Hi, I am planning on doing some modifications to my engine, I have an 05 toyota corolla, it sucks!!, I wan't to make it a lot faster... I am planning on buying a cold air intake, a header and exhaust...but just to be sure.. I was hoping to get some advice about what should I do first.

well i think dat u should go for the intake first.cuz it's the first thing to put when u are planning on boosting a car.

hi i'm an engiine preparatur if you want te make faster your car this is what you have to do install a turbo it will give to your car 100-120 hp +to your car but dont forget with this power youshould change also the distribution also if you remove the filters from the exoust an remove the thermostatand use a 15w-55 oil you will have 20 hp more

first you need to advise us on what engine your rolling with and you need to know that if you modifi your engine your going to need to modifi your brakes first, apart from that you cant go wrong with thous up grades.
