my wife and i just bought our hatches. both hatches are 91 dxs. one is an auto and the other is a 5 spd. The only down side is these things are slow. my wife wants more power just to keep up on hills and i want more just to have more. i plan on going throught the supension and adding tein coilovers and some 15 in wheels, i want the cars to be identical with the only difference beint the fact that mine is a 5spd and hers is an auto. what engines would you recomend?
