how much money do they invest to make cars perform better?

[youdontknow]

these type of cars...civics...with little v4 engines! how much money would they put in it to make it peform as a good as a mustang (gt), trans am, or infinit g35 something that is meant for racing....would you spend alot less money and get just as good performance in a car? or would it just maybe be faster....I don't care that much for speed as long as its not slow....I mean after you put a turbocharger on that civic or something or a supercharger etc...to the point where you made it fast....it really wouldn't save you that much money on gas anywhere right even if it is a v4 ...I have nothing against hondas...there reliable cars and get good gas mileage..but it does look lame on the streeet when it sounds like a lawnmower and if its like a hatchback it looks funny....looks like fast and the furious wannabes that is so old already

Some guys have over 100K dollars invested in their tuners. These are the show and go cars and rarely seen on the street. A more reasonable figure would be 5 to 10K.
