My project started out as a 283 V8/2 speed auto, 2 door Malibu. I weighed it with very little fuel in it prior to tear down and it weighed 3,172 lbs.
I bought an all aluminum 3.8L/220 CI V6 and a 6 speed double overdrive automatic transmission from a 2013 Camaro. The Camaro shows that it weighs approx 3,850 lbs. I never got to weigh the actual doner car.
My goal is to bring the finished project in at around 2,850 lbs. The new engine/trans is a lot lighter then the old iron V8, I have added lighter suspension and brakes, will use lighter weight seats, aluminum radiator, aluminum wheels, fiberglass hood, etc. I don't think the 2,850 lbs will be tough to reach.
The Camaro's EPA rating on the highway was 30 MPG. I believe that my car being approx. 1000 lbs lighter, lowered 2" from stock, a front air dam, and whatever other tweaks I can add, 35 MPG is a realistic goal.
What do you guys think?
