Don't hang me or flame me for asking, but....

Header, Turbo housing, Downpipe, charge pipes, etc.

What can be powdercoated and what can't?

Also keep in mind that I'm not looking at a monster track set-up, only looking at 200-220 WHP.

What kind of possible heat related or cracking problems?

thats a good question actually, im not a pro at this, but id recommend jet coating the hot side and DP, and the compressor side and charge piping would be better to powder coat. someone might have better info, but thats what i would do.

manifold, turbine housing, and downpipe can be ceramic coated. compressor housing, intercooler piping, and pretty much anything else can be powder coated.
