so I'm pretty new hear and I have no idea where anything is and I don't have the slightest clue on where to start modding.

I have a 92 oldsmobile cutlass ciera
I love this car and making it look better and run better and get better mpg is what I like

I plan on removing the AC, compressor, and condensers from the car but I can't find squat on how to do said removal.need some help there lol

I'm removing the carpeting out of my trunk and I found that the trunk hood has a second layer of metal idk if I should remove that or not, idk if even can.

I've been trying to find these mods for my car, but all the sites I see I'm wary about but you guys can point me in the right direction of where to buy.
I'm looking for these parts for my car:

Carbon fiber hood
aluminum rims
racing seats
fuel cell(along with corresponding parts)
lighter coilovers and shocks
after market ECU that manages mpg better
better/lighter exhaust pipes

anything else I left out
