take everything out of your interior, remove the p/s, a/c, radio, spare tire, jack, take the body off and sand down the panels to half there present size, repaint with one coat of spray paint (lighter than the stuff on it now), remove hub caps, remove hood, trunk lid, remove power units (windows-mirrors), remove intake, remove muffler, remove exesive plastic from around engine bay, and... run around at 1/8 a tank of gas all the time. Im sure you would drop a second in the 1/4 with all that. Not going to say the car will last a long time.
On a serious note, you could do the TB-Coolant Bypass and the Slave Cylinder Mod. And you could remove the weather stripping at the back of your hood to promote a slightly cooler engine bay. Let's not forget removing the Air Intake Resonator!
