In this article I’m going to discuss the RB26DETT engine vs VR38DETT engine. These two engines are very similar in some ways, but they do have some differences as well. The first one is a more powerful engine, while the latter is a more efficient one. You’ll need to take these two factors into consideration if you’re planning on using one of them.
The Nissan RB engine is a straight-6, oversquare, four-stroke gasoline engine. The engine was produced from 1985 to 2004 and is set to resume production in 2019. The RB engine is an evolution of the VG-series V6 engines of the ’80s and ’90s. It offered a full range of modern power in both a straight and V layout.
The RB26DETT engine is built using an aluminum cylinder head. Its valvetrain features dual overhead camshafts. The valves in the RB26DETT engine have four valves for each cylinder. The engine features two Garrett T25 turbochargers with ceramic impellers. The RB26DETT engine produces 276 horsepower at 6,800 rpm.
This engine can reach a boost level of up to 57 PSI. However, it is best not to over-rev or boost this engine. This could tarnish its reputation and make it unable to perform at its peak. A reliable RB26 engine is dependent on proper tuning and general maintenance.
The RB26DETT engine is very similar to Toyota’s 2JZ-GTE engine, but is designed differently. While the 2JZ-GTE uses an individual cap, the RB26DETT utilizes a full girdle design. Unless you want to get your hands on a car with over 800 wheel horsepower, you should opt for the higher-performance 2JZ-GTE.
Oiling problems are common in the RB26DETT engine. A narrow drive collar in the oil pump makes it difficult for the oil pump to get oil at high rpms. This can cause oil starvation. To avoid this problem, you should install an aftermarket oil pump. However, you must be aware of the high cost of a good RB26DETT oil pump.
Nissan’s RB26DETT engine was first released in 1989. It was produced at Yokohama and was used in Nissan’s R32 Skyline GT-R. It had an excellent racing history and a good tuning potential. This engine has the ability to throw 1,800 horsepower on the dyno.
The RB26DETT was available in the Nissan Skyline GTR from 1989 to 1994. It received bespoke tuning and refinements with each generation. The most common NISMO upgrade is a modified version of the original. This engine can be used with a turbocharger or a supercharger. The turbos in the Skyline GTR were ceramic and often failed in high-heat race conditions. Steel-impeller turbos are a more reliable choice.
The RB26DETT engine is one of the most popular Nissan engines in the world. When modified, it can reach over 500 horsepower. Its 2.6L inline-six engine features twin Garrett T28-type ceramic turbochargers that produce 10 psi of boost. The RB26DETT engine also boasts six individual throttle assemblies.
Originally, the RB26 engine was designed to produce 316 horsepower. Its forged internals and iron block make it extremely powerful. It was found in the Skyline GT-R 32 and R33. In Japan, the government put restrictions on the power of the RB26 to improve safety. However, some owners removed the boost restrictor and found that their cars were capable of over 300 hp.
The Nissan RB26DETT engine was replaced by the VQ30DETT engine in 2001. The Nissan Skyline GT-R Z-Tune has the RB26DETT engine. This engine has more horsepower and 400 lb-ft of torque. The RB26DETT engine is also easy to upgrade with aftermarket parts. Many popular modifications include an oil pump and fuel pressure regulator.
The Nissan Skyline GTR is a dream car for a generation of kids. Its streetability and ability to accept modifications make it a tuner’s dream. Its RB26DETT engine is the heart of the car and features Garrett turbochargers low on the passenger side of the seven-main-bearing iron block. It is capable of delivering up to 330 horsepower, which is an excellent stock horsepower for a street-friendly car.
The Nissan VR series of twin-turbo DOHC V6 automobile engines features displacements ranging from 3.0 to 3.8 liters. These engines are the evolution of the successful VQ series and are inspired by the R390 GT1 Le Mans racing engine. However, these engines are not limited to Nissan vehicles.
The VR38DETT is a 3.8-liter V6 that produces over 480 horsepower. While this might not sound like a lot, the engine can rival the power of a mid-engine supercar. In fact, Nissan’s NISMO tuning team has been working on upgrading this engine for over a decade. The company has upgraded the turbos and fuel and ignition systems. Although the engine is capable of more horsepower, Nissan is being conservative in its upgrades to prevent overheating the engine.
The VR38DETT engine was originally designed for the Nissan R35 GT-R, but it is now also found in the limited-run Nissan Juke-R. Nissan is continuing to refine the VR38DETT motor by adding more power and torque. The engine is also being used in Nissan’s popular Skyline franchise.
The VR38DETT engine is made from lightweight, yet durable aluminum alloy. Its cylinder head is also made from light alloy for good cooling efficiency. Two IHI RHF55 turbochargers are installed in the VR38DETT engine. The result is an engine that can reach 196 mph and 315 km/h on the racing circuit. Despite the high power output, the VR38DETT is extremely reliable.
The VR38DETT engine was first introduced in the Nissan GT-R aka Godzilla in 2007. It later found its way into the Nissan Juke-R. It is a twin-turbocharged 3.8-liter V6 gasoline engine with plasma sprayed bores. It uses IHI RHF55 twin turbochargers to produce 13 psi of boost.
The VR38DETT engine is capable of producing 500-550 horsepower with the proper modifications. Its horsepower increase depends on the year model of the car and the condition of the engine. The VR38 engine can be further enhanced with high-flow fuel injectors, aftermarket exhaust, sports catalyst, and a ported and polished head.
The Nissan VR38 engine is a reliable engine and does not show any major design flaws. However, if you plan on increasing the power output of the VR38DETT, it is important to use a good tuner. Proper tuning of the transmission can minimize the chances of your R35 GT-R breaking the connecting rods.
The Nissan VR38DETT engine is a turbocharged V6 engine with variable valve timing. It has been manufactured at Nissan’s plant in Tochigi since 2007. Its high-performance features include a titanium muffler, a GT3-spec camshaft, and an intercooler and turbocharger.
The VR30DDTT engine, another member of the VR38DETT family, is a slightly cheaper alternative to the VR38DETT. It can deliver 300 or 400 horsepower with stock internals, although it is not nearly as powerful as the VR38DETT. The VR30DDTT engine is capable of producing up to 800 horsepower when tuned.
If you want to increase the power of your VR38, you must invest in high-quality internals and good driving habits. This engine is not cheap to upgrade, so you will need to save some money for it. Moreover, the engine is an extremely complex piece of engineering and a bit of a challenge.
The VR38DETT is not the most reliable in stock form, and you may not like the analog feel of the gearbox. However, with the right mods, you can increase the power output of your R35 GT-R by 600 hp. You can also upgrade the internals of the engine. For example, you can consider installing forged pistons, titanium rods, larger turbos, and larger injectors.
