Need help with weight reduction
 

I need help, i have a 92 accord EX 4Dr with a 96 prelude V-Tech 2.2L engine, already got a cold air intake, a spoon chipped P13 ecu, high conductive Tsudo 9.5MM Plug Wires, and full custom 2" egxhaust with high flow cat n Muffler tip, just put Eibach Pro-Kit lowering springs, did a 1.5" drop front/rear, and i figured, ok, if I dont have much money to put into the engine, why put more horsepower off from the engine when i can work with what I got, any tips of any tweaks would be helpful, but im mostly looking if anyone knows if theres any weights or whatever can reduce the weight of the car, like things that are not necessarliy needed for the car to work/drive properly, I figure weight reduction you can get more out of what you already got, thank you....
