well, mine weights 2885 with between 1/4 and 1/2 a tank of gas, me out. I have big brakes, a water injection pump and a cast iron manifold. As well, a steel hood, stock wheels, stock front seats, power windows, power locks, power steering, rear wiper, sunroof, both stock heavy steel bumper re-bars, a fairly heavy intercooler, a cast iron transfercase, both balance shafts, stock steel pulleys,full interior seats forward and a stock steel tube 3 piece driveshaft.
Put in a carbon fiber hood(25lbs saved, light wheels(20lbs saved),1 race seat(60lbs saved)manual windows and locks, rear wiper(10lbs saved)manual steering and no sunroof(25lbs saved), light bumper rebars(75lbs saved)lighter intercooler(10lbs saved)half aluminum tcase(10lbs saved), balance shafts removed(25lbs saved), cf or aluminum driveshaft (15lbs saved), and light weight pulleys(10lbs saved). Tubular exhaust manifold or FP cast manifold(20lbs) FP cast exhaust housing for the turbo(5lbs)
That adds up to 310 lbs from my car.
Now, I could get crazier, gut the rest of the interior(dash, door panels, center console, carpeting, scrape all the sound deadener, cut some of the sheet metal out that is just to hold in the interior panels, head liner etc) and I'd say that would be at least another (100 lbs). Then, carbon fiber doors and front fenders(150lbs), no rear spoiler/side spoilers,(25lbs), lexan glass all the way around(300lbs). Short, almost downpipe only exhaust(75lbs) Standalone EMS with only enough wires to run the engine, fan and the lights,(no maf, no complicated wires, no extra crap at all) Probably save another (20lbs) Convert to a 1gb front end(20lbs), no ABS at all(20lbs) Convert to a 1 wiper system from a Scirrocco(5lbs), no washer bottles front or rear(5lbs full), small, billet alternator(5lbs), light racing starter(10lbs), slimline racing fan(2lbs), no hood prop rod or rear hatch struts(2lbs), custom light weight K member availiable on 'Tuners(35lbs)
Now thats a total of 774lbs.
Now of course you could build your engine with aluminum rods, and bore it out 040 over(replace cast iron with aluminum), this might net you another 10lbs too.
Oh, I could take out cruise control too, for another pound or 2. With a bit more nit picking, I could get that 774 to 800 I'm sure. Eg, light weight lug nuts. Oh, hell, I forgot aluminum calipers and 2 piece (aluminum hat) rotors. That would bring it over that for damn sure. Especially if you did all 4 wheels. Maybe someone makes light control arms? Another 2-3 lbs per(10lbs)
So add the conservative 815 lbs to the conservative 310, and you get over 1125 lbs taken off my cars already less than stock weight car! This would take my car down to an anemic 1760 lbs or less!! And this car would still be street legal, and be driveable with a heater, wiper, lights, signals and a comfortable seat, with tons of cargo space. No, not quiet, not smooth, not a pleasant commuter or hiway car, but no where near like an all out race car.
So you can see that 2700 would be real real easy!! Nearly 1000 full lbs more in your car when it hits 2700.
And even if you put in a quality roll cage, you would still be under 2000 lbs. Then all you'd need would be a real reliable, well tuned 400 hp and that car would be stupidly fast. And easy to work on. And get better mileage. And stop better. And if the suspension was set up properly for the correct corner weights it would handle better too. Hell, I bet even with another seat in it, the thing would still weight under 2 grand if you were smart about a few things.
