tacoma pull a part regularly has available parts for both of those cars. i love my loyale but id love to have a justy.........you could always put a 13b in that beezy and haul the mail or keep the rpms low and save gas. or, drive the 3 cyl and destroy gas mileage.
bottom line: if its strictly for commuting, justy. if your gonna use it for anything else, go ea82 and tune up/t belts
