5th place for RB25DET

TheRB25 engine line might not be the best performance engine that Nissan had but it is widely available and easier to find than it's bigger brother the RB26 line. It's very popular and it can even fit in a 240sx!

The 2.5 L RB25 engine was produced in four forms: RB25DE - NON-TURBO twin-cam 140 kW/190 PS (180 - 200 hp ) @ 6000 rpm, 255 N·m (26.0 kgf·m) @ 4000 rpm) RB25DET - twin-cam TURBO (T3 Turbo) (245 to 250 hp and 319 N·m) RB25DE NEO- NON-TURBO twin-cam 147 kW/200 PS @ 6000 rpm, 255 N·m (26.0 kgf·m) @ 4000 rpm) RB25DET NEO - twin-cam TURBO (206 kW (280 PS) @ 6400 rpm, 262 N·m (37.0 kgf·m) @ 3200 rpm) RB25DE and DET engines produced from August 1993 also featured NVCS (Nissan Variable Cam System) for the intake cam. One of the best engine for cars (tuned) is RB25DET. (2020 concept cars)

This gave the new RB25DE more power and torque at lower rpm than the previous model. From 1995,(Series 2 Engines) both the RB25DE and RB25DET had a revised electrical system and the turbocharger on the RB25DET(S2) had a ceramic compressor wheel rather than aluminium.

The most obvious change to the system was the introduction of ignition coils with built in ignitors, therefore the coil ignitor that was on previous models was not used.

In May 1998 a NEO head was fitted, which enabled the engine to be classified as a low emission vehicle (LEV) engine due to their lower fuel consumption and emission output. The non-VCT, non-turbo RB25DE was fitted to 2 door sports cars like Nissan GTR32, the VCT turbo and non-turbo was fitted to R33 Skylines and the 1996 nissan stagea.

Early R34 Nissan GTR use the non-NEO RB, later Skyline and Stagea (WGNC34) models use the NEO version.
