Don't crank it up and you really need to quit talking to dealers. My suggestion is to pull the airbox to turbo hose and check the turbo shaft play. If it moves more than a tiny bit fore/aft and a bare hint side to side then the turbo is shot. If the shaft doesn't move as described check for a split/cracked high pressure oil feed line (the skinny one) or a loose connection (upper end likely as the lower end is a simple push into the block fit) on the oil drain line (no split/crack likely as this is just gravity feed).
Assuming the turbo is shot:
1. forget any exhaust manifold issue. There has been no change. Assuming they even have the right part #, which I doubt, an "R" prefix normally means re-manufactured which makes no sense for a manifold.
2. replacing the turbo is a 1-2 hr job under decent working conditions which may be a problem for you unless you can drag/push it into a heated garage or otherwise get it under cover somehow without cranking it up.
3. idParts (
http://idparts.com/catalog/index.php?cPath=117) has everything you need and ships across the border
4. what do you need - 1) turbo from idParts; 2) forget the 4 pinch nuts just get appropriate size grade 5+ nuts and lock washers at a local parts store; 3) turbo to manifold gasket from idParts; 4) copper crush washers for oil feed line from local parts store; 5) upper gasket for oil drain line from idParts or cut your own; 6) oil drain line to block push "gasket" probably the current one can be reused or you can get from idParts, I think, or a local dealer (cost should be ca. $10 US). If the oil feed and drain lines are solid they can be reused with suitable new washers/gaskets although I'd advise flushing them with like carb cleaner just because. If they need replacing get from idParts.
The main thing to be aware of doing the job, it's pretty obvious bolting/unbolting, is that the combination of OEM pinch nuts and OEM exhaust manifold studs can be a significant problem as geordi and I well know. If the turbo is shot then while you are waiting on parts to get in on a daily basis give each of the 4 exhaust manifold stud nuts a good soaking of penetrating lube (PB Blaster or some such). That will hopefully free up the nuts so you don't break studs removing the nuts. If studs do break your local parts store can provide replacements.
