i am thinking that would RB25DET is easier to mod for extra power than SR20DET due it has a six cilyder and bigger engine, right ??
another point is, decreasing GTT weight is much cheaper way to mod than increasing S15 power, is that right ?
by the way, WRX will not be included in consideration, because its very smart 4wd system will hide human error,and kill or stop my driving skill from growing! and by its 4wd nature, wrx is not born to suit high speed, right? i have heard that drive a little FR is always a good way to start practise, am i right?
