well i just finish aguring with my friend, cause he said that the si comes supercharged.. i told i build one on the site and i never saw that option and that he said that theres a couple of them riding around with a supercharger.. so my question to you guy and girls is, " Does the 06 SI comes supercharged and if it is a option or not?" i just want to prove to mu friend that it doesnt unless you guys prove me wrong..
