looks like E46 318i 1.9L recond unit, am i right? what do u mean by changing engine bay? changing engine to 2.5L? or adding extra performance kit such as gruppeM or K&N open filter? or stuff a mickey mouse inbetween the engine gap to look more compact?
Think u better change to JDM.. then can go change like you want... comparitifly chip chip some more! Can put butterfly rainbow color somemore... choose pink, yellow, blue...ehehehehehehheh
