How can I make my Mazda 3 faster?
 

anybody knows what parts i need to make it faster?

Id first start with a cold air intake :) K&N or AEM

Where can I find it? Then what should I get after that?

well i usually buy my parts off of ebay. sencond thing id do would to get a cat-back exhaust system. then maybe look into headers :)

id go with fujita f5 for the cold air intake, then geta header and cat back exhaust.. if you ahve the money you can just go with a turbo kit and build the internals and have a really fast 3 :)

Cold Air intake ( about 5-10 HP in that car), Exaust will cost you 7-800 and not getyou more than 8 HP. That engine could be tuned or chipped, that is the the easiest way t boost it without Turbocharging it. Check ebay or the Mazda3 message boards for some Speed3 turbos. People upgrade them and sell the old ones for a couple hundred bucks

yeah, but buying a speed3 turbo would be pointless on a regular 3 because then you would have to make/find the other components... (turbo manifold, intercooler piping ,etc.) and it wouldnt be as efficient, its easier to buy a turbo kit that is already made for a 3 than to try and make one from basically nothing using a used speed3 turbo.. you could even use pieces of different turbo kits to make you own kit
