i have a 05 tc and i want to stay N/A. What all can i do to her without spending thousands of dollars???
the only thing ive done so far is a cold air intake and...........yea thats it!  

Unfortunately in this industry it takes thousands of dollars to achieve some minimal gains. Even with bolt-ons you'll pass the 1,500 dollar mark and only gain about 10-15hp average... It is only the committed who get somewhere or the insane

But the best way to go about it is to be the most savvy and efficient, tech and money wise.


This guys did it about right, not too much and not to little and it pumps out about 230hp with a few bolt-ons and it can handle decently to keep up with a Porsche on the track.

most of this stuff can be done in a weekend or two depending on skill... Those cars are a good platform. Just be patient and keep at it until you're done and good luck...
