It varies by the model of course
A GTS1 does 0-100 in about 9.2 seconds, and a GTS2 does it in 8.8 seconds, though I reckon both have to be quicker than that, because a run of the mill manual sedan can pull about 9.4 or 9.5 seconds
For power, australian R31 RB30E engine makes 114kw, GTS1 makes 130kw, GTS2 makes 140kw.
Imports have a couple of different engines, RB20 and RB30
RB20s come in single cam and twin cam, non turbo and turbo, and different variants of each.
Power ranges from around 100kw to around 150kw depending on the model & spec
