i bought the 2.5 auto fully intending to swap the drivetrain from my wrecked 1989 reatta.67 hp increase.but everyone says don't do it.i can't even find a how to on it.the fieros only getting 20.1 mpg city.and that's mostly 35 mph.the reatta got around 18.i see mount kits for series one engines so i emailed them to see if that would work for a 1989 3.8.no response.
