Putting the car on a diet
I like your idea!
Get an all aluminum slant 6 for it with aluminum intake and tube header with single exhaust (no tail pipe), aluminum pulleys, mini starter, Denso alt, aluminum radiator with fiberglass flex fan, pin on fiberglass hood, fiberglass bumpers, fenders and doors (carbon fiber if you can afford it would be better), tubular front end components, lexan windows, aluminum dash, and as many brackets as you can find with aluminum, remove any wiring that you don't absolutely need, replace all bolts with titanium, break out the hole saw and drill bits and swiss cheese all of the structure you can reach, lightweight bucket seats, smallest tires on the lightest 14'' aluminum wheels you can find, 904 automatic, carbon fiber drive shaft, 7 1/4'' rear end with 2:21 gears, heater and radio delete, standard steering, standard brakes with aluminum master cyl, lightweight Willwood disc brakes front and rear, no undercoating or carpet insulation, lightweight battery, 5 gallon fuel cell, no spare tire and wheel or jack and tools, the lightest steering wheel and column you can find, find the lightest windshield wipers and motor from a newer car, leave the windshield washer system as is, remove two lug nuts out of five on each wheel, remove 2 of the 4 headlights, remove undercoating, acid dip the body and paint the car with one coat of paint.
I hope this helps.
