wanna know bout mpg if adding aturbo

if u put in a turbo from like alpine den about how much would ur miles per gallon be??

cuz i was jus looking at a mitsu eclipse gsx and it does 20-28 gallons.

What kind of Turbo?
How much boost?

etc etc

it depends on how hard you push your car... ie: how heavy your foot is...

if you get a turbo, you will need to be burning more fuel. you will get less gas mileage.
