The RB Engine is a straight six, oversquare gasoline engine made by Nissan. It was produced from 1985 until 2004. In 2019, Nissan plans to restart production of the RB Engine. The RB engine is a direct descendent of the VG-series V6 engine that first became popular in 1983. It offered a modern power range in a straight layout.
RB26
The Nissan RB engine is a straight-6, oversquare 2.0 to 3.0 L gasoline engine. It was produced from 1985 to 2004 and is set to resume production in 2019. The RB engine is a successor to the VG-series V6 engines that Nissan first introduced in 1983. The RB engine offered a modern range of performance in both a straight and V layout.
The Nissan RB26 Engine features an aluminum alloy cylinder block, aluminum pistons, and sodium-filled exhaust valves. It is also fitted with I-beam connecting rods and extra counterweights. The RB26 engine produces enormous power. Its performance can reach up to 206kW. Nissan’s motorsports division has developed special versions of the RB26DETT. The N1 variant was designed for competition in Group A and Group N motorsport. The RB26 engine has also undergone a wide variety of modifications to increase reliability.
The RB26 engine shares many characteristics with the 2JZ engine and has good aftermarket support. The RB26 engine is one of the most popular engines produced in Japan. While factory equipped with 600 horsepower, the engine is not very reliable unless the engine is tuned and serviced properly. It can also benefit from aftermarket parts to reinforce the engine’s internals.
Unlike the 2JZ engine, the Nissan RB26 lacks a variable valve timing system. Variable valve timing changes the intake and exhaust valves at different engine speeds to optimize performance. Variable valve timing can boost horsepower and torque, especially at higher RPMs.
RB30E
The RB30E engine was introduced in 1987 and made its debut in the Nissan Vacationer. The engine was a 3.0-litre inline six-cylinder, four-stroke unit with an alloy cylinder head and single overhead camshaft. It had electronic fuel injection and Electronic Combustion Control System (ECCS) and used a Garrett turbocharger. The RB30E also received some modifications including new pistons and a lower compression ratio than the RB20DE/DET.
The intake manifold is an important component to a successful RB30E tuning project. It conveys air from the air filter into the engine cylinders, and the shape of the manifold has a major impact on power and fuel consumption. Luckily, there are a wide variety of aftermarket options to choose from, and if you want to get the most out of your engine, there are many RB30E performance parts available.
The RB30E is the smallest RB30 engine available. It produces 130 horsepower and is based on a V6 engine. Its cylinder head is made of aluminium alloy. Its intake is comprised of six individual throttle assemblies. It is also available as a two-liter unit with a capacity of 2.6 liters.
RB26DETT
The reliability of RB engines can be enhanced through tuning and general maintenance. By performing minor modifications, an RB26 engine can be tuned to make 400 horsepower or more, which is more than enough power for most users. Regular servicing can also extend the life of an RB26, and aftermarket parts can reinforce the internals of the engine.
The RB26DETT engine has undergone several modifications throughout its history. The cylinder heads, crankshaft, and intake manifold were upgraded. The RB26DETT was first represented in 1989 with a modified Nissan Skyline GT-R R32. It then made its way into the Nissan 300ZX and 350Z sports cars. The RB26DETT engine also found a place in other popular vehicles, such as the Ford Mustang and Infinite G35.
The RB26DETT engine produces 316 horsepower and 289 lb-ft of torque. It weighs 273 kilograms and is capable of holding 4 quarts of oil with a 7W-30 viscosity. It also features six individual throttle bodies mounted on the side of the block in a side-draft carburetor-style arrangement.
The RB26DETT engine also features twin-turbochargers. These boost the engine’s rpm and give it a higher horsepower output. However, these engines are not very common, so the chances of finding one is unlikely. The RB26DETT was initially developed for the Nissan Skyline GT-R, but it went on to power the R33 and R34 GT-R models for more than thirteen years.
RB30DET
The RB30DET engine was a turbocharged version of the RB30 engine. It was a special GM-Holden engine that was made for the Holden VL Commodore. It also found its way into the Nissan R31 Skyline and the Y60 Patrol. The RB30 was a smooth, reliable engine that drove well and got excellent fuel economy. It also came with a four-speed automatic transmission.
Unlike the RB26DETT, the RB30DET is larger and has more displacement. It is usually found in RWD cars, and it is easier to install. However, the bolt pattern of a 4WD car is different from an RB30 engine, so an adapter plate is required for the engine to fit. This plate sits off the gearbox bolt holes.
The RB30DET engine uses an RB30E block and a dual-cam RB25DE head. Using the RB30DET block and head allows owners to gain up to 1500 horsepower. The dual-stage turbocharged engine is also more fuel efficient than the conventional RB30.
The RB30DET engine is one of the few 3.3-litre engines ever built. Despite being an extremely rare engine, it has been used in a purpose-built front engine dragster. Its best 1/4-mile time is 7.26 seconds. Its current goal is to hit six seconds and 200 MPH. Despite its small size, this engine is very powerful and is still among the fastest RB30DET engines.
RB30DET NEO
One of the best aftermarket engines is the RB30DET. This engine is very powerful and gives your car a very strong sound. While the sound isn’t exactly musical, it is very distinct and makes your neighbors’ houses shake. It is one of the most popular aftermarket engines available on the market today.
It was originally designed for the R31 Skyline by Nissan and used by Holden. Holden bought the RB30E engine after their 3.3L Holden 202 engine failed to meet emissions regulations. The original RB30E engine had 153 horsepower and 186lb-ft of torque. Later, Nisan Special Vehicles Division Australia developed a higher-power version of this engine, the GTS2, which was capable of 188hp.
The RB30DET is easier to install and is more powerful than the RB26DETT. However, this engine cannot be installed in a 4WD car as the bolt pattern is different. A special adapter plate needs to be designed and fitted to fit into the 4WD sump, sitting off the gearbox bolt holes.
The RB25DET is a relatively inexpensive engine with a good tuning potential. However, it’s not as good as the RB26, which is more powerful and has a better balance of power. The RB26DETT is the best option if you’re just starting your build. It’s also the most reliable.
RB20DET
The Nissan RB20DET Engine is a 2-liter inline six-cylinder that is easy to maintain and reliable. The RB20DET engine is also relatively inexpensive to purchase and replace, especially compared to other engines. The engine has a robust build quality and a reputation for being rev-happy. However, the RB20DET is also a more difficult model to find replacement parts for, making it a less economical option for some buyers.
The RB20DET is designed with several different components that are essential for engine performance. The cylinder head is a critical part of this engine. Its design influences the amount of fuel mixed with the air. The design of the intake headers has a huge impact on power and torque. It is possible to increase the power of your RB20DET by fitting a big valve kit or port work, and improving your cylinder head flow and compression. However, you should remember that each engine responds differently to camshaft duration and design.
Another part that affects fuel efficiency is the intake manifold. A decently designed intake manifold can increase your car’s fuel efficiency significantly. You can also improve your vehicle’s performance by installing a front-mounted intercooler. This can reduce the intake temperatures and bring back some power lost due to heat soak. A turbocharger upgrade is a great option for improving your RB20DET’s performance, and a front-mounted intercooler will greatly increase the amount of air flowing through the engine.
