stumpped on idle and smoke.
ok so did a compression check today and both rotors come out at 90 (this engine is a s4 t2 stock ports with emissions removed and 0 miles since rebuild.) it smokes hard wont idle and leaks oil like no other im gonna pull the turbo tonight and see if it is just the line(s) or if the oil is coming from the block any other suggestions.

Stock turbo? No gunked-up hardlines or restricted oil cooler lines? How do the oil injector lines look coming from the oil metering pump? How did you seal the oil pan? What did you use, etc...? (Getting that thing fully sealed can be a bitch sometimes.)
Sorry for all of the questions... Just need a bit more information.

I was in a hurry my bad, pan is sealed with gasket that came with my rebuild kit, has a stock ht18 hardlines seemed fine when I put them back together and im running premix cause this is supposed to be a track only car i was messing with it and it only seems to leak when I run it for a few minute, the oil seems to bebudget coming out the bottom of my turbo mani it is also leaking from my dp where my dp and exhaust connect.

Oil leaking from around the manifold and out the exhaust flanges... there's almost only one thing it could be. That is, if like Karack said, you didn't let it run long enough to let all the residual oil burn off.
If that were the case though, you'd probably not experience more leaking when running. Take the turbo off and see if you can see a trail coming from between the turbine housing and CHRA, and also see if the turbine looks wet.

most assembly lubes will burn off within the 30-45 minute range, the engine will have a difficult time idling on it's own depending on the condition of the parts reused.
if it's still spewing oil and chugging to attempt to idle after that amount of time then yes, you screwed something up. like a non professional port job that ate into the oil seal channel or pinched oil seal during assembly or overly cheap rebuild reusing oil seal o-rings that have now bit you in the ***.
it's unlikely the turbo oil seals failed if the turbo wasn't bad before the rebuild. but to verify if it was your rebuild pull the plugs first and see if they are wet with engine oil, if so tear the motor apart and find your mistake. if not, pull the turbo and see if the oil in the exhaust is isolated to within the turbo pointing to a turbo failure.

Ok a little bit of oil on trailing plugs but they don't feel viscous and smell like gas so I think that might be my 2 cycle oil for my premix. Along with the fact that its black and I have not had this car running long enough at one time to turn the engine oil black. Its still copperish on the dipstick. So gonna pull the turbo later sourced another one to bolt on and try out. Gonna have to wait though somebody stole some high dollar stuff from me today while I was working and im waiting for the cops so I can file a police report. Lmk thoughts and opinions on car issue.

Exactly. Before spending any money on anything, pull the turbo off real quick and see if it's the culprit. You've already pulled the spark plugs and the results seemed inconclusive. If it's a problem w/ your turbo, it'll show signs of leaking out the exhaust housing and the turbine blades will be wet with oil. If it's a problem with the engine build, you'll probably see oil in the exhaust manifold and through the turbo.
