Ok here we go. I just bought a white Pontiac Grand AM GT with a 2.4L 4 cylinder with a manual transmission. The car is my first, and i just turned 16. I am also an enthusiast and i plan to be an automotive engineer. I have driven the car for a week. The engine is a strong 150hp but i want about 200 as well as a better tranny. Im looking for information about the best quality products for a slight buildup. I also need information about suspension part like adjustable shocks and anti roll bars. Also the sound system needs some help. Also anybody know a good place to get 205/55 16 tires for cheaper then a hundred a piece. Any information is appreciated.

To get a little bit more hp i suggest getting it chiped and maybe getting the cams done depending on how far you want to go
