Whats up everyone. I just recently purchased an 03 vw jetta v4 2.0, automatic. Its not that fast of a car and only tops out at about 90mph or so. Is there any possible way I would be able to upgrade it to make it faster. I was thinking of an exhaust system or turbo. Im not making too much money niether so im searching for an affordable way I could make my car faster. Any suggestions ??
