RB25 Information

RB25DE and DET engines produced from August 1993 also featured NVCS (Nissan Variable Cam System) for the intake cam. This gave the new RB25DE more power and torque at lower rpm than the previous model.

In May 1998 a NEO head was fitted, which enabled the engine to be classified as a low emission vehicle engine (LEV). The non-VCT and non-turbo was fitted to the R32 Skyline, the VCT turbo and non-turbo was fitted to R33 Skylines and the WC34 Stagea. R34 Skylines also use these engines, but they are fitted with a NEO head.

The 2.5 L RB25 engine was produced in three forms:

• RB25DE - NON - TURBO twin-cam 140 kW/190 PS and 147 kW/200 PS (with VCT) @ 6000 rpm, 255 N·m (26.0 kgf·m) @ 4000 rpm)
• RB25DET - twin-cam turbo (T28 Turbo) (245 to 250 hp and 319 N·m)
• NEO RB25DET - twin-cam turbo (206 kW (280 PS) @ 6400 rpm, 362 N·m (37.0 kgf·m) @ 3200 rpm)
