Just got a '08 WRX a couple months ago. Unfortunately I have always been poor/without the means of learning basic engine and turbo mechanics and modifications. This is not longer the case but of course I am now at a disadvantage because I don't know anyone into modifications and am not sure where or how to begin. Though I don't know much about my WRX I am a jet engine mechanic so I have an in depth tool selection know-how and can easily understand engine systems and I've been told it is much easier to go from jet engine to learn a car engine then visa versa. So basically what I am asking for are other ways to learn the basics of engine/turbo systems and basic mods to improve performance such as in depth forums, threads, articles, videos, and so on.. Any advice is appreciated!
