NISSAN SKYLINE RB26DET ENGINE

The RB26DETT family of engines powered quite a few iconic cars. From R32 to R34 GT-Rs, Nissan’s idea of an inline-six powerhouse was a treat for enthusiasts and tuners alike. The RB26 was a derivative of the RB25 that equipped the Skyline GT-S.

Often considered to be an engineering marvel, the RB26, much like the 2JZ, is known for its durability as well as for being purposefully over-engineered.

The RB26 engine was introduced in 1989 and had its run until 2002. A derivative of the RB25DET, this engine, unlike its predecessor, utilizes a cylinder block with no oil port. It features an inline-six layout with a cylinder bore of 86.9 mm, piston stroke of 73.7 mm, and a compression ratio of 8.5.

Contrary to what many believe, the name RB is not “Rhythm and Balance” or “Race Bred”, it’s simply the engine series. The 26DETT stands for “2600-cc DOHC Electronic Twin Turbo”.

All RB series engines, including the RB26DETT, are interference engines manufactured in Yokohama, Japan. Nissan made use of the RB26 in R32 and R33 Skyline GT-Rs, while a reworked version of the engine was used in the R34. Yeah, all of these epic Skylines were more or less banned from the USA.
