Sweet geebuz I think this trumps Ryan's carnage pics!
Brandon, is there anything in your entire intake tract that may have busted loose? A piece of silicone coupler, fin of FMIC, etc? Part of the BOV perhaps? Looks like something small got in there and was obviously obliterated or it would have taken out the turbine on the way out.....did you check that too?
Was the car sitting for any length of time w/o something covering the intake piping/IM inlet? Perhaps something small fell in there as you were swapping TB's....Gasket material or something?
Dude this sucks pretty hard, and like I said before I have a head for ya. If you have time Thursday night you can come take a look at it if ya want!
Also, check the oil pan. Your culperate might be sitting at the bottom (fell through the hole in the piston)?
