context_page_description: The RB engine is a 2.0–3.0 L straight-6 four-stroke gasoline engine from Nissan, produced from 1985 to 2004, and will be continuing production in 2019, after a 15 year hiatus. The RB followed the 1983 VG-series V6 engines to offer a full, modern range in both straight or vee layouts.
  Both SOHC and DOHC versions have an aluminium head. The SOHC versions have 2 valves per cylinder and the DOHC versions have 4 valves per cylinder; each cam lobe moves only one valve. All RB engines have belt driven cams and a cast iron block. Most turbo models have an intercooled turbo, and most have a recirculating factory blow off valve to reduce compressor surge when the throttle quickly closes. The Nissan RB Engine is derived from the six cylinder Nissan L20A engine which has the same bore and stroke as the RB20. All RB engines were made in Yokohama, Japan where the new VR38DETT is now made. Some RB engines were rebuilt by Nissan's NISMO division at the Omori Factory in Tokyo as well. All Z-Tune Skylines were rebuilt at the Omori Factory.
context_section_description: The first RB20ET/DE/DET engines were fitted to the HR31 Skyline and the Nissan Fairlady 200ZR (Z31 chassis), produced from August 1985. The early twin cam engines featured the NICS (Nissan Induction Control System) injection system, while the later twin cam engines used ECCS (Electronic Concentrated Control System). Later versions which used ECCS engine management, discarded the twelve tiny runners for six much larger ones (though they retained twelve ports on the head, so there was a splitter plate). It was also fitted to the A31 Cefiro, C32 and C33 Laurel. The Fairlady 200ZR was fitted with an intercooled NICS type RB20DET.
  The first RB20E engine was used in the C32 Nissan Laurel, produced from October 1984.
  Laurels, R32 Skyline and Cefiros used the second (1989–1993) series RB20E/DE/DET. This had an improved head design, and used the ECCS injection system. These later motors are known as "Silver Top" engines.
  The RB20DET-R was used in the Nissan Skyline 2000GTS-R (HR31) and was limited to 800 units.
