If he has paperwork check the compression and leakdown on the engine. I can't remember the exact numbers but check w/ heavy throtle and they can give you the info. Also look for shipping damage that may affect the internals. Dented oil pans are most common and look at the overall condition is it dirty, rusty, stored indoors or out, etc. Check the turbo if you see fine white lines in it she has been cooked and count on spending at least $300 to replace it check the exhaust mainfold also for cracks and signs of exessive heat from running lean ::too much boost:: Look for an exessive amount of tees taped into vacuum lines ::gives an idea if he was running a BC::
The harness can be had from JimWolfe Tech for a pretty penny but see if HT can score you one but either way look to spend $500 for the harness.
As for the IC piping think of it a good reason to get a FMIC I wish I could afford one. (bigger injectors also <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='
