whaddaya mean a charged engine is less efficient and have higher fc then an na? the turbine was hooked on airplanes, cars, generators and god-knows-what-else to make them more efficient, to consume less fuel while providing more power at the same time, without having complicated/advanced technology behind it. complicated/advanced technology means higher maintenance, more expensive parts, etc.
my 1.3liter charged engine consumes less fuel then my previous 1liter na, if driven sensibly.. but lets be honest, with dat amount of pulling power and being a frugal economy type engine from toyota; good fc even when pushed hard, wud u drive it "sensibly"? LOL
i actually have both na and charged cars, but if i have to choose between the two, i will choose charged cars hands down for their phenomenal pull, no-drama-take-over capability, easier to upgrade/power-up, less complicated then most na machines these days, and many2 more reasons.
