I've always been a Honda person, wife wanted 4wd/awd but not an SUV. So I recently picked up a new 2006 Matrix Xr 4wd. You can't beat the value of this car and it's bigger than any Subaru in the price range. We're gonna throw a baby seat back there one day

(my fault I know...), but for now I have up to $1K and was wondering what recommendations you would suggest to increase low/mid end power. I'd like to improve my 0-60 times. I've read a little about CAIs, chips, exhausts, lighter pulleys, etc. but I'm looking for best bank for the buck at this point. Thanks.
