I am not sure how much "show" you want to do but here are some ideas. First would be new tails swap to something nice like s2k's but NO supra's. Full body kit molded in with some fender flares or widebody the car. your interior will be fine with what your getting from keith just maybe add some subs in a fiberglass box and maybe a nitrous bottle for show possibly even a back half roll cage for the "race" look. The engine bay will be the hardest I am not sure how bad yours is (I have some rust and stuff like that in mine) but chrome or powder coat evererything. Big rims 18+ the 17's will do but the more body work you do the worse they will look. Thats all I can think of right now good luck. EDIT shave it including handles, door caps, antenna, rear wiper etc......
