Quote »Nissan RB engineThe RB engine is a 2.0 L to 3.0 L straight-6 piston engine from Nissan. It is an aluminum and cast iron DOHC 4-valve per cylinder design. All RB engines have belt driven cams. All turbo models have an intercooled turbo and recirculating factory blow off valve to relive turbo boost when the throttle is closed. All are twin cam except the single cam 2 L RB20E and 3 L RB30E engine.
From 1998 the RB series (except the RB20E and RB30E, as they were discontinued) was released with a "NEO" head. This enabled the engine to be classed as a LEV (low emission vehicle) engine. With the NEO head, torque and power were further improved although the RB26DETT produced still only 205.94 kW on paper, according to Nissan specs. In reality it produces more than this but it is under estimated because all main Japanese car manufacturers have gentlemen's agreement not to produce cars with engines exceeding 206 kW.
The "RB" name is thought to represent "rhythm & balance", or "race bred". As yet, there is no official word on the naming convention.[/quote]
