I find most of the holdens a bit sloppy feeling but that may just be me. Though the the R34 is only a 2.5ltr DOHC (4 vavles) with VCT it seems to go ok. Best thing is to take one for a drive I'd say
Some specs
NEO RB25DET - twin-cam turbo (206 kW (280 PS) @ 6400 rpm, 362 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. 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).
