Was your turbo before the rebuild very bad off? IE pouring oil due to bad seals and worn bearings? Your converter and exhaust system could be full of oil.
Was the turbo so worn out that the wheels were rubbing on the housings? Were there pieces missing from the blades?
If so, and you are still running the factory oil cooler, stop what you're doing and remove and either do away with the factory oil cooler, or replace it completely with an external one. Are you or were you running the factory oil system when the turbo took a dive?
The reasoning behind the oil cooler replacement is this, it is physically impossible to completely flush the factory oil cooler located in the radiator. Any particles of bearing material or seal material that came from your turbo, will get stuck in the factory oil cooler. Over time (typically 1-2 months of steady driving) those particles will leach their way back into your oil system, back to your freshly rebuilt turbo and eventually down to your main and rod bearings. Especially if the motor has high mileage and runs the factory oil filter and oil feed line. Not too mention the pieces that were blown into your intercooler and will eventually be blown directly into your motor. The factory oil feed line to the turbo, sends unfiltered oil to the turbo at all times. This is why it is so important to run the Oil Filtration system like the one PTE sells on these cars. This system replaces the factory oil feed line and replaces it with a line that taps directly from a remotely mounted oil filter adapter flange. This way, the turbo will see filtered oil.
Couple of last questions. How many miles have you put on the car since the rebuild and when did you start noticing the smoking? Did you happen to notice what color the smoke is? How many miles are on the car now?
Let us know and hope some of this helps.

everything from what o know is stock including the oil cooler. when the turbo was taking apart it was grinded down and the turbo guy said it broke in half..
also i drove about 2 miles on the rebuilt turbo before it started smoking. drives fine until i really step on it. i am a new gn guy love the car but dont know any good mechanincs in sacramento,ca Where is a good website to order a new oil cooler and other parts?

The oil cooler in your radiator will just have to go unused as you can't remove it unless you completely replace your radiator with an expensive factory replacement. You might want to look into replacing it with an external like the ones that Jegs sells. Oil Coolers - JEGS
I'm not exactly sure what the threads are for the factory oil cooler lines are. Maybe someone will chime in here with that info, or you can just completely remove the factory oil cooler by draining the oil, removing the oil filter, and removing the fitting/nut that the oil filter screws onto. This nut not only is used for the oil filter to screw onto, but it also holds the oil cooler line adapter housing to the oil pump. Once you remove this nut, and pull the adapter off the oil pump, making sure that the O-ring behind the adapter is not left on the oil pump housing, the threads that are left are the same as a standard PF47 or PF52 oil filter. Again, make double sure the O-ring is not sticking to the oil pump housing and doesn't get sandwiched between the oil filter and oil pump housing. Don't ask me how I know this...
The factory oil cooler was really over kill to start with and there are no downsides to not running one. I ran without one my my old grey car for years, and there are a lot of others out there that do away with it. On my new 87 T that I just recently acquired, this was one of the first things I eliminated. No problems.
As far as the smoking issue goes, who did the repair? Was it someone who repairs turbos 24/7? Are you still running the factory catalytic converter?
Maybe some others will chime in with other ideas as well.
