Looks like I have beaten Porsche to the punch!
Check out my all alluminum Supercharged :P LS1 V8 porsche 911.
My engine is 75 pounds lighter than the stock Porsche 3.0L motor.
Well, I don't think that this will ruin the "spirit" of Porsche, after all, this will still be one of the world's premiere sports cars. The only thing that I wonder about is how a rear engined 911 with a big V-8 can maintain its legendary handling capabilities. Then again, the Porsche engineering staff is among the finest in the world.
