a V6 under the R35 instead of the customary turbocharged straight-six, Nissan had defiled the history of the GT-R badge.
Those indignant fans failed to realize that Nissan was merely following a prophecy that had started over ten years earlier with the creation of the R34 GT-R.
You see, Nissan’s storied and respected RB26DETT engine almost wasn’t used to power the final Skyline GT-R model.
Both Watanabe, the R34’s designer, and chief engineer Kazutoshi Mizuno intended for the vehicle to be equipped with a V6 engine positioned behind the front axles.
The proposal, however, was scrapped because there wasn’t enough funding to create a V6 with performance deserving of the prestigious GT-R moniker.
Instead, the RB26DETT, which had previously powered the R32 and R33, continued to function and was put to use once more.
After enduring seven years of what economists now refer to as the Lost Decade, Nissan and Japan in general were in the midst of a financial crisis while the R34 was being developed.
The corporation had to refocus as a result of the Nikkei 225’s collapse in 1991 and the subsequent stagnation in interest rates. In 1999, Carlos Ghosn was hired by Nissan to cut expenses since only three of the company’s 46 models were profitable on the domestic market. One of them was not the R34 GT-R.
The principal engineer of the R34, Mizuno-san, had long argued that the RB26DETT engine had reached the end of its useful life and pushed for a brand-new, lighter, and more effective aluminum-block V6 for the R34 GT-R.
The VQ series of Nissan’s V6 engines were already well under development, but creating a high-performance version of this engine for the R34 was thought to be an unacceptable budget overrun.
The creator of the R33 and R34, Watanabe-san, confirmed that the RB26 would have been handed an early retirement if he had his way in a media interview in 2017 about the original plan.
The fundamental idea behind all Skylines, according to him, was to provide clients with cutting-edge technology.
“In keeping with this idea, we wanted to suggest a new Skyline design for the R34 that featured a front mid-ship layout with a V6 engine.
“However, creating a second engine production line for the Skyline’s V6 engine needed a substantial expenditure.
According to history, Watanabe and Mizuno eventually got their dream, but they had to wait until 2007 when the VR38DETT unit, which was itself a derivative of the VQ family, was introduced in the R35 GT-R.
While a road-going R34 GT-R with a V6 engine was never produced, a small number of factory NISMO R34 GT-Rs with twin-turbo V6 engines were produced; nevertheless, they were GT500 race cars.
Better weight balance and a lower center of gravity were cited as reasons why the engineering and design team wanted to switch the road car’s straight-six engine to a V6, respectively.
Three R34 GT-Rs, each powered by a VQ30DETT, competed in the GT500 class of the 2003 All Japan Grand Touring Car Championship (which would later become Super GT).
When the Z33 350Z was introduced in 2004, the Skyline R34 would make its final appearance in JGTC.
How many R34 GTRS are still around?
One of the most recognizable engines to ever come out of Japan is the RB-25, and the one included in the R34 is very special. Standard specification includes a 2.5L engine with six cylinders and a single turbo pumping up to 7 psi.
A Skyline GTR’s engine type.
The R34, a car that came and conquered prestigious marques that sneered at its Nissan badge, is unquestionably the most sought-after GT-R, nevertheless. Its 2.6-liter twin-turbocharged engine had over 276 horsepower and could accelerate the vehicle from 0 to 60 mph in about five seconds.
Do R34s have two turbos?
Owners and tuners alike enjoy its 2.6-liter twin-turbocharged RB26DETT inline-six engine, which provides the vehicle’s power. The reviewers point out that despite the engine’s age, it has been manufactured and calibrated so effectively that there is barely any turbo lag.
Do GT-Rs have four engines?
Both are substantial inline six cylinder engines that are around the same size and weight. The 2JZ-enlarged GTE’s displacement produces the same amount of output, but it reaches its peak power 1,200 rpm earlier than the RB26. Additionally, the 2JZ produces 31 lb ft greater torque at 400 rpm less than the RB. This gives the 2JZ the upper hand.
What does an R34 Skyline cost?
The NHTSA states that an R34 can only be imported into the country before 2024 for use on tracks; it cannot be registered or operated on public roads.
When did the R34 become legal?
The R34 is arguably the best and most well-known Skyline model. The fact that this car seemed so far ahead of its time and is still in such high demand now was one of the reasons it was so well-liked. It is not surprising that the car is still so expensive and in such high demand in 2021.
What makes the R34 so renowned?
In 1989, the Skyline R32 earned the moniker “Godzilla” for its ability to rule Japanese Touring Car Racing. But it was also completely exclusive to Japan, so people outside of Japan could only learn about the GT-R from magazines.
Why is the GT-R dubbed Godzilla?
specs, features, and cost of the GT-R A 3798 cc petrol engine is used. It has an automatic transmission option. The GT-R may get 9.0 kilometers per gallon of petrol, depending on the model and fuel type. The GT-R is a four-seater, six-cylinder vehicle with dimensions of 4710 mm in length, 1895 mm in width, and 270 MM in wheelbase.
