2000

Lets just say I made a custom one and it didn't work out with my ecu etc...car runs like crap, but seems faster & sounds great haha. (it's much too large @ 3") I just want my good gas mileage back and my car to run somewhat normal haha. Please help!! I NEED THE FULL PIPING AS WELL AS THE FILTER...

Hey guyz so i have a 00 protege 1.6 5 speed & i want a lil more power. Im gettin ready to rebuild my motor and put new gaskets, & chamge clutch since im already at 130k miles. So i decided i might as well put better internals. Problem is i cant find anythin for this motor no pistons, rods, cams...

My friends looking for a car and I'd like to introduce him into the mazda family. He has 2000$ to spend, cash of course. Mods and speed are not important, just looking for a reliable car to get him to work and school every day. Looking for something in the tri-state area, but We'd be willing to...
