i bought a 1990 celica ST for $700 and so far ive done new tires, tags, exhaust, steering wheel, and painted the hood, trunk and roof black and so far i love this car! it turns very good, gets perfect gas milage, its the best car for a teenager, plus its a toyota and easy to work on! anyways i have a few questions, 1st is my friend and i advanced the timing from 10 to 11/12 and i wanted to know if that would do any damage to anything? has anybody put a cold air intake on theirs and noticed a difference? where should i look for sway bars/ strut bars? or any other performance parts for this car? thanks!
