for the past couple of months i have been contemplating boost. And i have a couple of questions...

1.) what do u guys do about the two o2 sensors?

2.) am i better buying a kit and what brand is the best in your opinion?

3.) am i better building it my self, what parts or turbo works the best?

Im looking to keep pretty much stock internal and just want more power, this is a daily driver and im off to school in a year so i need a reliable car.

i understand i sound like a noob but any help is greatly appreciated
