take it from a corolla nut that performace wise it is hard to come by. A good place to start is monkeywrench.com I believe is the site. The thing about corolla's is no one expects us to have anything, which is great because there jaw drops even lower when we kick there ass.
for corolla got 9thgencorolla.com or corollacarclub.com (there is a guy with a 1zzfe 2001 turbo corolla that loves kicking lexus and honda ass) as well ass vvt-i.net
By the way, there is a corolla with 650 horsepower without NOS, how is that for big ballz under the hood.
