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)
