Ok. Tonight, I was driving home from hanging out with my friends and this SRT-4 pulls up beside me. I wanted to race him just to see how I would do up against one so I did. Turns out this wasn't an ordinary SRT-4. That thing hauled ass. When I got a chance to talk to the driver, he said that he upgraded to a much bigger turbo than the stock one and drove away. That did it. So now, I want to know what turbo and engine upgrade I should go with to make some crazy HP. Help me out people.
