okey.. put B8 turbo enjin.. stock setup will get you around 146hp.. from there, a little upgrade there, a little performance part here.. without changing the turbine you can get around 200hp.. with proper boost level and enough fuelling, of course.. shud be enough to play around with other similar class cars..
but then, on the road, a lof of other factors will also contribute.. launching, tyre, gearbox ratio, etc etc..
