Pictures of the RB Series Engines
The Purpose of this page is to give you a visual inage of the RB Series Engines as they look installed in the different model cars that Nissan produced.
RB20DE - Left
Visually similar to the RB 20 DE engine, with almost no obvious differences. The car build plate, located on the right hand side of the fire wall, by the brake booster in RHD cars, will have the engine identification.
If the engine is not in the car, the only reliable way of determining whether the engine is the 2.5 liter is to check the engine type which is stamped on the block at the left rear of the engine- see the RB20 HKS picture below.
In the Skyline, the intercooler is located on the left hand side of the car, below the front bumper.
Note: Japanese sourced engine computers will have built in electronic speed control to limit vehicle speed to 180Km/hr (112 mph), if the speed sensor input is used. The speed limit is set by a value in ROM.
Obvious by the "RB26" label in the front timing cover. Normally a grey color like the RB 20 & RB 25 engines, this engine has been painted and modified.
The intercooler is much larger, and is mounted in the front centre of the car.
