How can I make my 2008 Mitsubishi Eclipse GS faster?

Well, it is just a car, you make it faster in exactly the same way yo do it with other cars, its just physics.

The first think you need to do is setup a budget otherwise I would recommend a Turbo Kit for around $5000 USD, if you are on a limited budget maybe a camshaft will do the job, you can use a car performance simulator to virtually try different tuning options and run tests to see how the car improves, you can find it at http://www.nxgtrsim.com/

Yeah, this about sums up 75% of the questions asked in this section of Yahoo answers.

How about you start by not buying a 3500 pound boat with an inadequate four cylinder?

I have hit one hundred forty in mine, however the trader stated it might pass each and every little bit of the speedometer... and thats a hundred and sixty. So all I can say is purchase it and take a look at it! Warning, the climb after one hundred thirty five is slightly lengthy...

Sell it and buy a 1996 volvo 850 turbo and make $$ and buy a racing chip and better exhaust for it

money=parts=hp=faster

Rear end it with a bus.
