Everything you need to know is on this site. I've been reading forums everyday for probably a year since I bought my evo. No one I know owns one, so I had plenty to learn. I was going to buy a Corvette and drove a highly modded evo(didn't buy it, piece of junk)and loved it, so you can imagine how much I knew about Mitsubishi's and turbo cars. It was not much. I got lucky and bought a pretty nice rs with some mods. Use the Google search. It worked better for me. I'm still learning plenty.
