Nissan RB Engine - RB24S

RB24S

This is a very rare engine, as it was not produced for the Japanese domestic market. These were fitted to some left hand drive Nissan Cefiros exported from Japan new. Mechanically, the RB24S combines an RB30E head, RB25DE/DET block and RB20DE/DET crank with 34 mm height pistons. The resulting 86.0 mm bore and 69.7 mm stroke combined to form a 2,428 cc inline-six engine.

This engine used carburettors instead of the Nissan ECCS fuel injection system. It is able to rev harder than the RB25DE/DET (as it has the same stroke as the RB20DE/DET) as well as being almost the same displacement as the RB25DE/DET. A common modification is to fit a twin cam head from other RB series motors while retaining the carburettor set-up. The standard single cam form produced 141 PS at 5,000 rpm and 20.1 kgf·m (197 N·m) of torque at 3,000 rpm.
