get a trd supercharger... thats probably the biggest (and safest) part to gain hp... there is little things like a cai... but face it... its a corolla... i bought one bc it gets good gas mileage (i put like 40000 miles on it the first year so i know) it wasnt made to go fast... if you want a car...
hell yea its a good car... when i was 16 i got a 95 integra 4 dr.... that thing would overheat and all kinds of crap... i would have loved to have that camry instead....
