ya both gst and gsx has the same power as 210 hp stock... and yes gst and gsx are the same car except gsx has all wheel drive.. all gsx are leather interior with power seats ( leather is optional in gst and they dont have power driver seat)...both gst and gsx are turbo charged and have the same engine 4h63T.... the RS and GS are not turbo charged.... gsx is good for drag racing and handling... gsx is also good for any race from the stop
whereas the gst is good for highway racing (illegal) and for any races from the roll .. hope this helps
