okai i've got some engine and now some extra weight, due ot my winter break project (new custom sub box), so im thinkin of what i could lose to lighten the car up a bit, maybe 100-200 quick lb's any suggestions

 

You could ditch the stereo...

Also the back seats, spare tire and jack, carpet padding, console, shave off all the "****" under the carpet, add some lightweight rims and tires, fiberglass body parts also help, get a lightweight battery and relocate it to the trunk area...

It all depends on your goal and how much you are willing to sacrifice.
