New to Imports.....Suggestions?

Haven't really put much thought into what I want to spend. I usually put an action plan together then, buy parts when money allows (if necessary).

Do you have any specific vendors/part numbers you could recommend? I've visited a few different web sites but none of them list parts specifically for my car. I'm assuming because it is a recently introduced model, but I'm sure some of the listings are compatible.

When you say intake I'm assuming you mean an induction system not the entire intake manifold, right? If not, I could use some direction there as well!

How do these cars generally react to nitrous?
...Superchargers?
...Turbos?

Thanks for the help!
