Dave,
I looked into a 5-lug swap recently. I was actually going to pull the trigger on a complete E30 M3 five lug setup but decided it wasn't a big enough upgrade to justify the cost. A custom or E36 method is still in the books, but it seems that the 5x120 options are more limited in terms of less expensive light-weight wheels?
I was going to go for the OZ ultraleggera 16" ones down the road. Intending on looking into some of the BBKs out there for the stock 4 lug setup (like Lee's Massive Brakes).
As for sourcing an F22c, I have come to find it's either one of these three options:
1) local salvage yard that I was referred to by my body shop guy (trustworthy from past work) that can source me the engine, transmission, and accessory harness for $5K - I can do a compression test upon it getting to his yard, but after that there is not warranty or anything
2) Ebay - found a couple of places sourcing them and one in Florida has a few (

Plus an "F" for their BBB rating. Their Ebay score seems decent (whatever that is worth), and they have a complicated warranty policy that is disadvantageous to me, but it's better than nothing I suppose.
3) Try to find one locally from private seller who wrecked his car - most unlikely due to small numbers of 04/05 F22Cs (need cable-driven one), especially locally
With the Ebay stores, if I plan on going with them, I would ship them to a shop out here an have them run a diagnostic and tear the engine apart to look things over. It could be anywhere from $250-550 dollars for a full inspection of the entire engine and its internals (labor). Worth it in the end in my opinion for piece of mind. At least then I have somewhat of a chance to get an exchange/return if the engine is defective.
Any suggestions on the sourcing aspect?
