Nissan RB Engine
The RB engine is a 2.0L to 3.0L straight-6 piston engine from Nissan.
It has an aluminum head with both SOHC/DOHC versions, with the SOHC versions having 2 valves per cylinder and the DOHC versions having 4 valves per cylinder, all cam lobes move only one valve. All RB engines have belt driven cams and a cast iron block. All turbo models have an intercooled turbo (except the single cam engines RB20ET & RB30ET), and most have a recirculating factory blow off valve (except when fitted to Laurels and Cefiros) to reduce boost surge when the throttle is closed. In common with all Nissan engines, D indicates DOHC, E indicates EFI, T indicates Turbo.
From August 1993 RB engines produced also featured NVCS (Nissan Variable Cam System) for the intake cam.
From 1998 the RB25DE/T series was released with a 'NEO' head, which enabled the engine to be classed as an 'LEV' (Low Emission Vehicle). The 'NEO' head improved the torque and power of all engines in which it featured, although the RB26DETT still only produced 280 PS (206kW) according to Nissan factory specifications. In reality, it developed more than this due to all main Japanese car manufacturers having to adhere with a 'gentlemen's agreement', which specifies that a manufactured vehicle should not be advertised with an engine exceeding 206 kW.
The 'RB' name stands for 'Race Bred'. :regular_smile:
