i have a 2005 mazda 3s with a 2.3 L. i have put a magnaflow cat back exhaust and a aem intake on it. just looking to see if there is anything else i can put in the motor/transmission to squeeze more power out of it, short of turboing it. any help will be appreciated.

 

nice dude, i have an 04 mazda 3, 2.3 l. i only have an hps cai, but i'm savin up for a turbo kit from ebay for about 1800, i suggest that if you want to get a turbo that you save up for it get it installed then get it chipped. you should be pushin some extreme power then.

 

clutch kit. (manual only, obviously)
sprint booster. (for the AT crowd)
lightweight pulleys.
racing header.
voltage stabilizer w/ groundwire kit. (this ones def up for debate)
stage 1 weight redux.
smaller, lighter rims.
ECU upgrades.

many options available, but the real results come from turbos and superchargers.
