Engine Nissan RB26DETT

Engine Nissan RB26DETT

The RB26DETT engine (or RB26 for short) was installed mainly on the Nissan Skyline GT-R in the body of R32, R33 and R34, Nissan Stagea 260RS. This engine was developed in the Nismo division for the Skyline R32 GT-R car racing. The engine has a high potential to increase its power, thanks to which RB26DETT gained worldwide fame.

The timing mechanism is driven by a toothed belt. The RB26DETT intake system, unlike other RB series engines, has 6 throttle assemblies instead of one (one throttle valve for each cylinder). The engine is equipped with two turbochargers (T28 ceramic turbines). Such a system is called parallel turbocharging or Twin Turbo.

Explanation of Nissan RB26DETT markings

Engine Nissan RB26DETT under the hoodNissan uses a consistent method of marking its engines and the RB26DETT engine is no exception. The first letters in the designation define the engine series. The numbers indicate the volume of the combustion chamber in deciliters. The following letters indicate the different types of functions.

RB Engine Series (R-Line)
26 Engine displacement, l x10
D The cylinder head has 4 valves per cylinder
E Multipoint (Distributed) Electronic Fuel Injection
TT The engine is equipped with two turbochargers (TWIN TURBO)

Engine Features

  • Lack of hydraulic valve lifters. Rigid pushers are used instead. The valves are adjusted by the selection of washers.
  • The original design of the intake system, in the throttle assembly of which 6 throttle valves (one for each cylinder) with a diameter of 45 mm are installed.
  • Lack of electronically controlled variable valve timing system. Camshafts are used with parameters: phase – 240/236 mm, lift – 8.58 / 8.28 mm. The timing mechanism (timing) is driven by a toothed belt.
  • The design of the cylinder block in which there is no oil channel.
