New turbo smoking from top

I have the vehicle listed above Speed3. So a new turbo was installed two days ago a stock one. And a hpfp as well. So when I been driving the car some smoke has been coming out from where the down-pipe and turbo area is at it a decent amount of smoke. The car turns on well no check engine light or stuttering. The only times the smoke comes out is when the car has been driven a long time and the engine is hot. Before when it had the old turbo no smoke came out at all but since this turbo has been on it smokes. I do not know what the problem can me.
