i recently purchased a 2007 mazda3 touring with the 2.3L engine. i want more performance without having to spend 5k ona turbo or void my warranty. i need some suggestions on wat performance mods i should make. i'm already planning on buying a typhoon intake and some type of bolt on exhaust. any suggestions would b greatly appreciated.

 

thats pretty much all you can do without voiding the warranty. And with those, should you be real concerned about the warranty i would get mazdaspeed intake and exhaust.

If you are looking for suspension and handling then you can go springs, struts, shocks, etc... They can still void your warranty though if something suspesnion related is broken.

 

so basically all i can get is about 10-15 more hp out of my car wihtout voiding the warranty?....damn....

 

yupp.... pretty ****ty eh?
you can do header's back exhaust, and an intake.
then some lighter wheels....
oh, and if your car is standard, get a lightweight flywheel.
everything else we do to our 3's are suspension mods, and then appearance mods.... ie, wheels, open mouth grill, lips, spoilers, etc etc
