I have a 2001 Chevy Tracker 2.0 Liter 4 Cylinder. It has around 120 horsepower.

I will be upgrading it to some sort of 6 or 8 cylinder engine and will bring it to around 400 some or 500 horsepower.

Who else is doing a fixup project on their vehicle?

well, the closest I can say is that my father spent a few minutes checking the underside of my mother's car, after she hit a paper recycling bin thingy on the highway...

Haha, that is always fun though
