forget the R32
the R33 that followed was built as a much much better car than the R32 even though they are a heavier car a few cheap suspension mods will improve its handling ten fold.
the RB25DET is a ripper with loads more torque throughout the rev range and a smoother power delivery. The engine is 500cc bigger, has a higher compression ratio 9.0.1, variable valve timing on the intake, and a higher flowing head. The Turbo and intercooler are also slightly larger. its basically a better car. and cheap mods make them fairly quick. straight line 0-100 speed is excellent my R33 on my gtech did a 0-100 in 4.9 seconds on a fairly flat surface with only ~205kw standard turbo semi's on the rear.
simple bolt ons and a cheap remapped ECU gave me a 50% power increase over standard.
