I could stare for hours to this Nissan RB26DETT cutaway drawing and still not see every detail in it!
The black valve cover on this Nissan RB26DETT uncovers this engine as a R32 or R33 type and as the cutaway drawings got out of fashion in the 90s the drawing is probably made around the launch of the BNR32 in 1989.
The Nissan RB26DETT is/was one of the most awesome engines that Nissan made. The engine is an cast iron block with aluminum head, has 24 valves with double overhead cam, a parallel twin-turbo setup and six individual throttle bodies. Even though the initial power was “only” 280ps (276hp) the engine is able to output more than 1 megawatt (1,340 hp) after heavy modifications. I would say it is a good successor of the Nissan S20
